number of display screens connected pricelist

By now, a dual-monitor setup has become commonplace. Multitasking on a single screen is just way too confining. But why stop at two displays? I can speak from experience: Having multiple monitors (and I’m talking three, four, five, or even six) is just…awesome, and something you totally need in your life.

Right now, my main PC has a triple-monitor setup: my main 27-inch central monitor, with a 24-inch monitor on either side. I use my extra monitors for a number of things, such as comparing spreadsheets side-by-side, writing articles while also doing research, keeping tabs on my social media feeds, and, of course, watching Netflix.

Using one of your monitors in vertical orientation can make a big difference for scrolling long documents. If you’re a gamer, well, surely you can see how great three-plus monitors can be for games that support multi-monitor setups. You can even use your TV as an extra computer monitor!

Before you run out and buy a bunch of extra monitors, check to see whether your computer is physically capable of handling all that graphics prowess. First, look at the back of your PC: How many graphics ports (DVI, HDMI, DisplayPort, and VGA) do you see?

Just because you see three or more ports on your discrete graphics card, however, doesn’t necessarily mean you can use all of them at the same time. For example, many older Nvidia cards are unable to run more than two monitors on a single card, even if they have more than two ports. The best way to find out whether your graphics card supports multiple monitors is to find the name of your card (Control Panel > Device Manager > Display Adapters) and Google it with the monitor setup you’re looking to run (e.g. “Nvidia GTX 1660 four monitors”).

If your graphics card supports—and has enough ports for—the number of monitors you want to set up, excellent. If not, you may need to purchase an additional graphics card to get the multi-monitor support you’re looking for.

If you buy a graphics card solely for the purpose of having multiple monitors, it’s best to get a cheaper modern option, as current GPUs can power several displays without issue. Check out the best budget graphics card section of our GPU guide for your best options.

Alternatively, monitors with DisplayPort multi-streaming support can be daisy-chained together from a single DisplayPort connection on your graphics card, using additional DisplayPort cables to connect the additional monitors to one another. The various displays don’t even need to be the same size or resolution. ViewSonic’s VP2468 is one such example. At around $330 on Amazon, this 24-inch monitor is on the pricier side, but in addition to DisplayPort-out, it also offers a premium IPS screen, and a super-thin bezel, which is ideal for multi-monitor setups.

Once you figure out your graphics card situation, it’s time for the fun part: obtaining extra monitors. In general, monitors can be had for fairly cheap these days. Assuming you can’t finagle a hand-me-down, a 24-inch monitor with an IPS screen will run you around $150, such as the Acer R240HY. You can get a 24-inch TN screen, which will likely trade strong off-axis viewing for a lower response time—something gamers might prefer—for roughly the same money, such as the Asus VS248H-P ($160 on Amazon). You can also find smaller IPS monitors at around 21.5 inches, such with this HP Pavilion IPS display, for.

Of course, the perfect monitor for you depends on multiple factors, including the monitors you already have, the size of your desk, and what you’re planning on using your extra monitor for. (Of course, resolution is yet another variable, and you can see our article about 1080p vs. 4K monitors to help you make a decision in that area as well.)

In my case, I already had two 24-inch monitors, and I wanted a larger monitor as the centerpiece of my setup, so I picked up a 27-inch monitor and placed it between my two 24-inch displays. I’m not using my multi-monitor setup to play multi-monitor games, so the difference in sizes (and the difference in heights—my 27-inch monitor’s stand holds that monitor about one inch higher than my 24-inchers) isn’t an issue for me. However, if you’re planning on doing a lot of gaming or watching videos that span multiple monitors, this height difference will make for a not-so-seamless experience.

Before you buy your monitors, you’ll also want to make sure they have input ports that correspond with your PC’s output ports. While you could use conversion cables, such as DVI-to-HDMI or DisplayPort-to-DVI, they can be a hassle. If you have a VGA port on your PC or your monitor, I suggest staying away from it: VGA is an analog connector, which means your picture will be noticeably less sharp and colors will be less vivid.

The first thing you’ll want to do is configure Windows to play nicely with your multiple monitors. If you’re running Windows 7 or Windows 8, right-click on the desktop and click Screen resolution;in Windows 10, click Display settings. This will take you to a screen where you can configure the options you have for multiple monitors in Windows.

