Refers to a cropped image on your monitor’s screen. A setting on your monitor zooms in on movie content, so that you cannot see the outermost edges of the film.

Adjusts On-Screen Display (OSD) Menu settings. Many of these settings can activate on-screen display notifications so users do not have to reopen the menu.

The Uniformity Correction function compensates any luminance and color uniformity imbalances on the screen, such as dark spots, uneven brightness, or illegible images on the screen. With the ViewSonic® uniformity correction function, gray-scale levels become more balanced, and delta E scores are improved which increases reliability and provides the highest quality viewing experience from every monitor.

ViewSonic’s unique ViewMode feature offers “Game”, “Movie”, “Web”, “Text”, “MAC”, and “Mono” presets. These presets are specifically designed to deliver an optimized viewing experience for different screen applications.

If the screen is still not clean, apply a small amount of non-ammonia, non-alcohol based glass cleaner onto a clean, soft, lint-free cloth; then wipe the screen.

ViewSonic® does not recommend the use of any ammonia or alcohol-based cleaners on the display screen or case. Some chemical cleaners have been reported to damage the screen and/or case of the monitor.

Working with a laptop computer can be a challenge—especially if you need to multitask with multiple windows open once. But when you’re on-the-go, it isn’t practical to lug around a full-size monitor. This is where portable monitors come in: These external second screens are designed to be mobile and go where your laptop goes. The best portable monitors can dramatically increase your available screen real estate, which can improve your productivity without requiring the same weight or bulk as a dedicated monitor.

“Portable monitors are mainly aimed at business travelers looking for enhanced productivity while on the road,” notes Paul Gagnon, vice president and industry advisor on consumer technology at research firm The NPD Group. “But they can also have utility for hybrid workers or students not looking to invest in a dedicated home office setup for space or financial reasons.”

Portable monitors typically come in sizes that pair well with laptop computers—14 to 17 inches—and typically offer a baseline resolution of 1080 pixels. The larger you go in screen size or the more screens you add, the heavier your remote work setup will be. Some monitors stand apart with 2K or 4K resolution, a touchscreen display, a fast refresh rate, built-in speakers, or some combination of all four. There are many other considerations too, and we’ll help you navigate them all.

No matter which flavor of portable monitor you choose, these handy devices can help you do more in less space—wherever you may be. To guide you in your search, we’ve done the testing and research to narrow down the best portable monitors available right now.

The SideTrak Solo is a free-standing portable monitor, unlike most other models from this company that attach to your computer screen. The Solo is among the priciest models we’ve seen, but it also packs all of the features you could want in a monitor—with 4K resolution, a touchscreen and built-in speakers. It connects to your computer using a single cable and also has a built in blue light filter to help reduce eye strain.

The Newsoul MDS-15608 monitor comes in at a budget price, one of the lowest we’ve seen for adding a second screen to your setup—especially for a model with multiple inputs on the monitor itself. It displays content at 1920 x 1080 resolution, with a refresh rate of 60Hz and a 16:9 aspect ratio. This highly affordable monitor comes with a wall mount and a foldable screen cover that doubles as a stand for either horizontal or vertical use. The screen has a 178-degree viewing angle, making it useful for sharing what’s displayed on your screen with others—like a PowerPoint presentation.

The monitor connects to the laptop using a USB Type-C port for both power and imaging. It also has a second USB Type-C port and an OTG Micro-USB port for connecting additional peripherals. Its dual stereo speakers deliver 360-degree spatial audio, unusual for such a compact unit. Whether you use this monitor for everyday computing tasks, viewing photos or videos, or for playing games, it delivers a second screen at an attractive price.

Its 16:9 aspect ratio LED screen has an anti-glare coating to help with eyestrain, has a 178-degree viewing angle and is rated at a reasonably bright 300 nits. The adjustable base includes two USB 3.1 Type-C ports for connecting to your laptop. The monitor includes a protective sleeve to make it easier to take with you.

