non lcd monitors quotation

A monitor is key. You’ll use it hour after hour, day after day, year after year. Monitors even have the audacity to resist obsolescence, so the monitor you buy today might be the one you’re still using in a decade. (My editor and I both have decade-old Dell U2412 monitors that are still going strong.)

It’s an important decision, but not a difficult one, as there are dozens of great monitors to choose from. This guide will help you pick the best for your home office.

I’ve reviewed monitors and laptop displays for over a decade. While different monitors suit different owners, I believe the idealhome office monitor has a 27-inch screen and 4K resolution. It uses an IPS panel, reaches a brightness of at least 250 nits, and can display 99 percent of the sRGB color gamut. Around back you’ll find a USB-C port that can deliver enough power to charge a laptop, along with HDMI and DisplayPort, plus an ergonomic stand that can adjust for height and attaches to a VESA mount.

Finding a monitor that ticks most of these boxes won’t be too difficult. LG’s UltraFine line, Dell’s USB-C hub monitors, BenQ’s PD2720U and PD2725U, and HP’s U28 can check them all. Only the price may be higher than you hope; snagging any of the above will cost at least $450.

But like I said, different monitors suit different owners. These monitors are ideal for work, but they’re expensive. They also lack features you’ll crave when it’s time to clock out and fire up a round of Valorant. This guide will help you navigate the monitor world’s many caveats and find one that’s a fit for you.

Most standard-width monitors come in one of three sizes: 24-inch, 27-inch, and 32-inch. Bigger is not necessarily better. A large display may look more impressive, but I find it uncomfortable when placed close to my eyes. There are also practical considerations like perceived pixel density. A big monitor will look fuzzier than a smaller monitor of the same resolution unless you move it further away — which isn’t always an option.

That’s why a 27-inch monitor is my go-to recommendation. It’s large enough to look impressive on a typical home office desk but isn’t excessive. In my experience, 32-inch monitors should be reserved for unusually large and deep desks, or corner setups where it’s possible to position the display around four feet away from your face. This is especially true for 32-inch monitors with a resolution below 4K, which look grainy to me at a distance of three feet.

For the same reasons, 24-inch monitors work better if you have a small, slim desk (say, around 24 inches deep or less) or otherwise bring the monitor closer to your face. A 24-inch monitor may sound small, but it’ll look reasonably large because it’s so close. They’re also a great way to save money. You can buy a decent all-around monitor like the HP 24mh for less than $200. It won’t wow you, but it works in a pinch.

What about super-ultrawides, like the 49-inch Samsung Odyssey G9 series? These monitors can offer a commanding view and are a good alternative to a double or triple monitor setup but, like big ultrawides, you’ll need to build your setup around it.

4K resolution (3,840 x 2,160) looks fantastic and is widely available on 27-inch and 32-inch displays. It’s not that expensive, either. Budget 4K 27-inch monitors like the Dell S2721QS can get you 4K for $350 or less.

Twenty-four-inch monitors are a different story; 4K is rare, and 1440p is often the premium option. In fact, most monitors of this size are 1080p. It’s not ideal but it’s acceptable, as decreasing size increases pixel density. A 24-inch 1080p monitor is noticeably sharper than a 27-inch 1080p monitor.

Most monitors have HDMI and DisplayPort. There’s no great reason to prefer one over the other for remote work. The huge majority of monitors sold today offer both, so the port you use will likely come down to what’s available on your PC.

What about HDMI 2.1? It’s not necessary for remote work, and productivity monitors with HDMI 2.1 aren’t yet a thing. Be warned that HDMI 2.1 could get messy in 2022 due to the standard’s lax certification. It’s key only if you want to connect a PlayStation 5 or Xbox Series X game console.

If you’ve got extra cash to spend, the galaxy-brain move is to ignore HDMI and DisplayPort entirely and leap to USB-C and/or Thunderbolt. USB-C and Thunderbolt are great because they allow a single-cable solution for modern laptops that support the standard. You can plug in the laptop and charge it from the monitor while sending video to the monitor simultaneously. The best USB-C monitors even act as a hub with multiple extra ports like USB-A, USB-C, and ethernet.

But you’ll also need to make sure the monitor you buy provides enough electricity. Power Delivery currently maxes out at 100 watts, so even the most powerful monitors can’t fully power laptops like a top-spec Razer Blade or high-end MacBook Pro 16, but a monitor that delivers 60 watts or even 45 watts might be enough if you have a thin-and-light laptop like a Dell XPS 13 or MacBook Air. The higher the better, but if the USB-C monitor doesn’t deliver as much power as your laptop’s power brick, your battery might only charge when it’s idle or even powered off.

USB-C monitors are also expensive. The benefits often add several hundred dollars to the price when compared to an otherwise similar monitor that lacks USB-C. It’s worth the money, though: in 2019, I purchased a Viewsonic VG2455-2K for a sweet one-cable connection to USB-C capable laptops, and find it ideal for swiftly connecting my laptop to a larger screen.

Many monitors also adjust for tilt and swivel, and some pivot 90 degrees into portrait orientation. That can be particularly handy when a monitor is used as a second display. For example, you could swivel a monitor to directly face you while doing detailed work, like editing a photo, and swing it away when it’s just displaying Slack or Discord. Tilt is similar but on the vertical axis, and especially handy if you have a standing desk, as you may need to tilt the monitor up while the desk is standing.

But if your monitor doesn’t have enough range of motion, or you want to free up space on your desk, you could instead add a VESA-compatible monitor arm to get it off the ground. Look for monitors with a 100mm x 100mm VESA spacing pattern. This is an extremely common feature found in all but the most affordable monitors, and you only need to worry about the 100mm spacing pattern. Others exist, but are relevant to other types of displays (like televisions).

