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.

Sometimes, you"re working on something private in an open office, or browsing certain *cough* sites *cough* at home. You can"t have your colleagues or kids see what"s on the screen. To keep snooping eyes at bay, make a "your-eyes-only" monitor from an old one.

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.

If you have the space available, the best thing you can do with an extra monitor is to boost your productivity with a dual-monitor setup. A second monitor has many potential purposes, such as extended screen space, a dashboard for your social media or news updates, or a dedicated video conferencing screen.

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.

Make it a dedicated screen for Nintendo Wii:The Nintendo Wii can connect to a VGA monitor, so if you don"t have a Wii, buy one. In fact, buy a used one, they"re pretty cheap on Craigslist.

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.

Sometimes you might turn on your PC but your monitor displays "No Signal" on the screen. In this article, we will look at various solutions for solving this problem.

Before this step, make sure your PC has not gone into sleep mode or hibernated. If this happens, the monitor may assume the PC is off and will display "No Signal".Unplug power cable and VGA connector.

I"m using 2x identical Samsung monitors, a custom built desktop unit and a lenovo laptop (no docking station). The lenovo laptop has a minidisplay port and a vga port. Both of the computers go through a dual screen video switch, which allows me to switch between both computers while still using both monitors on each.

When I switch to the laptop, the monitor plugged through VGA (VGA -> Switch -> VGA) gets a slight blur, which is pretty aggrivating when you"re typing, reading, etc.

The problem never happens to the other monitor AND, more importantly, also doesn"t happen to that same monitor when I switch to my desktop, which sends its output through DVI (DVI -> Switch -> VGA),

Initially, I realized that when switching to the laptop, Windows discovered the monitors differently (one had a factory name, and one just was recognized as a Generic monitor). I saw that along with those discovery settings, the frequency was different (60Hz on the correct output, 59 on the other one). So I set the second one to 60Hz and that seemed to fix the problem temporarily. A few days later, the problem showed up again and this time the frequency was still correct, sitting at 60Hz. So I ended up getting a correct picture again by doing a new discovery run by clicking on "Detect" (when both screens go black for a second and then the display comes back).

This is a very weird bug, possibly in the display output/drivers/hardware etc of the laptop, which I can"t control anyways cause it"s a company laptop. All I know is, a straight up dicovery run doesn"t always thoroughly discover, and so to do the trick, I unplugg the VGA output, hit "Detect" again, and then plugg the VGA cable again. That seems to force the "deep" discovery and fix my problem temporarily.

If you’ve ever begun searching for a new computer screen, chances are you’ve probably come across the term IPS. It’s at this point that you may be asking yourself, what is an IPS monitor? And how do I know if an IPS monitor is right for me?

Below we’ll take a look at how IPS, TN, and VA monitors affect screen performance and do some handy summaries of strengths, weaknesses, and best-case uses for each type of panel technology.

With regard to gaming, some criticisms IPS monitors include more visible motion blur coming as a result of slower response times, however the impact of motion blur will vary from user to user. In fact, mixed opinions about the “drawbacks” of IPS monitor for gaming can be found all across the web. Take this excerpt from one gaming technology writer for example: “As for pixel response, opinions vary. I personally think IPS panels are quick enough for almost all gaming. If your gaming life is absolutely and exclusively about hair-trigger shooters, OK, you’ll want the fastest response, lowest latency LCD monitor. And that means TN. For the rest of us, and certainly for those who place even a modicum of importance on the visual spectacle of games, I reckon IPS is clearly the best panel technology.” Read the full article here.

TN monitors, or “Twisted Nematic” monitors, are the oldest LCD panel types around. TN panels cost less than their IPS and VA counterparts and are a popular mainstream display technology for desktop and laptop displays.

Despite their lower perceived value, TN-based displays are the panel type preferred by competitive gamers. The reason for this is because TN panels can achieve a rapid response time and the fastest refresh rates on the market (like this 240Hz eSports monitor). To this effect, TN monitors are able to reduce blurring and screen tearing in fast-paced games when compared to an IPS or VA panel.

In fact, TN monitor can sometimes be easily identified by the color distortion and contrast shifting that’s visible at the edges of the screen. As screen sizes increase, this issue becomes even more apparent as reduced color performance can even begin to be seen when viewing the screen from a dead-center position.

