So if in the description of the most drivers in ati section is "DSDT Injection" I don't need the dsdt file?Just install AMD accelerator and amd controller kexts?

So I downloaded the AMDsupport.kext and enabled 1080p mode and I have now 7Mb of graphics memory.

Fixed.The problem is my second VGA monitor.I have to unplug it because my primary screen shows only white screen and the second one black screen.

 

Is there a boot flag or something to boot only with my primary HDMI monitor or I have to unplug my second VGA monitor every time I want to boot Mac OS?

 

Or Is there a way to activate the second monitor?

 

Thanks.
