Soo i went to my Screen resolution and tried changing back but i wasnt there the highest was 2048x1536(that my monitor cant run), 1920x1440, 1920x1200. im runing it currently on 1920x1200 and after a brief time the monitor turns black and pops a box that says: Not optimum mode Recomended mode: 2048x1152 60Hz. Im running a Nvidia GeForce gtx 650, Generic Non-PnP Monitor. oh and btw when my pcs turrning on its res is 2048x1152
