    I recently flashed my Sapphire 4870 1gb card and haven't been able to get dual monitor support working in Mac OS. Has anyone been able to get this working on a Sapphire 4870?

    It works fine in Windows, not sure why it wont work in MacOS as I imagine the 10.5.7 drivers should be doing all the work.

    Netkas, is there a 4870 ROM (for XFX) that gives at least one working VGA without any software mod or a program like SwitchResX? You seem to be the expert here together with Rominator. I have tried to tweak my Samsung HDTV to run with DVI/HDMI but it is never as good as with VGA. But with one VGA my second output is dead.
