Hi I recently restarted my PC and before doing that I could play games at 1440p at 60hz. After I restarted it cause it had some issues now I can only play at 1440p at 30hz. If I choose 4k or 1080p I can do 60hz but not on 1440p. It worked before so idk what I may have done or what.

I checked the modes and it shows 4k 60hz and 1080p 60hz there but still only showing 1440p for 30hz and 23hz. I wish I knew why it was working before and not now.
