Problems with screen resolution

Hi all. I have problems with the extension of the screen at eight, one time I installed the driver for the GeForce GT 630 and everything was OK after a while began these problems after updating the driver I have changed the extension of the screen on 1024x768 and it was not possible to change to the right (1920x1080), in this case, I did a driver rollback and everything was falling into place. Today because of the glitch with the stim I had to do a system rollback, then the resolution has changed to 1024x768 and it doesn't change, I tried the version of the driver, dug in an Internet, read about what you can change via the registry, but all to no avail. Help who than can ples!!!
