do touch screen monitors work any computer manufacturer
The best touch screen monitors allow you to interact with your desktop computer via tap, swipe and pinch-to-zoom. Alternatively, you can install it as a secondary monitor to use with an office-based laptop.
In this article, we"ve gathered together the best touch screen monitors available today – in a range of sizes from 21 inches to a special ultrawide monitor(opens in new tab) that"s 49 inches. If you"re after a smaller secondary monitor that can be carried with your laptop for use on the go, see our list of the best portable monitors(opens in new tab). (Portable monitors can also be had with touch sensitivity, but they"re smaller and are powered by your laptop"s battery, so they don"t need their own power supply.)
If you"ve already researched the best monitors for photo editing(opens in new tab) or the best video editing monitors(opens in new tab), you may have realized that none of them are touch screen monitors. But why not? Why would you consider choosing a new monitor without touch sensitivity?
After all, the best touch screen monitor will add an extra, more ergonomic form of user input, so must be better, right? Well, it"s not quite that simple. At the bottom of this page, you"ll find tips on what to look for when buying a touch screen monitor, including connectivity, size, and that all-important image quality.
Dell"s P2418HT has fairly typical touch screen display credentials: a 23.8-inch screen size and Full HD (1920 x 1080) resolution. But it stands out from the crowd in other areas.
Its special articulating stand transitions the display from a standard desktop monitor to a downward 60-degree angle touch orientation. It also supports extended tilt and swivel capabilities, so you can adjust the screen to your task or a more comfortable position. Plus, a protective cushion at the base of the screen offers a buffer against bumps when the stand is fully compressed.
Marketed at commercial and educational settings as well as home use, the TD2230 boasts a 7H hardness-rated protective glass for extra scratch protection and durability. Super-thin screen bezels give the panel a modern, sleek look, plus there are integrated stereo speakers for added versatility.
The ViewSonic TD2230 boasts upmarket image quality thanks to its IPS LCD display that provides better color and contrast consistency, regardless of your viewing position, while the 1920 x 1080 screen res is high enough for crisp image clarity when spread across the 21.5-inch panel size. 250 cd/m2 max brightness and a 1000:1 contrast ratio are pretty typical, while HDMI, DisplayPort and analog VGA connectors ensure you"ll be able to hook this monitor to pretty much any computer running Windows 10, Android or Linux.
Want a larger than average touch screen monitor? This 27-inch offering is our pick, as it"s based around an IPS LED-backlit display. That translates more dependable color accuracy and contrast that won"t shift depending on whether you"re viewing the centre of the screen or the corners.
The Full HD resolution is spread a little thin across a 27-inch display, so images will look slightly pixelated, but this is an unavoidable compromise you have to make if you want a touch screen monitor larger than 24 inches. The PCT2785 does score well in terms of versatility though, as you get a built-in HD webcam and microphone, making it great for homeworking(opens in new tab) and video conferencing.
The T272HL boasts a slightly above-average 300cd/m2 brightness, along with 10-point capacitive multi-touch. There are also a pair of 2w internal speakers, and the stand allows a large 10-60 degrees of tilt to enhance touch ergonomics.
If you"re after a larger-than-average touch screen monitor, the T272HL is a reasonable choice, but there are compromises to be made. For starters, this is still a 1920 x 1080 Full HD monitor, so while it may be physically larger than a 23/24-inch Full HD display, images will simply look larger, not more detailed.
If you can get past the uninspiring black plastic design of the Philips 242B9T, this touch screen monitor has a lot to offer. It should be easy to connect to pretty much any computer, thanks to its full array of HDMI, DVI, VGA and DisplayPort connectivity and included cables for all but DVI. It"s even got its own built-in 2W stereo speakers, while the clever Z-hinge stand allows a huge -5 to 90 degrees of tilt adjustment, making it extra-ergonomic when using the 10-point capacitive multi-touch display.
At 21.5 inches, the Asus VT229H is one of the smaller touch screen monitors on this list, but it still sports the same Full HD (1920 x 1080) resolution as larger 24 and even 27-inch touch screen displays, meaning you get more pixels per inch and slightly crisper image quality. This is also an IPS LCD, with wide 178 x 178-degree viewing angles and reliably consistent color and contrast, regardless of your viewing angle.
Most touch screen monitors are just that: a monitor, with a touch interface. But this 21.5-inch display also adds a pair of 2W stereo speakers for sound output, along with dual-array microphones and a built-in webcam for video conferencing. The IPS LCD display panel ensures decent color and contrast uniformity, while the Full HD 1920 x 1080 resolution is easily enough to for crisp image quality on a screen this size.
The square black exterior is typical of Lenovo"s business-orientated products and may not be to everyone"s taste. Plus you"ll need to connect via DisplayPort only, as there"s no HDMI input. But otherwise this touch screen monitor offers a lot for a very reasonable price.
The obvious drawback with a touch screen monitor is the aforementioned size restrictions because if you want one larger than 27 inches, you"re out of luck. The next step up in size for touch screen monitors are 50+ inch displays designed for corporate presentations rather than home computing.
Even most 27-inch touch screen monitors have the same Full HD 1920 x 1020 resolution as their smaller 21-24-inch stablemates. So you"re not actually getting more pixels, only bigger ones. This can make your images just look more blocky unless you sit further away from the screen.
It"s not just outright screen resolution where touch screen monitors can fall short of their non-touch alternatives. Top-end screens designed for image and video editing are often factory color calibrated: they use LCD displays that can display a huge range of colors, or feature fast refresh rates for smoother video playback and gaming. However, touch screen monitors aren"t intended for color-critical image or video work: they tend to be all-purpose displays designed for more general applications like web browsing and basic image viewing.
Connectivity also tends to be compromised on touch screen monitors. You can forget about USB-C hubs(opens in new tab) with Power Delivery, and even DisplayPort connections can be a rarity.
These are the two primary forms of touch input. Resistive touch requires you to physically press the screen (which itself is slightly spongy) for it to register an input. It"s a cheaper form of touch input, and a resistive touch screen is also tougher than a capacitive equivalent, so they"re popular for use in ATMs and retail checkouts.
