Check the computer monitor cable
Loose-fitting monitor cables can also cause flickering. These loose cables will make your screen glow. To check, unplug the display cable and reconnect it securely. Do this on the back of the screen and on the computer.
Replace the display cable
Low quality display cables can also cause screen flickering issues. If you do not know which cable to use, the monitor guide will help you. This will include the types of cables your monitor supports.
Change the refresh rate of your screen
Your screen’s refresh rate is the number of times an image is refreshed on your screen per second. For example, a 60Hz screen will refresh the screen 60 times per second. With a higher refresh rate selected, your screen will likely have problems refreshing content at that rate.
How to change the renewal rate
Select the Start button and go to Settings > System > Display > Advanced display settings.
Under Renewal rate, select the rate you want.
The refresh rates that appear depend on your monitor and what it supports. Select laptops and external monitors will support higher upgrade rates.