Here, you can confirm that all your monitors are detected. Click Identify, which will cause a large number to appear on each of your displays, so you can determine which screen is which. Select the monitor you’d like to serve as your main display (which will also determine where your taskbar and Start button appears). A drop-down menu lets you choose whether to duplicate your desktop or extend your desktop across all the screens. In most multi-monitor setups, you’ll want to extend your desktop across all three (or four, or whatever) of your displays.

Alternately, you can set up your multi-monitor configuration in your GPU’s control panel. Right-click your desktop and choose either the Nvidia or AMD control panel (depending on your graphics card), and find the Display section, which will offer similar options as Windows.

Gaming on several displays at once requires far more graphical firepower than gaming on a single screen alone, because the GPU has so many more pixels to push—so if you’re not running a sufficiently robust graphics card or cards, you’ll almost certainly see lag and artifacting in your multi-monitor games. Once again, check out PCWorld’s guide for choosing the best graphics card for gaming.

You’ll also need to go into your game—not all games are multi-monitor compatible—and configure the video or display settings to the correct resolution so that the game spans across all of your monitors instead of staying squished on just one. You’ll also want to play around with other settings as the game allows, including field of view (too low, and there will be too much going on around you; too high and everything on your left and right screens will be hugely distorted).

For gaming, it’s easier if you have multiple identical displays, because otherwise you’ll run into issues with resolution, distortion (if your displays aren’t at the same height), and color calibration, all of which can be difficult to work with if you’re trying to play in a “seamless” environment.

If working with multiple displays seems like more trouble than you want to bother with for gaming, maybe you’d be better off with a single ultrawide monitor. Check out our article on the pros and cons of dual displays versus a single ultrawide.

You use it for work. You use it for gaming. You use it to access Netflix, YouTube, and your ex’s HBO account. It’s your computer monitor, and opting for a model that fits you and your needs is crucial. Whether your old display has died or you’ve decided that you need to upgrade to take advantage of the latest software, buying a new monitor is a big decision.

Not everyone is looking for the same thing, however. Some buyers are looking for a great display, while others put features and connectivity at the forefront. With so many great options out there, it’s easy to get confused, which is why we’ve put together the convenient buying guide below.

How big is big enough? When it comes to computer monitors, you want something that can fit comfortably on your desk while giving you plenty of screen real estate. While in the past sub-20-inch monitors were commonplace, today, unless you’re really constrained for space, there’s no real need to buy anything under 22 inches. For most, 24 inches is going to be a baseline, as you can pick up a number of screens at that size for around $100, and they look fantastic at 1080p.

For those who want more than that, though, there are plenty of sizes to choose from. Monitors that stretch 27 inches diagonally are increasingly popular, and there are plenty of options beyond 30 inches that are affordable. If you want to go extreme, we’ve even tried some great computer monitors that get close to 50 inches, like Samsung’s CHG90.

While you’ll need to sit well back from those, there’s no denying that they look amazing. They give you the same screen as multiple smaller monitors without a bezel dividing them down the middle. They tend to be rather expensive, though, and if you go really wide, you’ll struggle to find media that can display at close to its native resolution, leaving the picture to either look stretched or surrounded by black.

Anywhere between 24 and 30 inches is going to be perfectly fine for most users. They let you make the most of modern resolutions and color clarity, and they also fit a couple of different web pages open at the same time without needing to use two monitors, which is handy for many professionals. They don’t tend to be too expensive at that size, either, unless you opt for the top-end models.

Today, all the best screens are still LCD monitors that use LED technology for a slim product that saves energy while providing ideal backlighting. We’ve been waiting years for OLED technology to make the transition to PC monitors, it isfinally beginning thanks to brands like LG, but the technology is still relatively rare.

One aspect of PC monitors that you do need to consider, though, is resolution. While 1080p was once the gold standard, today, it’s just the baseline. If you’re happy to spend a little more, there are a few other options worth considering, especially if you want to improve screen space or gaming visuals. Resolution isn’t the be-all and end-all of monitor features, though. In fact, too much resolution on too small of a screen can often be annoying because it shrinks all images down and forces you to enlarge everything to easily read it.

1080p: If you want reasonable clarity, but want to save on cost or focus on other, more important features, 1080p is where it’s at — as long as the monitor you’re buying isn’t extremely large. 1080p is ideal for 21-inch to 24-inch displays. These monitors offer great picture quality, and now that they are competing with 4K, the prices are rock-bottom. If you want to go larger than 24 inches, though, you should consider 2,560 x 1,440 resolution at the least and perhaps 4K.

