I have built a custom PC and when plugging in a USB mouse I accidentally pressed the CMOS button on the motherboard port area. The monitor went off and after waiting I turned off the computer with power button. When I rebooted my bios was fine as I didn't change it in the first place and when got to my desktop the resolution was messed up. I have a Viewsonic 1080p Monitor and my system resolution on windows was 1080p and on nvidia interface the same ( I have a 560ti) I have tried to manually drag the nvidia options and can only get a good resolution on a odd resolution which is 1804 x 1014 but when i put it to full HD its stretched off the screen. With the current resolution the detail is fuzzy and I can't find any options on the monitor or in resolution setting which can solve this. Please help me in my hour of need.