All portable monitors are, by definition, easy to tote around. But this Dell 14 Portable Monitor C1422H was designed to take portability to the next level. At a mere 1.3 pounds, it won’t add much weight to your travel bag. And at 14-inches, it pairs well with most 13- to 15.6-inch laptops, without adding the extra heft and bulk of a larger 15.6-inch portable monitor.

This screen also has a maximum brightness of 300 nits, brighter than some laptops and other portable monitors. To help prevent eye strain, it also has blue-light reduction built in. Without speakers or lots of ports, though, this monitor is all business, making it good for work but not play. It has just two USB Type-C ports, one on each side of the monitor’s adjustable base. The idea is that one port can be used to connect the monitor with your computer, while the other can be used to plug in a power adapter and utilize pass through power—both the computer and monitor simultaneously.

The Asus ZenScreen MB16AMT 15.6-inch display sets itself apart by having a built-in rechargeable battery inside its slim, two-pound chassis. This monitor offers 1,920 x 1,080 resolution at a 60Hz refresh rate and a 16:9 aspect ratio. Also built in are two 1W internal speakers for stereo sound. The 7800mAh battery lasts for up to four hours per charge.

The monitor adapts automatically to horizontal or vertical orientation. Its touchscreen works with Windows, Android and Chrome OS. The certified flicker-free backlit screen also has blue light filtering. Together, these features work to mitigate eye fatigue. The included Smart Case protects the screen during transport. It folds out to create a multi-position tabletop stand.

The ViewSonic TD1655 is a 15.6-inch touchscreen portable monitor at one of the best prices of any similar model from major manufacturers. This pick is one of the few touchscreen monitors to work with both Macs and PCs, thanks to ViewSonic’s vTouch driver. This driver enables full touch and gesture control on the display when paired with macOS Big Sur, Catalina, Monterey or Ventura running on Intel, M1 or M2 chips. The touchscreen works without the driver on Windows 10 or newer computers with USB Type-C connectivity. While the monitor lacks its own built-in battery, it can either utilize your computer’s power supply or be plugged into an electrical outlet and power both the computer and monitor simultaneously.

The TD1655 has a 16:9 aspect ratio and comes with a screen cover and a built-in stand for use in either horizontal or vertical orientation. It also comes with a passive stylus for use on the in-cell capacitive LED touchscreen. The screen is flicker-free—with a blue light filter to reduce eyestrain. And it packs two 0.8 watt speakers, plus an impressive 250 nits of brightness.

Australian start-up Espresso Displays’ eponymous V2 model comes in 13- and 15.6-inch versions with a touchscreen, along with a 13-inch version without touch. Espresso’s prices are a bit more than some competitors, but all models share the same stylish design aesthetic, plus a bevy of features other portable monitors don’t have. Take the 15.6-inch touchscreen portable monitor, for example. It has a brushed aluminum and glass chassis and a super-slim (0.2-inch) design, with a 16:10 aspect ratio display and two USB Type-C ports. The maximum screen brightness is 300 nits.

This model works with a pressure-sensitive stylus, though the tool doesn’t come with monitor and costs an extra $79. However, the stylus supports 4,096 levels of pressure sensitivity to closely mimic the feel of pen and pencil—making this a great choice for drawing or writing on screen. Other optional accessories include a choice of stands, the coolest one being the espressoStand, a $69 foldable magnetic stand for mounting the monitor for vertical or horizontal viewing. Last but not least, this pick is versatile. The Espresso comes with its own software, called Duet, allowing you to use the touchscreen on both Mac and PC laptops.

While this is a smaller size display than most, the SideTrak Swivel’s design is very different from other portable monitors. This 12.5-inch monitor has a magnetic mounting frame to attach the screen to your laptop’s existing display. It then pulls out from behind the screen when needed. This approach makes it extremely easy to transport and ensures both displays are at the same height. You can manually adjust the SideTrack’s viewing angle, or rotate the monitor 360 degrees. If you’re looking for some detachment, the Swivel’s collapsible mounting frame also allows the monitor to stand on its own using a built-in kickstand.

