computer with three display screens free sample

Want three monitors for better gaming or multitasking in Windows? You’ve come to the right place! After reading this article, you’ll know exactly what to do.

A lot of computers have a motherboard with video ports (called ‘integrated graphics’) AND a graphics card with video ports. If your computer has this setup, you’ll see two groups of video ports. But don’t be fooled by all those ports. Although you sometimes can run monitors off your integrated graphics and graphics card at the same time, you probably wouldn’t want to. Things will get pretty laggy – particularly when you switch between monitors.

Some graphics cards have more ports than you can use at once. E.g. Yours might have 3 ports, but you may only be able to use 2 at the same time. To determine how many of the ports you can use simultaneously, you’ll have to consult your graphics card’s documentation. Alternatively, you could Google it; search for the brand and model of your video card, and the number of monitors you want to run. (e.g. “Nvidia GTX 570 three monitors”).

It’s possible you have two, but it’s very unlikely you have three. So you won’t be able to run triple monitors unless you buy extra hardware, as explained below.

If your computer doesn’t have the required ports to run triple monitors, don’t give up. You may still be able to do it. ReadStep 2, below to find out how…

But before investing in a new graphics card, you should know that not all graphics cards are compatible with your PC’s motherboard. To see if a graphics card is compatible with your PC, you need to check your motherboard’s PCI Express slot, the size of your chosen graphics card and the power requirements.

There are different types of expansion slots on a motherboard. For a graphics card to be connected, you need a PCI Express x16 slot. The quickest way to find out if you have this slot is to Google your motherboard’s manufacturer and model. Alternatively, you can open up your computer case to check if you have the slot. (The PCI Express x16 slot should be the longest on the motherboard.)

You’ll need to be sure that your computer case has enough room for the new graphics card (they’re often quite bulky because they have an attached cooling fan).

If your PC doesn’t have enough power to support it, your computer may shut down unexpectedly or fail to turn on when you install the new graphics card.

Check your computer’s specifications to see how many watts the power supply unit (PSU) can provide. If you can’t find any specifications, you should be able to see the output on your computer’s power supply. You’ll need to look inside the case, for something like this:

An external multi-display adapter should be cheaper than a new graphics card – they retail for approx USD $150. They’re also much easier to install – you just plug one of the supplied cables into your USB port (this powers the adapter) and the other into your Mini DisplayPort or USB Type-C port (this sends the video signal from your computer to the adapter).

These adapters are great if you want a cheap way to get triple monitors (they cost around USD $50), but they don’t perform as well as a powerful graphics card or an external multi-display adapter. So they’re not a great choice for gaming or HD video playback.

A docking station like the one pictured above allows you to attach up to three additional monitors to your computer. You just connect your computer to the docking station with the supplied USB host cable, then connect your extra monitors to the docking station’s DisplayPort and HDMI ports.

Once you’ve confirmed that your computer has the necessary video ports to support triple monitors (or you’ve bought additional hardware to support them), you need to make sure you have all the necessary cables to connect everything.

Recall the video ports you identified on your computer in step 1. E.g. If you have two HDMI ports and one DisplayPort on your computer, you’ll need two HDMI cables and a DisplayPort cable to connect three monitors.

Next, you need to check the ports on your monitors. E.g. If you’re connecting to a computer with two HDMI ports and one DisplayPort, ideally you’ll have two monitors with an HDMI input, and one with a DisplayPort input.

If the ports on your monitors don’t match those on your computer, don’t panic. You can simply buy an adapter or an adapter cable. E.g. If your computer has a DisplayPort, but your monitor has only a VGA input, you can get either a DisplayPort-to-VGA adapter like the below, and then connect from the VGA input of the adapter to the VGA input of your monitor with a male-to-male VGA cable.

2) Click on one, then click Identify to see which illustrated monitor represents which monitor on your desk. E.g. Click on the monitor marked with a 1, and a number 1 will appear on one of the monitors on your desk.

4) If the arrangement on-screen doesn’t match how your monitors are arranged on your desk, just rearrange it by dragging and dropping with your mouse.

5)Click the drop-down menu next to Multiple displays and select Extend these displays. You’ll then seeone continuous display that stretches across all of your monitors (i.e. you can drag your mouse or windows from one screen to the other).

2) Click on one, then click Identify to see which illustrated monitor represents which monitor on your desk. E.g. Click on the monitor marked with a 1, and a number 1 will appear on one of the monitors on your desk.

4) If the arrangement on-screen doesn’t match how your monitors are arranged on your desk, just rearrange it by dragging and dropping with your mouse.

5) If you want, you can customize Scale and layoutto change the size of text, apps and other items on your screens. You can also adjust the resolution and orientation.

6)Click the drop-down menu next to Multiple displays and select Extend these displays. You’ll then see one continuous display that stretches across all of your monitors (i.e. you can drag your mouse or windows from one screen to the other).

To ensure your triple monitor setup runs smoothly, and to prevent problems like loss of signal and black screens, you should update the drivers for both your graphics card and your monitors. There are two ways you can do this:

If you don’t have the time, patience or computer skills to manually update the drivers for your monitors and your graphics card, you can do it automatically with

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

Sometimes you need a command center whether you"re gaming, coding, or working with multiple documents. Here"s how to add three monitors to your computer.

Examine the video inputs available on the three monitors you"ll be using. The ports on your PC don"t have to match the ones on your monitors, but you"ll need a cable or adapter with the appropriate connections if they are different.

