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.

  1. We had a new monitor installed at work. A day or so later it started blinking/flashing at different times of the day either fast or slow. Have followed some of the information above and would have changed the refresh rate. However since it is a work item the default is set to 66. So will have to contact our in-house IT dept again for this fault

  2. So if anyone is having this issue and finding the solutions here don’t fix their problem and you have an AMD setup. Turn off AMD Freesync!!! You are welcome in Advance!
