i am new to the forum but have been lurking for a while... i have a nvidia geforce 8500 gt (512mb) graphics card that i cannot seem to get working fully with mountain lion. ideally i would like to run two monitors, one from the vga port and one from the dvi port using a dvi-hdmi adapter. if i run a dvi cable directly to the monitor it works flawlessly (full resolution with qe/ci enabled) but i get nothing if i use the dvi-hdmi adapter and nothing from the vga port.
note: it does work from the vga port and dvi-hdmi adapter when booting, but the screen goes black and i get 'no input' as soon as osx starts.
graphicsenabler is set to yes
no other graphics kexts have been installed
it was a clean install of mountain lion
my dsdt is attached
system specs are as follows:
processor: intel q6600 core2 quad 2.4ghz
memory: 4gb ddr2 sdram
graphics card: nvidia geforce 8500 gt (512mb)
80gb ide hdd (osx 10.8)
any help would be greatly appreciated :-)