Larger, heavier monitors will need a beefier, more expensive arm: the model Ergotron recommends for the 49-inch Samsung Odyssey Neo G9 is currently $379 (and, at the time I wrote this, sold out!)

Color accuracy is critical to image quality. An inaccurate monitor will look unnatural, flat, and dull, with strange swings in quality depending on what you’re viewing and the precise colors that are inaccurate (it’s common for monitors to be less accurate in blue or cyan than other colors, for example). A monitor with terrible color will disappoint you every time you sit down to use it.

The good news? Accuracy is low-key the greatest advancement in monitors over the last decade. Noticeably inaccurate displays were common when I began testing monitors well over a decade ago. Today, most midrange monitors have reasonable accuracy straight out of the box.

Still, there is a difference between midrange and premium monitors. Those who want great color accuracy should look for a “factory calibrated” monitor, which typically includes a calibration report in the box. This doesn’t guarantee color accuracy is perfect, but it at least shows the company put the monitor through an extra layer of quality assurance. Also check reviewers to see if the monitor lives up to its claims.

Color gamut, which describes the spectrum of colors a monitor can display, is also good enough on most monitors. The majority of content on a computer targets a color gamut called sRGB. Modern monitors display at least 95 percent of this gamut, and many display it all. Other gamuts also exist. DCI-P3 is the most advertised, though you may see Rec.709 or Adobe RGB as well. These gamuts are important if your work requires them, though if that’s the case, I’m guessing you know that. As with color accuracy, buyers concerned about gamut should read reviews to verify a monitor lives up to its claims.

That’s not a big ask, but budget monitors can’t always manage it, so be careful if you’re shopping on a tight budget. Manufacturers also tend to choose a best-case scenario when quoting brightness, so the listed brightness may not always be available. Buy a monitor that promises a maximum brightness of at least 250 nits (aka cd/m2).

Nearly all monitors sold today use an LCD panel based on one of three technologies: twisted nematic (TN), in-plane switching (IPS), and vertical alignment (VA).

The least expensive monitors often use a TN panel. Avoid them. TN panel monitors will display an image, but that’s about it. They look achingly dull next to IPS and have astoundingly bad viewing angles.

A majority of monitors use IPS. Monitors based on IPS have very accurate color and can support a wide color gamut at a reasonable price. IPS struggles with dark scenes, however, because it can’t achieve a convincing shade of black. This is the dreaded “IPS glow” you may have heard of, which can look unappealing when watching movies or playing games. However, gamers still enjoy IPS monitors because some IPS panels have low response times and very high refresh rates.

What about VA? This panel type has the best contrast ratio and dark scene performance of the three, which makes VA a great go-to choice for entertainment and gaming. This is especially true of high-quality, modern VA panels, which have mostly solved the color accuracy and motion smearing issues of some past VA monitors.

The choice between IPS and VA has no clear answer, as both have their perks. When it comes to work, though, you may find the choice is made for you. A huge majority of productivity monitors use an IPS panel. VA is an option, but you’ll want to lean your search toward gaming monitors if you crave the high contrast a quality VA panel can provide.

High-refresh gaming displays aren’t especially expensive, with 24-inch, 144Hz models sold for as little as $200. But you’ll typically trade something away for refresh rate: that $200 monitor might use an iffy TN panel (rather than IPS or VA) or feature a low resolution. It’s possible to snag a 4K display for a reasonable sum, or one with a high refresh rate, but going for 4K at 144Hz means looking at monitors that cost as much as big televisions.

Also, USB-C with Power Delivery is rarely found in gaming monitors, and I haven’t seen a USB-C gaming monitor that doubles as a USB-C hub. That could be an issue if your work setup involves a lot of wired peripherals.

Neither of these are necessary for working from home, and you’ll likely have to spend thousands to snag a monitor with either tech. Alternatively, you could buy a television with Mini LED or OLED technology, but televisions still have their downsides as monitors.

If you demand the very best from a monitor, however, I recommend Mini LED. OLED’s burn-in worries are legitimate on the PC which, compared to a television, will display static images more frequently. Mini LED can’t match OLED’s contrast, but it’s still a major upgrade over a backlit LCD screen. There’s also the emerging category of quantum dot OLED (QD-OLED) screens, but manufacturers haven’t announced prices for those yet.

Computer monitors are an essential tool for both large corporations and small businesses. One or more high-quality monitors can help to optimize employee workflow and boost productivity. Whether you’re an employer or a working professional, order CTL computer monitors to access stunning displays and top-grade performance.

While all LED monitors are LCD monitors, the reverse isn’t true. There are LCD monitors that aren’t LED monitors. The difference between the two lies in the backlights. A typical LCD monitor uses fluorescent backlights to create the display, while LED monitors use light-emitting diodes. While the quality of each type of computer monitor depends on the particular product you’re looking at, LED monitors tend to have a higher-quality picture than LCD monitors.

Yes, CTL monitors can connect to Chromebooks. Connect your CTL computer monitor to your Chromebook by using the monitor’s HDMI, DisplayPort, DVI, or VGA port.

Unused electronics are the bane of the modern life. Perfectly functional gadgets sit quietly in a corner of the store room, doing nothing. If you"re wondering what to do with old computer monitors, here are a few easy ideas to repurpose unused screens.

Perhaps the best thing to do with an old flat-screen monitor is a DIY DAKboard. The DAKboard is a LCD wall display that shows the current time, weather forecast, calendar events, stock quotes, fitness data, and news headlines. It"s all displayed on a soothing photo. You could buy an official DAKboard, but the makers themselves have shown how to build your own wall display with a Raspberry Pi. when you can build one for far less money and a little geeky fun, the choice is obvious.

