Dell Technologies recommends ensuring that the device drivers and BIOS are up to date using the SupportAssist application for optimal video performance and to help resolve common video-related issues.
NOTE: When SupportAssist does not show up in the search results, go to the SupportAssist for PCs and tablets page for information about downloading and installing SupportAssist.
It is essential to verify if the problem is inherent with the monitor, video card (GPU) or video settings on your computer. A straightforward way to identify this is to connect the computer to a known-good external monitor or TV and ensure that the display cable (S-video, VGA, DVI, HDMI, DisplayPort, USB-C, or Thunderbolt 3) is firmly connected to the video port on the computer and the monitor.
If the issue persists on the other monitor it may be due to the video card (GPU) or video settings and not the monitor, go to the step Verify display or video issue in Windows Safe Mode. Else go to the next step.
Performance issues may occur if there is any type of damage that is caused to the display cables or the LCD screen. LCD screen may show that symptoms like LCD screen stops working, work intermittently, color mismatch, flickering, display horizontal or vertical lines if there is damage to the display cables or the LCD screen.
NOTE: Self-test feature check (SFTC) helps check if the Dell monitor is working normally as a stand-alone device. To check for screen abnormalities such as flickering, distortion, clarity issues, fuzzy or blurry image, horizontal or vertical lines, color fade, and so on, run the integrated self-test (BIST) or integrated diagnostic (BID) test.
Dell monitors can be reset to factory default settings using the on-screen display (OSD) menu. This can be accessed using the buttons or joystick that is available on the Dell monitor. For step-by-step instructions to reset a Dell monitor to factory default settings, see the User Guide of your Dell monitor at the Dell Manuals website.
Display settings like brightness, refresh rate, resolution, and power management may affect the performance of your Dell monitor. Changing the display settings can help resolve several types of video issues.
NOTE: Connect the USB upstream cable from your Dell touch-capable monitor to a working USB port on the computer. This is essential for the touch feature to work.
System Restore is an integrated Windows tool that is designed to protect and repair the operating system. When something goes wrong with your computer, System Restore must be used before restoring the computer to factory defaults or reinstalling the operating system.
Dell computers are built with a small amount of hard disk space that is reserved for reinstalling your operating system. This method is the easiest way to restore your computer to factory condition. The restoration process deletes all user data from the computer, back up all your files before starting this process.
It is such a waste to only use the LCD for desktop computers. Connecting it up with a laptop PC has many merits for the user and can also bring out the latent power of the laptop.
Note: Below is the translation from the Japanese of the ITmedia article "The dual display in Windows 7 is now even more convenient" published March 1, 2010. Copyright 2011 ITmedia Inc. All Rights Reserved.
Most laptops have a handy "external display output" port. It can be used in the home to transmit videos played on the laptop to a large screen TV or, in the office, to connect up with a projector for presentations. In fact, there must be many users who already use it like this. However, people tend to use just the laptop in their daily routine and there are probably not so many cases where they use the external display output.
A laptop can be put to more effective use if it is connected to an external LCD. The photograph shows an EIZO 23-inch wide-screen LCD connected by HDMI to a Sony VAIO C laptop (VPCCW28FJ/R).
This time we would like to suggest a style that can be used in both the home and the office, where a laptop and stand-alone LCD remain connected. A laptop already has an LCD, but using it with an additional stand-alone LCD offers various merits. Not only does it make the laptop environment more pleasant and convenient, it also expands the potential of the computer itself, for example by making it possible to use it for new purposes.
Even if the LCD is already connected to a desktop computer and being used for something other than the laptop, most monitors nowadays have two or more video inputs and they tend not to use this capability to the full. It is such a waste to let the laptop"s external display output function and the monitor"s video input function remain dormant, so we would like them to be put to effective use. Of course, we would also recommend the introduction of a new LCD to connect to your laptop.