These high-end VA-type monitors rival IPS monitors as the best panel technology for professional-level color-critical applications. One of the standout features of VA technology is that it is particularly good at blocking light from the backlight when it’s not needed. This enables VA panels to display deeper blacks and static contrast ratios of up to several times higher than the other LCD technologies. The benefit of this is that VA monitors with high contrast ratios can deliver intense blacks and richer colors.

There is another type of panel technology that differs from the monitor types discussed above and that is OLED or “Organic Light Emitting Diode” technology. OLEDs differ from LCDs because they use positively/negatively charged ions to light up every pixel individually, while LCDs use a backlight, which can create an unwanted glow. OLEDs avoid screen glow (and create darker blacks) by not using a backlight. One of the drawbacks of OLED technology is that it is usually pricier than any of the other types of technology explained.

When it comes to choosing the right LCD panel technology, there is no single right answer. Each of the three primary technologies offers distinct strengths and weaknesses. Looking at different features and specs helps you identify which monitor best fits your needs.

LCD or “Liquid Crystal Display” is a type of monitor panel that embraces thin layers of liquid crystals sandwiched between two layers of filters and electrodes.

While CRT monitors used to fire electrons against glass surfaces, LCD monitors operate using backlights and liquid crystals. The LCD panel is a flat sheet of material that contains layers of filters, glass, electrodes, liquid crystals, and a backlight. Polarized light (meaning only half of it shines through) is directed towards a rectangular grid of liquid crystals and beamed through.

Note: When searching for monitors you can be sure to come across the term “LED Panel” at some point or another. An LED panel is an LCD screen with an LED – (Light Emitting Diode) – backlight. LEDs provide a brighter light source while using much less energy. They also have the ability to produce white color, in addition to traditional RGB color, and are the panel type used in HDR monitors.

Early LCD panels used passive-matrix technology and were criticized for blurry imagery. The reason for this is because quick image changes require liquid crystals to change phase quickly and passive matrix technology was limited in terms of how quickly liquid crystals could change phase.

Thanks to active-matrix technology, LCD monitor panels were able to change images very quickly and the technology began being used by newer LCD panels.

The VGA) connector is a standard connector used for computer video output. Originating with the 1987 IBM PS/2 and its VGA graphics system, the 15-pin connector went on to become ubiquitous on PCs,high-definition television sets.

Devices continue to be manufactured with VGA connectors, although newer digital interfaces such as DVI, HDMI and DisplayPort are increasingly displacing VGA, and many modern computers and other devices do not include it.

All VGA connectors carry analog RGBHV (red, green, blue, horizontal sync, vertical sync) video signals. Modern connectors also include VESA DDC pins, for identifying attached display devices.

The VGA interface includes no affordances for hot swapping, the ability to connect or disconnect the output device during operation, although in practice this can be done and usually does not cause damage to the hardware or other problems. The VESA DDC specification does however include a standard for hot-swapping.

In the original IBM VGA implementation, refresh rates were limited to two vertical (60 and 70 Hz) and three horizontal frequencies, all of which were communicated to the monitor using combinations of different polarity H and V sync signals.: 100

In order to advertise display capabilities VESA has introduced a scheme to redefining VGA connector pins 9, 12, and 15 as a serial bus for a Display Data Channel (DDC).

The same VGA cable can be used with a variety of supported VGA resolutions, ranging from 320×400px @70 Hz, or 320×480px @60 Hz (12.6 MHz of signal bandwidth) to 1280×1024px (SXGA) @85 Hz (160 MHz) and up to 2048×1536px (QXGA) @85 Hz (388 MHz).

While shorter VGA cables are less likely to introduce significant signal degradation, good-quality cable should not suffer from signal crosstalk (whereby signals in one wire induce unwanted currents in adjacent wires) even at greater lengths.

Some laptops and other portable devices use a two-row mini-VGA connector that is much smaller than the three-row DE-15 connector, as well as five separate BNC connectors.

Various adapters can be purchased to convert VGA to other connector types. One common variety is a DVI to VGA adapter, which is possible because many DVI interfaces also carry VGA-compatible analog signals. Adapting from HDMI to VGA directly is not possible because HDMI includes no analog signal.

