HD4550 no QE/CI after graphics update

[freeza]

I've tried virtually everything I can think of to get QE/CI back enabled on my HD4550.

 

I have PC EFI 10.6

SL 10.6.4

 

 

and it worked fine (cept with green apple) but with the graphics update, QE/CI has become disabled.

 

Any ideas?

finally add support CI/QE in HD4550 (SnowLeopard 10.6.4) after playing around with different versions of ATIRadeonX2000 and ATISupport kexts.

 

ATI4500Controller & ATIRadeonX2000 from 10.6.2 ATISupport - from 10.6.4. EVOenabler for HD4890, with modified device properties for HD4550 (ioreg helps).

 

Last thing i can't manage - right resolution. i have resolution change - up to 2600 and more. but my monitor is 1080p (1920x1080), in my list i have 1600x1200 (working) next one is 1920x1440 (not working, monitor says "out of range")

annoying... was trying to flag it with "Graphics Mode" - no changes.

 

any suggestions?

 

P.S i have green apple logo too ))