The biggest merit of connecting a laptop with a stand-alone LCD is that it gives you a large screen and high resolution dual display environment. Standard laptop models usually come with a built-in 13-inch to 15-inch wide-screen LCD with a 1280 × 800 dot or 1366 × 768 dot resolution.
This level of resolution is good enough for basic Windows operations, but it goes without saying that a large, high-resolution computer screen is much more user-friendly. Combining a laptop with one of the latest wide-screen monitors enables you to easily construct a large-screen, high-resolution dual display environment. It is a real boon to dramatically boost the screen size and resolution while continuing to use your familiar laptop.
In particular, the increased vertical resolution makes applications such as web browsers and document display and editing far easier to use. For example, you can do things like check things with the web browser, refer to pdf files, organize data using word processing or presentation software, and create spread sheets and documents without having to change windows.
Another plus is that you can create the luxury of a "watching while" environment where you run the web browser, for instance, on the laptop"s built-in LCD and watch the video content on the large screen of the external monitor. This can be really useful for hobbies too. For example, while playing a game on the large external LCD screen you can check out strategies on websites, post information on a BBS or communicate with other users.
You can smoothly use multiple applications at the same time in the large workspace provided by a dual display. The photograph shows an EIZO 24.1-inch wide-screen LCD, the FlexScan SX2462W connected to a VAIO C. By supplementing the laptop"s built-in 1366 × 768 dot 14-inch wide-screen LCD with a 1920 × 1200 dot 24.1-inch wide-screen, it is possible to show more data at a time, a huge boost to work efficiency.
With two screens it"s easy to have full-screen display of the video content on one screen while you operate the computer on the other. The photograph shows an EIZO 23-inch wide-screen LCD monitor connected to a VAIO C. The VAIO C has HDMI output and the LCD monitor has HDMI input so visuals and sound can be transmitted by a single HDMI cable. The LCD monitor has full HD screen resolution (1920 × 1080 dot), making it the perfect match for HD video content.
At the office, it is very helpful for presentations to use "clone view" for the laptop"s built-in LCD and the external LCD screen. Clone view means showing exactly the same content on two display screens. It is normally set by a graphics driver function.
When holding small meetings it is certainly very convenient to be able to offer simple explanations of the presentation materials displayed on the external LCD, rather than having to ready a projector. Being able to explain about what is displayed on the screen means fewer documents to distribute, helping your office to "go paperless", which can only be a good thing.
We would like to point out here that you should check in advance the maximum resolution that the laptop"s external display output can handle. This can be found in documents such as the laptop"s specifications chart and support information. This is because, although most laptops can handle output up to 1920 × 1080 dots or 1920 × 1200 dots, some slightly older computers have an upper limit of 1680 × 1050 dots or 1600 × 1200 dots.
Even if the upper limit is 1680 × 1050 dots, the LCD can still display the data if its own resolution is 1680 × 1050 dots or higher. In such cases, it is better to use a monitor that offers dot-by-dot display, which displays the input resolution as it is, or enlarged display, which maintains the screen"s aspect ratio as it is. You do not need to worry because EIZO wide-screen LCDs can handle such display methods (although in some cases they do not function properly depending on the laptop computer or input resolution).
This is an example of a low-resolution display on the 1920 × 1200 dot display SX2462W. Since dot-by-dot display outputs the physical "1 dot" of the LCD and the input resolution "1 dot" without enlargement or reduction, it is shown small in the center of the screen (photo on the left). The display is a little blurred if it is enlarged while maintaining the aspect ratio, but this method is suitable for displaying images as they are shown large with low resolution to make the most of the screen size (photo on the right). Many monitors that cannot handle such display methods enlarge the display to full screen regardless of the input resolution. In such cases you have to be careful as the aspect ratio of the image is altered (for example, people appear to be thinner or fatter).
It is easy to set up a dual display in Windows 7. A menu is displayed when you right-click on the desktop. From "Screen resolution" it is possible to detect and align the external LCD, and set details such as resolution, display method and which will be the main display screen.
