I cannot change the Setting to 1024x768 pixel. Can someone help solve this?

I just reformatted a new hard drive & installed MS XP Pro. The pixel setting is now 800x600. When I move the slide rule to minimize the size and enter "Apply," the screen goes black & I get a notice that reads, "Input Not Supported." I can't reduce the images & text to more manageable size.... show more I just reformatted a new hard drive & installed MS XP Pro. The pixel setting is now 800x600.