Basically, you will be cutting out the polarizing film of the old LCD monitor. This film will then be put on a simple pair of glasses. Now your screen appears white, but the glasses can "see" the content. It"s one of the best ways to keep prying eyes out of your PC.

If you have a broken old LCD monitor, it can be re-purposed into a usable mirror; but if you have a working old LCD monitor, adding a Raspberry Pi can turn it into a smart magic mirror!

If you"re on a tight budget for a first-time DIY project, consider the $100 smart mirror. It"s not the best version of turning an LCD monitor into a smart mirror, but you"ll get the basic features and not spend a bomb.

All desktop operating systems support the ability to use dual monitors. It"s pretty easy to setup dual monitors on Windows, and you can then customize how you use the two spaces. To connect two monitors, you will likely need a graphics card with multiple HDMI ports, or use an HDMI and a VGA port on desktops.

Like any gadget, monitors have a limited shelf life. If you"re looking to upgrade, you now have a few ideas of what to do with your old monitor. And that age should influence which project you chose. For example, given the effort involved in building a smart mirror, don"t go with a screen that"s already shown signs of trouble. The Raspberry Pi-based projects are usually the easiest to keep changing.

All-in-One refers to monitors with mini computer system embedded into the monitor. This allows for ease of use and space saving since an external computer is not needed but will raise the price of the monitor. Also, if an all-in-one is damaged and in needs replacing, it is more costly to replace an all-in-one than a stand-alone monitor or touch screen.

AG glass is added to protect the monitor’s LCD panel. When sunlight hits AG glass, the light energy is dispersed equally across the entire screen; these are no reflection “hot spots”. The AG coating results in a matte finish on the screen.

AR glass is added to protect the monitor’s LCD panel. When sunlight hits AR glass, the light energy is consolidated into a small but very bright reflected spot of light; the image on the rest of the screen stays in tact. By tilting or turning the monitor a few degrees, the operator can usually eliminate the bright spot entirely from his screen, and see clear start images even in direct bright sunlight.

The aspect ratio of a LCD display is the proportional relationship of its width compared to its height. The two numbers are commonly separated by a colon. The most common aspect ratios are 16:9 (aka widescreen) and 4:3 (closer to the shape of a square monitor, such as old CRT’s and TV’s). It is best to choose a monitor with the same aspect ratio as your video signal. You cannot customize a monitor’s native aspect ratio, so it is critical to know the aspect ratio of your incoming video signal beforehand.

Some monitors include built-in speakers that can play audio from your source. If a monitor does not have speakers built in, you may be able to run an aux cable from the audio output to an external speaker.

Auto re-start after power loss is a built-in feature, standard with all TRU-Vu monitors which ensures video is immediately displayed upon restoration of power following a power loss.

An automated ambient light sensor (sometimes shortened to ALS) on an LCD monitor allows for automatic brightness adjustment based on the environmental light surrounding the monitor. Ambient Light Sensors allow users to set brightness and timing ranges to control the intensity of these automatic adjustments. This means users have the ability to specify the maximum and minimum brightness levels the Ambient Light Sensor can adjust between. Additionally, you can specify how long you would like the sensor to wait before adjusting the brightness (between 1 and 60 seconds).

The bezel is the outside frame or edge that surrounds the monitor’s front glass or LCD panel. For aesthetics or hygiene, some people prefer frameless, Zero-Bezel monitors.

Luminance (AKA Brightness) is the measurement of how much light a monitor emits. The SI unit for luminance is Candela per Square Meter (Cd/m²). One Cd/m² is equal to one “nit,” a more common term with LCD monitors. The measure of nits a LCD display emits will be the main factor in determining the monitor’s perceived brightness. A monitor luminance of around 250-350 nits will work well indoors and most monitors fall in this range. 400-700 nits would be ideal for daylight use (Daylight Viewable monitors). 1,000 nits or more is required for viewing in direct, bright sunlight (Sunlight Readable monitors)

Color temperature is a way to describe light appearance provided by a video source or monitor. Color temperature is measured in Kelvin (K) and typically ranges from 2500K to 7500K. Higher Kelvin results in a cooler, bluer, daylight color temperature. Lower Kelvin results in a warmer, redder, candlelight color temperature. A balanced color temperature where the colors look natural for the scene is considered “white balanced.” This is when the color white looks like a true white without any other color present. NTSC, PAL, and now ATSC standards suggest video content on monitors to be displayed using 6500K. However, not all content adheres to this, so monitors may need to be tuned for the content to achieve white balance.

The control of a LCD monitor is usually accomplished through the OSD (On-Screen Display) via a small group of pushbuttons on the rear or front of the monitor, or via an IR remote that allow the user to access the monitor’s settings.

Display Colors is the number of colors the monitor can display. The higher, the better. These numbers are always shown in millions unless it is a dated monitor. Standard LCD monitors have 16.7 million colors, which equals 24-bit color. Color bits and display colors are directly related since display colors is based on the power of two. This is because 2 raised to the 24th power comes out to ~16.7 million.

The enclosure of a monitor is what surrounds the screen and all other components. Enclosures offer different looks, feels, and advantages and disadvantages. For example, most waterproof monitors will have 304 stainless steel or aluminum to avoid corrosion. Lightweight monitors will generally feature a ABS enclosure, a nylon-reinforced plastic for added durability. Powder-coated steel is another material used in many industrial-grade monitor solutions which offers increased protection and durability.

Hue is just another word for color; each position around the color wheel represents a different hue. For monitors, you can adjust the overall picture’s hue to give a look that is closer to the desired hue.