This version of the SideTrak Swivel Portable Monitor is compatible with Windows or Mac laptops, with a built-in display between 13 inches and 17 inches. It is not, however, compatible with Microsoft Surface devices that have their own kickstand, or with many 2-in-1 laptops whose screens may be contorted in different positions. The 16:9 monitor’s refresh rate is 50Hz (most portable monitors are at 60Hz), but its brightness is higher than others, at a maximum of 300 nits. The unit comes with the mounting plates needed to attach it safely and securely to your computer.

The Xebec Tri-Screen 2 uses a mounting frame to attach two slide-out 10.1-inch displays to the back of your laptop’s existing screen. Each Xebec display slides out from behind your laptop—one on each side of your laptop’s display—thus creating a highly portable three-display work area. Installing these two monitors and its bracket requires the supplied frame clamps, but nothing extra, like magnets or glue.

For less than $200, you can easily connect this Lepow C2S portable monitor to your laptop computer and benefit from an additional 15.4 inch screen. You get 1080p (1,920 x 1,080 pixel) resolution with a 60Hz refresh rate. The display weighs a mere 1.6 pounds and utilizes a built in (adjustable) kick stand that allows it to be positioned horizontally or vertically. The 178-degree viewing angle means you don"t need to be positioned directly in front of the monitor to see what’s displayed. Meanwhile, the dual built-in speakers generate stereo sound, although there’s also a 3.5mm audio jack for connecting headphones.

The LG Gram + View 16-Inch is one of the few portable monitors with a 2K (2,560 x 1,600 pixel) resolution display. This monitor produces crisper images than a typical 1080p display can, and it does so in vibrant color thanks to its 99% coverage of the DCI-P3 color space, a common measure of color in the film industry and a great reason to use this display for viewing movies and TV. It has a 60Hz refresh rate and 170-degree viewing angle.

With a 16:10 aspect ratio display, the Gram + View weighs just 1.5 pounds, making it surprisingly light for a 16-inch screen. The included folio cover can be used as stand in landscape or portrait orientation—handy if you want to view documents in full length, for example. This monitor has two USB Type-C ports, but it lacks an HDMI port to easily connect a console-based gaming system. It also lacks built-in speakers, so you’ll need to rely on your laptop’s sound or bring a portable Bluetooth speaker.

Beyond the portable monitors on our list above, other models abound—albeit many are from less established or unknown brands. If your goal is to find a portable monitor and save money in the process, we found these money-saving deals available now.

When selecting a portable monitor, consider how and where you expect to use the device. These details help determine your resolution and screen size requirements, as well as whether an attached screen might be a better choice.

Consider the overall size and weight of the monitor, especially if you expect to carry it along with your laptop when on the road. Smaller screen sizes are lighter than larger ones, by nature. An attached monitor may make sense for its smaller and lighter size. It also conveniently attaches to your laptop’s screen, so you can carry everything as one unit.

As a secondary monitor used for multitasking, you may find a smaller size display will accommodate your work habits and need for extra portability. Meanwhile, if your work requires photo editing, writing, drawing or annotating, choosing a second monitor with a touchscreen display will be likely be beneficial.

Many portable monitors rely on your laptop’s power, unless they come with their own built-in battery. Some monitors have a second USB Type-C port, through which you can attach your own power source. If you’re using a monitor powered by your laptop, then expect your laptop’s battery charge to run low faster. And the monitor will drain power faster still if it’s 4K, since higher resolution displays require more power. Power might be one reason brightness suffers on a portable monitor, so we advise looking for monitors with an LED backlight for a brighter display that’s usable in a well-lit environment.

This is display panel technology used by monitors to produce better colors and widen the display’s effective viewing angle. Especially if you"ll be playing games, viewing graphic or video-based content, or working with high-resolution digital images, look for a monitor using IPS. At the same time, beware lower-cost models that use less capable display technologies.

While some portable monitors have two tiny, low-powered speakers built-in, chances are the speakers built into your computer offer higher-quality audio. For the best audio experience, consider using headphones or wireless earbuds with noise cancellation, as opposed to relying on the audio that some of these portable monitors can generate. Check out our picks for the best wireless headphones and earbuds.

