Systems specs:
Intel Core 2 Quad Q6600
Asus P5G41C-M LX
8GB (2x4GB) DDR3 1600
8800GTS 640
1TB WD HDD
Auria EQ276W 2560x1440 LED IPS 27" Display
This system worked fine in OS X Lion but was using a 9500GT. UniBeast would start the ML installer with a black screen. I used the following to get past the blank screen for the installer:
-V
PCIRootUID=0
npci=0x3000
GraphicsEnabler=Yes
The installer then was able to launch and go to completion. I was able to reboot and use multiBeast. However the Blank screen returned after multiBeast install.
I tried a number of different things including a reinstall as well as removing the 9500GT and swapping it for the currently installed 8800GTS 640. I eventually realized that it wasn't just a blank screen like before though. This time the screen was presumably receiving a signal and wasn't in suspend mode.
So I tried turning off the monitor but it wouldn't turn off via the power button. Therefore I unplugged the monitors power and reconnected it. After that I was getting full 2560x1440 and everything was working (NIC, audio, Bluetooth and so on).
Every time it boots it the same thing though. I tried starting the system with the monitor off thinking it was the monitor not being able to switch resolutions or something but in that case the monitor wouldn't turn on. I had to again unplug the power source before it would work.
Now I'm thinking that maybe if I could force the resolution to something lower it would be fine at boot but I'm not sure if the new scaled option in OS X 10.8 Mountain Lion truly lowers the resolution or does some funky pixel scaling thing. Maybe using HDMI would force a lower resolution or I could try the monitor on a different system but as I said before it was working fine in Lion.
Not sure how I'm going to fix this.
