I have a Dell Dimension 4600 with a Radeon X1600/X1650 graphics card. I had two Dell monitors hooked up to it. One was the basic 19" flat panel, the other was a Dell 19" Ultra Sharp. I has a problem with the mouse jumping about 4 inches vertically when moving from one screen to the other. I played around with the settings and couldn't get it any better. Thought it was because the monitors were different (had the smae problem at work until I got two monitors that were exactly the same).
I wanted to upgrade my monitors anyway, and thought that would take care of the problem. I just purchased two new Samsung 23" 1920x1080 monitors, and still have the same problem!! The mouse moves vertically about 4" when moving from monitor to the other.
Does anyone have any ideas as to how I can correct this problem?
