7 Most Common Signs of a Monitor Failure Explained.

Are you worried that your computer monitor is malfunctioning, but unsure of how to tell? If so, fortunately, there are some warning signs that will clue you in if your monitor is starting to fail!

In this post, I’ll explain the signs of monitor failure – visual clues which may indicate that your screen is deteriorating. I will give you the heads up on some of the most common symptoms of a dying monitor so that you can get yours fixed before it runs into more serious issues.

Don’t let these puzzling problems put a damper on your computing experience—read ahead to make sure you know exactly what’s happening inside your computer!

Common Signs of Monitor Failure

1. Does not turn on

If your monitor remains dark and unresponsive even when plugged into a power outlet, the issue might be linked to either an internal connection problem or its power supply. Fortunately, if you have a model with external power capabilities – it’s easy to switch out for a new one!

To accurately identify any potential issues before splurging on such replacement parts, employ different cables in testing the monitor too. That way we can ensure that whatever is causing the lack of functionality originates from within the actual device itself.

2. Image distortion

As the monitor starts to fail, this can produce distorted images, which can take on a specific color tint, such as a yellow or green hue that adjusting color parameters cannot eliminate.

In other cases, an image will be displayed with static distortion of solid color lines that interrupt the image on the screen. This may be due to an electronics failure, or an accumulation of magnetic particles in the electron gun of the CRT monitor.

3. Flickering image

Another common sign of monitor failure is when the display begins to flicker, even after adjusting the brightness and contrast settings. This can also be caused by a faulty connection or loose cables. In some cases, the flickering may be caused by a dying backlight, which is used to illuminate LCD displays.

In this scenario, try unplugging and replugging the cables until you find a secure connection that eliminates any flickering. If this does not resolve the issue, it is likely due to an internal hardware failure – then buying a replacement monitor may be your only option.

4. Dead pixels

Dead pixels (or stuck pixels) are the most common issue of a failing laptop monitor. These tiny spots on the screen fail to display any color, and they appear as black dots or lines. This can occur when certain PC components within the device become defective or damaged due to long-term usage.

Over the long run, they can grow in number and become more difficult to ignore. Fortunately, there are some simple ways to fix stuck pixels, such as massaging the spot with a damp cloth (with some pressure) or downloading special software to repair it.

Additionally, if you have designated warranty coverage on your device, you can contact the manufacturer to see if they can provide a replacement or service. Although some dead pixels may be repairable, it is generally recommended to invest in a new monitor instead of trying to repair the existing one.

5. Lagging response time

On older monitor models, the response time between input and output may become significantly delayed. This will cause a noticeable lag in how quickly images on the screen display.

If you notice your display taking longer to update than usual or if games are suddenly running slower than before, this could be an indicator of an issue with the monitor. You might need to consider replacing it with a newer model in order to restore your normal performance levels.

6. Fuzzy images

When a monitor is beginning to wear out, the display might become fuzzy or blurry. This may be due to discoloration in certain areas of the screen, as well as a lack of contrast between colors.

If this is the case, try adjusting the brightness and contrast settings first before replacing your entire device. This can give the monitor one last chance to revive itself before investing in a new one.

7. Strange Lines and Patterns

Occasionally a monitor will display lines or patterns that do not belong there. This could be anything from vertical stripes to sporadic shapes and icons. In this situation, the fault is most likely related to a hardware issue.

These strange apparitions can be caused by several issues, such as dust accumulation inside the device or an internal hardware defect. It is recommended that if you spot any abnormal lines on the screen, turn off your device immediately before more damage occurs.

Then contact your manufacturer to see what options are available in terms of repair services or a replacement monitor. This kind of fault should not be left for too long, as it can cause further damage and interference to other components within the device. The best course of action is to contact a qualified technician or repair service, or look into purchasing a new monitor.

Things to Know to Extend Monitor Life

To avoid having to replace a monitor too soon, be sure to keep it in well-ventilated areas and use proper anti-glare protection if needed. Additionally, you should also take regular breaks from using the monitor, such as at least 20 minutes after every two hours of usage. Finally, make sure your computer is equipped with up-to-date software and drivers for optimal performance.

By following these simple steps, you can help extend the life of your monitor and ensure that its performance remains consistent over time. With the right maintenance routine and a bit of extra care, you can easily save yourself some money in potential replacement parts.


1. What should I do if my monitor starts flickering?

If your monitor begins flickering, try unplugging and replugging the cables until you find a secure connection that eliminates any flickering. If this does not resolve the issue, it is likely due to an internal hardware failure – then buying a replacement monitor may be your only option.

How can I tell if my monitor is failing?

The most common signs of a failing monitor are dead pixels, lagging response time, fuzzy images and intermittent power supply. If you experience any of these issues, it might be time to consider replacing your device.

What is the main cause of monitor failure?

The main cause of monitor failure is due to long-term usage – certain components within the device can become defective or damaged, resulting in performance issues. To avoid this, be sure to keep your monitor in well-ventilated areas and use proper anti-glare protection when needed.

How often should I replace my monitor?

Your monitor should be replaced when it starts showing signs of failure, such as dead pixels, lagging response time, and fuzzy images. Additionally, you should also replace it every 3-4 years for optimal performance.

What to do when there is no response when computer is turned on?

If your computer does not respond when it is turned on, check the power cables and ensure that they are securely connected. It could also be due to a faulty power supply or other internal hardware issues. If the problem persists, you should consider getting a new monitor.


Monitor failure is a common problem for many computer users, and can be caused by a number of different issues. If you experience any signs of monitor failure, try making some minor adjustments first before replacing it entirely. Additionally, taking the proper steps to maintain your monitor will help ensure its longevity.

No matter what type of issue you may be experiencing with your monitor, it’s important to take action quickly before the problem worsens or leads to more costly damages. If you notice any of these signs – or any other strange behavior from your monitor – it’s important to act quickly to identify and resolve the issue before it becomes worse.

By following these tips, you should be able to extend the life of your current monitor and avoid unnecessary replacements in the future. With these tips in mind, hope you will be able to identify the source of the issue and make an informed decision about how to proceed.