The humidity specification on the LCD monitor data sheets relate to relative humidity (RH) and is shown as a percentage. Relative Humidity measures water vapor, but relative to the temperature of the air. It measures the amount of actual water vapor in the air compared to the total amount of vapor that can occur at the current temperature. The same absolute humidity level but in two different climates will result in two different relative humidities. The relative humidity would be higher in the cooler climate, and lower in the warmer climate. The higher the percentage, the more humid it is relative to the temperature in the environment. At 100% relative humidity, the air is saturated and is at its dew point.

IR (Infrared) 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, and send the X and Y coordinates to the controller. IR touch screens generally feature larger screen sizes.

Isotropic Failure results when direct sunlight and high ambient temperatures combine to overheat the LCD screen. The screen will darken, or turn completely black. If the monitor’s internal temperature approaches 100°C (212°F) temperatures, the LCD panel will suffer irreparable harm. Please note that a monitor’s internal temperature may far exceed ambient temperatures when positioned in direct, bright sunlight. Therefore, the rated operating temperature of the LCD panel and the overall monitor must be sufficient to survive the worst-case heat scenarios that the monitor will be exposed to.

LCD stands for Liquid Crystal Display. The LCD panel directs the light from the backlight and produces the picture we see on the monitor’s screen. LCD panels use tiny liquid crystals to shift the light from one color to the next. The crystals are controlled using voltage from the monitor. Different LCD panels offer different advantages and can vary the overall cost of the monitor greatly.

LED Backlights are the most common backlights used in LCD flat panel displays today. The LED backlights are what illuminates the LCD panel. Without any backlights, an image could not be seen. A monitor’s life is based on the life of the backlights because they are so essential. LED backlights succeeded CCFL backlights and are more energy efficient, offer better contrast and brightness, and greater color range. LED backlights must be used with LCD panels to display an image.

Luminance (AKA Brightness) is the measurement of how much light a monitor emits. The SI unit for luminance is Candela per Square Meter (Cd/m²). One Cd/m² is equal to one “nit,” a more common term with LCD monitors. The measure of nits a LCD display emits will be the main factor in determining the monitor’s perceived brightness. A monitor luminance of around 250-350 nits will work well indoors and most monitors fall in this range. 400-700 nits would be ideal for daylight use (Daylight Viewable monitors). 1,000 nits or more is required for viewing in direct, bright sunlight (Sunlight Readable monitors)

Virtually all TRU-Vu monitors feature VESA mount holes on the rear of the monitor. VESA is an industry-standard hole pattern compatible with nearly any mounting solution on the market. The hole patterns are measured in millimeters, from center-to-center, for each of the 4 holes, in a square or rectangular pattern, such as 75 x 75mm, 100 x 100, 200 x 100, etc.

MTBF stands for Mean Time Between Failure. A monitor’s MTBF refers to the time period when the the monitor’s backlights will dim to 50% of the original brightness. MTBF is typically measured in hours. If the backlights of an LCD monitor with standard brightness levels dim to 50%, it is considered unusable because the screen is not bright enough for any use.

However, with Sunlight Readable monitors, things are different. If a Sunlight Readable monitor, which features at least 1,000 nits of brightness, dims down to 50% brightness, the monitor still has 500 nits of brightness. 500 nits of brightness is still twice the brightness of standard indoor monitors. Therefore, the Sunlight Readable monitor can be repurposed for use in other applications where it will not be subjected to direct sunlight.

The MVA panel is a type of LCD panel. MVA panels are newer than TN panels and offer wider viewing angles (typically 178° x 178°) This allows the monitor to be used in landscape or portrait mode, or mounted above eye level, with no loss of image quality.

Nits is the measurement of luminance. Nit is believed to come from the Latin word nitere, to shine. It is the measure of light emitter in a unit area and frequently used to specify the brightness of a display. Standard displays feature 200-300 nits, whereas Sunlight Readable Monitors range from 1,000 – 2,500 nits.

Open frame monitors are provided without typical enclosures. They are often used for limited-space applications, or when the display will be integrated into a machine or system. Open frame monitors and touch screens are available in two configurations: all components are mounted to the rear of the LC panel, or in a “kit” version, the LCD panel and all other components are provided loose, enabling the end user to mount them in any way they desire.

The operating temperature of the LCD video display is the range of temperature that is deemed acceptable for using the monitor. Operating outside the high end of this range can result in isotropic failure, or the components can begin to fail at temperatures below the low end of the range. The storage temperature of a monitor will always be equal to or greater than the operating temperature since monitors generate heat when operated.

Adding glass over a LCD panel does protect it. However, this also causes increased internal reflections, both from external light as well as from the LCD’s own backlights, thereby reducing image quality. It also creates an air gap between the glass and the panel.

Optical Bonding is the process of injecting an optical-grade resin into the gap between the LCD panel and the glass. This eliminates internal reflections, eliminates the possibility of internal condensation, increases the contrast ratio, and improves the image quality.

Landscape orientated monitors are long like a sprawling landscape — they stretch left to right. Landscape oriented monitors are the most common for viewing since it is the industry standard for almost all media, from film to broadcast TV.

It is important to know your end goal with orientation. For example, sunlight readable monitors have polarization filters specified to the monitor’s native orientation. If you flip the orientation of the signal, you may also need to flip the polarizing filters if being viewed by someone wearing polarized sunglasses.

Overscan is when part of the video signal is outside the visible bounds of the screen. This occurs when the input video signal has a larger resolution than the monitor’s maximum resolution. Thankfully, this is not much of an issue any more with added standards (title and action safe) and expanded compatibility with signals and monitors. CRTs from the 1930s to the early 2000s were highly variable when it came to how the image was positioned within the border of the screen, resulting in overscan issues.