All non-touchscreen portable monitors can work with a Mac or a PC. Some models can work with other operating systems, such as ChromeOS or Linux, so double check the specs if you want to use the monitor with one of those operating systems. Touchscreen portable monitors are a bit trickier. All support have Windows, but only some support additional operating systems—including ChromeOS and Android. If you want to use the monitor with a Mac, look specifically for monitors with a dedicated driver or software to enable touch on the Mac. ViewSonic, Espresso and SideTrak all come with some variation of Mac software.Use your Apple iPad as a second screen for your MacBook or iMac thanks to the SideCar feature.Apple

Portable monitors are small, compact, and lightweight computer screens designed to be connected to your laptop computer to greatly expand the on-screen real estate available to run your favorite applications.

Most portable monitors rely on your laptop computer’s battery power to function—requiring just one cable to link it with your computer. This option will reduce your laptop computer’s battery life between charges. However, some portable monitors have their own built-in rechargeable battery. All are easy to transport and will likely fit within your existing laptop case, briefcase, or carry-on bag.

The best portable monitors come in a wide range of sizes. The size you choose is a matter of personal preference and should be based on your work habits and needs, as well as how much you want to spend.The SideTrak portable monitor attaches to the back of your laptop computer"s existing screen and ...

Some portable monitors are extremely compact and provide an extra 12- to 14-inch display, although it’s more common for a portable monitor to offer at least a 15.6-inch display. A few displays go up to 17 inches. Displays larger still are more cumbersome to travel with and typically need to be plugged into an electrical outlet to function, making them less portable and more like a smaller desktop monitor.

As for thickness, most portable monitors are less than 0.5 inches and the monitors themselves weigh less than two pounds. Most come with a travel case or cover—making them very easy to transport with your laptop computer. Of course, this varies based on the screen size and model you choose.

A portable monitor adds screen real estate, either doubling or tripling your screens (if you get a multi-screen model as from Xebec). This makes multitasking much easier—allowing you to view multiple applications at once. The extra screen space can be particularly useful if you’re using a laptop computer that has a smaller built-in display, such as a 13-inch ultraportable laptop.

It all comes down to what you use your computer for, whether being able to multitask is important to you and how much physical space you have to set up your equipment on a desk or flat surface. Most people discover that having two or even three screens can be extremely beneficial to increasing their productivity and making their workflow easier. However, not everyone needs a 4K resolution portable monitor or one that’s 15-inches or larger. You’ll typically save money going with a smaller display that offers 1080p resolution.

LCDs are used in a wide range of applications, including LCD televisions, computer monitors, instrument panels, aircraft cockpit displays, and indoor and outdoor signage. Small LCD screens are common in LCD projectors and portable consumer devices such as digital cameras, watches, digital clocks, calculators, and mobile telephones, including smartphones. LCD screens are also used on consumer electronics products such as DVD players, video game devices and clocks. LCD screens have replaced heavy, bulky cathode-ray tube (CRT) displays in nearly all applications. LCD screens are available in a wider range of screen sizes than CRT and plasma displays, with LCD screens available in sizes ranging from tiny digital watches to very large television receivers. LCDs are slowly being replaced by OLEDs, which can be easily made into different shapes, and have a lower response time, wider color gamut, virtually infinite color contrast and viewing angles, lower weight for a given display size and a slimmer profile (because OLEDs use a single glass or plastic panel whereas LCDs use two glass panels; the thickness of the panels increases with size but the increase is more noticeable on LCDs) and potentially lower power consumption (as the display is only "on" where needed and there is no backlight). OLEDs, however, are more expensive for a given display size due to the very expensive electroluminescent materials or phosphors that they use. Also due to the use of phosphors, OLEDs suffer from screen burn-in and there is currently no way to recycle OLED displays, whereas LCD panels can be recycled, although the technology required to recycle LCDs is not yet widespread. Attempts to maintain the competitiveness of LCDs are quantum dot displays, marketed as SUHD, QLED or Triluminos, which are displays with blue LED backlighting and a Quantum-dot enhancement film (QDEF) that converts part of the blue light into red and green, offering similar performance to an OLED display at a lower price, but the quantum dot layer that gives these displays their characteristics can not yet be recycled.

