help Resolution Over Monitors Limits. Please Help

ChrisBoyyes · March 29, 2020

I accidentally changed my resolution in amd catalyst control and I got a black screen cause I put it over the screen limits. I tried booting it in safe mode and changing the resolution but nothing happened. I also tried hitting the f8 key to put it in low resolution mode but the f8 key did nothing. neither did the F12 one. Any help?

I am also on windows 7 if that helps.

PLEASE help me as I can't get the pc working and I need it

Usually, if it fails to reach said resolution, it will blackscreen and revert back to normal after a few seconds. Did you just reboot the moment it blackscreened without giving it time to do anything?
You can plug in a different monitor/tv... Or change the display output on the GPU to a different port. Like go from HDMI1 to HDMI2. Sometimes that may work.

Is safe mode working at all? Can you see or access the bios? Or is the screen black all the time?

I waited the time it gived and I waited for about a minute. For some reason it didn't revert back. I don't really have a different monitor I only have the TV in my living room and the computer hasn't been unplugged for 10+years. It's a jumple of cables behind the desk. I would do it as a final option but not right now. Also the screen works in safe mode, I just can't change the resolution back to normal(I can't open amd catalyst control in safe mode) I can access the bios but I haven't tried tampering with it for now.

Thank you.

Forget it, I was just pressing the f8 key wrong for 12 hours

So... it works now?

Otherwise I would've recommended to just use DDU (display driver uninstaller) in safe mode, since you've mentioned that safe mode worked.

Yeah lol I was pressing f8 right as it booted which brought up a screen which displayed my hard drive and some other stuff and told me which one it should boot from. Apparently that was the option from the bios but I started pressing f8 after the boot screen which put me in the advanced boot options and let me choose low resolution mode. Thanks for all the help you gave me but it was just me being stupid