However, resistive technology doesn"t support multi-touch and won"t give the same fluid sensitivity as the touch screens we"re now accustomed to on phones and tablets. Consequently, most modern touch screen monitors use capacitive touch screens supporting 10-point multi-touch. These operate exactly like a phone or tablet"s touch screen, requiring only a light tap, swipe, or pinch to register inputs. All the monitors on this list use 10-point capacitive touch screens.
Put simply, even the best iMacs(opens in new tab) and MacBooks(opens in new tab) don"t support touch screen monitors. Consequently, all the touch screen monitors on this list will only work with Windows 8.1, Windows 10, and some Linux and Android operating systems.
Not all LCD monitors are created equal. LCD displays use three types of construction - IPS (In-Plane Switching), VA (Vertical Alignment), and TN (Twisted Nematic). Each one of these three LCD types exhibits noticeably different image quality characteristics, clearly visible to the average user.
For image and video editing, TN-based monitors should really be avoided. These are the cheapest to manufacture and deliver compromised image quality thanks to their restrictive viewing angles. This results in highly uneven color and contrast across the screen, effectively hiding shadow and highlight detail in your images. IPS-based monitorsare the gold standard for image quality. These produce color and contrast that doesn"t shift depending on which part of the screen you look at, making image editing much more precise. Most of the touch screen monitors on this list are IPS-based, and the rest are VA-based monitors. These can"t quite match the image quality of an IPS monitor but are much more color-accurate than a TN screen.Round up of today"s best deals
I need to replace my PC setup at home, so your article on buying a new family PC was really great for me. Currently the PC is only used by the children for accessing the web, running Minecraft, iTunes, playing The Sims etc. I would really like to try using a touchscreen monitor to get the best out of Windows 8. I am aware of the argument about gorilla arms, but after using an iPad, I find myself prodding all computer screens with an (unrealistic) expectation that something should happen.
You can add a touch-sensitive screen to any PC – or even an old laptop – by buying a touch-sensitive monitor. There must be a market for them, because most leading monitor suppliers offer them. This includes Acer, AOC, Asus, Dell, HP, Iiyama, LG, Samsung and ViewSonic. The less well-known HannsG also has competitive offerings.
However, touch sensitivity requires extra technology, which is an extra cost, especially for large screens. Touch-sensitive monitors are therefore more expensive than traditional designs, which must restrict the size of the market.
As you have found, there are lots of all-in-one PCs with touch screens, but they are basically laptop designs with separate keyboards. Slimline designs impose thermal constraints on the processor, which will typically operate at a TDP between 15W and 35W, or less. The processor will be throttled when it gets too hot, and the PC may shut down. By contrast, spacious desktop towers can use processors that run at 45W to 90W or more, so you get more performance for less money.
Towers provide space for adding more memory, ports, faster graphics cards, extra hard drives, optical drives (DVD or Blu-ray) and so on. They are also much easier to repair, so they should last longer. The main drawback is that they take up more space than laptops or all-in-one designs. This may be critical if you want to mount the screen on a wall, which is common with touch-screen PCs used for public information access.
You must consider the flexibility of the design. While the “gorilla arm” argument is simplistic to the point of stupidity – teachers have been using blackboards for centuries – there are important considerations to do with screen distance and angle.
The better all-in-ones provide flexibility to handle different programs and different uses. Often the screen leans back, and in some cases, can be used in a horizontal position. This makes it practical to play electronic versions of family board games, navigate around maps, play a virtual piano, and so on.
Desktop monitors are usually designed to be used with the screen in a vertical position, and relatively high up. This puts the screen a long way from your hands, so you are less likely to use it for touch operations. This contrasts with using a laptop, where the screen may be as handy as the keyboard.
If you decide to go for a touch-screen monitor, choose one that is easy to tilt backwards and possible to use in a horizontal position. Obviously, you should be able to return it to an upright position for word processing and so on.
Alternatively, you can buy any touch screen you like, if you mount it on a monitor arm that enables the screen to be moved around. This may actually be a better option, but it will probably cost more.
Touch-screen monitors are a bit more complicated than traditional designs, because they are active rather than passive devices. Traditional screens just have to show a picture, whereas touch-screen monitors have to feed information back to the PC. They often do this via a separate USB cable that runs next to the VGA/DVI/HDMI/etc video cable.
Monitors also vary according to the number of touch-sensitive points. This can range from five to 40, but 10 is usual for Windows 8. Further, different monitors may use optical, resistive or capacitative touch technology. Capacitative touch provides the same experience as using a tablet, which is what you want.
Some monitors support a new standard: MHL (Mobile High-definition Link). This enables you to connect a compatible smartphone or tablet to the monitor to show videos with high-resolution sound (up to 7.1 channels, including TrueHD and DTS-HD). The mobile device gets charged while it’s attached.
Other considerations are the usual ones: screen size and resolution, brightness, type of technology (LED, IPS etc), number of ports, whether it includes loudspeakers, and so on. Since you’re a developer, you’ll probably want to knock out a quick spreadsheet to compare all the options.
Note that touch-screen monitors designed for Windows 7 – probably with two touch-points – are less than ideal for Windows 8, where the bezel has to be flush with the display for edge-swipes. However, I don’t expect there are many Windows 7 touch monitors still on the market.
I have very little experience of different touch-screen monitors, and haven’t tested any, so you will need to do your own research. I can point to some of the products that are available, but unfortunately it may be hard or impossible to see them before you buy one.
PC World, for example, only seems to offer three touch-screen monitors. These are all Acer models with Full HD resolution (1920 x 1080 pixels) and screen sizes of 21.5in (£179.99), 23in (£249.99) and 27in (£379.99). These have MHL support, USB 3.0 and tilt stands that adjust from 80 to 30 degrees, so you could do worse. The 23in IPS-screen Acer T232HLA looks like the best option.
Other touch-screen monitors that might be worth a look include the 23.6in AOC Style i2472P (£262.98), the 21.5in Dell S2240T H6V56 (£207.38) and the 23in Dell S2340T (£339.95). There’s also a ViewSonic TD2340 for £199.99, apparently reduced from £439.99, and a 24in Samsung S24C770TS for £449.99.
