Why Is My Computer Monitor Heating Up?

A computer monitor is among the most important parts of your desktop computer. It is the part that gives you the full experience when gaming or browsing the internet.

However, these monitors overheat, and fixing them can be quite challenging, especially if you’re a beginner. It can take a lot of time to identify the issue, and repairs can cost you a fortune.

Symptom of an Overheating Monitor

It’s quite discouraging when your monitor keeps overheating. The first thing to do is calm yourself and ensure you’re safe. Unplug your monitor from power and ensure that you and the environment around the computer is safe. Give it time before trying to turn it on again. You can blow canned air inside the monitor casing to eliminate dust.

If the entire computer room is hot, it’s time to turn on your air conditioning to cool it down. Here are some possible overheating symptoms:

  • Too hot to touch: If you notice that your monitor is too hot to touch, you need to follow the tips above to save your hardware and software.
  • The monitor keeps turning off for no reason: If you’re using your monitor and it suddenly crashes down, this can be an indication that it’s overheating. After crashing, check the temperature; if it’s too high, leave the computer to cool down.
  • Lines of pixels on the screen: This can be caused by a problem with your graphics card or the monitor. Check if you’re overworking the graphics card and if it’s well-ventilated.

Although all electronics are prone to overheating, this can damage hardware and software. Most PCs come with components for heat dispersion and ventilation to prevent overheating.

If the monitor gets hot and the fans get loud, you may be doing intensive tasks like playing games, having several browser tabs open, or streaming videos online. If the monitor is hot but working fine, give it a break and close those apps for a while.

What causes monitors to overheat

A monitor that is heating up is a sign that there is something wrong with the device. It might be overheating because it’s not getting enough airflow, or there might be a problem with the internal components. If your monitor is constantly heating up, you should try to troubleshoot the issue and fix it as soon as possible to avoid damaging the device.

Here are some causes of overheating monitors.

Dust build-up

This is one of the leading causes of overheating because dust gets in everywhere without noticing. Most people don’t even know that dusting inside the computer prevents it from functioning properly. Interestingly, if cigarette ash gets in your computer, it can also slow down the performance.

To prevent dust build-up, buy canned air for electronics to remove dirt and dust from the inside of your computer.

Excessive heat

Excessive humidity and heat can also overheat your monitor, making it hard to cool down. However, these aren’t common and are extreme conditions. Water from the air can damage the internal components and destroy the monitor completely.

Blockage of the vents

The monitor comes with vents just like the computer case. There are usually narrow and are located on the side of the case. If they are blocked, blow canned air around them to clean them and clean the inside. Ensure there’s sufficient space around the vents, and nothing comes in their way.

How do I cool down my monitor?

If your monitor is heating up frequently, here’s how you can fix it and enjoy a smooth computing experience.

Turn off your computer and monitor

Switch off both your computer and monitor while cleaning the outer part of the monitor. This is also a good time to clean your computer to improve airflow for a cooler environment when processing and operating.

Clean the vents

Check if the air vents on your monitor are blocked. The vents are located on either side of the monitor but occasionally above the screen.

Use the PC vacuum

PC vacuum is specially designed to clean PC hardware. Attach the nozzle part of the vacuum and aim directly over the vents to eliminate debris and dust. Ensure you use PC vacuums and not the regular ones.

Adjust your power options

Go to your monitor’s settings and adjust the screen to switch off when it’s not in use. When the screen is off, it will have time to cool off before you resume. If you try these tricks and nothing works, you can consult a computer repair technician.