Pixel pitch (AKA Dot Pitch) is the distance from one pixel’s center to the adjacent pixel’s center. Pixel pitch is measured in millimeters (mm) and most LCD monitors range from 0.10mm to 0.70mm. Pixel pitch is directly correlated to resolution and viewing distance. The smaller the pixel pitch, the more condensed the pixels are, and the higher the resolution. However, a smaller pixel pitch requires a closer viewing distance. The viewing distance should decide the ideal pixel pitch for you.

Polarizing filters are made from a type of transparent crystal, which allow certain light waves to pass through. A vertical allows vertical light waves, and blocks horizontal light waves, and vice versa. LCD monitors use two polarizers to control the brightness of the light. Care must be taken to choose the proper polarizers. For example, Incorrect polarizers used in Sunlight Readable monitors would result in the monitors appearing invisible to anyone wearing polarized sunglasses.

Powder coated steel is one of the most common materials used to build rugged equipment such as industrial-grade monitors, so long as the monitor will not be subjected to contact with liquids. The coating is applied electrostatically and then cured under heat. It provides a harder, tougher finish than conventional paint.

Monitors have either internal or external power supplies. Monitors with internal power supplies have a AC power cord which plugs into a wall outlet. The incoming 120VAC power is then converted down to 12 or 24VDC inside the monitor. External power supplies are generally small, black rectangular devices which converts AC power to DC. They have two cords; one plugs into a wall outlet, and the other cord carries 12 or 24VDC to the monitor.

Private labelling is when one company manufactures a product that will be sold under another company’s brand. TRU-Vu private labels a great number of monitors and touch screens, featuring the client’s name, model number and logo on the front bezel and rear label.

Protective glass is when an extra layer of glass is added onto the front of the LCD screen. The primary reason to place glass over the LCD panel is to protect the panel from damaged. AR (Anti-Reflective) or AG (Anti-Glare) glass will help to reduce unwanted reflections and glare.

Rack mount is a type of enclosure that features flanges on the left and right sides suitable for mounting directly into a standard 19” rack with the face of the LCD monitor visible at all times. The height of the unit is measured in rack units (RU) where 8U and 9U are most common to fit 17-inch or 19-inch LCDs.

The refresh rate refers to the number of times a monitor can show a static image per second. Hertz (Hz) is the unit used to measure the refresh rate of a monitor. This is similar to frame rate. Frame rate refers to the content itself, whereas refresh rate refers to the display showing the content. Too low of a refresh rate on a monitor with high frame rate content will result in excessive motion blur. Almost all monitors built for use in North America feature a 60Hz refresh rate. However some gaming monitors can feature refresh rates of 144Hz or higher.

Response time is how quickly the monitor will react to a signal. Response time is measured in milliseconds (ms) and most monitors today have response times of 10 ms and lower. A smaller response time is better than larger because it means the monitor responds quicker. Too long of a response time will result in streaks or “ghosts” from fast moving objects.

The display resolution of a LCD monitor is the number of horizontal pixels multiplied by the number of vertical pixels. TRU-Vu’s display resolutions range from 640 x 480 up to 3840 x 2160 (aka 4K resolution). Larger display sizes will typically require higher resolutions that provide sharp image quality. However, LCD displays with smaller screen sizes can have lower pixel resolutions but still produce excellent image quality.

RGB stands for Red Green Blue. It is the color model used in sensing, representing, and displaying images in electronic systems like monitors and computers. RGB is an additive color model that adds the 3 primary colors (red, green, and blue) together to reproduce a an array of colors. Red, green, and blue together will result in white. LCD monitors will use RGB sub-pixels to create different colored pixels in order to represent a larger picture.

Saturation in monitors or colors refers to the intensity of a color. Lower saturation will feature washed out colors with less pigment. Higher saturation will feature bright colors that are intensely colored.

SAW (Surface Acoustic Wave) is a touch screen technology. SAW touch screens utilize a series of piezoelectric transducers and receivers 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.

The serial port is a serial communication interface where information is transferred in or out sequentially one bit at a time. The term serial port usually identifies hardware compliant to the RS-232 standard or similar. RS-232 is another common connection used to transmit data. For monitors, RS-232 can be used to power a touchscreen and communicate recorded touches to a connected computer.

The screen size of an LCD monitor is determined by measuring from one corner of the LCD screen (excluding the bezel) diagonally to the opposite corner of the LCD screen. Screen size is measured in inches. Screen size is not to be confused with Viewable Area, as the viewable area is the horizontal measurement multiplied by the vertical measurement of the LCD Screen.

Sunlight Readable monitors are able to show content in indirect or direct sunlight without loss in image quality thanks to a higher brightness. Monitor brightness is measured in nits. Typical indoor monitors range from 200-300 nits. Indirect Sunlight or Daylight Readable monitors feature 400-700 nits. Direct Sunlight Readable monitors feature 1,000-2,500 nits. This much higher brightness is what allows Sunlight Readable monitors to be viewed in sunlight.

Surface capacitive touch screen monitors have a transparent electrode layer placed on top of a glass panel, and 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 exact touch point. Surface capacitive touch screens can only be activated by the touch of human skin or a stylus holding an electrical charge. It will not activate with a gloved finger, or other objects.

The TN panel is a type of LCD panel; TN stands for twisted nematic and is one of the most widely used, cost effective, but oldest LCD panels available. The viewing angles are not as good as other types of panels, and are generally worn when viewing the monitor from below. However, the response time is one of the quickest out of all LCD panels.

