I have DVI working no probs, and my hdmi port mirrors the dvi, and it seems impossible to get the other monitor recognized through hdmi for dual monitors.
I too needed to prioritize silence over functionality this time unfortunately and since I am in Sweden, nothing except a mysterious cable with no specs seems available to me.
I going to pick up the cable in question anyway and try it out, will let you know if it works.
Also, my displays are only running 1920x1080 which means single link dvi would suffice, and if I have understood things correctly might have a higher chance of running.
Anyway, i'm off to pick up the cable...
Edit: Well, that didn't work, there doesn't seem to be any issues with the actual cable, but I get the exact same result as when using HDMI, a mirrored screen of the DVI.
Someone earlier in the topic reported that both displayport and hdmi were reporting use of 0x400 through IoRegistryExplorer, which seems correct. Don't know what my next step is, but I guess I will continue trying to force things. If anyone has any pointers, do be afraid to throw em my direction
Edit 2: Still no success, have also tried the displayport and hdmi combo resulting in two black screens after apple boot screen. Is AnVAL causing this? Do I need to switch to Chameleon to get it runnning? Extracted the rom for the card from windows along with the DSDT, loaded with UseAtiROM yes option but does not seem to make any difference. Do i need to patch the DSDT or the rom if that even is a possibility?
Hate to be a noob, but i'm kind of new to Hackintosh.