If you have a modern Windows 8 laptop, then you can probably use Windows 8’s touch gestures on its built-in touchpad. In the same vein, you could just buy a touchpad for your desktop PC and use it with a cheaper non-touch screen. Logitech’s rechargeable Touchpad T650 is an expensive option at £114, though the wireless T650 looks a better buy at £39.99.
Touchscreen desktops are a surprisingly controversial subject. While the high tech community, like Microsoft, adopted a ‘yes we should because we could’ reasoning, many users strongly disagree. This has somewhat contributed to the sweeping dissatisfaction with Windows 8. Transitioning to touchscreen desktops is going to be a difficult process.
It is an understatement to say it won’t be worth it. Touchscreen technology, as anyinnovationin input technologies, has the potential to change and expand the way we interact with technology. The conflict seems to be about whether touch has the potential to replace other input devices. Ironically, this is actually not the primary goal or purpose of touch technology.
There are a number of specific issues raised with touchscreen desktop computers. The inevitable flaw of using your display as an input device comes to mind immediately. Your hands block your view.
The main issue one sees when looking through tech blogs, however, is the dreaded “gorilla arm”. This particular issue is extremely common, and can be seen anywhere from the lowliest tech blog to the Scientific American.
Screens are vertical and usually located farther away, making it harder to use them. Clearly, humans will never overcome this obstacle, thus making touch technology pointless for laptops and computers. Steve Jobs himself said “Touch surfaces don’t want to be vertical”. But that didn’t stop Steve Jobs from using touchscreens, and it won’t stop Microsoft, or HP, or anyone else from jumping on the bandwagon.
The fallacy is at the heart of the idea that gorilla arm is some sort of major obstacle to the introduction of touchscreen technology for desktops and laptops. This is of course, if your display has any reason to be vertical. This is what a modern touchscreen desktop looks like…
Obviously, a touchscreen computer will not be designed the same way as older models. Both the hardware and the software will be tailored to it. Manufacturers are already adapting the combined input and display device. This essentially means that you won’t be dealing with a raised screen that is parallel to your face. With Windows 8, Microsoft has adopted, perhaps a little prematurely, the stance that operating systems should assume all users will have a touchscreen interface.
So when is it time to get touchscreen computers for your business? This question really depends on the nature of your business. If you have a company full of employees primarily dealing with spreadsheets and databases, this probably won’t help you at all.
Any less data-centered, less keyboard heavy work, however, can benefit from touchscreen computers. Perhaps the most obvious of these is the retail industry, which has already largely adopted it as a standard.
If your company relies heavily on young employees, you will find that, after growing up with iPads and iPhones, they will expect, and work better with, this type of technology. We’re not quite there yet, but when you find yourself teaching the masters of new technology to use your old tech, it’s time to upgrade. It will be a matter of a few years at most.
Most pressingly, however, is the simple fact that the industry is going to force you. Consumers want touchscreen technology, and unless you intend to start fiddling with Linux, operating systems will leave you behind.
Windows 9 is not going to be less touchscreen oriented than Windows 8. Running old programs on an old computer using an old operating system is no recipe for business success.
In your business you can install touchscreen desktops which are highly likely used by everyone in ways that a traditional workstation is not suited for. Touchscreens are far more intuitive to use, and do not necessarily require a mouse and a keyboard. This means that you could set up a few touchscreen desktops for your customers to browse merchandise without putting your entire selection physically on display.
Information can be made available to your customers on the spot. For example, the display will provide information such as which sizes or colors are in stock, and best of all, price comparisons with major competitors. This information can all be displayed to your customers at a tap on a screen.
Touch is efficient. Surely you can currently do everything that computers do with a mouse and a keyboard. However, from a negative standpoint you have ten fingers whereas there is only one mouse pointer. Back in the 80’s when the mouse was first introduced, many people wondered why they would want that. Operating systems at the time were built so you could do everything with a keyboard, so why invent a mouse? It sounds like an absurd line of reasoning looking back.
How many people run a DOSBox out of disdain for the mouse? Operating systems and computers integrating touch will have new capabilities and programs designed to do awesome things, opening up a new frontier in our technology. So don’t panic. Because integrating touch will not mean removing other inputs unless they naturally fall by the wayside as our technology moves beyond them.
People have become increasingly accustomed to touch screens powered by electricity. We regularly use touchscreen technology on our phones, PCs, ATMs, and grocery store checkout lines. Touch ordering and payment at the table have become commonplace. Unfortunately, few of us can explain how a touchscreen monitor works.
Users can interact with a computer by touching the screen with their fingers or a stylus. You can navigate a graphical user interface (GUI) without using a mouse or keyboard. The touch screen can detect a touch inside the display area. A sensor, controller, and software driver are the three essential components.
Touch screen devices include computer and laptop displays, smartphones, tablets, cash registers, and information kiosks. Touchscreen monitors have become more common since their cost has progressively fallen over the last decade.
A touch screen is a display device that allows users to interact with a computer using their finger or stylus. They"re a useful alternative to a mouse or keyboard for navigating a GUI (graphical user interface). Touch screens are used on various devices, such as computer and laptop displays, smartphones, tablets, cash registers, and information kiosks. Some touch screens use a grid of infrared beams to sense the presence of a finger instead of utilizing touch-sensitive input.
The idea of a touch screen was first described and published by E.A. Johnson in 1965. In the early 1970s, CERN engineers Frank Beck and Bent Stumpe developed the first touch screen. The physical product was first created and utilized in 1973. The first resistive touch screen was developed by George Samuel Hurst in 1975 but wasn"t produced and used until 1982.
Today, all PCs support the ability to have a touch screen, and most laptop computers allow users running Microsoft Windows 10 to use a touch screen. Also, many all-in-one computers are capable of using a touch screen. Computer manufacturers with touch screen products include Acer, Dell, HP, Lenovo, Microsoft, and other PC manufacturers.
There are also some high-end Google Chromebooks with touch screens. However, to help keep the costs lower, many Chromebooks do not have touch screens.
