Hello,
I have a little problem with my OS X Mavericks installation: every time I boot , it randomly assigns video signal to one graphics card , each time being absolutely random. If I unplug the DVI cable and plug it in each , one of them always has signal and works like a charm.
The problem is that Windows 8.1 as well as bios post use the first card for video output and I'm trying to force OS X to output through the same GPU always. I don't really want to move the cable each time I boot in OS X until I find the GPU that outputs at that time.
I have 4 GPUS with a total of 8 possible DVI slots , running W8.1 and OS X on separate SSDs.
Thanks in advance,
Mike