Since LCD screens do not use phosphors, they rarely suffer image burn-in when a static image is displayed on a screen for a long time, e.g., the table frame for an airline flight schedule on an indoor sign. LCDs are, however, susceptible to image persistence.battery-powered electronic equipment more efficiently than a CRT can be. By 2008, annual sales of televisions with LCD screens exceeded sales of CRT units worldwide, and the CRT became obsolete for most purposes.

The optical effect of a TN device in the voltage-on state is far less dependent on variations in the device thickness than that in the voltage-off state. Because of this, TN displays with low information content and no backlighting are usually operated between crossed polarizers such that they appear bright with no voltage (the eye is much more sensitive to variations in the dark state than the bright state). As most of 2010-era LCDs are used in television sets, monitors and smartphones, they have high-resolution matrix arrays of pixels to display arbitrary images using backlighting with a dark background. When no image is displayed, different arrangements are used. For this purpose, TN LCDs are operated between parallel polarizers, whereas IPS LCDs feature crossed polarizers. In many applications IPS LCDs have replaced TN LCDs, particularly in smartphones. Both the liquid crystal material and the alignment layer material contain ionic compounds. If an electric field of one particular polarity is applied for a long period of time, this ionic material is attracted to the surfaces and degrades the device performance. This is avoided either by applying an alternating current or by reversing the polarity of the electric field as the device is addressed (the response of the liquid crystal layer is identical, regardless of the polarity of the applied field).

The first color LCD televisions were developed as handheld televisions in Japan. In 1980, Hattori Seiko"s R&D group began development on color LCD pocket televisions.Seiko Epson released the first LCD television, the Epson TV Watch, a wristwatch equipped with a small active-matrix LCD television.dot matrix TN-LCD in 1983.Citizen Watch,TFT LCD.computer monitors and LCD televisions.3LCD projection technology in the 1980s, and licensed it for use in projectors in 1988.compact, full-color LCD projector.

Hitachi also improved the viewing angle dependence further by optimizing the shape of the electrodes (Super IPS). NEC and Hitachi become early manufacturers of active-matrix addressed LCDs based on the IPS technology. This is a milestone for implementing large-screen LCDs having acceptable visual performance for flat-panel computer monitors and television screens. In 1996, Samsung developed the optical patterning technique that enables multi-domain LCD. Multi-domain and In Plane Switching subsequently remain the dominant LCD designs through 2006.South Korea and Taiwan,

EL-WLED: The LCD panel is lit by a row of white LEDs placed at one or more edges of the screen. A light diffuser (light guide plate, LGP) is then used to spread the light evenly across the whole display, similarly to edge-lit CCFL LCD backlights. The diffuser is made out of either PMMA plastic or special glass, PMMA is used in most cases because it is rugged, while special glass is used when the thickness of the LCD is of primary concern, because it doesn"t expand as much when heated or exposed to moisture, which allows LCDs to be just 5mm thick. Quantum dots may be placed on top of the diffuser as a quantum dot enhancement film (QDEF, in which case they need a layer to be protected from heat and humidity) or on the color filter of the LCD, replacing the resists that are normally used.

WLED array: The LCD panel is lit by a full array of white LEDs placed behind a diffuser behind the panel. LCDs that use this implementation will usually have the ability to dim or completely turn off the LEDs in the dark areas of the image being displayed, effectively increasing the contrast ratio of the display. The precision with which this can be done will depend on the number of dimming zones of the display. The more dimming zones, the more precise the dimming, with less obvious blooming artifacts which are visible as dark grey patches surrounded by the unlit areas of the LCD. As of 2012, this design gets most of its use from upscale, larger-screen LCD televisions.

