So I've recently noticed an odd problem when I'm playing games or watching video. If there is fast motion, there are trails of colors coming off of everything. It's a little hard to describe so I uploaded a video of it to youtube (pretty crappy quality, but you can still see the issue)
I have my 120hz Planar monitor connected to my Radeon HD 7950 with a dual link DVI cable. Does anybody have any ideas?

Have a look at the Catalyst Control Center -- see if your monitor is set correctly.
Fixed it, went into my monitor's settings and turned off overdrive. Not quite what you said, but you put me on the right track, thanks!