Other technologies allow for multitouch functions such as pinch-to-zoom, but cannot work with operators wearing thick gloves. The type of touch screen technology you select will be contingent upon many factors, including type of data to be displayed (video, graphics, text), the intended users, the operating environment and where/how it will be mounted. Chosen correctly, touch screen monitors will be an excellent addition to your system. Please see our touch screen guide for further details.

USB stands for Universal Serial Bus. It is one of the most common industry standard data connections used today. USB cables allow communication and power supply between computers, peripherals, and other computers. For monitors, USB can be used to power a touchscreen and communicate recorded touches to a connected computer.

The viewable area of a video display is the actual width of the LCD screen (typically in inches) x by the height of the LCD screen in inches (excluding the enclosure). This measures the total area of the screen and shows how wide and tall the screen will be. Monitors with the same Screen Size will have the same Viewable Area and visa versa.

The viewing angle of a monitor is the maximum angle the monitor can be viewed at before image quality degrades. Viewing angles are measured in horizontal and vertical degrees. When the monitor is in a position where viewing occurs outside of this maximum angle, the brightness and contrast ratio will begin to drop. At a severe enough angle, the perceived colors on screen will begin to shift. Make sure your monitor’s end position will allow viewing within these angles for ideal results. The worst viewing angle for most LCD panels is usually from the bottom looking upward at the panel. A MVA-type panel will provide full 178° x 178° viewing angles.

The warranty offered with a monitor is how long the monitor “shall be free from defects in materials and workmanship from the date of shipment.” Some monitors will have longer or shorter warranties depending on the product specifics. Nearly all TRU-Vu Monitors carry a 3-year warranty.

Waterproof means a device is completely sealed from the ingress of water under specified conditions. The waterproofed device will remain unaffected by water. IP ratings and NEMA standards measure waterproofing based on specified conditions. We have a full line of waterproof monitors and touch screens.

Zero Bezel or Bezel-Less enclosures are monitors which have no bezel, frame, or edge around the front edges. If you run your finger across the monitor’s front face, you would never feel a bump on the edges. Zero Bezel or Bezel-Less monitors are more stylish and hygienic. They are far superior medical displays, as the bezels found on standard LCD monitors often able germs and debris to collect near and under the bezel.

First, we will provide a brief technical overview of functional principles as they relate to visual stimulus presentation. Detailed descriptions and parameter measurements are already available from the existing literature; however, our intention here is to equip readers with limited technical expertise with the necessary knowledge to set up computer experiments with LCD monitors. Thus, we keep our explanations relatively short and simplified.

LCD monitors work differently: Each pixel consists of liquid crystal threads that can be twisted or arranged in parallel by an electrical current applied to them. This leads to a polarization effect that either allows or prevents light passing through. A white light source located behind this crystal array uniformly and constantly illuminates the array. To display a black pixel, the crystal threads are twisted by 90° such that no light will pass through. A white pixel is achieved by aligning the crystals such that maximum light is allowed to pass through, until a different, non-white color needs to be displayed (see the lower panel of Fig. 1 for an LCD pixel’s brightness over time). This is a static process, not a pulsed one as in CRTs.

In theory, the difference in presentation methods, namely a strobing versus a static image, should be of no consequence if the light energy that falls onto the retina remains the same over the time period of one single frame. As the Talbot-Plateau law states2 is equally well detectable as a light flash presented for 60 ms at 40 cd/m2. This suggests that temporal integration can be easily described by energy summation”. Thus, in principle, LCD and CRT monitors should be able to yield comparable results.

However, due to the differences in technology, the visual signals produced by the two display types have different shapes (i.e., a different light energy-over-time-curve; see Fig. 1). Moreover, default luminance as well as visual-signal response times (in addition to other parameters, see below) differ between most CRT and LCD monitors

Table 1 reports the parameters we considered in setting up the CRT and LCD monitors. Certainly, most of them are commonly considered when setting up a computer experiment; nevertheless we deemed it important to mention them here explicitly, as their neglect might have unintended consequences. We used a 17” Fujitsu Siemens Scenicview P796-2 CRT color monitor previously used in several published studies including studies with masked presentation conditions

Our measurements revealed several interesting characteristics: First, luminance of the LCD monitor at default setting (i.e., maximum brightness) exceeded the CRT luminance at a ratio of 3.25:1. However, comparable average luminance can be (and was) achieved by downregulating the LCD monitor (the older CRT technology emits less energy even at maximum settings, see Table 2), without participants perceiving it as unnaturally dark. If one plans to upgrade from CRT to LCD monitors in an experimental laboratory, we therefore recommend measuring the CRT monitors’ brightness levels and matching them in the new LCD monitors’ user setup, if comparability with the old setup is needed. This will minimize hardware-dependent variability, thus contributing to better replicability. Please note that a brightness adaption is not a necessary precondition when employing LCD monitors; researchers should simply be aware that the brightness level can have an influence onto the resulting effects, especially in time-critical experiments with short and/or masked presentation. Thus, we recommend the adaptation for time-critical experiments in which researchers orient on existing empirical evidence gathered with CRT monitors. Furthermore, gray-to-gray response times varied slightly depending on the employed brightness levels2), so we suggest that researchers can rely on this more efficient method as an approximation.

For the empirical comparison of human performance with CRT and LCD monitors, we relied on these results and set the monitor settings accordingly (see Method section below).

Participants were administered a masked number priming task and a subsequent forced-choice prime discrimination task using both a CRT and an LCD monitor. In this well-established paradigm

Of central interest was the question whether both monitors would yield comparable masked priming effects. Monitors were set according to the parameters described in the previous section (see also Method section below). In order to obtain conclusive evidence, we decided for sequential hypothesis testing using Bayes factorshttps://osf.io/g842s/.