1440p: The oft-forgotten stepchild in the gradual marriage of consumers and 4K, 1440p is still the suggested resolution for gamers, as it offers a noticeable improvement in visuals over 1080p but doesn’t overly tax your graphics card. It’s also far more affordable if you’re interested in extra features like high refresh rates. It is also commonly referred to as Quad HD/QHD.

4K/Ultra HD (UHD): 4K is the resolution that the industry is most keen to drive consumers towards. It looks much more detailed than 1080p with 3,840 x 2,160 pixels, and prices have come down substantially in the past few years. That said, gamers will need a powerful graphics card to run a system at this resolution, and finding affordable monitors with full suites of frame synching support or high-refresh rates is still difficult. There is plenty of 4K media out there to enjoy, though, whether you’re streaming or using UHD Blu-rays.

5K:This resolution made headlines when Apple debuted it on its iMac, but it’s far from a common resolution even years later. Dell’s UP2715K is a great-looking display, but we would recommend many high-end 4K monitors before it, as you won’t be able to see too much difference between them.

While the above are the most common resolutions you’ll find on monitors, some fall into more niche categories. The best ultrawide monitors offer unique aspect ratios and resolutions with broad horizontal pixel counts, but less on the vertical dimension.

Several other aspects of a monitor’s display contribute to just how awesome of an image it can produce. Here are other factors to consider for your next monitor purchase:

Aspect ratio: The aspect the screen shows images in (length compared to height). A common standard, and your best bet, is 16:9. It works with plenty of content, and it’s great for movies or games. Some fancy monitors like to stretch things out with ratios like 21:9, but that is more suitable for unusual work situations or hardcore gaming. Another common format, 16:10, provides slightly more vertical space for viewing multiple open documents or images. 3:2 is becoming more commonplace in laptops for better web viewing, but that’s rare on stand-alone displays.

Brightness: High-end monitors these days have brightness around 300 to 350 cd/m2. Extra brightness may be handy if you work in a well-lit room or next to large windows. However, too much brightness is a recipe for eye strain. As long as brightness options reach 250 cd/m2, your monitor is good to go. That said, if you want one with HDR support, the more peak brightness, the better to best take advantage of that technology.

Contrast ratio: Contrast ratios tell you the difference between how white and how black a monitor screen can get. Higher contrast ratios are a good sign because that means colors will be more differentiated. However, multiple measurements for contrast ratios exist, and stated specs aren’t very reliable, so take it all with a grain of salt.

HDR: High dynamic range, or HDR, is a recent addition to the PC monitor space and can have a dramatic impact on visuals. However, most PC monitors lack the brightness needed to take full advantage of it, and even the best ones don’t look as good as they should. Keep in mind there are a variety of HDR versions to consider, like HDR10+, for more advanced content.

Refresh rate: Rated in hertz (Hz), a monitor’s refresh rate is how often it updates the image on your screen. While most support up to 60Hz, some displays now offer much higher refresh rates. That can result in smoother movements on your desktop and support for higher frame rates in games, which can make a big difference in high-paced titles by reducing your input lag. 120Hz to 144Hz is a great range to target, but you could opt for the fastest screens out there with up to 240Hz support. Just make sure you have a high-powered graphics card to back it up.

Response time: Response time indicates how quickly the monitor shows image transitions. A low response time is good for fast-paced action video, twitchy gameplay, and similar activities. Response times are measured in milliseconds, with the best screens able to switch pixels at only a couple of milliseconds, but not everyone needs such fast reactions.

Viewing angle: Viewing angle isn’t as important for a monitor as it is for a TV screen, but if you like to watch shows on your computer with groups of friends, aim for a larger viewing angle so people at the sides can see easily. Anything above 170 degrees is good news here.

The type of panel used to make your new display can have a major impact on what it looks like and how it performs. They all have their strengths and their weaknesses, making them better suited to different sorts of PC users. While manufacturers have made valiant attempts to bridge the gaps between the types, each tends to still have its evangelists, and depending on what you spend most of your time doing while on your PC, you’ll likely want to opt for one over the other. There can be a cost to pay for certain features, though.

TN: The most common panel type, Twisted Nematic (TN) displays offer good visuals and some of the fastest response times, making them great for gamers. But colors can look a little washed out, and viewing angles aren’t great. Displays with TN panels tend to be the most affordable.

IPS: Displays with IPS panels tend to be the most expensive of the bunch, but what you get for your money is much richer colors and clear viewing angles that are near horizontal. The downside of IPS panels is that they don’t tend to have as fast response times as TN displays, so some consider them inferior for gaming. There are, however, gaming IPS displays, like the fantastic Asus PG279Q, which make good ground on their TN counterparts. Some IPS monitors suffer from quality control issues, though, and most IPS displays have a telltale glow when displaying dark images due to backlight bleeding.

