Unused electronics are the bane of the modern life. Perfectly functional gadgets sit quietly in a corner of the store room, doing nothing. If you"re wondering what to do with old computer monitors, here are a few easy ideas to repurpose unused screens.
Perhaps the best thing to do with an old flat-screen monitor is a DIY DAKboard. The DAKboard is a LCD wall display that shows the current time, weather forecast, calendar events, stock quotes, fitness data, and news headlines. It"s all displayed on a soothing photo. You could buy an official DAKboard, but the makers themselves have shown how to build your own wall display with a Raspberry Pi. when you can build one for far less money and a little geeky fun, the choice is obvious.
Basically, you will be cutting out the polarizing film of the old LCD monitor. This film will then be put on a simple pair of glasses. Now your screen appears white, but the glasses can "see" the content. It"s one of the best ways to keep prying eyes out of your PC.
If you have a broken old LCD monitor, it can be re-purposed into a usable mirror; but if you have a working old LCD monitor, adding a Raspberry Pi can turn it into a smart magic mirror!
If you"re on a tight budget for a first-time DIY project, consider the $100 smart mirror. It"s not the best version of turning an LCD monitor into a smart mirror, but you"ll get the basic features and not spend a bomb.
All desktop operating systems support the ability to use dual monitors. It"s pretty easy to setup dual monitors on Windows, and you can then customize how you use the two spaces. To connect two monitors, you will likely need a graphics card with multiple HDMI ports, or use an HDMI and a VGA port on desktops.
Like any gadget, monitors have a limited shelf life. If you"re looking to upgrade, you now have a few ideas of what to do with your old monitor. And that age should influence which project you chose. For example, given the effort involved in building a smart mirror, don"t go with a screen that"s already shown signs of trouble. The Raspberry Pi-based projects are usually the easiest to keep changing.
Flicker-free monitors are specially designed to produce a single continuous light source. A typical monitor adjusts its brightness through flickering, introducing periods of low light between higher brightness. While a user may not be aware of the flicker, it can cause a number of issues, including eye strain. However, many monitors now use flicker-free technology to put less strain on monitor users’ eyes.
Look around your typical office and what do you see? Perched on every desk is a computer. Your reliance on computers in the workplace means that office workers are exposed to computer monitors every day, and many of them use the monitor for the majority of their work tasks.
Unfortunately, continued exposure to computer monitors can be very harmful to your eyes, causing irritation and discomfort in the short term. It may also lead to more severe issues in the long-term.
Monitors that use LED backlighting flicker through pulse-width modulation (PWM), which enables you to adjust the brightness of your screen easily. If you’re in a sunlit room, you’ll need a bright screen to help you see; when you’re working late at night, you may prefer to dim your screen accordingly.
When you use a non-flicker-free monitor, you are exposing yourself to constant on-screen flickering, which—as we’ve discussed above—can jeopardize the health of your eyes over time. Studies reveal that after only 3 to 4 hours of use of a traditional computer monitor—one that’s not engineered with flicker-free technology – 90% of computer users may experience eye fatigue.
Computer companies are beginning to address the concerns and dangers that digital displays pose to your eye health. When certain features are integrated into digital displays and computer monitors, your eyes can be successfully protected from digital eye strain.
However, implementing design changes that will have a positive impact on eye health has proven to be difficult. Many computer companies have attempted to design flicker-free monitors, but the end product fails to truly protect your eyes. In other words, not all flicker-free monitors are created equal—and some aren’t actually “flicker-free” at all.
For example, some companies have attempted to protect your eyes from on-screen flicker but have only created monitors that mask the issue or create the impression of being flicker-free.
Conventional computer monitors flicker at a fixed frequency with comparatively longer periods of time between the “on” and “off” states of the backlight. Consequently, the on-screen flicker of conventional computer monitors is very noticeable.
It may seem like we’ve arrived at a catch-22. Non-flicker-free monitors have proven to harm your eyes, and traditional flicker-free monitors still, unfortunately, fail to solve this problem. So what’s the solution?
ViewSonic has used its 30 years of visual solution experience—along with a deep understanding of how traditional computer monitors harm your eyes—to develop a line of computer monitors designed to protect your eye health.
Engineered with flicker-free technology, ViewSonic’s line of monitors is created to reduce flicker and prevent eye strain, eye fatigue, and irritation as well as the development of Computer Vision Syndrome.
Start by setting your display to peak brightness. Turn on your mobile phone camera and point it at your computer screen. Now, with your phone’s camera focused on the screen, adjust the brightness to 50% and then eventually down to 0%. As you lower the screen’s brightness, any flicker will become increasingly noticeable if it’s a non-flicker free monitor.
