So I took my computer to BestBuy and explained the problem in great detail but apparently they're idiots over there so I guess I'll see if maybe you guys can help me figure it out.
I play on a Dell Inspiron N5010, crappy laptop but it does the job. I hook it up to my AOC e2351F LED 23" monitor. Now, when I first did this, my resolution would go to 1920x1080p just fine. From one day to the next, out of the blue, it no longer allowed me to do this. The highest resolution I can go now is 1440x900 which is very frustrating. I have literally tried everything I could think of. I've even had the computer reset to factory settings (not joking). I noticed that if I change the refresh rate to 30Hz from 60Hz, then it does allow me to go to 1920x1080 again but obviously this isn't an option because at 30Hz the screen is flickering and shacking so violently it makes me sick.
The geniuses at GeekSquad told me that the problem is that my computer doesn't allow my monitor to reach its full potential. You can see how this would frustrate me when I specifically told them that IT USED TO ALLOW ME. Literally one night I woke up, got on my computer, and my resolution wouldn't go higher.
What would cause something like this and is there a fix?
I'm sorry if I didn't provide more information that I should have, I'm really not tech-savvy in the slightest.
Thanks in advance for any help.
