    I have a Macpro1,1 with a flashed Powercolor HD5770 card. I currently run 3 displays off of it:

    1) DVI -> VGA (so that I get the boot screen)
    2) DVI -> DVI
    3) DP -> active dual link adapter -> DVI

    This runs great on 10.6.7 but in 10.6.8 and 10.7.0 Lion, Apple changed something that caused my DP output to stop working. So I am stuck at 10.6.7 at the moment.

    My question is... is there anyone running the official Apple 5770 in a Macpro1,1 that is running 3 displays in Lion? I don't want to invest in the Apple 5770 if it will not get me 3 displays in the end.

    Be patient and keep your wallet in your pants a little longer.

    Netkas reports that 11c37 beta of 10.7.2 carries fix for this issue.