To help keep costs lower, not all computers and laptops come with a touch screen. If a touch screen interests you, make sure that it"s mentioned in the product specifications. If it"s not listed, the computer likely does not have a touch screen.
If your laptop screen is not touch-capable, there is no way to change the screen to be a touch screen. The laptop must come with a touch screen when originally purchased to have that functionality. When purchasing a laptop, and you want touch screen functionality, check if it includes a touch screen before buying.
If your desktop computer monitor is not touch-capable, there is no way to change the monitor to be a touch screen. You need to purchase a new monitor that includes touch functionality. Before purchasing a new monitor, verify the operating system on your computer also supports a touch screen.
Tap - A single touch or tap on the screen with a finger opens an app or selects an object. Compared to a traditional computer, a tap is the same as clicking with a mouse.
Double-tap - A double-tap can have different functions depending on where it is utilized. For example, double-tapping the screen zooms the view centered at the tap location in a browser. Double-tapping in a text editor selects a word or section of words.
Touch and hold - Pressing and holding your finger to a touch screen selects or highlights an object. For example, you could touch and hold an icon and drag it somewhere else on the screen. See our long press page for further information on this term.
Drag - Pressing and holding your finger on a movable object, such as an icon, you can drag your finger to "pull" the object to a different location. The same action, used with text, lets you highlight text. Lift your finger when you are done moving or highlighting.
Swipe - Swiping your finger across the screen scrolls in a certain direction or change pages. For example, pressing your finger at the bottom of the screen and quickly moving it up (swiping) scrolls the screen down. See our swipe page for further information and related links.
Pinch - Placing two fingers on the screen in different spots and then pinching them together zooms in. Pinching your fingers together and then moving them away from each other zooms out on the screen. See our pinch-to-zoom page for further information on this term.
Any computer device (including a touch screen) that takes input from the person operating the device is considered an input device. The way you use your finger on a touch screen is very similar to how you use a computer mouse on a desktop computer.
Technically speaking, a touch screen is an input/output device. Not only is it capable of accepting input, but it also displays the output from the computer.
One of the most significant differences between a mouse and a touch screen is the ability to hover. Almost all touch screens can only detect input when your finger is in direct contact with the screen. However, a computer mouse uses a cursor that allows the user to view the information by moving the pointer over an object but not clicking it. For example, this link to Computer Hope shows the text "Visit the Computer Hope Page" when hovered over using a computer mouse. However, a user with a touch screen cannot see this text because it opens the link if they place their finger on the link.
Some web pages and apps may simulate the hover feature by making the first tap do the hover feature and the second tap open the link or app. Also, some Apple devices use Force Touch, which offers features similar to hovering.
Not all touch screens are the same. Different technologies are used to allow a user to interact with a screen. Some technologies may work with only your finger, while others may allow other tools, like a stylus. Below is a brief description of each of these technologies.
A capacitive touch screen is coated with a special material that stores an electrical charge monitored by circuits at each corner of the screen. When you touch a capacitive touch screen, a small amount of the electrical charge is drawn from the point of contact to indicate where you touched the screen.
To use a capacitive screen, you must use your bare finger or a specially designed capacitive stylus. Most users experience this type of screen technology when attempting to use a smartphone touch screen while wearing gloves and cannot do anything.
A resistive touch screen is coated with a metallic electrically conductive and resistive layer that detects the pressure of your finger or another object. This technology is often a more affordable solution than capacitive but can be damaged by sharp objects touching the screen.
A SAW (surface acoustic wave) or surface wave touch screen sends ultrasonic waves and detects when the screen is touched by registering changes in the waves. This technology is more advanced than the other two but does not work with hard materials and can be affected by outside elements.
Infrared touch screens utilize a matrix of infrared beams transmitted by LEDs with a phototransistor receiving end. The infrared beam is blocked when a finger or other object is near the display. That interruption gives the device input to where your finger or another object is positioned.
Touch screens utilize a virtual keyboard to input letters and numbers that allow the user to tap the virtual keys with their finger. Also, devices like smartphones and tablets have voice recognition that inputs information into the device.
In all forms of writing, touch screen and touchscreen are both valid spellings. If used as an adjective, the word may be hyphenated, e.g., "touch-screen devices."
Touchscreens aren’t just available for laptops and mobile devices: There are many desktop monitors that include touchscreen capabilities for those who like to tap and swipe. This can make managing more complex tasks easier, and touchscreens are often preferred by designers and other professionals taking an active approach to their work. Here are the best models.
Dell’s touchscreen display is more than meets the eye: This 24-inch monitor has a sturdy base when upright, but can also collapse down at an angle for more serious touchscreen work whenever you want. That also makes this monitor an excellent choice for either a primary display or a secondary monitor to link up and use for specific, touchscreen-oriented tasks when needed.
As for specs, the Dell P2418HT offers a 1080p resolution 6ms responsible time, and 60Hz refresh rate. It can reach up to a brightness of 250nits as well. Connections for the model include HDMI, DisplayPort, and DVI. Anti-glare coatings and blue light filters also make it easier on professionals working throughout the day.
Those looking for a more affordable desktop monitor will appreciate this Asus 22-inch monitor with touchscreen capabilities. While not loaded with features, the 1080p monitor is well-prepared for a full day of work with a study design and all of Asus’s eyecare software to help manage backlighting and flickering for the best experience.
The Asus VT229H offers up to a 75H refresh rate, brightness up to 250 nits, and connections that include both HDMI and VGA. With its smaller size, it serves well as an accompanying touch monitor in a professional setup or can work as a primary display when space is limited and a touchscreen is a vital feature to have.
If you already know that you need your primary monitor to have touchscreen capabilities, check out this full-sized, 27-inch model from ViewSonic. It offers 10-point multitouch capabilities for every kind of touchscreen control option, and the 1080p panel is made to be durable. This is another model that offers a dual-hinge design so you can angle back or lay it flat against the table depending on how you prefer to work. Oh, and if you’re using something like a Mac Mini, it offers full compatibility with MacOS too, so you won’t lose any touchscreen capabilities.
Designers will appreciate a number of features on this 24-inch Planar model: Once again, a dual-hinge design makes the monitor ready for work at any angle, and light filters help reduce flickering and blue light for the sake of your eyes. We’re particular fans of the smooth, stable design of this monitor, which is important when the hinges see frequent use over time and need to last for years.
