How Long Do Computer Monitors Last? What Can You Do To Increase Their Lifetime?

How Long Do Computer Monitors Last?

Monitors are a very essential part of a computer setup and they are also expensive. So before buying a monitor for your PC, you should know “How long do computer monitors last?

In this article, we will give answers to all the questions related to the lifespan of a monitor and the things you should do to keep your monitor in the best condition.

Finally, we will also provide some useful advice on how to properly maintain your monitor and extend its lifespan.

How Long Do Computer Monitors Last?

The typical lifespan of a standard computer display is between 30,000 and 60,000 hours. This equates to 10 to 20 years of regular use, considering you are using a monitor for about eight hours a day.

However, some monitors may last longer and shorter depending on various factors like maintenance, usage, and the quality of their materials.

Factors That Affect The Lifespan of a Monitor

The lifespan of a monitor is affected by a number of factors. Not all screens are made equal, and these subtle variations will determine whether they last or break.

Components Quality

The total lifespan of a monitor is often increased by using strong, reliable, and high-tech components. If your monitor is built with state-of-the-art technology and utilizes top-notch electrical components then it can be easily said that it will give you a quality service for a long time.

The quality of the components is so much important that it can substantially increase or reduce the service life of a monitor.


Your monitor’s lifespan may be impacted by the level of maintenance and care you provide it. Try to use a microfiber cloth to clean your display on a regular basis. Prevent smoke and other possibly dangerous fumes come near your monitor and also avoid dampness.

In the first few years after purchasing the display, if you experience any problems, be sure to get it fixed right away. If any specific component of your monitor gets damaged then you can also buy it individually.

Duration of Use

We all know that if a device or a machine is used moderately then its service life will be long. On the other hand, if it is used excessively then its service life will definitely get reduced.

The longevity estimation of 10 to 20 years, or 30,000 to 60,000 hours, is based on the assumption that users engage with their screens for about eight hours each day. If you use your monitor more frequently which is more than 8 hours every day then its overall life will decrease.

Another important matter is how you are using it. For example, if you always use your monitor at full brightness level then it’ll definitely harm your monitor and due to this its life will decrease.

Brand and Model

Your monitor’s lifespan will also depend on the model and manufacturer. Generally speaking, monitors from well-known brands last for a longer time than those from lesser-known manufacturers.

In addition, certain models are created with longevity in mind, making them more lasting than others.

How Can I Extend My Monitor’s Service Life?

Here are some things which you should do to get the most out of your monitor.

Keep Your Monitor Neat and Clean

Although it might seem like common sense, many individuals neglect to properly care for their monitors.

Your screen will inevitably become covered with bacteria, particles, and dust and an accumulation of just one of these might create disruption in the internal components of your monitor. Make sure to thoroughly and frequently clean your monitor to avoid this.

Another important thing is to always keep your area of work neat and clean. Do not keep any liquid items around your monitor to prevent accidents

Keep Air Vents Clear

Solid-state electrical components are used in the construction of the latest computer monitors. They overheat when overused. That’s why most monitors have several air vents, which help prevent overheating, but objects in your workspace can easily obstruct them.

That’s why it should always be kept in check that those air vents do not get blocked by anything or if dirt gets accumulated there then they should be regularly cleaned.

Maintain a Medium Brightness Level

High screen brightness not only harms your eyes but also harms the computer’s mechanics.

Full-beam screens will wear out significantly more quickly than screens with a modest level of brightness. In order to preserve the interior bulbs, reduce the level to the middle point or lower.

Employ a Surge Protector

The lifespan of your monitor screen could be considerably increased by installing a surge protector. Your monitor will be subjected to daily electrical current fluctuations if it is plugged straight into a wall-based power source.

Through their fundamental nature, surge protectors shield delicate electronics from those erratic currents.

Screen Saver Should Be Set to Solid Black

Make sure to use a plain black screen saver for your computer rather than one with a more complex and bright design. By doing this, power will be saved and the LCD lights on the screen will live longer. Moreover, this process might lessen the burn-in impact.

Be as Conservative as Possible When Using

If possible, avoid using your monitor for more than eight hours every day.  In the long term, this will increase its lifetime.

When not in use, it’s essential that you switch your monitor off at the mains. Due to this, the power supply will stay in good shape and avoid burning out.

Lifespan of Different Types of Monitors

There are different types of monitors now. The lifespan of every type is different from the others.

Cathode Ray Tube (CRT) Monitors

The lifespan of a cathode-ray tube monitor is between 20,000 to 30,000 hours. This time frame implies that your CRT display will function well for up to 10 years. It will last for this amount of time if you operate the monitor for eight hours per day.

