Having trouble with a ViewSonic VX2245wm

I recently bought a View Sonic Viewdock 22" DVI Monitor, and so far I'm very pleased, I'd be more so if it didn't have one bad quirk to it, on the lower left side of the screen the horizontal refresh seems to slow to the point that if I unfocus my eyes by blinking or panning up and down the screen, I can see diagnol "translucent" lines moving left . I'm curious as to weither this is the monitor, a glitch with ATi Drivers (I upgraded to the latest version to try and remedy the problem, but to no avail) at a high resolution (first time I've used anything above 1280x1024). Maybe it could be that coupled with the fact that I'm using dual LCD monitors, one is my 17" BenQ T705 on the Left side along with my Viewsonic. Anyone have any helpful advice or opinions they'd like to add? Anything helpful is very much appreciated. System Specifications below incase any of you are interested.
