How to Test a Computer Monitor

Monitors are delicate, and like other electronic gadgets, they do not build to last a lifetime.

1) Flickering

The thing is, all monitors flicker. They demonstrate visuals by rapidly flashing graphics on the screen multiple times per second.

However, this is frequently so rapid that the human eye misses it and is exceedingly faint even for the most eagle-eyed individuals.

If you see substantial flickering on your monitor, your operating system may have an incorrect refresh rate configured. 

A burned-out monitor can trigger flickering; however, the display does not have to be damaged. In rare instances, it also signals a power supply malfunction.

It also occurs due to improper contact between the wires and the display connectors infrequently. Another possibility is that capacitors swell from time to time.

If the flickering continues, connect the monitor to a different machine and test it. If the issue persists, it is almost certainly an indicator of a deteriorating monitor, and you should seek repair.


If you’re having trouble with flickering, you should upgrade your video card driver. If the issue continues, you can resolve the flickering by examining and upgrading your video card.

Additionally, inspect the monitor’s connection to ensure it is secure. If not, you can resolve the issue by removing and reconnecting it.

2) Take a Long Time to Awaken

The wake-up time of your display is the amount of time it takes to produce an image when you turn on your computer.

Apart from specific older CRT displays, all modern LCD and LED monitors take approximately 5-10 seconds to appear on screen after pressing the power button.

If any of the monitor’s internal components fail, the backlights will require longer than usual to appear on the screen. It is one of the signs that your monitor is nearing the end of its life.


Long boot times are a prevalent issue with monitors as they age. It could be a sign of faulty capacitors. Replace the capacitor to resolve this issue.

If you cannot do so on your own, get professional assistance or bring it to a repair shop. Having a professional assist you in replacing it is the best course of action to avoid causing additional harm to your display.

3) Dim Images

Dimming is a term that refers to a display that does not maintain a steady brightness over time, causing images to appear darker and less expressive.

If you notice that the pictures on the screen are significantly darker than it usually is, you must take action.

A monitor with faint visuals can be distressing to work with and detrimental to the eyes’ health. It is because monitors are no longer capable of providing the brightness they formerly did.

Dimming happens mostly when the backlight in LCDs and LEDs fails, but in CRT monitors, the element cathode tube ray neglects to function due to the monitor’s lack of backlight panel technology.


If you believe the dimming of the monitor is due to insufficient power, you can resolve the issue by using a different power cable. Additionally, you can check if the power-saving and adaptive screen modes are activated. When these options are selected, your display is likely to dim.

4) Dead Pixels

A pixel is a “tiny dot” on the screen that alters the colour, and monitors include thousands of these pixels that operate in concert to produce images.

Dead pixels are a problem that occurs exclusively on LCD monitors. They define pixels that do not light up or trap in one colour.

While a few dead pixels have little impact on the rest of the monitor, having a black dot in the centre is simply annoying.

While monitor warranties typically cover no more than a specific proportion of dead pixels, if you are experiencing an abnormally high number of these, it could indicate malfunctioning hardware or poor manufacturing.


If your display has dead pixels, you can repair it. Dead pixels are difficult to repair since they are irreversibly lost.

Your best course of action in this situation is to invoke your warranty. Replacing it under the manufacturer’s warranty is the best and quickest way to resolve this issue.

5) Burned-In Images

Suppose your monitor constantly appears with identical pictures. In that case, these images may burn into the display—Monitor burn-in results in a dim view of the graphic, always visible on the screen.

Burn-in images have the potential to damage everything and are highly irritating. You may find that you cannot remove the burn-in from the screen.

While this does not obstruct your view of other images on display, it does serve as a distraction.


With screensavers and similar software, you can avoid burn-in. Once the monitor has developed burn-in, utilize a software solution such as JScreenFix, Online Monitor Test, or Kill dead pixel to resolve the issue by cycling the monitor’s pixels on and off or employing pattern displays. 

6) Vertical Streams

Vertical or flat stripes and strange colour patterns on the computer monitor indicate a hardware malfunction. This issue occurs when the graphic card or monitor’s screen panel fails, whether it is a 24 or 27-inch display.

Whether CRT or LCD/LED, whatever type of monitor you use may exhibit vertical lines. Typically, these lines appear in a single hue.

Although these lines could cause by a damaged video card or outdated drivers, the issue causes by a damaged screen panel.

Additionally, burning smells may emanate from the monitor, indicating an internal component failure.


Vertical lines produce by a hardware malfunction and a malfunctioning graphics card. You can resolve this by upgrading your graphic drivers.

Modify the screen resolution if the problem persists. If these instructions do not resolve the issue, visually inspect your monitor for apparent damage.

Check to see whether your HDMI cable is damaged, as this could result in an uneven image on your monitor. Contact a professional for assistance if you continue to notice vertical lines on the display after performing these instructions.

7) Unexpected Shutdown

Another indication of a failing monitor is that it will shut down unexpectedly in the middle of a computer operation while the CPU continues to work.

Monitors turn off owing to overheating or insufficient power supply. Perhaps CRT monitors from the past are more susceptible to heat than modern flat-panel displays.

The monitor may shut down automatically to protect internal components from harm in overheating. Additionally, malfunctions in the motherboard’s circuitry may result in random shutdowns. It signifies that your monitor is nearing the end of its useful life. 


When your monitor randomly shuts down, you know it’s failing. To avoid your monitor shutting down unexpectedly, you can set it to shut down automatically.

It is to avoid escalating the issue and causing damage to the monitor’s internal components. Then, turn on a fan or turn on the air – conditioning system to assist in cooling the room.

Eliminate any dust that could cause a blockage, resulting in overheating. Then, inspect for a loose cable. Try replacing them if a faulty graphics card or motherboard causes the issue. You should consult a computer expert concerning this step, as it may require special knowledge.

8) Distortion of Image

You can detect whether or not your monitor is dying by the image’s appearance on your screen. If you notice that the image distorts, the monitor may have a problem. For instance, you may see a colour shift in regions of the screen that are brighter than regular.

Additionally, photographs may appear blurry even after modifying the settings. Then this is a sure sign that your monitor is approaching the end of its useful life.


A defective monitor may exhibit distorted visuals. To resolve such issues, the first step is to restart the computer. Images may distort as a result of driver or video resolution difficulties. Therefore, verify that your video drivers are up to date. If the problem persists, check for a damaged or dangling cable.

Additionally, make sure to remove any magnetic equipment located near your monitor. It is because magnetic interference can result in distorted visuals.

Finally, link it to another computer. If the problem persists, there is a good chance that it is faulty. You can try a new cable or a different computer to resolve this issue.
