Have a look at Monitor and Cables

Don’t consider your monitor faulty without having a closer look. Monitor blinking issue might be happening due to its the cables. Turn off your monitor and unplug the power cable and display cable like HDMI. Wait for some time and replug the cables properly and see if this works because halfway plugged cables often create issues.

If this doesn’t work, then it might possible that power, as well as display cable, one of them, is faulty. Try to replace the cable this might works.

Also, try to use another monitor and see if it blinks. If it does not, then the monitor itself is faulty, replace the monitor if it’s under warranty.

Set Monitor on Correct Refresh Rate

Monitor’s refresh rate does matter, it is like how your monitor presents the image per second. A normal monitor will provide you around a 60Hz refresh rate, but a gaming monitor will provide you around 166Hz and a goi up to 360Hz. High refresh rate monitors are somewhat expensive but 166Hz is the sweet spot.

If your monitor is set on the incorrect refresh rate then it will encounter monitor blinking issues. Let’s adjust the refresh rate correctly for our monitor.