The "Screen resolution" menu. If the external LCD is not automatically recognized, click on "Detect". After the monitor has been recognized, you can select the display mode from the "Multiple displays" drop-down menu. Select "Extend display screen" to make the laptop screen and the external LCD into a single display screen (dual display).
Select "Duplicate display screen" from the "Multiple displays" drop-down menu to display the same content on the laptop screen and the external LCD screen (clone view). With this drop-down menu you can also set it to display video on one of the LCDs.
You can also call up a settings menu to decide the display method for a projector or external display by pressing the "Windows" and "P" keys. This is a tip worth remembering as selecting "Extension" for dual display or "Duplicate" for clone view here allows you to switch swiftly between them as necessary.
The menu launched by simultaneously pressing the "Windows" and "P" keys. You can easily switch between display methods such as dual display or clone view.
It is also worth noting that Windows 7 has added functions so that dual display can be used more effectively. An active window can be moved to the screen of another LCD by simultaneously pushing "Windows" + "Shift" + "→" (or "←"). It is also possible to maximize the window by pressing "Windows" + "↑", minimize it by pressing "Windows" + "↓", and shift it to the left or right of each screen by pressing "Windows" + "→" (or "←"). Making good use of these shortcuts should enable the efficient placing of windows in the two screens.
We would recommend a wide-screen model with a screen resolution of 1920 × 1080 dots (Full HD) or 1920 × 1200 dots (WUXGA) as the LCD to connect to a laptop, so that you can make full use of the advantages of dual display. EIZO has an extensive line up of wide-screen LCDs which can offer many benefits, in addition to the merits of a large screen and high resolution, when used with a laptop for dual display.
One such feature is the flexible stand adjustment. For example, the tilt, swivel and height can be adjusted for the FlexScan SX2462W, a 24.1-inch WUXGA model, and the FlexScan EV2333, a 23-inch full HD model. This enables users to adjust the screen position for easy viewing according to their own posture, which not only boosts work efficiency but also reduces physical strain.
The SX2462W stand. The simultaneous adjustment of its tilt, swivel and height enables the optimum screen position to be aligned for its operating environment.
The SX2462W is also equipped with vertical display function, turning the screen through 90 degrees. Vertical display is really handy when viewing elongated documents, graphics or web pages. In addition, when used as a standard horizontal screen, a 24.1 wide-screen, with its 518.4 × 324.0 mm display area, can display two A4 sheets, in other words one A3 (420 × 297 mm) in actual size. As well as being very useful in areas such as graphics or desk top publishing, this is also bound to come in handy when checking large business or accounting documents.
Setting the connected monitor into a vertical position is very convenient when displaying elongated web pages and documents or photographs that were taken vertically
With a 24.1 inch wide-screen like the SX2462W, an A3 sheet (two A4 sheets side by side) can be viewed in actual size, particularly effective for paper-based creative work ITmedia LCD Course II, Lesson 3: Which is better, 16:10 or 16:9 ? – "Screen size / resolution / aspect ratio"
We must not forget that EIZO"s wide-screen LCDs have non-glare screens (processed to reduce ambient light reflection). Nowadays the trend is for laptops to have an LCD with glare (glossy) surface treatment. While these can display images in bright color, reflected ambient light can sometimes be distracting.
A laptop screen is not so large and adjusting its angle can avoid the reflection of lights and so on, however it is not so easy with the large screen of an external LCD. When it comes to the large screen of an LCD in habitual use, a non-glare type that is not reflective is probably easier to see, as well as being kinder on the eyes. A large screen, high resolution and non-glare ensure that you can comfortably continue viewing over a prolonged period of time.
The surface treatment of an LCD makes a difference to the background reflection. Glare panels do not diffuse background light, making it easier to achieve high color purity, but easily reflect the user or lights (photo on the left). If the lights are similarly trained on a non-glare panel they do not have much effect, only appearing as a fuzzy brightness (photo on the right).