A curved screen can provide a more immersive experience, especially when it comes to certain games (racing games are a favorite for curved ultrawides). This largely benefits single-player games where a user will be comfortable sitting at the center of the screen.

They have a narrow field of view, and aren’t that great for group watching. Fortunately, this is less of an issue on monitors, which tend to have an audience of one.

There are a few different ports you should look for on your monitor. Where VGA and DVI were standards of yesteryear, today, new displays ship with HDMI, DisplayPort, and USB-C connections most commonly. To make things more confusing, each of those has its own multitude of generations, which you need to be aware of if you’re planning on running a high-resolution or high refresh rate display.

To run a display at 4K resolution, you’ll need to use HDMI 1.4 at the very least, though HDMI 2.0 would be required if you want to support a refresh rate of 60Hz, which should be a bare minimum unless all you do is watch movies on it (with HDMI 2.1 being the newest version of the standard). If you want to do high refresh rate gaming, especially at higher resolutions, DisplayPort 1.4 monitors can handle up to 8K at 60Hz and 4K at up to 200Hz, so they’re better suited than HDMI in that regard. DisplayPort 2.0 is also on the way.

The slightly older, DisplayPort 1.2 connector can handle 1440p and 1080p at high refresh rates, too, so if you’re not opting for 4K, that port option should suffice for lower-resolution monitors. USB-C is an option, as it can support up to 4K resolution, but it’s not as capable as DisplayPort connections.

The most common computer monitors are compact enough to sit on a table, desk, or stand. However, if you’re in the market for an enormous monitor, the most space-efficient choice is to mount the monitor onto a wall, thereby freeing up precious floor space. In this case, look for monitors thatcome with VESA standard mountingoptions or which are compatible with them. That way, you’ll have a larger selection of mounting arms from a variety of manufacturers to choose from, rather than being limited by specific mounting options.

You’ll find a built-in webcam especially useful not just for quick communication, but also for extra protection when logging in, with features like facial recognition. However, if a monitor lacks a built-in webcam, that shouldn’t be a deal-breaker. In fact, we suggest buying a monitor and then picking out a separate webcam, which is easier to mount and adjust and can be taken offline for privacy whenever you want. Plus, upgrading or replacing a standalone webcam is a lot easier than changing a built-in camera feature.

Tip:If you"re using a wireless display adapter, connect to an HDMI port on newer TVs, then wirelessly connect your PC to it. After connecting your wireless display adapter to your TV, go to your Windows 11 PC, press Windows logo key + K to open Cast, then select your wireless display adapter.

To see which number corresponds to a display, select Start, then search for settings. Select Settings > System > Display> Identify. A number appears on the screen of the display it"s assigned to.

If you have multiple displays, you can change how they"re arranged. This is helpful if you want your displays to match how they"re set up in your home or office. In Display settings, select and drag the display to where you want. Do this with all the displays you want to move. When you"re happy with the layout, select Apply. Test your new layout by moving your mouse pointer across the different displays to make sure it works like you expect.

After you"re connected to your external displays, you can change settings like your resolution, screen layout, and more. To see available options, in Settings, select System > Display.

Windows will recommend an orientation for your screen. To change it in Display settings, under Scale & layout, choose your preferred Display orientation. If you change the orientation of a monitor, you"ll also need to physically rotate the screen. For example, you"d rotate your external display to use it in portrait instead of landscape.

There are plenty of benefits to using multi-monitor setups. Using two or three monitors can help you organize your activities or just make use of multiple open applications in a way that’s much more efficient than switching. Multiple monitors also help you multitask, such as monitoring stock prices (or watching Netflix) on one monitor while surfing the web on another.

Windows 11 lets you use as many monitors as you want as long as your graphic processor can handle it. There are next to zero risks in using more than one monitor. Read the guide below to learn how to connect your Windows 11 to multiple screens.

3. Select Extend from the options. This option will make your computer act as if you are using one large monitor but are only split between your multiple screens.

And there you have it. You are now using multiple monitors for your Windows 11 computer. If your computer cannot detect your additional monitor, go to Settings. Navigate to System > Display. Then, click the Detect button beside “Detect other display” under the Multiple displays group.