Due to the use of inefficient cathode-ray tubes, the CRT panel has a shorter life. In addition, these displays are heavy and feature weak, fragile components.

Liquid Crystal Display (LCD) Monitors

LCD monitors often have a longer lifespan than CRT monitors. The lifespan of a standard LCD monitor ranges from 30,000 to 60,000 hours, based on the frequency of use and maintenance habits.

It equates to 10 to 20 years of continuous use, assuming you are using the screen eight hours each day. Because of this, they are perfect for use as security camera monitors among many other things.

The strong, long-lasting parts and usage of more sophisticated technology are the causes of the increased lifespan of LCD monitors. To emit light, a liquid crystal solution in a polarized substance is used in this monitor.

If you observe a decrease in brightness, display fading at the screen’s edges, or a yellowish tinge to the backlight, your LCD display has probably reached the end of its useful life.

LED Monitors

Compared to a CRT or LCD monitor, an LED monitor has a longer lifespan. Its lifespan ranges from 80,000 to 120,000 hours of continuous use.

If you operate it for eight hours each day, this time frame corresponds to 30 to 40 years.

LED monitors’ ability to provide bright, energy-efficient displays is what gives them such a long lifespan.

OLED Monitors

According to a number of studies and tests, an OLED monitor may operate continuously for 100,000 hours. According to this lifespan, an OLED monitor may last 35 years with 8 hours of daily use.

Actually, the lifespan depends on how much you are using it. If you use it for longer hours then the lifespan will decrease. If you use it in harsh conditions then it will further add to the reduction of the lifespan.

Signs That Your Monitor Needs to be Replaced

A monitor will ultimately need to be replaced, even with careful upkeep and care. Here are a few indicators that it’s time to get a new monitor:

Dead Pixels

A monitor screen is at a dead end when it has dead pixels. If you notice black spots on your monitor’s screen, it may be due to dead pixels. This can indicate that it’s time to replace the screen because it’s wearing out.

Be aware that if you don’t replace this screen right away, your display could develop other serious problems.

Unstable Display

If the monitor you are using frequently turns on and off, occasionally goes into hibernation, wakes up suddenly, or otherwise behaves in a way that prevents it from displaying images on the screen then it indicates the monitor’s power supply may be malfunctioning.

To fix this problem, you must replace your monitor’s power supply unit.


Your monitor could occasionally show some unexpected images on the screen if it has a burn-in. Burn-in occurs when an image is displayed on a monitor for an extended period, causing a ghost image to appear even when the image is no longer being displayed.

By adding a screensaver at the precise moment the visuals appear, you can solve the burn-in problem. Software like JScreenFix is also an option.

Defective Screen

Images and graphics cannot be seen on a faulty screen display. Instead, a blue screen appears when it powers on.

This issue should not be confused with the black screen. If the screen is black then it indicates that a power supply problem exists.

A greenish display might also be a sign of a defective screen. When this occurs, the software and the hardware of your screen are damaged.

How to Check a Malfunctioning Monitor

Now if you got the answer of the question “How long do computer monitors last?” then we will now see what will you do to check a malfunctioning monitor.

Here are some steps that you can take to test your monitor and repair it.

1. Check the Connections

Initially, confirm that a functioning computer is connected to your monitor. Normally, you’ll have to turn on both your computer and monitor.

To do the tests, you might need to plug your display into a functional computer.

This is a simple repair if the image on your monitor is the same as it would be on another computer.

You’ll need to plug the monitor into a power source if you’re still unable to see anything on the screen.

2. Check the Electric Supply

A monitor may occasionally display nothing at all due to a loose electrical supply.

If the monitor is not turning on then check the connection. In some cases, though the connection is tight but still the monitor won’t get power due to a technical problem with the electric supply. In that case, try to connect the monitor to a different power supply and see whether it is turning on or not.

3. Power cycle operations

For the majority of the time, this would assist to fix general problems.

The power cycle is done in the following way

  • At first turn the monitor off. Then remove the plug from the power source,
  • Leave it unplugged for 15 minutes,
  • Then, reconnect the power cord to the socket after which you can switch on the monitor.

If all the techniques mentioned above fail then take your monitor to an expert and if the expert fails to fix it then it’s time that you should buy a new monitor.


I think now you have got the answer to your question “How long do computer monitors last?” Now you can understand that it depends on many factors like the price, model, manufacturer, care, maintenance, usage, etc.

I hope this post has been informative to you.