Some types of PC touchscreens are made to be portable. These smaller displays take only seconds to set up, allowing them to serve as a secondary display for almost any occasion, from working with your laptop to helping out in a flexible office situation. This 1080p Asus model measures 15.6 inches and easily collapses down, similar to a tablet, for quick carrying around or storage. It also has a built-in 7800mAH battery so you don’t have to worry about managing a power connection wherever you are.
The Asus ZenScreen MB16AMT includes speakers, two USB ports, both Type A and C, and Asus’ eyecare technology makes an appearance here, too. It works with pretty much any operating system you have in mind and comes with a smart cover and a stylus hole for easy storage.
Asus’ 22-inch monitor offers a high-durability glass surface and 10-point touch support that are exactly what we like to see in a touchscreen monitor made for serious work. The design also offers the ability to easily tilt to get just the right angle for your work and whether you prefer to sit or stand. AMD users will also be pleased to see that FreeSync is supported on this mode to reduce screen tearing and associated issues.
The Acer T272HL also comes with a 75Hz refresh rate, plus two built-in 2W speakers for sound. Ports include DisplayPort, HDMI, VGA, and USB-A. The Acer VisionCare software is also included here to help reduce flicker and cut down on blue light. All in all, it’s a well-rounded monitor that can help with anything from rapidly searching photo albums to playing a game.
If resolution is on the top of your list — and many photographers and designers will find it necessary — then this C-Force monitor brings the 4K resolution you want. This 15.6-inch monitor is portable enough to move it around to wherever you need it in your workspace but large enough to still be useful when handling a wide variety of subtasks (including gaming tasks or enlarging a mobile game). It also has HDR support for video optimization and FreeSync support for AMD card users. Creatives will also appreciate the 100%s RGB gamut coverage.
There’s another option for a touchscreen desktop that may be particularly appealing for some buyers – an all-in-one PC that combines the PC and monitor into one component that can save on space while still delivering a premium experience. Microsoft’s Surface Studio 2 is an excellent example of this solution. The 28-inch monitor offers a UHD resolution with full 10-point touchscreen capabilities, perfect for artists and designers willing to pay more for an all-in-one PC. It can operate in both Studio and normal mode depending on your preference and works with the innovative Surface Dial, which can help cycle through color palettes or other tricky tasks.
Inside, this Surface Studio 2 has an Intel Core 7 processor, 1GB of RAM, and a 1TB SSD for storage space (there are also 32GB versions available for extra speed). That allows the Studio 2 to run just about anything, including extra-demanding editing and photography software. It’s the complete package for professionals who want a touchscreen…something that iMacs simply can’t provide.
You interact with a touch screen monitor constantly throughout your daily life. You will see them in cell phones, ATM’s, kiosks, ticket vending machines, manufacturing plants and more. All of these use touch panels to enable the user to interact with a computer or device without the use of a keyboard or mouse. But did you know there are several uniquely different types of Touch Screens? The five most common types of touch screen are: 5-Wire Resistive, Surface Capacitive touch, Projected Capacitive (P-Cap), SAW (Surface Acoustic Wave), and IR (Infrared).
We are often asked “How does a touch screen monitor work?” A touch screen basically replaces the functionality of a keyboard and mouse. Below is a basic description of 5 types of touch screen monitor technology. The advantages and disadvantages of type of touch screen will help you decide which type touchscreen is most appropriate for your needs:
5-Wire Resistive Touch is the most widely touch technology in use today. A resistive touch screen monitor is composed of a glass panel and a film screen, each covered with a thin metallic layer, separated by a narrow gap. When a user touches the screen, the two metallic layers make contact, resulting in electrical flow. The point of contact is detected by this change in voltage.
Surface Capacitive touch screen is the second most popular type of touch screens on the market. In a surface capacitive touch screen monitor, a transparent electrode layer is placed on top of a glass panel. This is then covered by a protective cover. When an exposed finger touches the monitor screen, it reacts to the static electrical capacity of the human body. Some of the electrical charge transfers from the screen to the user. This decrease in capacitance is detected by sensors located at the four corners of the screen, allowing the controller to determine the touch point. Surface capacitive touch screens can only be activated by the touch of human skin or a stylus holding an electrical charge.
Projected Capacitive (P-Cap) is similar to Surface Capacitive, but it offers two primary advantages. First, in addition to a bare finger, it can also be activated with surgical gloves or thin cotton gloves. Secondly, P-Cap enables multi-touch activation (simultaneous input from two or more fingers). A projected capacitive touch screen is composed of a sheet of glass with embedded transparent electrode films and an IC chip. This creates a three dimensional electrostatic field. When a finger comes into contact with the screen, the ratios of the electrical currents change and the computer is able to detect the touch points. All our P-Cap touch screens feature a Zero-Bezel enclosure.
SAW (Surface Acoustic Wave) touch screen monitors utilize a series of piezoelectric transducers and receivers. These are positioned along the sides of the monitor’s glass plate to create an invisible grid of ultrasonic waves on the surface. When the panel is touched, a portion of the wave is absorbed. This allows the receiving transducer to locate the touch point and send this data to the computer. SAW monitors can be activated by a finger, gloved hand, or soft-tip stylus. SAW monitors offer easy use and high visibility.
IR (Infrared) type touch screen monitors do not overlay the display with an additional screen or screen sandwich. Instead, infrared monitors use IR emitters and receivers to create an invisible grid of light beams across the screen. This ensures the best possible image quality. When an object interrupts the invisible infrared light beam, the sensors are able to locate the touch point. The X and Y coordinates are then sent to the controller.

A touch screen has become ingrained in everyday lives of nearly all planet Earth inhabitants. Of course, the leading role is played by smartphones and tablets. However, other fields that use special purpose equipment keep abreast with the modern trends. Industry is among these fields. In industrial segment, the most popular devices equipped with a touch screen are panel computers and monitors. Typically, the questions on touch screen work arise during device operation – How to connect? How to configure? How to calibrate? etc.. Let us have a closer look at these issues.
