How To Know The Right Time To Replace Your Old Monitor

Having your PC monitor burnt out in the middle of work or binge-watching can be dreadful. 

You may be wondering how this could happen? After all, you always were very attentive about using your computer. 

As much as no one would ever like that to happen, every piece of technology has an expiry date. Even the most reliable computer store in your area or your online retailer cannot give you a lifelong guarantee. 

Knowing about the longevity of your monitor beforehand, therefore, can save you a lot of hassle. 

Most people do not bother until their devices break down. If you want to avoid this situation, then you need to know when it is the right time to get your monitor replaced.

What is the Longevity of PC Monitors?

So, you have checked the size, resolution, video inputs and warranty when buying your old monitor. One thing you have overlooked, though, is the longevity factor.

So how long does a PC monitor last anyway?

This depends a lot on the type of light source they use. There are three types:

  • LCD
  • LED
  • CRT

Among these, LED monitors tend to have the highest average lifespan. 

Ideally, monitors have a lifespan between 30,000 and 60,000 hours of use. That means they can last for up to 10 to 20 years despite being used constantly. 

That is, of course, if you run your monitor for eight hours a day. Use it for any longer, and the lifespan will decrease. 

Signs That You should replace your old Monitor

So, how do you know there is a problem with your monitor in the first place? 

Other than it going completely black, there are few signs to know your monitor has come to its end. 


A flickering or blurry display is the first sign of trouble. You may also notice some distortions in colour pixelated graphics. 

This happens due to the magnetic field present in the speaker systems.

Lines or spots

If you start noticing bright, white spots on the colourful area of the screen, then it can mean two things.

  • Either the screen has been damaged physically


All black

If this happens, first check if all the cables (VGA, DVI, HDMI, DisplayPort) are correctly connected. 

If the problem persists, then the backlight has probably burnt out. 

All of these are signs that you need a new monitor. 

Tips for Increased Monitor Life

If your monitor still has some life left in it, your local computer store may be able to help you even repair it. 

You should still have the mindset of not getting too attached to your old devices as you have to replace them someday. 

However, you can increase their lifespan with some maintenance tricks:

  • Always clean the area around the monitor to keep it tidy and free of dirt.
  • Do not put any liquid anywhere near your monitor. 

Also, if you want the best output from your computer screen, you can try using the recommended resolution. This will put less stress on your monitor and expand its life.


It can be challenging to have your PC monitor break down in the middle of work. To avoid this, always make sure to read the signs earlier, as mentioned above. 

That way, you can avoid any such situations by getting your old monitor replaced sooner.
