Hi guys and gals,
I was wondering what the problem was with my setup.
I have an Asus P7P55D with an Asus 9800GT that has two DVI ports.
Everything has worked on my 10.8.2 flawlessly via a DVI-DVI cable to a 23 inch monitor. (1680x1050)
I recently upgraded my monitor to a 27 inch (1920x1080), and it only accepts HDMI, not DVI.
So when I booted 10.8.2 with the included DVI to HDMI cable, everything goes fine until I get a blank screen and the monitor goes to stand by because it doesn't get a signal.
I can confirm that it has successfully booted because the caps lock key lights up when I turn caps lock on.
I switched back to my 23 inch monitor temporarily with a DVI-DVI and everything works well again.
When I attempted to reinstall ML using U**Beast, the same thing happened with the new 27 inch monitor (no signal) but it loaded just fine with the old one.
Any help would be appreciated, thanks a lot!
PS. I'm using the first PCI-E slot for the GPU and the main DVI port out of the two. I'm using a DSDT.aml extracted via AIDA64.
I tried to boot from 10.8.3 and 10.8.5 prepared using #####, but they both didn't fix this issue.
