For the past couple weeks, my monitor has been going completely white if I leave the computer alone for a few hours. If I spend a couple minutes turning it off and on, and moving the moue (not sure if that actually does anything), the screen eventually returns to normal. Once its operating again, there are no more problems, until I leave it for a few hours again. The monitor is only a year old, so I didn't think it should be having problems this quickly.
Does anyone know what the issue might be? is it fixable, or do I need to get a new monitor?