Another distinctive feature of EIZO wide-screen LCDs is a commitment to energy saving. They incorporate various power saving features that support "EcoView". A pivotal feature is the "EcoView Sense" adopted in the FlexScan EV series, such as the EV2333W.
This is the motion sensor on the front of the LCD. It constantly monitors the user"s movements to automatically take finely-tuned power saving measures. To be more precise, if the user"s presence is not detected for a specified period of time, for example if he leaves his seat, the monitor automatically switches to power save mode, and then automatically switches back when the user"s presence is detected again.
Other features include "Auto EcoView", which automatically optimizes the brightness of the LCD based on ambient lighting, and "EcoView Index", which displays a meter on the screen showing how much power is being saved. All these features can be expected to have a strong energy saving effect and to boost the user"s awareness of power saving, making them particularly useful in the office.
A standard laptop computer switches to sleep mode if the built-in LCD is closed while it is running but, if this function is turned off, a laptop can be treated as a "small desktop computer."
It can be set to use only the connected external LCD and not to react when the laptop"s built-in LCD is closed. The transformation into a small desktop PC is complete if you add a keyboard and mouse connected to the laptop via USB ports, for example. The OS is still running even though the laptop"s built-in LCD is closed, so you can carry out normal operations using the external keyboard and mouse, and also use the laptop"s built-in optical drives.
The idea is to use a large screen, high resolution external LCD at home or in the office, and to use the laptop"s built-in LCD as usual for mobile purposes. This helps to boost the longevity of the laptop"s built-in LCD and many people do use their laptop in this way. If you feel reluctant to use a dual display environment, where the screen is split in two, why not give this a try?
Select "Only show the desktop on 2" from the "Multiple displays" list in the "Screen resolution" menu. The laptop"s built-in LCD will be switched off and the external LCD will become the main display.
By making this simple setting your laptop can be used as a space saving desktop computer. Another plus is that the laptop"s built-in LCD will last longer.
Recently some high-end laptop computers, such as the Sony VAIO F, are insisting on good display quality for their LCDs. However, a typical laptop"s built-in LCD does not have as good image quality as a stand-alone LCD. This is only natural since the costs allowed for display quality are completely different for an LCD incorporated into the PC as one of its parts and a specialized LCD.
However, by using an EIZO wide-screen LCD a laptop user can still fully enjoy such benefits of a stand-alone high-quality LCD as excellent color reproduction, a wide viewing angle, more even display and a wealth of items that can be adjusted to improve image quality. This is a crucial point for people who use their computer for photographs and videos in particular.
EIZO"s wide-screen LCDs emphasize color reproduction, and the coloration in sRGB mode has a high degree of accuracy. The standard color gamut used in PC environments and Internet content is sRGB, so you need have no worries about viewing or editing videos and photographs. They can also display images on web pages, such as products in online shops or goods for sale in online auctions, in colors that are very close to the real thing. (This is also influenced by how the seller took the photographs and processed the images, so we cannot say that the colors will always be accurate.)
An example of sRGB color gamut image data displayed on a standard laptop and on the SX2462W. The SX2462W"s reproducibility of sRGB mode is of a considerably high standard but the color balance on the laptop has been lost. This would make it difficult to perform rigorous photo retouching.
In this case, if the image is edited on the external LCD with its high color reproducibility and the many tool palettes in the application are grouped in the laptop"s built-in LCD, there is less need to display or hide the tool palettes or to switch back and forth, and the image data to be edited can be displayed in a large form, making for more efficient work.
In this case, if the image is edited on the external LCD with its high color reproducibility and the many tool palettes in the application are grouped in the laptop"s built-in LCD, there is less need to display or hide the tool palettes or to switch back and forth, and the image data to be edited can be displayed in a large form, making for more efficient work.
