Lion Display problem.

Hi

I have just brought a new Mac Mini i5 2.3ghz and for some reason Native resolution does not work with the Apple 20" Studio display. I have done some testing to make sure it's not a hardware problem and it's not, I have checked my monitor with my old G4 Mac Mini and the monitor works fine at 1680x1050 @60Hz.

But get this, as soon as I hook up the monitor to my new Mac Mini dvi to HMDi and boot into Windows 7 the monitor works fine at it's Native resolution, if I then boot back to Lion the picture just brakes up with any kind of movement like mouse movement, window scrolling. But if a use a lower non native resolution like 1600x1000 the Apple Studio display work fine, so i'm thinking this must be a software problem, Right? I have put a video online for you to get an idea to what the problem looks like.

If anyone has any solution I would be very grateful because I have run out of ideas.

Cheers.

Must be, as I said before, I have tried this monitor running windows using the same Mac Mini and the apple monitor work fine.

 

Well if that was the case and it was a HDMI problem then you would get the same display problems in windows 7, wouldn't you, but the monitor works fine using bootcamp and Windows 7 so i'm thinking it's a Driver problem and not a Hardware problem?

 

Good point.

 

I have just tried a new MDP to Dvi and the monitor is still producing the same results. FFS.
