My monitor is set for a display area of 640 X 480, I need to change it back to 800 X 600 but it will not go back. It has been set on the lower settings for a couple of years. Now I need to change it for certain software and websites. When I change it, it reverts back to 640 X 480 after a few seconds. I tried to change it after setting my color to 16 bit, but then I ended up having to go to safe mode as it was not possible to see anything on the screen at all. Does anyone (please) have any advice?