The display in modern monitors is typically an LCD with LED backlight, having by the 2010s replaced CCFL backlit LCDs. Before the mid-2000s,CRT. Monitors are connected to the computer via DisplayPort, HDMI, USB-C, DVI, VGA, or other proprietary connectors and signals.

Originally, computer monitors were used for data processing while television sets were used for video. From the 1980s onward, computers (and their monitors) have been used for both data processing and video, while televisions have implemented some computer functionality. In the 2000s, the typical display aspect ratio of both televisions and computer monitors has changed from 4:3 to 16:9.

Modern computer monitors are mostly interchangeable with television sets and vice versa. As most computer monitors do not include integrated speakers, TV tuners, nor remote controls, external components such as a DTA box may be needed to use a computer monitor as a TV set.

Early electronic computer front panels were fitted with an array of light bulbs where the state of each particular bulb would indicate the on/off state of a particular register bit inside the computer. This allowed the engineers operating the computer to monitor the internal state of the machine, so this panel of lights came to be known as the "monitor". As early monitors were only capable of displaying a very limited amount of information and were very transient, they were rarely considered for program output. Instead, a line printer was the primary output device, while the monitor was limited to keeping track of the program"s operation.

Multiple technologies have been used for computer monitors. Until the 21st century most used cathode-ray tubes but they have largely been superseded by LCD monitors.

The first computer monitors used cathode-ray tubes (CRTs). Prior to the advent of home computers in the late 1970s, it was common for a video display terminal (VDT) using a CRT to be physically integrated with a keyboard and other components of the workstation in a single large chassis, typically limiting them to emulation of a paper teletypewriter, thus the early epithet of "glass TTY". The display was monochromatic and far less sharp and detailed than on a modern monitor, necessitating the use of relatively large text and severely limiting the amount of information that could be displayed at one time. High-resolution CRT displays were developed for specialized military, industrial and scientific applications but they were far too costly for general use; wider commercial use became possible after the release of a slow, but affordable Tektronix 4010 terminal in 1972.

By the end of the 1980s color progressive scan CRT monitors were widely available and increasingly affordable, while the sharpest prosumer monitors could clearly display high-definition video, against the backdrop of efforts at HDTV standardization from the 1970s to the 1980s failing continuously, leaving consumer SDTVs to stagnate increasingly far behind the capabilities of computer CRT monitors well into the 2000s. During the following decade, maximum display resolutions gradually increased and prices continued to fall as CRT technology remained dominant in the PC monitor market into the new millennium, partly because it remained cheaper to produce.

There are multiple technologies that have been used to implement liquid-crystal displays (LCD). Throughout the 1990s, the primary use of LCD technology as computer monitors was in laptops where the lower power consumption, lighter weight, and smaller physical size of LCDs justified the higher price versus a CRT. Commonly, the same laptop would be offered with an assortment of display options at increasing price points: (active or passive) monochrome, passive color, or active matrix color (TFT). As volume and manufacturing capability have improved, the monochrome and passive color technologies were dropped from most product lines.

The first standalone LCDs appeared in the mid-1990s selling for high prices. As prices declined they became more popular, and by 1997 were competing with CRT monitors. Among the first desktop LCD computer monitors was the Eizo FlexScan L66 in the mid-1990s, the SGI 1600SW, Apple Studio Display and the ViewSonic VP140vision science remain dependent on CRTs, the best LCD monitors having achieved moderate temporal accuracy, and so can be used only if their poor spatial accuracy is unimportant.

High dynamic range (HDR)television series, motion pictures and video games transitioning to widescreen, which makes squarer monitors unsuited to display them correctly.

Organic light-emitting diode (OLED) monitors provide most of the benefits of both LCD and CRT monitors with few of their drawbacks, though much like plasma panels or very early CRTs they suffer from burn-in, and remain very expensive.

Radius of curvature (for curved monitors) - is the radius that a circle would have if it had the same curvature as the display. This value is typically given in millimeters, but expressed with the letter "R" instead of a unit (for example, a display with "3800R curvature" has a 3800mm radius of curvature.

Dot pitch represents the distance between the primary elements of the display, typically averaged across it in nonuniform displays. A related unit is pixel pitch, In LCDs, pixel pitch is the distance between the center of two adjacent pixels. In CRTs, pixel pitch is defined as the distance between subpixels of the same color. Dot pitch is the reciprocal of pixel density.

Pixel density is a measure of how densely packed the pixels on a display are. In LCDs, pixel density is the number of pixels in one linear unit along the display, typically measured in pixels per inch (px/in or ppi).

Contrast ratio is the ratio of the luminosity of the brightest color (white) to that of the darkest color (black) that the monitor is capable of producing simultaneously. For example, a ratio of 20,000∶1 means that the brightest shade (white) is 20,000 times brighter than its darkest shade (black). Dynamic contrast ratio is measured with the LCD backlight turned off. ANSI contrast is with both black and white simultaneously adjacent onscreen.

Color depth - measured in bits per primary color or bits for all colors. Those with 10bpc (bits per channel) or more can display more shades of color (approximately 1 billion shades) than traditional 8bpc monitors (approximately 16.8 million shades or colors), and can do so more precisely without having to resort to dithering.

Refresh rate is (in CRTs) the number of times in a second that the display is illuminated (the number of times a second a raster scan is completed). In LCDs it is the number of times the image can be changed per second, expressed in hertz (Hz). Determines the maximum number of frames per second (FPS) a monitor is capable of showing. Maximum refresh rate is limited by response time.