On-screen flicker isn’t the only problem computer users face. Companies have also tried to create monitors that protect your eyes from harsh blue light waves.
ViewSonic has designed a line of computer monitors with blue light filter technology that has been engineered to address this issue. This state-of-the-art technology helps the computer monitor maintain blue light waves that are closer in intensity to realistic, everyday colors.
To ensure that your eyes stay healthy, you need to stay aware of the potential dangers of continued exposure to computer monitors. The key is understanding how certain computer monitors can impact the health of your eyes, either positively or negatively.
When selecting computer monitors for business purposes, ensure that the monitors you choose are flicker-free for optimum eye health and include integrated blue light filter technology.
We previously recommended an older version of this display, the Asus ProArt PA247CV, as a top pick in this guide. Both monitors are fantastic, but the newer PA248CNV offers a larger, more accurate display and a higher charging wattage for only around $40 more, an extra expense that we think is worth paying. If the PA248CNV is out of stock or has jumped in price when you’re shopping, or if you don’t have a high-powered laptop that requires 90 W charging, we recommend getting the PA247CV instead.
If you’ve been reading our other monitor guides lately, you might notice that this is the 24-inch version of the top pick in our guide to the best 27-inch monitors. Although many home-use displays under $500 have fallen short of their advertised color accuracy, contrast, and brightness in our tests, we’ve found that the ProArt line often lives up to its claims (or at least gets much closer than the competition). It also prioritizes features that are essential, such as USB-C charging for laptop owners and sturdy, adjustable stands.
We generally like this monitor and haven’t found issues with it. However, as we mention in our How we picked and tested section, if you’re planning on using this monitor as your main work display, you might want to consider a higher-resolution 27-inch monitor. (Our top pick in our guide to the best 27-inch monitors is just a larger, higher-resolution version of this same monitor.) On that kind of monitor, you have more screen space, and text is a bit sharper and easier to read. But if you’re already working on a 1080p laptop screen or monitor and satisfied with the image quality, that’s great! The Asus ProArt PA248CNV will be a quality replacement or upgrade.
One of the largest recycling problems faced by most countries comes down to the sheer volume of computer electronics that are obsolete and outdated. With technology advances showing no signs of slowing down, it"s no wonder that businesses and home users are constantly upgrading computer monitors.
When e-waste like monitors isn"t properly handled at the end of its life, then exposure to the natural elements alone can cause many of the toxic materials to break down and evaporate into the air.
But even modern LCD monitors contain many different metals and chemicals that are perfectly safe when they are contained. But even small amounts of them in the open air canseriously damage animals, plants, and humans.
When monitors and other computer electronics are illegally dumped, or they end up at a landfill, then all those metals like lead, mercury, and cadmium can ultimately release due to heat, cold, and moisture exposure.
OK, now that you know that those old monitors in the garage or basement could be a health hazard and that the right thing to do is to recycle computer monitors, it"s time to go through this simple process.
Make sure that your old computer monitors are safely placed in your trunk so that they avoid falling or rolling around. Those external plastics won"t stand up to much force, and you can quickly damage internal components that contain the heavy metals.
The recycling process for computers and monitors starts with carefully taking apart the electronics into their individual components. There are plenty of plastics, and then there"s the glass and multiple circuit boards.
While they might not take care of the overall breakdown of the materials, many of them do offer to take back old computer monitors, printers, hard drives, phones, and laptops for free or a nominal fee.
Dellhas created a unique approach in that they offer a drop-off and mail-in service where they accept any brand of products. Whether it"s a Dell computer or old Canon printers, if you can attach it to a computer, they will accept it.
Many major electronics stores now offer a recycling program where you can drop off computers, laptops, TVs, monitors, and anything electrical that you bought there.
This should be your first option if you have computer monitors that are relatively modern and still in working order. Many charities and Goodwill stores will happily accept electronics that could help out people with little financial means.
If you"re in the San Francisco Bay Area and have some old monitors from personal home use, then GreenCitizen offers a free drop-off service . And the process couldn"t be any easier.
Then weigh the fee items and fill out the mail-in recycling form. All that"s left is to pay the fee online and receive the shipping instructions. You can then use your preferred shipping company to have your old computer monitors and other equipment sent to the recycling center.
Yes, old CRT monitors can be recycled. In most cases, it"s not possible to reuse them with modern computers, but they contain toxic metals that should end up in the trash or landfill.
The penalty for not recycling old computer monitors is different from state to state and county to county. In many cases, it ranges from $50 to several hundred dollars, which should be enough incentive not to throw it in the trash.
