Hi,

My monitor was running 2560x1440p @ 165Hz for the past year. Today all of a sudden my pc changed my default resolution when I started up video games like League of Legends and Apex, I didn't think too much about it and updated the Nvidia drivers in case that was the problem. Now, my pc doesn't even have the 144/165 Hz options anymore only 60Hz. I am using a display port and it was working yesterday so the cable shouldn't be a problem. I'm able to get 165Hz at weird resolutions like 1920x1440. I went through Advanced display settings -> Display Adapter Properties -> Monitor and it still only shows 60Hz. I checked Nvidia Control Panel and that doesn't have it either. My PC is using the Ultra HD, HD, SD setting in Nvidia Control Panel. I read somewhere that I need to use the PC option but there is no 2560 x 1440 option at all, let alone 2560x1440 @ 165Hz. This was working yesterday so its not a compatibility issue, can someone help me out, Thanks!