On two-dimensional display devices such as computer monitors the display size or view able image size is the actual amount of screen space that is available to display a picture, video or working space, without obstruction from the bezel or other aspects of the unit"s design. The main measurements for display devices are: width, height, total area and the diagonal.

With the introduction of flat panel technology, the diagonal measurement became the actual diagonal of the visible display. This meant that an eighteen-inch LCD had a larger viewable area than an eighteen-inch cathode-ray tube.

Until about 2003, most computer monitors had a 4:3 aspect ratio and some had 5:4. Between 2003 and 2006, monitors with 16:9 and mostly 16:10 (8:5) aspect ratios became commonly available, first in laptops and later also in standalone monitors. Reasons for this transition included productive uses (i.e. besides Field of view in video games and movie viewing) such as the word processor display of two standard letter pages side by side, as well as CAD displays of large-size drawings and application menus at the same time.LCD monitors and the same year 16:10 was the mainstream standard for laptops and notebook computers.

In 2011, non-widescreen displays with 4:3 aspect ratios were only being manufactured in small quantities. According to Samsung, this was because the "Demand for the old "Square monitors" has decreased rapidly over the last couple of years," and "I predict that by the end of 2011, production on all 4:3 or similar panels will be halted due to a lack of demand."

The resolution for computer monitors has increased over time. From 280 × 192 during the late 1970s, to 1024 × 768 during the late 1990s. Since 2009, the most commonly sold resolution for computer monitors is 1920 × 1080, shared with the 1080p of HDTV.2560 × 1600 at 30 in (76 cm), excluding niche professional monitors. By 2015 most major display manufacturers had released 3840 × 2160 (4K UHD) displays, and the first 7680 × 4320 (8K) monitors had begun shipping.

Most modern monitors will switch to a power-saving mode if no video-input signal is received. This allows modern operating systems to turn off a monitor after a specified period of inactivity. This also extends the monitor"s service life. Some monitors will also switch themselves off after a time period on standby.

Most modern monitors have two different indicator light colors wherein if video-input signal was detected, the indicator light is green and when the monitor is in power-saving mode, the screen is black and the indicator light is orange. Some monitors have different indicator light colors and some monitors have blinking indicator light when in power-saving mode.

Many monitors have other accessories (or connections for them) integrated. This places standard ports within easy reach and eliminates the need for another separate hub, camera, microphone, or set of speakers. These monitors have advanced microprocessors which contain codec information, Windows interface drivers and other small software which help in proper functioning of these functions.

Monitors that feature an aspect ratio greater than 2:1 (for instance, 21:9 or 32:9, as opposed to the more common 16:9, which resolves to 1.77:1).Monitors with an aspect ratio greater than 3:1 are marketed as super ultrawide monitors. These are typically massive curved screens intended to replace a multi-monitor deployment.

These monitors use touching of the screen as an input method. Items can be selected or moved with a finger, and finger gestures may be used to convey commands. The screen will need frequent cleaning due to image degradation from fingerprints.

Some displays, especially newer flat panel monitors, replace the traditional anti-glare matte finish with a glossy one. This increases color saturation and sharpness but reflections from lights and windows are more visible. Anti-reflective coatings are sometimes applied to help reduce reflections, although this only partly mitigates the problem.

Most often using nominally flat-panel display technology such as LCD or OLED, a concave rather than convex curve is imparted, reducing geometric distortion, especially in extremely large and wide seamless desktop monitors intended for close viewing range.

Newer monitors are able to display a different image for each eye, often with the help of special glasses and polarizers, giving the perception of depth. An autostereoscopic screen can generate 3D images without headgear.

Raw monitors are raw framed LCD monitors, to install a monitor on a not so common place, ie, on the car door or you need it in the trunk. It is usually paired with a power adapter to have a versatile monitor for home or commercial use.

A stowable rack mount monitor is 1U, 2U or 3U high and is mounted on rack slides allowing the display to be folded down and the unit slid into the rack for storage as a drawer. The flat display is visible only when pulled out of the rack and deployed. These units may include only a display or may be equipped with a keyboard creating a KVM (Keyboard Video Monitor). Most common are systems with a single LCD but there are systems providing two or three displays in a single rack mount system.

An open frame monitor provides the display and enough supporting structure to hold associated electronics and to minimally support the display. Provision will be made for attaching the unit to some external structure for support and protection. Open frame monitors are intended to be built into some other piece of equipment providing its own case. An arcade video game would be a good example with the display mounted inside the cabinet. There is usually an open frame display inside all end-use displays with the end-use display simply providing an attractive protective enclosure. Some rack mount monitor manufacturers will purchase desktop displays, take them apart, and discard the outer plastic parts, keeping the inner open-frame display for inclusion into their product.

Van Eck phreaking is the process of remotely displaying the contents of a CRT or LCD by detecting its electromagnetic emissions. It is named after Dutch computer researcher Wim van Eck, who in 1985 published the first paper on it, including proof of concept. Phreaking more generally is the process of exploiting telephone networks.

Unlike CRT monitors, LCD monitors display information well at only the resolution they are designed for, which is known as the native resolution. Digital displays address each individual pixel using a fixed matrix of horizontal and vertical dots. If you change the resolution settings, the LCD scales the image and the quality suffers. Native resolutions are typically:

When you look at an LCD monitor from an angle, the image can look dimmer or even disappear. Colors can also be misrepresented. To compensate for this problem, LCD monitor makers have designed wider viewing angles. (Do not confuse this with a widescreen display, which means the display is physically wider.) Manufacturers give a measure of viewing angle in degrees (a greater number of degrees is better). In general, look for between 120 and 170 degrees. Because manufacturers measure viewing angles differently, the best way to evaluate it is to test the display yourself. Check the angle from the top and bottom