Yes, a monitor can store data. This is typically more common with smart TVs, but some monitors also have similar functions that could store login details for streaming services. It"s important that you use a data destruction service for such devices.
Blue light emissions, display flicker and glare are some of the factors that cause CVS. ASUS monitors featuring ASUS Eye Care Technology ensure comfortable viewing, while caring your eyes at the same time.
The blue light emitted from monitors can cause eye strain, headaches and even sleep disorders. Children are more susceptible to eye damage because the crystalline lens in their eye is less effective in filtering blue light, raising the risk of age-related macular degeneration.
Whether you’re looking for a monitor for work or play, ASUS has a wide range of monitors that cater to different needs. The latest ASUS monitors feature ASUS Eye Care or Eye Care Plus technologies to protect your eyes — ensuring safe and comfortable viewing experiences.
ASUS monitors feature a smart ergonomic design that offers full tilt, pivot, swivel and height adjustments to ensure that you can achieve a more natural and comfortable viewing position.
All ASUS Low Blue Light Monitors feature an easily accessible onscreen display (OSD) menu that allows you to access four different Blue Light Filter settings onscreen.
ASUS monitors feature a smart ergonomic design that offers full tilt, pivot, swivel and height adjustments to ensure that you can achieve a more natural and comfortable viewing position.
The display in modern monitors is typically an LCD with LED backlight, having by the 2010s replaced CCFL backlit LCDs. Before the mid-2000s,CRT. Monitors are connected to the computer via DisplayPort, HDMI, USB-C, DVI, VGA, or other proprietary connectors and signals.
Originally, computer monitors were used for data processing while television sets were used for video. From the 1980s onward, computers (and their monitors) have been used for both data processing and video, while televisions have implemented some computer functionality. In the 2000s, the typical display aspect ratio of both televisions and computer monitors has changed from 4:3 to 16:9.
Modern computer monitors are mostly interchangeable with television sets and vice versa. As most computer monitors do not include integrated speakers, TV tuners, nor remote controls, external components such as a DTA box may be needed to use a computer monitor as a TV set.
Early electronic computer front panels were fitted with an array of light bulbs where the state of each particular bulb would indicate the on/off state of a particular register bit inside the computer. This allowed the engineers operating the computer to monitor the internal state of the machine, so this panel of lights came to be known as the "monitor". As early monitors were only capable of displaying a very limited amount of information and were very transient, they were rarely considered for program output. Instead, a line printer was the primary output device, while the monitor was limited to keeping track of the program"s operation.
Multiple technologies have been used for computer monitors. Until the 21st century most used cathode-ray tubes but they have largely been superseded by LCD monitors.
The first computer monitors used cathode-ray tubes (CRTs). Prior to the advent of home computers in the late 1970s, it was common for a video display terminal (VDT) using a CRT to be physically integrated with a keyboard and other components of the workstation in a single large chassis, typically limiting them to emulation of a paper teletypewriter, thus the early epithet of "glass TTY". The display was monochromatic and far less sharp and detailed than on a modern monitor, necessitating the use of relatively large text and severely limiting the amount of information that could be displayed at one time. High-resolution CRT displays were developed for specialized military, industrial and scientific applications but they were far too costly for general use; wider commercial use became possible after the release of a slow, but affordable Tektronix 4010 terminal in 1972.
By the end of the 1980s color progressive scan CRT monitors were widely available and increasingly affordable, while the sharpest prosumer monitors could clearly display high-definition video, against the backdrop of efforts at HDTV standardization from the 1970s to the 1980s failing continuously, leaving consumer SDTVs to stagnate increasingly far behind the capabilities of computer CRT monitors well into the 2000s. During the following decade, maximum display resolutions gradually increased and prices continued to fall as CRT technology remained dominant in the PC monitor market into the new millennium, partly because it remained cheaper to produce.
There are multiple technologies that have been used to implement liquid-crystal displays (LCD). Throughout the 1990s, the primary use of LCD technology as computer monitors was in laptops where the lower power consumption, lighter weight, and smaller physical size of LCDs justified the higher price versus a CRT. Commonly, the same laptop would be offered with an assortment of display options at increasing price points: (active or passive) monochrome, passive color, or active matrix color (TFT). As volume and manufacturing capability have improved, the monochrome and passive color technologies were dropped from most product lines.
The first standalone LCDs appeared in the mid-1990s selling for high prices. As prices declined they became more popular, and by 1997 were competing with CRT monitors. Among the first desktop LCD computer monitors was the Eizo FlexScan L66 in the mid-1990s, the SGI 1600SW, Apple Studio Display and the ViewSonic VP140vision science remain dependent on CRTs, the best LCD monitors having achieved moderate temporal accuracy, and so can be used only if their poor spatial accuracy is unimportant.
