    I bought a PC PowerColor 5770 video card of ebay that was flashed to work with the Mac Pro 1,1 (2006).

    While it DOES indeed work, the one flaw is that the system ALWAYS detects TWO monitors connected.

    I have reset the NVRAM, plugged in my monitor via a VGA to DVI adapter, and plugged the monitor in right to the DVI port, but it still detects TWO monitors.

    I was wondering if anyone might be able to help me out with a way to correct this, or point me to a new Bios/Firmware for me to flash it with to correct, and perhaps a tool to do it from OS-X??
