Mac Pro Display Issue HELP!

Hello Everyone,

Lately i just bought a new mac pro. recently i have been doing some video projects in final cut pro 7 (i know its outdated lol) in the video preview it seems that the video has some distortion to it, meaning the the video has a skewed effect to it of some sort. I upgraded from a 2009 iMac which i have never noticed this issue before! I don't think that it would be a hardware issue.. heres my specs:

3.33GHz 6-core

12 gigs of ram

ATI radeon 5770 1gb ram

Monitor: Samsung SyncMaster SA300

I think that it may be the monitor.. as i soon plan on upgrading to a cinema display.

If anyone has and idea what may be causing this unusual issue that would be greatly appreciated!

Thanks in advance!