When doing things like photo retouching, using software where there is a lot of switching between tool palettes it is very handy to display the image data to be edited on the external LCD with its high color reproducibility, and to gather the palette tools to be used on the laptop"s built-in LCD.
Going back to the subject of laptop computers, it is not going too far to say that applications and functions are being spoiled in laptops whose built-in LCD"s image quality is not too good. Connecting a laptop to a monitor with high image quality dispels any concerns about work that deals with colors and also helps to bring out the laptop"s potential.
Combining an EIZO wide-screen LCD with a laptop computer makes viewing videos and images even more fun. Just being able to see them on a large screen is a pleasure, but what makes it even better is that our LCDs are equipped with Fine Contrast, the optimum image quality mode for video and visuals. You can also use the Custom mode to create the image quality you prefer.
We expect that you now understand how displaying screens from a laptop computer on a stand-alone LCD can create a very pleasant environment. It feels as if your everyday laptop has been transformed into a completely different desktop machine. Even if you only use laptop computers, it is definitely worthwhile to add a stand-alone LCD.
When choosing the type of LCD the most important consideration is to choose one with overall high quality. When it comes to that, we can recommend EIZO wide-screen LCDs to a broad range of laptop users. In addition to their high image quality, EIZO wide-screen LCD are built with careful attention to detail, including non-glare screens, versatile stand features, dot-by-dot capability, abundant image quality modes, and our proprietary eco-functions. We want you to make full use of your beloved laptop computer along with an EIZO wide-screen LCD.
This time we have spoken about how an external LCD can be connected to a laptop computer, but if your main machine is a desktop computer then you probably already have a LCD.
In which case, why not consider adding a full HD (1920 × 1080 dot) or WUXGA (1920 × 1200 dot) wide-screen LCD and creating a more advanced dual display environment to further enhance your computer"s usability.
Recently many computers can handle dual display output with their chipset integrated graphics function, and nearly all of them are capable of dual display output with a stand-alone graphics card.
The dual display environment of a desktop PC has a wider range of options than a laptop computer, which is already installed with an LCD. Depending on the combination of products used you can seek for a larger screen, higher resolution and better image quality.
The photograph below shows two EIZO 24.1-inch WUXGA (1920 × 1200 dot) models being used side by side for an overwhelming super high resolution of 3840 × 1200 dots in total.
You can get a super high resolution of 3840 × 1200 dots in total by putting two 24.1-inch 1920 × 1200 dot wide-screen LCDs side by side. The advantage in this is that a larger screen and higher resolution are achieved at a lower cost than buying a single 30-inch high resolution model
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.
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.
Viewable image size - is usually measured diagonally, but the actual widths and heights are more informative since they are not affected by the aspect ratio in the same way. For CRTs, the viewable size is typically 1 in (25 mm) smaller than the tube itself.
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.
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.
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.
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.
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.
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.
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.

When it is playing video content such as a DVD, the operating system has to synchronize playback with the display redraw rate. The video frame is updated during the vertical blanking interval so that the complete, correct frame will be displayed without any tearing every time that the video card refreshes the monitor.
When windows synchronizes DVD playback with the monitor refresh rate, it synchronizes with the timing of the primary monitor. This is determined by the video driver. Some video hardware supports multiple monitors but does not synchronize the display redraw timing of the two monitors. Even though the two monitors are configured for the same refresh rate (for example, 60 Hz), the second monitor may not be refreshed at the same time. In this case, there may be unavoidable tearing on the second monitor.Resolution
If the computer system meets the hardware and software requirements to run Windows Aero, you may be able to reduce or eliminate the problem by enabling Aero. Otherwise, set the display to PC Only or Extended. For more information about Aero, go to the following Microsoft website:
If your computer does not meet the requirements for Aero, set the display to PC Only or Extended. For information about how to change this setting, go to the following Microsoft website:
If you experience noticeable cut lines or tearing, and not only when you play a DVD movie, the display may be configured to a refresh rate that one of your monitors does not support. If this is the case, you can resolve the issue by configuring the display to a refresh rate that is supported by all monitors.
