I am suprised you havent checked that out allready! I looked into it briefly some months ago. I dont recall the reason, but I recall coming to the conclusion that it was not a probable fix. I dont think it lets you get super specific on refresh rate maybe.. ie 59.94 instead of 60. Since the problem seems very sensitive to even the smallest change in this area I figured it was not a solid solution I think? Something like that.. like I said its been a good bit. I do understand the graphics card>monitor thing. I have not found any good solution to clearing up the hiccups when taking video in from AS cards and spitting it back out.... similar to the problem posted here when converting to sdi... Always get some level of glitching... some more offensive than others but none really acceptable.
