I have an emachines monitor with a Dell computer. The monitor was just fine with the original emachines, but with the Dell, if I try to go to the resolution 640x480 or lower, all the screen fitting options go out of whack. Suddenly the top of the screen is wider than the bottom, the middle is too skinny, some of the screen is cut off, etc. I tried adjusting it with the monitor controls and nothing changes. Everything is fine on higher resolutions, but 640x480 or lower is screwed up. I need to be able to use 640x480 to play older games. My video card is a GeForce FX 5200. Any suggestions?
