ATI HDMI refresh rate override?

[smalls102k7]

I currently have 3 tv's hooked up to my system. Two of them have a 60 refresh rate, but the third won't let me go higher than 30 and this looks bad/ rough on the eyes. Everything above 30 is italicized and if I select it, the screen goes blank and it says "invalid format." It says the maximum reported refresh rate is 70. Any suggestions? Thanks

try switching the monitors around and see if its the same one each time causing the problem, if it is you can point the finger and hardware issue, if its always say monitor 3 that has the locked refresh rate, it would point more towards software/driver issue.

I have switched the cables, but the same issue. Whenever I put in the higher refresh rate, the screen goes blank and in the corner it says "invalid format". I have thought about using powerstrip or another program similar, but don't 100% know what to change where. Thanks for that idea!
