As the title says, I have a PG278QR which has overclock feature to push it to 165 hz, which did work previously, but for a few months it's not really been working.
I have 2 screens, one running 60 hz as a secondary screen, which I have had to unplug out of my gpu to be able to use 165 hz overclock, so I thought must be my gpu starting to age, which by the way was working just fine before. Few months go by I upgrade my computer, which now has 14900KF and 4080 Super in it, and STILL it does not seem to work. If I select the overclock option the screen reports "No displayport signal", if I reboot my computer the screen works fine, up until Windows log in screen which is when it will give me the same message. So I am going on a limb here and assume this is some Windows problem.
I have tried a different cable, which clearly isn't the issue since it seems to work on boot.
Any ideas?