As a rule, in panel computers a touch screen controller is defined automatically by the operating system and does not require installation of additional drivers. The only thing that might be necessary is calibration, but it must only be done when a touch screen does not work properly. See more information about calibration below. The connection scheme is somewhat different. Every industrial monitor, which is equipped with a touch screen, has an auxiliary USB or COM cable. This cable connects a monitor to the computer, which a video signal will be displayed from. The rest of the connection algorithm is similar to that of a panel computer.
Under configuration the detection of a touch screen controller in the system is implied, as well as its further proper operation. As it has been already mentioned, the operating system detects touch screen automatically. But what to do if this is not the case? First thing that you will definitely need is drivers. To get the necessary drivers, you may pursue any of the following ways:There are drivers on a disk that comes with the device.
If the disk is lost, you can download drivers from a panel computer/monitor manufacturer’s website, or if you know exactly what touch screen controller is installed in your equipment, e.g. AMT PenMount, you can download drivers from the controller manufacturer’s website.
Each manufacturer has its own website design, hence, there is no unified algorithm for downloading. However, the location of drivers on site is standardized, so you can always find drivers in “Downloads” section. First, you need to find your product on the manufacturer’s site, then look for a “Download” tab.
After transition and opening a tab, you will see a list of drivers available for download for this device. Touch screen driver is always easy to define due to its name. It should include the word “Touch”. Sometimes, all drivers are located on one large archive. It might happen, that you should decide, what OS you need a driver for. Just choose the required one and the downloading process will start.
If you want to download drivers from the controller manufacturer’s website, you should act somewhat different. Typically, manufacturers of industrial panel computers and monitors use controllers made by two companies that have already been mentioned, these are AMT PenMount and EETI. Drivers on manufacturers website are also located in a “Download” tab. You can transfer to it directly from the main page.
You have installed the drivers, and the touch screen is working. You want to move a cursor to the upper left corner, but it goes to the right bottom one. What to do? There is only one solution for such cases – touch screen calibration. Usually, the calibration utility program can be found in the same archive, where the drivers are located. Next, we will a consider touch screen calibration option on the example of one of the most popular panel computer models APPC-1740T from Nexcom.
In APPC-1740T the manufacturer uses a touch screen controller by AMT PenMount. We will install the drivers for OS Windows 7. Download drivers from the manufacturer’s official website. Unpack the archive, once the download is complete. After unpacking, you need to install this utility program. Click on “Setup” file and follow the instructions on the screen. The installation process will take a few minutes. Once the installation is complete, launch the utility program by clicking on the shortcut PenMount Control Panel on the desktop.
After launching, in the “Choose component for configuration” field the program must display a touch screen controller. That means that the utility program has detected a controller within a system and calibration may be started. In this window, you can also see the exact model of the touch screen controller on your computer. In our case, there is the model PenMount 6000 USB installed.
In this window, we need to choose a type of calibration. Typically, there are two options - standard (4-6- points) and extended (8-10 points). The main difference is the amount of contact points covered. The more points are covered, the more precise calibration will be. In most cases, the standard calibration is quite sufficient, so we will use this very option. Push the button and start calibrating.
During calibration, you need to click on the points on the screen following the instructions, i.e. click the cursor, hold, release and then move to the next point. It will take you a couple of minutes. After completion, the calibration window will close automatically. Then you may check whether the touch screen operates correctly. If everything is all right, then we may congratulate you on having calibrated the touch screen! If not, then, please contact Technical Support of IPC2U.
Science fiction has always served as a window into a potential future, namely in the way of technology. But what was once regulated to episodes of Star Trek is quickly becoming the stuff of reality. Many fixtures of these kinds of shows and books have begun to inspire real-life counterparts, including - but not limited to - touchscreen technology.
One only has to look at how far cell phones have come since their inception. Physical keyboards, like those from BlackBerry, gave people about as much of a solution as is possible for those who found themselves doing more on the devices as they became more advanced. Where tactile options came up short, touchscreens graciously stepped up to bat, providing a much fuller experience. This kind of functionality then spread to tablets, which are considered by many to be rivals of laptops and even standard PCs.
While there are still some things that are best done on a desktop computer, that does not change the fact that many users find themselves longing for the same abilities on their PCs afforded by many of their mobile devices. This is what helped breed the touchscreen monitor market, which has many viable options for people seeking the best of both worlds. With stronger computing power and a finer ability to control actions occurring in the screen, users can get more work done in new and exciting ways.
Traditionally, computer mice are what have allowed us to "touch" in a virtual context, but touchscreen monitors are changing all that. It might be said that the reason that mice were used in the first place was because the technology had not evolved to a responsive enough level to enable that natural solution. Now that people have the touchscreen technology, they want it everywhere.
If one thing is for certain, it is that the burgeoning adoption of touchscreen technology is no fad. Proliferation has already come too far to turn back now, and computer manufacturers are taking notice. Everyone is trying to get a piece of the action, including ELO Touch Solutions, Laiputuo Electronics, Planar, HP, 3M, Touch Systems, ViewSonic, Dell and ACER as well. Getting into the touchscreen monitor game is a no-brainer for the companies involved in this generation of computing. With so many different applications made for touchscreen monitors, options exist for all sorts of interested parties.
Touchscreen monitors are becoming the new standard in both private and enterprise settings. Here are some of the ways they can be leveraged effectively for business: touchscreen monitors for workstations, touchscreen monitors for hospitals, and touchscreen monitors for POS systems.
Newegg offers a large selection of touchscreen monitors which vary according to the type from 5-wire Resistive touchscreen monitors, and Accu Touch touchscreen monitors, to Capacitive touchscreen monitors, and more. Newegg’s wide selections will definitely meet your needs.
H.P., Dell, Intel and Microsoft expect that when companies and consumers increase their spending, touch technology will be one of the things that nudge them to upgrade. Computers with the special screens will probably cost consumers about $100 more than standard machines.