The monitor might be the most important part of your Mac’s setup–after all, you can’t use any computer without one. Because you’ll spend a lot of time looking at it, you’ll want to invest wisely. Not only will you want a monitor that provides a pleasing experience, but the quality of the images on the screen can also affect your work.

However, picking a new monitor can be daunting. Not only are there lots of manufacturers to choose from, but there are also lots of sizes, resolutions, and features to consider–and when we say lots, we mean lots. We’re here to help guide you while you shop, and we have some tips on what to look for in a monitor.

Apple sells displays for its Macs, and you could go with its offerings, but its displays are a quite bit more expensive than what third parties have. Buying from a different company may mean you may not get a feature that Apple offers, but then it may also be a feature that you don’t need, depending on how you use the monitor. Note there are compatibility issues for M1 Macs. We have a guide to monitors for M1 Macs and what you need to know before buying.

Fortunately, there are plenty of companies that have great monitors that you can use with your Mac, without having to take out a second mortgage. Our sister publications TechAdvisor and PCWorld have tested several displays, and we list their top-rated ones that we have been able to confirm work with Macs, alongside the monitors we have reviewed below. Here are our recommendations in alphabetical order.

Apple’s highly specced Pro Display XDR is a stunning piece of engineering, and we found it hard to find fault with the picture quality and colour output, but at that price and with these features this is a display for a very specific audience.

The XDR is phenomenally well-specced: it’s 32in and 6K, offering 40 percent more screen space than Apple’s 5K displays, and offers a peak brightness of 1,600 nits (or 1,000 sustained). But it comes with a seriously eye-watering price tag, especially if you want to include the Pro Stand for adjustability and pivoting.

Picture quality is maintained at ultrawide viewing angles, thanks to industry-leading polariser technology. This is so that a creative team can gather round a single monitor and evaluate a photo, video or design project without suffering a loss of consistency.

As a production display, the Studio Display is still expensive but is an affordable alternative to the Pro Display XDR. Buyers will enjoy its handsome design, good image quality, and impressive spatial audio, but you can save a lot of money by going with a non-Apple display.

Apple displays have always produced very good image quality, and the Studio Display continues that tradition. Colors are rich, contrast is good, and the brightness is suitable for most tasks.

The Studio Display has a tilt-adjustable stand, but it does not pivot between landscape and portrait modes, like the Pro Display XDR. You can get a stand that provides about four inches of height adjustment but it doesn’t come cheap. The price tag for the tilt- and height-adjustable stand is a whopping $400/£400 more.

The Alogic Clarity is a stunning looking 27-inch display with built-in hub and a fantastic height-adjustable, tilt and pivot stand. It will appeal to Mac users with its Apple looks and is even, in some ways, a superior monitor to Apple’s own Studio Display, although its 4K resolution isn’t as sharp as Apple’s 5K screen.

it looks professional and almost Apple-ish, and the support arm allows it to pivot and tilt extensively. It’s also got decent colour representation with close to 100% sRGB coverage and 83% of the P3 colour space.

The Asus ProArt PA279CV is a 4K monitor that offers accurate color and important “pro” features such as accurate gamma presets. It even has USB-C connectivity, making it an excellent choice for creators looking to upgrade from their laptop display.

It’s not a great-looking monitor, with larger than average display bevels on the plasticky chassis. It’s not luxurious but it’s fine for an office or workstation.

Acer’s Nitro XV272 costs more than a lot of 1080p monitors, but the IPS, 165Hz screen provides above-average image quality, excellent color accuracy and motion performance, and a full range of monitor-stand adjustments and a generous array of ports make it worth the cost.

It also has three video inputs, four USB ports, and a stand that feels a bit cheap but offers numerous ergonomic adjustments. These features signal that the Nitro XV272, though not expensive, is a cut above entry-level 1080p monitors.

But there’s more to the U3223QE than the panel. It’s also a fantastic business, productivity, and professional monitor loaded with image-quality options and a king’s buffet of connectivity.

The USB-C hub is crammed to the gills with connectivity. This includes multiple USB-C ports, one of which can handle up to 90 watts of Power Delivery, five USB-A ports, and ethernet.

The Alienware AW3423DW makes every other 34-inch ultrawide gaming monitor obsolete. It’s also a somewhat flawed display that won’t be ideal for everyone.

PC gamers will love this monitor. SDR image quality is great straight out of the box, providing a sense of dimensionality and realism that’s a cut above the competition.

Gigabyte’s M27Q X doesn’t look like much out of the box, but this 1440p/240Hz IPS panel delivers a superb media experience where it counts, with excellent motion clarity and stunning image quality for an HD screen.

