Monitor won't overclock to 75hz anymore? What happened?

mid2000s · October 10, 2019

My 60hz monitor used to overclock to 75hz with CRU and run fine. Today I randomly decided to check my display settings and I must've been back at 60hz ever since I updated my graphics drivers after DDU'ing them. I tried changing my refresh rate with a custom resolution on CRU but it wouldnt show up in my display settings.. weird. Then I tried changing my refresh rate in my AMD Radeon Settings and it worked, but I could only get to 66hz. After some research, someone recommended I patch my AMD Pixel clock here. I did that, and finally 75hz does show up in my display settings, and now I can save a custom resolution with 75hz in my AMD Radeon Settings, and I can achieve 69hz with AMD Radeon Settings with virtual super resolution and gpu scaling off, but when I try changing to 75hz in my display settings my monitor gives me an Out Of Range error.. with or without either VSR and gpu scaling on or both. The obvious answer is to rollback my GPU drivers until I find a version that works, but I'd rather check if anyone has any other solutions first.. I was running 75hz fine for months and I know this monitor is a bit old and overclocking a monitors refresh rate shortens its lifespan, but I'm not ready to chalk it up to technological deterioration just yet, I really have a feeling 75hz might still be possible.

So far I've patched my AMD Pixel Clock, made sure to use Automatic - LCD Standard Timing on CRU, and made sure to turn on GPU scaling and virtual super resolution on AMD Radeon Settings, does anyone else have any ideas? Asus VX238

Can any of the great people of LTT help?
