I have a 3 monitor setup (each monitor is exactly the same). Two videocards, each with one splitter (one DVI and one VGA). I have two monitors hooked up using DVI and the third is connected through the VGA connection. I am running Windows 7.

If I resize a window from one DVI monitor to the other, it's not a problem. It does so very smoothly. If I resize a window on the VGA monitor it is extremely choppy.

Why? It's not choppy on other machines with only VGA connections. Has anyone else noticed this?
