Hey guys,
Like the title says, I want to run my 3 x 27" Cinema Displays with my Mac Pro 6 core 2010 model. I've currently got the 5870 that was ordered when I bought the machine when they were refreshed back in 2010. I'm plugging in 2 monitors directly into the card using mini-displayport. Since the 3rd port on the card is a Dual Link DVI, I've got an Atlona DP400 which is a DL DVI > MDP adapter. It works perfectly in OS X and I get the full resolution of my monitor using it. However, in Windows, the monitor only goes up to a maximum resolution of 720P (1280x720). I know this is a common problem using the 5XXX cards and this adapter in Windows, but I was looking for a solution that would give me at least 1080P in Windows (1920x1080).
I came across this card (http://www.gefen.com/kvm/dproduct.jsp?prod_id=9898) which claims to have "An EDID switch button is provided for manually selecting the three EDID modes: 2560x1600, 2560x1440, or pass-through.". I can't seem to find anyone thats tried it with a Mac Pro and Windows, so I'm not sure if it'll have the same problem as the Atlona Card.
Would there be any other ways to get all 3 monitors running in both OS X and Windows (at least 1080P in Windows, and full res in OS X)? Has anyone tried the Atlona adapter with an AMD 6870, since the problem might be with the 5XXX cards only?
I'd really appreciate any help you could provide. Thanks!
