XFX 6850 and Powercolor 4650 in Lion

[Alex Hoover]

Hi,

 

First post here, long time lurker. I've installed OS X Lion using Chameleon via a USB stick. I have 4 monitors and 2 video cards. I have 3 display devices connected to the 6850 (monitor via dp, monitor via dvi and TV via hdmi) and 1 connected to the 4650 (monitor via dvi). Originally, I had only the first card enabled and GraphicsEnabler set to NO which allowed the three devices on the 6850 to work, but not on the 4650. I installed 4650 kexts and now the device on the 4650 works.

 

The issue is that the HDMI and Displayport devices act as one, and the 6850 shows up as "monitor" in system profiler. Essentially, both screens are mirrored in a fixed resolution (1024x768). My system specs are as follows:

 

• Asus P5Q Pro
  
• Core 2 Quad Q6600 @ stock
  
• 4GB G.SKILL DDR2
  
• XFX 6850 1GB
  
• Powercolor 4650 512MB
  

 

 

Thanks in advance,

Alex