Display technology is a bit of a movable feast, with a lot of confusing jargon and technical features to wade through, as well as a variety of different interfaces and cables that are used by Apple itself and the various monitor manufacturers. So it’s worth taking a closer look at some of the factors that you need to think about when buying a monitor for your Mac.

Size isn’t everything, as the saying goes, but it’s a good place to start. Your decision will be influenced by how much desk space you have, and how comfortable you are while using the display. Some people think that a big screen is best, but then when they start to use it daily, they find that it’s too big. And the same goes for customers who think a small screen is best.

For professionals—graphics, video, audio, even spreadsheets—a large screen will help you be more productive. Think 27 inches and higher. You’ll be able to fit more elements on the screen and not waste your time scrolling.

If on-screen real estate is valuable to you, consider a multi-display setup. A smaller screen can be used for things like chat, email, web, and more, while the bigger screen is your main workspace. Or get screens of the same size and maximize the space.

Screen resolution can go hand-in-hand with screen size. Screen resolution refers to the number of pixels used to create what you see on the screen. The higher the resolution, the more detail you can see. Larger displays tend to have more resolution options, as well as the ability to support higher resolutions.

Often, when you find two displays that are the same size but have a wide price difference, it’s mostly because of the screen resolution. Monitors with high resolutions are more expensive. For example, Apple’s $1,599 Studio Display is 27 inches, and it has a high screen resolution of 5120×2880 (5K resolution). On the other hand, LG sells the 27-inch 27UK650-W, but it’s a 3840×2160 (4K) resolution display for content creators, and it’s $350–lower resolution, but $1,249 cheaper. (There actually aren’t other 27-inch 5K monitors available, except for the $1,449 LG UltraFine 27MD5KL-B.)

How a monitor connects to a Mac can be confusing. The traditional HDMI and DisplayPort connectors used by many monitors are being replaced–or complemented–by USB-C and Thunderbolt ports. And though USB-C and Thunderbolt cables may look the same, there are actually some important technical differences between them, so it’s important to check which ports your new monitor uses and make sure you buy the correct cables and adapters.

Most recent Mac models have Thunderbolt ports, so if you buy a monitor that has HDMI or DisplayPort interfaces only, then you’ll need an adapter to connect to the Mac. This can get a bit confusing, but Apple does provide a list of the ports included on most recent Mac models so that you can figure out what you need.

Apple also provides a guide to HDMI and DisplayPort technology, which covers Mac models going right back to 2008, so that should provide all the info you need for all the Macs you use at home or at work. Less expensive monitors still tend to use HDMI and DisplayPort, and while it’s not too costly to buy adapters that will allow you to connect your Mac, we reckon it’s worth future-proofing your new monitor by getting one that includes at least one USB-C or Thunderbolt port.

If a display uses Thunderbolt to connect to the Mac, it may have additional USB-C or Thunderbolt ports so the display can act as a hub. In this case, If you have a device you want to connect to your Mac, you can connect it to one of the ports on the monitor, which is already connected to the Mac and probably in an easier location for access.

If you’re going to spend a lot of time sitting at a desk looking at your lovely new display then you need to keep ergonomics in mind. The ability to tilt the angle of the monitor back and forth, swivel it around for easy viewing, and adjust the height of the monitor in order to avoid an aching back or neck.

As a rough guide, there is a point at about 2 to 3 inches from the top of the screen that should be at eye level. Obviously, eye level varies from one person to another, so it’s important that you can adjust the screen for your own personal comfort. You may also prefer a monitor that doesn’t suffer from glare, or you will be forever repositioning the monitor (or your head) to compensate for that.

There are other considerations you’ll want to make when shopping for a monitor. A lot of these come down to personal preference or what you need for the work you do. They include:

Whether in the office, home office, or for gaming – two screens are better than one. However, setting up dual monitors depends somewhat on available connections and cables. Read on to find out how to connect a second screen to a laptop or PC.

The majority of modern laptops and PCs support connecting a second monitor by default. All you need to consider are the ports on your end device and which monitor you’d like to connect. Before you head out to purchase one, be sure to check the type and number of ports on the laptop or PC.

HDMI (High-Definition Multimedia Interface) is one of the most common connection types of modern monitors and many TV users will already be familiar with it. The connection type is compact and transmits video and audio signals. A modern HDMI connection is suitable for 4K resolutions and a frame rate of 60 Hz. If your monitor and laptop or PC have one or two HDMI ports, you just need a single HDMI cable. If you want to connect two monitors but only have one HDMI port, use an HDMI splitter. Be sure that the splitter has the same refresh rate as the HDMI cable.