High dynamic range (HDR)television series, motion pictures and video games transitioning to widescreen, which makes squarer monitors unsuited to display them correctly.
Organic light-emitting diode (OLED) monitors provide most of the benefits of both LCD and CRT monitors with few of their drawbacks, though much like plasma panels or very early CRTs they suffer from burn-in, and remain very expensive.
Radius of curvature (for curved monitors) - is the radius that a circle would have if it had the same curvature as the display. This value is typically given in millimeters, but expressed with the letter "R" instead of a unit (for example, a display with "3800R curvature" has a 3800mm radius of curvature.
Dot pitch represents the distance between the primary elements of the display, typically averaged across it in nonuniform displays. A related unit is pixel pitch, In LCDs, pixel pitch is the distance between the center of two adjacent pixels. In CRTs, pixel pitch is defined as the distance between subpixels of the same color. Dot pitch is the reciprocal of pixel density.
Pixel density is a measure of how densely packed the pixels on a display are. In LCDs, pixel density is the number of pixels in one linear unit along the display, typically measured in pixels per inch (px/in or ppi).
Contrast ratio is the ratio of the luminosity of the brightest color (white) to that of the darkest color (black) that the monitor is capable of producing simultaneously. For example, a ratio of 20,000∶1 means that the brightest shade (white) is 20,000 times brighter than its darkest shade (black). Dynamic contrast ratio is measured with the LCD backlight turned off. ANSI contrast is with both black and white simultaneously adjacent onscreen.
Color depth - measured in bits per primary color or bits for all colors. Those with 10bpc (bits per channel) or more can display more shades of color (approximately 1 billion shades) than traditional 8bpc monitors (approximately 16.8 million shades or colors), and can do so more precisely without having to resort to dithering.
Refresh rate is (in CRTs) the number of times in a second that the display is illuminated (the number of times a second a raster scan is completed). In LCDs it is the number of times the image can be changed per second, expressed in hertz (Hz). Determines the maximum number of frames per second (FPS) a monitor is capable of showing. Maximum refresh rate is limited by response time.
On two-dimensional display devices such as computer monitors the display size or view able image size is the actual amount of screen space that is available to display a picture, video or working space, without obstruction from the bezel or other aspects of the unit"s design. The main measurements for display devices are: width, height, total area and the diagonal.
With the introduction of flat panel technology, the diagonal measurement became the actual diagonal of the visible display. This meant that an eighteen-inch LCD had a larger viewable area than an eighteen-inch cathode-ray tube.
Until about 2003, most computer monitors had a 4:3 aspect ratio and some had 5:4. Between 2003 and 2006, monitors with 16:9 and mostly 16:10 (8:5) aspect ratios became commonly available, first in laptops and later also in standalone monitors. Reasons for this transition included productive uses (i.e. besides Field of view in video games and movie viewing) such as the word processor display of two standard letter pages side by side, as well as CAD displays of large-size drawings and application menus at the same time.LCD monitors and the same year 16:10 was the mainstream standard for laptops and notebook computers.
In 2011, non-widescreen displays with 4:3 aspect ratios were only being manufactured in small quantities. According to Samsung, this was because the "Demand for the old "Square monitors" has decreased rapidly over the last couple of years," and "I predict that by the end of 2011, production on all 4:3 or similar panels will be halted due to a lack of demand."
The resolution for computer monitors has increased over time. From 280 × 192 during the late 1970s, to 1024 × 768 during the late 1990s. Since 2009, the most commonly sold resolution for computer monitors is 1920 × 1080, shared with the 1080p of HDTV.2560 × 1600 at 30 in (76 cm), excluding niche professional monitors. By 2015 most major display manufacturers had released 3840 × 2160 (4K UHD) displays, and the first 7680 × 4320 (8K) monitors had begun shipping.
Most modern monitors will switch to a power-saving mode if no video-input signal is received. This allows modern operating systems to turn off a monitor after a specified period of inactivity. This also extends the monitor"s service life. Some monitors will also switch themselves off after a time period on standby.
Most modern monitors have two different indicator light colors wherein if video-input signal was detected, the indicator light is green and when the monitor is in power-saving mode, the screen is black and the indicator light is orange. Some monitors have different indicator light colors and some monitors have blinking indicator light when in power-saving mode.
Many monitors have other accessories (or connections for them) integrated. This places standard ports within easy reach and eliminates the need for another separate hub, camera, microphone, or set of speakers. These monitors have advanced microprocessors which contain codec information, Windows interface drivers and other small software which help in proper functioning of these functions.