Today, most LCD screens are being designed with an LED backlight instead of the traditional CCFL backlight, while that backlight is dynamically controlled with the video information (dynamic backlight control). The combination with the dynamic backlight control, invented by Philips researchers Douglas Stanton, Martinus Stroomer and Adrianus de Vaan, simultaneously increases the dynamic range of the display system (also marketed as HDR, high dynamic range television or called Full-area Local Area Dimming (FLAD)

Due to the LCD layer that generates the desired high resolution images at flashing video speeds using very low power electronics in combination with LED based backlight technologies, LCD technology has become the dominant display technology for products such as televisions, desktop monitors, notebooks, tablets, smartphones and mobile phones. Although competing OLED technology is pushed to the market, such OLED displays do not feature the HDR capabilities like LCDs in combination with 2D LED backlight technologies have, reason why the annual market of such LCD-based products is still growing faster (in volume) than OLED-based products while the efficiency of LCDs (and products like portable computers, mobile phones and televisions) may even be further improved by preventing the light to be absorbed in the colour filters of the LCD.

A standard television receiver screen, a modern LCD panel, has over six million pixels, and they are all individually powered by a wire network embedded in the screen. The fine wires, or pathways, form a grid with vertical wires across the whole screen on one side of the screen and horizontal wires across the whole screen on the other side of the screen. To this grid each pixel has a positive connection on one side and a negative connection on the other side. So the total amount of wires needed for a 1080p display is 3 x 1920 going vertically and 1080 going horizontally for a total of 6840 wires horizontally and vertically. That"s three for red, green and blue and 1920 columns of pixels for each color for a total of 5760 wires going vertically and 1080 rows of wires going horizontally. For a panel that is 28.8 inches (73 centimeters) wide, that means a wire density of 200 wires per inch along the horizontal edge.

The LCD panel is powered by LCD drivers that are carefully matched up with the edge of the LCD panel at the factory level. The drivers may be installed using several methods, the most common of which are COG (Chip-On-Glass) and TAB (Tape-automated bonding) These same principles apply also for smartphone screens that are much smaller than TV screens.anisotropic conductive film or, for lower densities, elastomeric connectors.

A comparison between a blank passive-matrix display (top) and a blank active-matrix display (bottom). A passive-matrix display can be identified when the blank background is more grey in appearance than the crisper active-matrix display, fog appears on all edges of the screen, and while pictures appear to be fading on the screen.

High-resolution color displays, such as modern LCD computer monitors and televisions, use an active-matrix structure. A matrix of thin-film transistors (TFTs) is added to the electrodes in contact with the LC layer. Each pixel has its own dedicated transistor, allowing each column line to access one pixel. When a row line is selected, all of the column lines are connected to a row of pixels and voltages corresponding to the picture information are driven onto all of the column lines. The row line is then deactivated and the next row line is selected. All of the row lines are selected in sequence during a refresh operation. Active-matrix addressed displays look brighter and sharper than passive-matrix addressed displays of the same size, and generally have quicker response times, producing much better images. Sharp produces bistable reflective LCDs with a 1-bit SRAM cell per pixel that only requires small amounts of power to maintain an image.

In-plane switching is an LCD technology that aligns the liquid crystals in a plane parallel to the glass substrates. In this method, the electrical field is applied through opposite electrodes on the same glass substrate, so that the liquid crystals can be reoriented (switched) essentially in the same plane, although fringe fields inhibit a homogeneous reorientation. This requires two transistors for each pixel instead of the single transistor needed for a standard thin-film transistor (TFT) display. The IPS technology is used in everything from televisions, computer monitors, and even wearable devices. IPS displays belong to the LCD panel family screen types. The other two types are VA and TN. Before LG Enhanced IPS was introduced in 2009, the additional transistors resulted in blocking more transmission area, thus requiring a brighter backlight and consuming more power, making this type of display less desirable for notebook computers. Currently Panasonic is using an enhanced version eIPS for their large size LCD-TV products as well as Hewlett-Packard in its WebOS based TouchPad tablet and their Chromebook 11.

