I am having an issue all the time, gaming or just moving/resizing windows.

 

The issue is that every time I move something around my desktop (re-size a window, drag it across the desktop) or play any game where a scrolling situation is present, such as moving forward or panning camera up and down, a single horizontal seam appears. This seam doesn't split or rip, the picture stays continuous, but on either side of this “seam” it seems that the picture on either side of it are rendering at different rates. i.e. the pictures don't match up 100%. The vertical edges of a left-to-right dragged window do not line up.

 

Any help would be grateful. Also on my left display when a game is open in the centre I have ghosting. Not a huge deal though.

When did this issue start happening?  Was it after you installed/updated or otherwise changed something?

I wish I could pinpoint it. It MAY have started when I set up my eyefinity a little while back but I can't be sure. Jsut started noticing it yesterday. 

I had the previous catalyst then updated when i noticed, no change though.

Ooh, update, only happens on centre monitor which is connected direct using HDMI. Strange. 

 

UPDATE: SOrry, shoudl ahve done this in the first place. 

If I swap the HDMI from monitor 2 with the DVI-VGA from monitor 1 the ghosting follows the video card output but the seam seems to dissappear. Is there a reason I shouldn't use the HDMI as my centre monitor?

 

The seam also works its way gradually up from the bottom of the monitor tot eh top then starts at the bottom again. 

 

Also the colour scheme changes on monitor 1 when i change from DVI to HDMI, gets cloudy and low contrast it seems.