Select a resolution and refresh rate that is supported by all monitors. (Your monitors may support multiple refresh rates. See your manufacturer"s documentation for information about the settings that your monitor supports.)
When you view the same image on both the notebook or All-in-One display and an external display panel (monitor, projector, or television), the image shown on the computer display might shrink to a lower resolution, with black borders around the edges of the reduced display.
This issue can occur when the native display resolution of the computer and the resolution of the external monitor are not the same. When the graphic control detects two displays, it usually defaults to the lower resolution for both devices.
To resolve this issue, disconnect the external monitor to verify that the resolution on the computer display changes back to the desired settings. Reconnect the external monitor, and then adjust the resolution settings for each device using one of the following methods:
To use Windows to control the graphic display, connect both displays, right-click the desktop, select Screen Resolution, and then change the resolution for each display. On some models, you can select an advanced option to either Duplicate the same image on both displays or Extend the desktop image across both displays.
Certain computer models that feature a high-performance chip or secondary graphics processing unit (GPU) have an advanced graphics maintenance function. Names of advanced graphics options may vary. To use an advanced graphics maintenance function (if available) to control the graphics display, right-click on the desktop and select one of the following options:
Manage performance, temperatures, and devices all from a single application. NZXT CAM is fast, efficient, and easy-to-use, allowing you to control every aspect of your computer.What Others Say
Most modern computer monitors, and even televisions, have an edge-lit LCD display that’s fundamentally similar to the first such displays sold decades ago, but that’s not where the future is headed. The twin threats of Mini-LED and OLED want to conquer the world of PC displays for themselves.
Which will win, and where is the future headed? I spoke with Ross Young, CEO of Display Supply Chain Consultants, and David Wyatt, CTO of Pixel Display (and inventor of Nvidia G-Sync), for the inside scoop.
Modern OLED displays rarely exceed 1,000 nits of brightness, and when they do, are incapable of sustaining it. LG’s C9 OLED television, for example, can’t sustain a peak brightness above 160 nits (according to testing by Rtings). Mini-LED displays like Apple’s Liquid Retina XDR, Samsung’s Odyssey Neo G9, and Samsung’s QN90A television can hit peak brightness well above 1,000 nits and sustain at least 600 nits.
Wyatt points to this as a key advantage. The best HDR standards call for up to 10,000 nits of brightness. Current consumer Mini-LED displays don’t achieve this, but it’s possible future displays will.
Such brightness is not necessary for computer monitors or home televisions and instead targets demanding niche components, such as avionics displays. Still, it hints that we’ve only seen a sliver of HDR’s real potential – and that Mini-LED and Micro-LED, not OLED, will lead the charge.
OLED’s greatest strength is the opposite of Mini-LED’s incredible brightness. The self-emissive nature of OLED means each pixel can be turned on or off individually, providing a deep, inky, perfect black level.
“Mini-LED has clear advantages in sources of supply and brightness,” Young said in an email, “but OLEDs have advantages in regards to contrast, particularly off-axis contrast, response times, and no halo effect.” The “halo effect,” also known as blooming, is the halo of luminance that often surrounds bright objects on a Mini-LED display.
The advantages of OLED add up to superior contrast and depth. You’ve likely noticed this when viewing an OLED television at your local retailer. High-quality content has an almost three-dimensional look, as if the display is not a flat panel but a window into another world.
Modern Mini-LED displays often claim to rival OLED. Apple’s Liquid Retina Display XDR, for example, lists a maximum contrast ratio of 1,000,000:1. In reality, Mini-LED still noticeably lags the contrast performance of OLED because it can’t light pixels individually. This will remain true at least until Micro-LED, which can light pixels individually, goes mainstream.
Mini-LED improves on traditional edge-lit LCD displays by improving the backlight. The LCD panel itself, however, is much the same as before and retains some flaws common to the technology.