For conversions to and from digital formats like HDMI or DVI-D, a scan converter is required. VGA outputs to interfaces with different signaling, more complex converters may be used. Most of them need an external power source to operate and are inherently lossy. However, many modern displays are still made with multiple inputs including VGA, in which case adapters are not necessary.

VGA can also be adapted to SCART in some cases, because the signals are electrically compatible if the correct sync rates are set by the host PC. Many modern graphics adapters can modify their signal in software, including refresh rate, sync length, polarity and number of blank lines. Particular issues include interlace support and the use of the resolution 720×576 in PAL countries. Under these restrictive conditions, a simple circuit to combine the VGA separate synchronization signals into SCART composite sync may suffice.

A VGA extender is an electronic device that increases the signal strength from a VGA port, most often from a computer. They are often used in schools, businesses, and homes when multiple monitors are being run off one VGA port, or if the cable between the monitor and the computer will be excessively long (often pictures appear blurry or have minor artifacts if the cable runs too far without an extender). VGA extenders are sometimes called VGA boosters.

The terminology here is sometimes used rather interchangeably when it comes to labelling various types of VGA cable and can be a little vague. However, the basic or standard VGA connector type will usually be referred to as some variant of the following: DE-15, HD15, VGA plug, SVGA plug, D-Sub 15 or D-Subminiature, or the more generic RGB connector.

Compared to older displays, LCD monitors are an excellent low-cost, low-power solution to our need for a computer display. Unfortunately, some monitor settings can make an LCD screen appear to flicker.

A flickering LCD monitor is more than just an annoyance. It can cause eye strain, headaches, and a host of other ailments, especially if you spend a great deal of time in front of your computer. Luckily, there are some steps you can take to stop the flickering and avoid these problems. In this article, I’ll show you how to stop your LCD monitor from flickering.

Although your computer monitor may appear to be a still image when no one is using it, it is actually being updated constantly. Much like a film strip is just a bunch of static images displayed quickly, your monitor updates at a fast rate to make it look like things are moving smoothly on the screen.

If the refresh rate on your LCD monitor is set too low, it can appear to be flickering since there aren’t enough updates per second. While some people are comfortable with around 30 Hertz, others can see the flickering and require a higher refresh rate. The most common refresh rate is 60 Hertz.

The refresh rates that you can set for your LCD monitor are largely determined by the capabilities of your monitor. While some LCD monitors can take advantage of several different refresh rates, others are confined to just one or two.

To choose a new refresh rate for your LCD monitor in Windows, begin by clicking on Start > Control Panel > Appearance and Personalization > Display. If you are on Windows 8 or 10, just right-click on the Start button and choose Control Panel. If you’re in icon view, you can click directly on Display.

Click on the Monitor tab and you will notice a few things. First, notice the setting labeledScreen Refresh Rate. This is the current refresh rate for your LCD monitor. Click the drop down menu and Windows will display all of the refresh rates possible for your monitor.

It is likely that your monitor can only use one or two refresh rates, so this list may not be long. Some manufacturers build monitors that can display anywhere from 30 Hertz to 200 Hertz. Normally, monitors with higher refresh rates will be more expensive. A common refresh rate for gaming monitors is 144 Hertz. If the price of a monitor seems too cheap to you, it’s probably because it has a low refresh rate. For example, some new 4K monitors are cheap, but are only 30 Hertz, which can make everything look choppy on the screen.

First, make sure you are using the latest driver for your LCD monitor. If the driver is outdated or Windows is using a generic driver, the number of refresh rates available may be limited. Visit the manufacturer website and download the latest driver for your version of Windows.

If changing the refresh rate doesn’t fix the flicker on the screen, it could be related to other factors. Here is a list of other items you should check:

Input Port – Another solution is to use a different port on the monitor, if possible. For example, if you are connecting using HDMI, try DVI or DisplayPort or VGA instead and see if that fixes the problem.

Surroundings – In addition to hardware issues, electromagnetic fields can also cause screen flickering problems. If you have something else plugged into the same power strip like a heater, fan, etc., try removing it.

Video card – If there is an issue with your video card, it will obviously effect the output on the screen. Update the drivers and open your computer to ensure that the video card is properly seated in the slot.