USB-C is a USB port format that’s often found on new, slim laptop models. The advantage of USB-C is that it can be used for charging while also supporting the transmission of audio and DisplayPort signals with Alternate Mode. DisplayPort refers to monitor interfaces for image and sound signals and high transfer rates. The USB-C downstream and DisplayPort Alternate Mode can be used to link several monitors. If you only have a few USB-C ports, use a USB-C dongle. Ideally, a USB-C donglehas at least two HDMI interfaces for monitors. Alternatively, a dongle can be paired with a HDMI splitter.

DisplayPort is similar to HDMI and transmits audio and image signals at high frame rates. Thus, the connection is particularly suitable for 4K. Laptops often have a DisplayPort or miniDisplayPort and can be connected to monitors that have a DisplayPort port. For monitors without DisplayPort, a corresponding adapter is required. Thanks to multi-stream transport, multiple monitors can be connected via DisplayPort and coupled to a laptop via a splitter or adapter.

DVI and VGA are analog, older connection standards that only transmit image signals. If the monitor and end device have DVI or VGA ports, they can be connected via the corresponding DVI or VGA cable. With the appropriate DVI-HDMI or VGA-HDMI adapter, older monitors can be connected to laptops and PCs to transmit HDMI signals. Modern connection standards are preferable in any case, as they offer better resolution, refresh rates, and color values.

Once you connect one or more monitors to your laptop, you can set up two or more monitors in Windows and specify which monitor you wish to use as the main one. Windows usually detects display devices connected to the laptop or PC automatically and assigns numbers to them. The main monitor is designated number 1. All others are numbered in ascending order.

Step 2: Under “Display” and “Multiple displays” you will see display devices detected by Windows, e.g. one or more additional monitors. Click “Detect” if none are visible.

Step 3: Go to “Advanced display settings” to make changes to the arrangement and order of the connected monitors. Adjust further settings such as the screen resolution, for example.

Step 4: The easiest way to change the use mode of the connected monitors is to use the shortcut [Windows] + [P]. Settings such as “Duplicate” let you mirror desktop content. With “PC screen only” or “Second screen only” you determine whether you only use one of the connected screens. Use “Extend” to create a connected desktop from connected monitors. These options can be found in the “Display” menu under “Multiple Screens”.

Another problem could be that Windows displays a second monitor as the main monitor. If you want to keep the PC or laptop as your main monitor, go to “Settings” > “System” > “Display Device” and select the “Rearrange Display Devices” option. Then click on “Identify”. You should be able to see the assigned digit on each screen. If you wish to change the order, go to “Advanced display settings”.

A computer monitor is an output device that displays information in pictorial or textual form. A discrete monitor comprises a visual display, support electronics, power supply, housing, electrical connectors, and external user controls.

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.

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.

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.

Some of the earliest home computers (such as the TRS-80 and Commodore PET) were limited to monochrome CRT displays, but color display capability was already a possible feature for a few MOS 6500 series-based machines (such as introduced in 1977 Apple II computer or Atari 2600 console), and the color output was a speciality of the more graphically sophisticated Atari 800 computer, introduced in 1979. Either computer could be connected to the antenna terminals of an ordinary color TV set or used with a purpose-made CRT color monitor for optimum resolution and color quality. Lagging several years behind, in 1981 IBM introduced the Color Graphics Adapter, which could display four colors with a resolution of 320 × 200 pixels, or it could produce 640 × 200 pixels with two colors. In 1984 IBM introduced the Enhanced Graphics Adapter which was capable of producing 16 colors and had a resolution of 640 × 350.

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.

Display resolution is the number of distinct pixels in each dimension that can be displayed natively. For a given display size, maximum resolution is limited by dot pitch or DPI.

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.

Color accuracy - measured in ΔE (delta-E); the lower the ΔE, the more accurate the color representation. A ΔE of below 1 is imperceptible to the human eye. A ΔE of 2–4 is considered good and requires a sensitive eye to spot the difference.

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.

Response time is the time a pixel in a monitor takes to change between two shades. The particular shades depend on the test procedure, which differs between manufacturers. In general, lower numbers mean faster transitions and therefore fewer visible image artifacts such as ghosting. Grey to grey (GtG), measured in milliseconds (ms).

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.

