I Increased my monitor's refresh rate beyond its maximum setting.
I Increased my monitor's refresh rate beyond its maximum setting.
I’ve kept my monitor’s refresh rate overclocked. The original was 60hz, then I increased it to 75hz and it functioned properly. Recently, I attempted an even higher setting, and after reaching the maximum, the screen automatically restarts with a 20-second black screen when I try to go higher. It now displays “input not supported.” I’m unsure how to resolve this issue since I can’t access my computer. Please help me so I don’t have to replace it. Thanks for your time.
Can you access your BIOS settings? If so, the graphics driver might be configuring an unsupported mode at boot. You'll need to boot in safe mode to remove the driver and reinstall it. If you can't reach the BIOS, try resetting the monitor by disconnecting it from power for a few hours.
Yes, if you encountered a black screen, simply maintain the 75hz setting.
You don't perform that action via BIOS. There are multiple methods to reach recovery mode, most relying on starting in Windows. The most effective approach I've encountered is to let the system boot until the spinner stops, then halt before enhanced drivers load. Turn it off a few times and Windows will detect an issue and attempt to start in recovery. In recovery, select Safe Mode with default VGA drivers to prevent loading your card's video drivers, then uninstall them. Another option is using a Windows installation disc or USB to enter recovery mode—follow method #3 or use the recovery key #4 if available.

And if this seems complicated, consider using a friend's 144Hz monitor (just for safety) and adjust the refresh rate back to 75hz. This way, you avoid reinstalling drivers entirely.