Monitors that feature an aspect ratio greater than 2:1 (for instance, 21:9 or 32:9, as opposed to the more common 16:9, which resolves to 1.77:1).Monitors with an aspect ratio greater than 3:1 are marketed as super ultrawide monitors. These are typically massive curved screens intended to replace a multi-monitor deployment.
These monitors use touching of the screen as an input method. Items can be selected or moved with a finger, and finger gestures may be used to convey commands. The screen will need frequent cleaning due to image degradation from fingerprints.
Some displays, especially newer flat panel monitors, replace the traditional anti-glare matte finish with a glossy one. This increases color saturation and sharpness but reflections from lights and windows are more visible. Anti-reflective coatings are sometimes applied to help reduce reflections, although this only partly mitigates the problem.
Most often using nominally flat-panel display technology such as LCD or OLED, a concave rather than convex curve is imparted, reducing geometric distortion, especially in extremely large and wide seamless desktop monitors intended for close viewing range.
Newer monitors are able to display a different image for each eye, often with the help of special glasses and polarizers, giving the perception of depth. An autostereoscopic screen can generate 3D images without headgear.
Raw monitors are raw framed LCD monitors, to install a monitor on a not so common place, ie, on the car door or you need it in the trunk. It is usually paired with a power adapter to have a versatile monitor for home or commercial use.
A stowable rack mount monitor is 1U, 2U or 3U high and is mounted on rack slides allowing the display to be folded down and the unit slid into the rack for storage as a drawer. The flat display is visible only when pulled out of the rack and deployed. These units may include only a display or may be equipped with a keyboard creating a KVM (Keyboard Video Monitor). Most common are systems with a single LCD but there are systems providing two or three displays in a single rack mount system.
An open frame monitor provides the display and enough supporting structure to hold associated electronics and to minimally support the display. Provision will be made for attaching the unit to some external structure for support and protection. Open frame monitors are intended to be built into some other piece of equipment providing its own case. An arcade video game would be a good example with the display mounted inside the cabinet. There is usually an open frame display inside all end-use displays with the end-use display simply providing an attractive protective enclosure. Some rack mount monitor manufacturers will purchase desktop displays, take them apart, and discard the outer plastic parts, keeping the inner open-frame display for inclusion into their product.
Van Eck phreaking is the process of remotely displaying the contents of a CRT or LCD by detecting its electromagnetic emissions. It is named after Dutch computer researcher Wim van Eck, who in 1985 published the first paper on it, including proof of concept. Phreaking more generally is the process of exploiting telephone networks.

You could take your monitor to a professional to have it done, but doing it yourself is relatively quick and hassle-free and will greatly improve image quality. Manufacturers keep pumping out displays with new technologies like 4K UHD resolution, high dynamic range (HDR), and curved monitors, providing a veritable feast for the eyes — but only if they are properly calibrated.
The Lagom LCD Monitor Test Pages: Handy for both online and offline use, the Lagom LCD Monitor Test Pages not only allow you to adjust various things such as contrast and response time, but also allow you to download the images as a 120KB zip file, so you can check any monitor in-store that you are thinking about purchasing.
The best way to avoid this problem and ensure that you calibrate your monitor correctly is by purchasing a calibrating device. You’ll need to spend a decent amount of money for the best control and precision. Still, there are affordable alternatives to help you achieve consistent color across all of your monitors.
Accidental Damage is any damage due to an unintentional act that is not the direct result of a manufacturing defect or failure. Accidental damage is not covered under the standard warranty of the product. Such damage is often the result of a drop or an impact on the LCD screen or any other part of the product which may render the device non-functional. Such types of damage are only covered under an Accidental Damage service offering which is an optional add-on to the basic warranty of the product. Accidental Damage must not be confused with an occasional dead or stuck pixel on the LCD panel. For more information about dead or stuck pixels, see the Dell Display Pixel Guidelines.
No, accidental damage is covered for Dell computers or monitors which are covered under the Accidental Damage Service offering for that specific product.
The LCD glass on the display is manufactured to rigorous specifications and standards and will not typically crack or break on its own under normal use. In general, cracked, or broken glass is considered accidental damage and is not covered under the standard warranty.
Spots typically occur due to an external force hitting the screen causing damage to the LCD panel"s backlight assembly. While the top layer did not crack or break, the underlying area was compressed and damaged causing this effect.
If your Dell laptop LCD panel has any accidental damage but the laptop is not covered by the Accidental Damage service offering, contact Dell Technical Support for repair options.
Dell monitors cannot be repaired by an on-site field engineer or at the mail-in repair center. If you notice any damage to the monitor, you must purchase a new monitor.