H.P. has been selling a PC with an early version of touch technology. The $1,150 TouchSmart PC has been popular, H.P. says, particularly in kitchens as a family computer. But outside of science-fiction films, touch computers have been met with lukewarm reactions. Tabletlike computers that ship with plastic pens for marking on screens remain a niche in the overall PC market, as do pure touch machines. Mr. Ben-David said that about two million of about 300 million PCs sold last year were touch computers.
H.P. has already been pushing touch technology to large businesses. It sells a custom touch interface for both desktops and laptops. Customers can turn these machines into bespoke kiosks for, say, ordering merchandise at a sporting event or flipping through a menu while waiting at a restaurant.
The PC industry wants to make touch functions more sophisticated and widespread. On-screen objects could be twisted and turned with several fingers, mimicking the action used in real life. The next version of Windows from Microsoft, Windows 7, will usher in a new era of touch technology when it appears on PCs later this year, according to Mr. Ben-David. Backed by Microsoft, Israel-based N-trig uses a combination of software and sensors to create a special type of computer screen that can interact with pens and fingers. N-trig’s technology works by pumping an electrical signal through the screen. When a finger hits the screen, the electricity is discharged. Software interprets that to move graphics on the screen. The company claims that its technology works better on the larger displays of laptops and PCs since it handles many inputs at once.
Working together, Microsoft and N-trig have created a type of software interface that lets other companies add touch functions to their programs. Such touch software can handle lots of fingers hitting a screen at once rather than just relying on one or two digits, as most of today’s touch screens do.
A touchscreen or touch screen is the assembly of both an input ("touch panel") and output ("display") device. The touch panel is normally layered on the top of an electronic visual display of an information processing system. The display is often an LCD, AMOLED or OLED display while the system is usually used in a laptop, tablet, or smartphone. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers.zooming to increase the text size.
The touchscreen enables the user to interact directly with what is displayed, rather than using a mouse, touchpad, or other such devices (other than a stylus, which is optional for most modern touchscreens).
Touchscreens are common in devices such as game consoles, personal computers, electronic voting machines, and point-of-sale (POS) systems. They can also be attached to computers or, as terminals, to networks. They play a prominent role in the design of digital appliances such as personal digital assistants (PDAs) and some e-readers. Touchscreens are also important in educational settings such as classrooms or on college campuses.
The popularity of smartphones, tablets, and many types of information appliances is driving the demand and acceptance of common touchscreens for portable and functional electronics. Touchscreens are found in the medical field, heavy industry, automated teller machines (ATMs), and kiosks such as museum displays or room automation, where keyboard and mouse systems do not allow a suitably intuitive, rapid, or accurate interaction by the user with the display"s content.
Historically, the touchscreen sensor and its accompanying controller-based firmware have been made available by a wide array of after-market system integrators, and not by display, chip, or motherboard manufacturers. Display manufacturers and chip manufacturers have acknowledged the trend toward acceptance of touchscreens as a user interface component and have begun to integrate touchscreens into the fundamental design of their products.
The prototypeCERNFrank Beck, a British electronics engineer, for the control room of CERN"s accelerator SPS (Super Proton Synchrotron). This was a further development of the self-capacitance screen (right), also developed by Stumpe at CERN
One predecessor of the modern touch screen includes stylus based systems. In 1946, a patent was filed by Philco Company for a stylus designed for sports telecasting which, when placed against an intermediate cathode ray tube display (CRT) would amplify and add to the original signal. Effectively, this was used for temporarily drawing arrows or circles onto a live television broadcast, as described in US 2487641A, Denk, William E, "Electronic pointer for television images", issued 1949-11-08. Later inventions built upon this system to free telewriting styli from their mechanical bindings. By transcribing what a user draws onto a computer, it could be saved for future use. See US 3089918A, Graham, Robert E, "Telewriting apparatus", issued 1963-05-14.
The first version of a touchscreen which operated independently of the light produced from the screen was patented by AT&T Corporation US 3016421A, Harmon, Leon D, "Electrographic transmitter", issued 1962-01-09. This touchscreen utilized a matrix of collimated lights shining orthogonally across the touch surface. When a beam is interrupted by a stylus, the photodetectors which no longer are receiving a signal can be used to determine where the interruption is. Later iterations of matrix based touchscreens built upon this by adding more emitters and detectors to improve resolution, pulsing emitters to improve optical signal to noise ratio, and a nonorthogonal matrix to remove shadow readings when using multi-touch.
The first finger driven touch screen was developed by Eric Johnson, of the Royal Radar Establishment located in Malvern, England, who described his work on capacitive touchscreens in a short article published in 1965Frank Beck and Bent Stumpe, engineers from CERN (European Organization for Nuclear Research), developed a transparent touchscreen in the early 1970s,In the mid-1960s, another precursor of touchscreens, an ultrasonic-curtain-based pointing device in front of a terminal display, had been developed by a team around Rainer Mallebrein[de] at Telefunken Konstanz for an air traffic control system.Einrichtung" ("touch input facility") for the SIG 50 terminal utilizing a conductively coated glass screen in front of the display.
In 1972, a group at the University of Illinois filed for a patent on an optical touchscreenMagnavox Plato IV Student Terminal and thousands were built for this purpose. These touchscreens had a crossed array of 16×16 infrared position sensors, each composed of an LED on one edge of the screen and a matched phototransistor on the other edge, all mounted in front of a monochrome plasma display panel. This arrangement could sense any fingertip-sized opaque object in close proximity to the screen. A similar touchscreen was used on the HP-150 starting in 1983. The HP 150 was one of the world"s earliest commercial touchscreen computers.infrared transmitters and receivers around the bezel of a 9-inch Sony cathode ray tube (CRT).
In 1977, an American company, Elographics – in partnership with Siemens – began work on developing a transparent implementation of an existing opaque touchpad technology, U.S. patent No. 3,911,215, October 7, 1975, which had been developed by Elographics" founder George Samuel Hurst.World"s Fair at Knoxville in 1982.
In 1984, Fujitsu released a touch pad for the Micro 16 to accommodate the complexity of kanji characters, which were stored as tiled graphics.Sega released the Terebi Oekaki, also known as the Sega Graphic Board, for the SG-1000 video game console and SC-3000 home computer. It consisted of a plastic pen and a plastic board with a transparent window where pen presses are detected. It was used primarily with a drawing software application.