Display quality can shift significantly depending on viewing angle, and significant blur will be visible when displaying fast motion. Both problems are inherent to LCD technology. The liquid crystals do not block light uniformly, so the image looks different from different angles, and require a few milliseconds to respond to a charge, causing blur or ghosting in rapidly changing images.
OLED is different from LCD technology. There’s no liquid crystals to twist or move. Each pixel is an organic element that creates its own light when a charge is applied. The light is emitted in a relatively uniform pattern and can turn on or off extremely quickly, removing the viewing angle and motion performance issues of LCD entirely.
Wyatt hammered this point during our conversation. The “O” in OLED stands for organic, and organic material will wear out. Indeed, exposure to light itself (and blue light in particular) wears down OLED, reducing the light produced by pixels over time.
OLED manufacturers downplay this issue. LG said in 2016 that its OLED televisions can endure 100,000 hours before they degrade to half their original maximum brightness. The company’s current OLED reliability page says that “reasonable, responsible usage” should not result in burn-in.
Want to see the effects yourself? I recommend Rting’s burn-in testing page, which shows results over a period of eight years (though, unfortunately, Rtings has not updated its result since February of 2020). This testing shows OLED degradation is indeed a thing, though its severity depends on how you use your display.
You might decide the risk is worth the reward. But if you want a display that you’ll use all day, day after day, for a decade or more, OLED isn’t the best choice. The burn-in is real.
Monitor pricing remains a sore point for PC enthusiasts. As explained in my deep-dive on upcoming OLED monitors, pricing is tied to the efficiency of production.
“OLEDs are less costly than MiniLEDs in tablets and notebooks if comparing them to Apple’s iPad Pro and MacBook Pro,” says Young. “On the other hand, in monitors, OLEDs are more expensive than MiniLEDs, and are not as bright.”
This explanation is backed up by the hardware you can buy today. OLED panels are available at reasonable prices in notebooks like the Dell XPS 13 and Samsung Galaxy Book Pro. OLED panels for monitors, on the other hand, are so expensive most manufacturers don’t even bother. The LG UltraFine 32EP950, which briefly went on sale this summer, retailed for $3,999.99.
Mini-LED is also expensive, but more affordable than OLED. Asus’ 32-inch ROG Swift PG32UQX retails for as little as $2,899.99 and Samsung’s super-ultrawide Odyssey Neo G9 is $2,499.99.
This advantage will likely continue in the near future. OLED pricing is reliant on availability of OLED panels, which are not as widely produced as LCD panels. Companies looking to build Mini-LED displays can design the backlight somewhat independently of the LCD panel and choose panels as needed based on the panel’s capabilities and pricing.
Because of this, there’s more ways for manufacturers to deliver Mini-LED displays in notebooks and monitors, which may lead to a more aggressive reduction in price.
The current OLED vs. Mini-LED battle is give-and-take. Mini-LED wins in brightness, HDR, durability, and pricing (of full-sized monitors). OLED wins in contrast, black levels, viewing angles, and motion performance.
OLED’s big break may come with the introduction of new fabs. Young says they will “lower costs significantly for 10-inch to 32-inch panels, giving OLED fabs the same flexibility as G8.5 LCD fabs, meaning the ability to target multiple applications from a single fab.” The first of these new fabs should start producing panels by 2024.
Affordable OLED seems alluring, but Wyatt champions a different approach. He believes the Micro-LED technology championed by Pixel Display will meld the strengths of LCD and OLED while ditching the weaknesses of both.
However, Micro-LED is a technology more relevant to the latter half of this decade. The more immediate fight will see OLED attempt to improve brightness and durability while Mini-LED pursues increasingly sophisticated backlights to mimic the contrast of OLED.
Personally, I think Mini-LED shows more promise—when it comes to PC displays, at least. The static images, long hours, and sustained brightness of Mini-LED displays pinches on OLED pain points, which will remain even if pricing becomes more affordable.
