You should connect your monitor to any other PC if the cable is fine. If the monitor works without issues on any other PC, the fault is within your PC. If the monitor doesn’t work with another PC, then there’s some issue with your monitor, not your PC. 

3. Disconnect All Other Accessories

The issue can also be caused by other accessories that you have connected to your PC. You must disconnect all other accessories from your PC individually and check if the issue is still encountered.
