Dell Precision M6600 with Ati Firepro M8900
Mavericks 10.9.4
I've been testing since 10.9 on and off.
Using vanilla install of mavericks 10.9.4 (no multi beast / boot loader no dsdt etc just unibeast usb for booting )
BOOT FLAGS.... GraphicsEnabler=Yes AtiConfig=Osmunda ( with custom edits for lvds )
I have Ati FirePro M8900M fully recognised in system profiler with
correct naming , correct vram 2gb , correct screen resolution for internal screen and 32-bit colour.
Laptop connected to external monitor via dell dock to dell hdmi monitor - 100% screen res .Both screens working together.
Both external monitor and internal screen are correctly listed in system profiler .
External hdmi screen is perfect.Also tested via sony hdmi tv also perfect.
Only issue I have is laptop screen colour is just slightly washed out - still very readable but not 100% perfect
Also vertical size is correct for laptop screen but horizontally screen seems to be stretched -
Correct from left hand edge but apple dock runs off right hand edge of screen.
Can anyone help with tweaking internal screen to clear up the small issues ?
I've been told this line added to a dsdt may help ....
"@0,display-link-component-bits", Buffer () { 0x06, 0x00, 0x00, 0x00 }
I'm fine with editing custom personalities but not so confident with dsdt's .
Have also come across Switchres x , looks promising but never used it before .
Can anyone suggest a fix I can try ?
