Your Windows 10 PC monitor may flicker for various reasons. If you are unsure of the exact cause, try these classic solutions to troubleshoot and fix the problem whether you are using a laptop or desktop.
Reseat a loose monitor cable
Monitor cables may be loose if they were not inserted correctly the first time. These improperly connected cables can cause your screen to flicker. They can even loosen over time if they haven’t been plugged in securely enough.
To check for this problem, unplug the cable from your monitor and reconnect it securely to the back of the monitor and to the PC. Make sure the cable is tight and does not appear to move.
This applies to all types of cables, which can come loose for various reasons. You don’t necessarily need to know what type of cable you are using to perform this simple operation.
Replace your monitor cable
Poor quality cables are a common cause of screen flickering issues.
If you find that the cable is damaged, or if you have a cheap one, buy a high quality cable and use it with your display. By high quality we mean a cable that is either from the manufacturer of your monitor or from a third-party manufacturer with good reviews (most sites, like Amazon, post reviews for every product).
Your monitor’s user manual lists the types of cables supported by the monitor. More often than not, a monitor will support multiple types of cables, meaning if your current cable is an HDMI cable, the next could be a DisplayPort cable. They all work pretty much the same.
Just make sure your PC supports the type of cable you purchase for your display (the cable type name should be under each port on the back of your PC).
This will fix any cable related issues including screen flickering (if the issue is caused by the cable).
