Can you please help me? I have an Acer K222HQL monitor that I was trying to overclock and now it just says "Input Not Supported". I have looked up a bunch of videos to try to fix this problem, but nothing work. One video said to hold down shift + F8. Another video said to spam F11 until a menu came up, but still nothing worked. I tried everything you said to do but again, nothing worked. I had watched a video on how to overclock a monitor. The guy said your monitor will go black but not to be worried because it would come back on after a while. First I tried putting it up to 80hz. Then 90hz, 120hz, back to 80hz, and then lastly 90hz. I don't know what I did wrong, but this time the monitor didn't come back on. I'm really panicking because I don't know what to do and I don't know if I broke my monitor or not. I'd greatly appreciate it if you could help me fix this problem.
