Loose monitor cables can also cause flickering. These loose cables can cause your screen to flicker. To check, unplug the cable from your monitor and plug it back in properly. Do this on the back of the monitor and on the PC.

Change the refresh rate of your screen
The refresh rate of your display is the number of times per second that the image refreshes on the screen. For example, a 60Hz display will update the screen 60 times per second. It is possible that a higher refresh rate is selected and your monitor is having difficulty refreshing content at that rate.
How to change refresh rate
Select the Start button, then select Settings > System > Display > Advanced display settings.

The refresh rates that appear depend on your display and what it supports. Some laptops and external displays will support higher refresh rates.
