    Hi Everyone,

    Been working on a quartz composer video wall using a Mac Pro 1.1 Quad-Core, two flashed/windows ATI 5770s and five Samsung 1080p monitors. The problem is I can't seem to get more than two outputs per card. I've tried using the active Single Link DisplayPort (Not Mini DisplayPort, as they are flashed cards) to DVI adapters but still nothing.

    Has anyone tried running Three or more displays on a flashed 5770 and managed to get any output?

    Cheers :D


    Hardware:

    2 x Radeon HD 5770 1GB

    5 x Samsung SyncMaster 23.6"

    Sapphire Active Display Port to Single Link DVI Adaptor

    Mac Pro 1.1 Quad 2.66 GHz - 4GB RAM

    What OS?

    The flashed 5 series cards have issues with DP in various versions of OSX

    Also, I have found that Bizlink sells "active" adapters that are junk.