The size of a display is usually given by manufacturers diagonally, i.e. as the distance between two opposite screen corners. This method of measurement is inherited from the method used for the first generation of CRT television, when picture tubes with circular faces were in common use. Being circular, it was the external diameter of the glass envelope that described their size. Since these circular tubes were used to display rectangular images, the diagonal measurement of the rectangular image was smaller than the diameter of the tube"s face (due to the thickness of the glass). This method continued even when cathode-ray tubes were manufactured as rounded rectangles; it had the advantage of being a single number specifying the size, and was not confusing when the aspect ratio was universally 4:3.

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.

Estimation of monitor size by the distance between opposite corners does not take into account the display aspect ratio, so that for example a 16:9 21-inch (53 cm) widescreen display has less area, than a 21-inch (53 cm) 4:3 screen. The 4:3 screen has dimensions of 16.8 in × 12.6 in (43 cm × 32 cm) and area 211 sq in (1,360 cm2), while the widescreen is 18.3 in × 10.3 in (46 cm × 26 cm), 188 sq in (1,210 cm2).

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 for such monitors, i.e. besides Field of view in video games and movie viewing, are 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 2010, the computer industry started to move over from 16:10 to 16:9 because 16:9 was chosen to be the standard high-definition television display size, and because they were cheaper to manufacture.

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.

Every RGB monitor has its own color gamut, bounded in chromaticity by a color triangle. Some of these triangles are smaller than the sRGB triangle, some are larger. Colors are typically encoded by 8 bits per primary color. The RGB value [255, 0, 0] represents red, but slightly different colors in different color spaces such as Adobe RGB and sRGB. Displaying sRGB-encoded data on wide-gamut devices can give an unrealistic result.Exif metadata in the picture. As long as the monitor gamut is wider than the color space gamut, correct display is possible, if the monitor is calibrated. A picture which uses colors that are outside the sRGB color space will display on an sRGB color space monitor with limitations.Color management is needed both in electronic publishing (via the Internet for display in browsers) and in desktop publishing targeted to print.

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 laptops provide a method of screen dimming after periods of inactivity or when the battery is in use. This extends battery life and reduces wear.

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.

A combination of a monitor with a graphics tablet. Such devices are typically unresponsive to touch without the use of one or more special tools" pressure. Newer models however are now able to detect touch from any pressure and often have the ability to detect tool tilt and rotation as well.

The option for using the display as a reference monitor; these calibration features can give an advanced color management control for take a near-perfect image.

A desktop monitor is typically provided with a stand from the manufacturer which lifts the monitor up to a more ergonomic viewing height. The stand may be attached to the monitor using a proprietary method or may use, or be adaptable to, a VESA mount. A VESA standard mount allows the monitor to be used with more after-market stands if the original stand is removed. Stands may be fixed or offer a variety of features such as height adjustment, horizontal swivel, and landscape or portrait screen orientation.

The Flat Display Mounting Interface (FDMI), also known as VESA Mounting Interface Standard (MIS) or colloquially as a VESA mount, is a family of standards defined by the Video Electronics Standards Association for mounting flat panel displays to stands or wall mounts.

A fixed rack mount monitor is mounted directly to the rack with the flat-panel or CRT visible at all times. The height of the unit is measured in rack units (RU) and 8U or 9U are most common to fit 17-inch or 19-inch screens. The front sides of the unit are provided with flanges to mount to the rack, providing appropriately spaced holes or slots for the rack mounting screws. A 19-inch diagonal screen is the largest size that will fit within the rails of a 19-inch rack. Larger flat-panels may be accommodated but are "mount-on-rack" and extend forward of the rack. There are smaller display units, typically used in broadcast environments, which fit multiple smaller screens side by side into one rack mount.

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.

A panel mount computer monitor is intended for mounting into a flat surface with the front of the display unit protruding just slightly. They may also be mounted to the rear of the panel. A flange is provided around the screen, sides, top and bottom, to allow mounting. This contrasts with a rack mount display where the flanges are only on the sides. The flanges will be provided with holes for thru-bolts or may have studs welded to the rear surface to secure the unit in the hole in the panel. Often a gasket is provided to provide a water-tight seal to the panel and the front of the screen will be sealed to the back of the front panel to prevent water and dirt contamination.

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.

According to an NSA document leaked to Der Spiegel, the NSA sometimes swaps the monitor cables on targeted computers with a bugged monitor cable in order to allow the NSA to remotely see what is being displayed on the targeted computer monitor.

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.
