So when my laptop boots up at 800 x 600, instead of actually displaying the full screen (capable of 1600 x1200) it only displays in the middle of the screen!. When I put it at 1600 x 1200 the screen is actually completely filled, but at 800 x 600 only half is filled. Its hard to explain, but it looks similar to running a game in a window. Is my laptop video card fried?
