I have had a new PC for the past 4 months, with a gtx 770 an i7 4770, using an Acer G246HL 60Hz at 1920x1080. I had been using it like this last night, however i came on today and it was at 1024x768 and there was no option for 1920x1080 on either the screen resolution page or nvidia control panel. I also noticed that in device managers my monitor name is not there and is recognized as general non PnP monitor. I have gotten drivers for the monitor and re-installed the drivers for the graphics card with no luck. Please any help would be fantastic at this point