Connect the video cable for the first monitor to your PC and then to the monitor. Wait a moment for the PC to detect the monitor and display an image. If it"s successful, repeat this for the second monitor and, finally, the third.

A diagram will be visible at the top of the Displaymenu. If this is your first time connecting multiple monitors, the diagram will show one rectangle with the numbers 1, 2, and 3 together. Scroll down until you find the Multiple Displays option. Click the drop-down field and then Extend these displays.

Scroll back to the top of the Displaymenu. It will now show three rectangles, each labeled with a number. These rectangles show the position of each monitor on your Windows desktop. Change the diagram so that each rectangle"s location is approximately the same as each monitor"s physical location on your desk.

A computer needs the proper hardware and software to support three monitors at once. Even one with enough physical video outputs might not support three monitors if the driver for its graphics hardware lacks support for so many displays.

The incredible diversity of PC hardware means there"s no fast, easy rule for determining whether your PC supports three monitors. You instead need to examine the physical connectors available and the published specifications for your PC"s graphics hardware.

You can tally the physical video outputs available with a glance at your PC"s ports, but there is one common exception to note. Most desktops can only handle video connections from one graphics solution at a time. You can"t use video output from a motherboard alongside video output from a video card if you have one installed.

You"ll also want to check the published specifications for your graphics hardware. Determine the hardware your PC uses with a Windows Search for Device Manager. Open Device Manager and then find Display adapters in the drop-down list. Expand this option to view the graphics hardware your PC uses.

A "splitter" is a video adapter that takes a single output and splits it into multiple duplicate outputs. It can only display a single video output on numerous monitors.

There"s no easy way to expand a PC"s display output limitation with a splitter or adapter. The only option that genuinely extends a PC"s display output is an external graphics card, one that bypasses the default graphics hardware. It"s an expensive, niche option and only works with a small selection of PCs.

Another option for connecting three monitors is a daisy chain. This option is supported by DisplayPort 1.2 and Thunderbolt 3 (or newer) and USB-C connections that include a DisplayPort mode. HDMI does not support daisy chains.

First, make sure your laptop graphics card supports three monitors. Then, connect your laptop and monitors to a dock and go to Settings> System> Display. If you don"t see all of the monitors, scroll down to Multiple Displays and select Detect.

While it"s impossible to predict the lifespan of an electronic device with 100% accuracy, you can expect most LCD monitors to last between 10-20 years under normal usage conditions. If you"re in an office setting, or you use your monitor for more than eight hours a day, its lifespan will likely be shorter.

Trying to boost your productivity with a second screen? Want more immersive gaming sessions? Multiple monitors can help. Dual displays are great for multitasking and are easy to set up, but there are a few things to consider before you wade into a multiscreen world—whether you"re on Windows or Mac.

Windows: The presence of several ports on your graphics card indicates it can likely handle multiple monitors. But you should check the maximum number of supported displays and resolutions. (You can see what graphics card you have by typing Device Manager into the Search bar, opening it, and then expanding Display adapters.) Visit the manufacturer’s website to find the specifications for your graphics card, and look for a section titled Display Support or something similar that will list this info.

You can mix and match the types of screens you have at your workstation, though you"ll likely want some consistency. The most common monitor size is 24 inches, but 27-inch screens are increasingly popular. Having the same size screens will be nice for symmetry. Just keep an eye on resolution when you buy. A 1080p screen on a 27-inch monitor might look too fuzzy.

We dive into orientation and arrangements below, but consider different types of screen arrangements. My current preference is a 34-inch ultrawide screen paired with a 27-inch screen in portrait orientation. As the name suggests, ultrawides are really wide and can deliver the experience of two screens, minus the screen"s bezel in between. Pairing it with a screen in portrait mode means you get enough space on the ultrawide to run two full-size browser windows side by side, plus a vertical screen on the side for apps that benefit from it, like Slack and email.

Monitors come with a wide assortment stand designs. If you are going with the stand that comes in the box, check the measurements on the product page to ensure it"ll fit nicely on your desk.

Alternatively, you can mount your screen to your desk and get rid of the stand, freeing up a lot of space. (You can also freely move your screen to various angles and positions.) Many displays support the VESA mount system. There are different sizes, and monitor arms have a screen size range and maximum weight they can support. Always check whether the monitor"s product page mentions VESA support, and note the VESA mount size. When you buy an arm mount, make sure it supports the screen size and weight of your new screen.

To get the most from your computer and monitors, you"ll need to think about which ports and cables to use. For Windows PCs, your choice is often HDMI vs. DisplayPort. Unfortunately, this isn’t as straightforward as you might expect. There are several versions of each connection type, each with different capabilities. For example, HDMI 2.1 supports up to 8K resolution at 120 Hz, DisplayPort 1.4 can deliver 8K at 60 Hz, and HDMI 2.0 is limited to 4K at 60 Hz.

For laptops, you might be looking at Thunderbolt, Mini DisplayPort, or even USB-C. Sometimes you will need an adapter or USB hub to connect an external monitor.

Check the technical specifications for your graphics card and monitor to find the best option for you. Remember that the card, monitor, and cable (and any adapters) you use must support the same technology and the same version. High-end monitors usually come with a selection of cables in the box, but some manufacturers annoyingly provide a single option that might not match the monitor’s top capability.

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.

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.

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.

Viewing angle is the maximum angle at which images on the monitor can be viewed, without subjectively excessive degradation to the image. It is measured in degrees horizontally and vertically.

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.

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 (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 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.

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.

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 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.
