Win 10 blurred resolution [Urgent]

I bought a new PC and my monitor is kinda old. In my prev PC I had graphics card Nvidia. Everything right now is blurred, every resolution. To fix that I need to set the resolution at 1680 X 1050 from both the PC and the graphics card's software. My old PC had Nvidia and I could do that easily but now when I have AMD card it seems like I can't change it from the AMD radeon settings. It's simply saying that my monitor is not good enough which is not true because I had that very resolution until now...

Everything is blurred and is hurting my eyes so it's kinda urgent. Thanks
