Hi. I have the same problem - not with the Leopard but with the Snow Leopard.

 

I can't find any solution for that. I tried to change the DVI port but it doesn't work eater.

I use custom EFI string for both L and SL. In Leopard - Calibrator Assistant works perfect but it doesn't work in Snow Leo.

 

Is there anybody else with the same problem?

Me to - everything was fine with Leo - but with Snow Leo I can't calibrate my monitor (Nvidia Quadro FX4600 + LG204WT) anymore.

 

The Gamma-Slider of the monitor calibration assistent (System-Preferences) simply shows no effect.

 

Most of the colors appear to bright and look washed-out.

 

Any ideas how to fix this?

 

Thank you and best regards,

Doc
