Possible Causes:

Outdated graphics card
Dust in the monitor

Incompatible Refresh Rate

What do you see on your monitor? It is mostly static images. But do you know that your computer is constantly drawing and erasing the image you see? This step, which is called refresh rate, is so quick that the naked eye cannot detect it. However, at times, when the number of times your image is redrawn per second is low (30Hz or so) – for reference, do know that a system is capable of changing the image 100 times per second. The low refresh rate causes flickering to your monitor.

Loose Wires

Have you ever seen what’s behind your monitor? It is mostly a jungle of thick cables. Your monitor is attached to the CPU with the help of a thick HDMI cable. If this wire gets bent or if it’s tangled, it causes certain problems, including the flickering of your monitor screen. Also, in some cases, the pins inside the head of the cable get clogged in the dust. It also causes problems in the display of the monitor screen.

Outdated Graphics Card

Your computer’s graphics card is responsible for the monitor’s output. When the card is not updated, it starts encountering performance issues. The reason why your monitor is flickering is the incompatible graphics card. Ensure that you have installed the drivers’ updates.

Dust in TheMonitor

Dust buildup in the monitor is often the cause of bad performance. If you are not cautious about the regular cleaning of your device, it is possible that your monitor may record the performance of screen flickering.
