Hi there, I have 900p monitor (1440x900) and from driver control center I changed the resolution to 1920x1200 which is not supported from my monitor, so it's now black and says 'Frequency out of range' I can't see anything, what should I do? How can I change the resolution back to normal, I have Windows 10 and no other monitors to try on. Please respond, I can't do anything, HELP!