Touch-sensitive control-display units (CDUs) were evaluated for commercial aircraft flight decks in the early 1980s. Initial research showed that a touch interface would reduce pilot workload as the crew could then select waypoints, functions and actions, rather than be "head down" typing latitudes, longitudes, and waypoint codes on a keyboard. An effective integration of this technology was aimed at helping flight crews maintain a high level of situational awareness of all major aspects of the vehicle operations including the flight path, the functioning of various aircraft systems, and moment-to-moment human interactions.
In the early 1980s, General Motors tasked its Delco Electronics division with a project aimed at replacing an automobile"s non-essential functions (i.e. other than throttle, transmission, braking, and steering) from mechanical or electro-mechanical systems with solid state alternatives wherever possible. The finished device was dubbed the ECC for "Electronic Control Center", a digital computer and software control system hardwired to various peripheral sensors, servos, solenoids, antenna and a monochrome CRT touchscreen that functioned both as display and sole method of input.stereo, fan, heater and air conditioner controls and displays, and was capable of providing very detailed and specific information about the vehicle"s cumulative and current operating status in real time. The ECC was standard equipment on the 1985–1989 Buick Riviera and later the 1988–1989 Buick Reatta, but was unpopular with consumers—partly due to the technophobia of some traditional Buick customers, but mostly because of costly technical problems suffered by the ECC"s touchscreen which would render climate control or stereo operation impossible.
Multi-touch technology began in 1982, when the University of Toronto"s Input Research Group developed the first human-input multi-touch system, using a frosted-glass panel with a camera placed behind the glass. In 1985, the University of Toronto group, including Bill Buxton, developed a multi-touch tablet that used capacitance rather than bulky camera-based optical sensing systems (see History of multi-touch).
The first commercially available graphical point-of-sale (POS) software was demonstrated on the 16-bit Atari 520ST color computer. It featured a color touchscreen widget-driven interface.COMDEX expo in 1986.
In 1987, Casio launched the Casio PB-1000 pocket computer with a touchscreen consisting of a 4×4 matrix, resulting in 16 touch areas in its small LCD graphic screen.
Touchscreens had a bad reputation of being imprecise until 1988. Most user-interface books would state that touchscreen selections were limited to targets larger than the average finger. At the time, selections were done in such a way that a target was selected as soon as the finger came over it, and the corresponding action was performed immediately. Errors were common, due to parallax or calibration problems, leading to user frustration. "Lift-off strategy"University of Maryland Human–Computer Interaction Lab (HCIL). As users touch the screen, feedback is provided as to what will be selected: users can adjust the position of the finger, and the action takes place only when the finger is lifted off the screen. This allowed the selection of small targets, down to a single pixel on a 640×480 Video Graphics Array (VGA) screen (a standard of that time).
Sears et al. (1990)human–computer interaction of the time, describing gestures such as rotating knobs, adjusting sliders, and swiping the screen to activate a switch (or a U-shaped gesture for a toggle switch). The HCIL team developed and studied small touchscreen keyboards (including a study that showed users could type at 25 wpm on a touchscreen keyboard), aiding their introduction on mobile devices. They also designed and implemented multi-touch gestures such as selecting a range of a line, connecting objects, and a "tap-click" gesture to select while maintaining location with another finger.
In 1990, HCIL demonstrated a touchscreen slider,lock screen patent litigation between Apple and other touchscreen mobile phone vendors (in relation to
An early attempt at a handheld game console with touchscreen controls was Sega"s intended successor to the Game Gear, though the device was ultimately shelved and never released due to the expensive cost of touchscreen technology in the early 1990s.
Touchscreens would not be popularly used for video games until the release of the Nintendo DS in 2004.Apple Watch being released with a force-sensitive display in April 2015.
In 2007, 93% of touchscreens shipped were resistive and only 4% were projected capacitance. In 2013, 3% of touchscreens shipped were resistive and 90% were projected capacitance.
A resistive touchscreen panel comprises several thin layers, the most important of which are two transparent electrically resistive layers facing each other with a thin gap between. The top layer (that which is touched) has a coating on the underside surface; just beneath it is a similar resistive layer on top of its substrate. One layer has conductive connections along its sides, the other along top and bottom. A voltage is applied to one layer and sensed by the other. When an object, such as a fingertip or stylus tip, presses down onto the outer surface, the two layers touch to become connected at that point.voltage dividers, one axis at a time. By rapidly switching between each layer, the position of pressure on the screen can be detected.
Resistive touch is used in restaurants, factories and hospitals due to its high tolerance for liquids and contaminants. A major benefit of resistive-touch technology is its low cost. Additionally, as only sufficient pressure is necessary for the touch to be sensed, they may be used with gloves on, or by using anything rigid as a finger substitute. Disadvantages include the need to press down, and a risk of damage by sharp objects. Resistive touchscreens also suffer from poorer contrast, due to having additional reflections (i.e. glare) from the layers of material placed over the screen.3DS family, and the Wii U GamePad.
Surface acoustic wave (SAW) technology uses ultrasonic waves that pass over the touchscreen panel. When the panel is touched, a portion of the wave is absorbed. The change in ultrasonic waves is processed by the controller to determine the position of the touch event. Surface acoustic wave touchscreen panels can be damaged by outside elements. Contaminants on the surface can also interfere with the functionality of the touchscreen.
The Casio TC500 Capacitive touch sensor watch from 1983, with angled light exposing the touch sensor pads and traces etched onto the top watch glass surface.
A capacitive touchscreen panel consists of an insulator, such as glass, coated with a transparent conductor, such as indium tin oxide (ITO).electrostatic field, measurable as a change in capacitance. Different technologies may be used to determine the location of the touch. The location is then sent to the controller for processing. Touchscreens that use silver instead of ITO exist, as ITO causes several environmental problems due to the use of indium.complementary metal-oxide-semiconductor (CMOS) application-specific integrated circuit (ASIC) chip, which in turn usually sends the signals to a CMOS digital signal processor (DSP) for processing.
Unlike a resistive touchscreen, some capacitive touchscreens cannot be used to detect a finger through electrically insulating ma