In 2011, LG claimed the smartphone LG Optimus Black (IPS LCD (LCD NOVA)) has the brightness up to 700 nits, while the competitor has only IPS LCD with 518 nits and double an active-matrix OLED (AMOLED) display with 305 nits. LG also claimed the NOVA display to be 50 percent more efficient than regular LCDs and to consume only 50 percent of the power of AMOLED displays when producing white on screen.

Some LCD panels have defective transistors, causing permanently lit or unlit pixels which are commonly referred to as stuck pixels or dead pixels respectively. Unlike integrated circuits (ICs), LCD panels with a few defective transistors are usually still usable. Manufacturers" policies for the acceptable number of defective pixels vary greatly. At one point, Samsung held a zero-tolerance policy for LCD monitors sold in Korea.ISO 13406-2 standard.

Some manufacturers, notably in South Korea where some of the largest LCD panel manufacturers, such as LG, are located, now have a zero-defective-pixel guarantee, which is an extra screening process which can then determine "A"- and "B"-grade panels.clouding (or less commonly mura), which describes the uneven patches of changes in luminance. It is most visible in dark or black areas of displayed scenes.

Temporal performance: the temporal resolution of an LCD is how well it can display changing images, or the accuracy and the number of times per second the display draws the data it is being given. LCD pixels do not flash on/off between frames, so LCD monitors exhibit no refresh-induced flicker no matter how low the refresh rate.

Color performance: There are multiple terms to describe different aspects of color performance of a display. Color gamut is the range of colors that can be displayed, and color depth, which is the fineness with which the color range is divided. Color gamut is a relatively straight forward feature, but it is rarely discussed in marketing materials except at the professional level. Having a color range that exceeds the content being shown on the screen has no benefits, so displays are only made to perform within or below the range of a certain specification.white point and gamma correction, which describe what color white is and how the other colors are displayed relative to white.

Limited viewing angle in some older or cheaper monitors, causing color, saturation, contrast and brightness to vary with user position, even within the intended viewing angle.

Uneven backlighting in some monitors (more common in IPS-types and older TNs), causing brightness distortion, especially toward the edges ("backlight bleed").

As of 2012, most implementations of LCD backlighting use pulse-width modulation (PWM) to dim the display,CRT monitor at 85 Hz refresh rate would (this is because the entire screen is strobing on and off rather than a CRT"s phosphor sustained dot which continually scans across the display, leaving some part of the display always lit), causing severe eye-strain for some people.LED-backlit monitors, because the LEDs switch on and off faster than a CCFL lamp.

Only one native resolution. Displaying any other resolution either requires a video scaler, causing blurriness and jagged edges, or running the display at native resolution using 1:1 pixel mapping, causing the image either not to fill the screen (letterboxed display), or to run off the lower or right edges of the screen.

Input lag, because the LCD"s A/D converter waits for each frame to be completely been output before drawing it to the LCD panel. Many LCD monitors do post-processing before displaying the image in an attempt to compensate for poor color fidelity, which adds an additional lag. Further, a video scaler must be used when displaying non-native resolutions, which adds yet more time lag. Scaling and post processing are usually done in a single chip on modern monitors, but each function that chip performs adds some delay. Some displays have a video gaming mode which disables all or most processing to reduce perceivable input lag.

Dead or stuck pixels may occur during manufacturing or after a period of use. A stuck pixel will glow with color even on an all-black screen, while a dead one will always remain black.

In a constant-on situation, thermalization may occur in case of bad thermal management, in which part of the screen has overheated and looks discolored compared to the rest of the screen.

Loss of brightness and much slower response times in low temperature environments. In sub-zero environments, LCD screens may cease to function without the use of supplemental heating.

The production of LCD screens uses nitrogen trifluoride (NF3) as an etching fluid during the production of the thin-film components. NF3 is a potent greenhouse gas, and its relatively long half-life may make it a potentially harmful contributor to global warming. A report in Geophysical Research Letters suggested that its effects were theoretically much greater than better-known sources of greenhouse gasses like carbon dioxide. As NF3 was not in widespread use at the time, it was not made part of the Kyoto Protocols and has been deemed "the missing greenhouse gas".
