I have Toshiba A-200 laptop. I was playing some games and when I returned to desktop background picture was in the center of screen and very small, possible 640*480. I have tried to resize it and stretch it but it stays the same. I have rebooted computer but even that did not help. Do you know how to fix this strange background issue?
Sometimes, when you exit games desktop resolution is not switched back to native resolution but it stays as a resolution in games. I think that his is you problem. Right Click on desktop, choose properties and then click on advanced tab. Change screen resolution to native, apply changes and get back to desktop. I think that your strange desktop background issue is solved.
