Hey morpho - if you are still around checking on this thread - were you able to change the offset/gain settings in the service menu? It just seems to jump over those for me.
I just calibrated mine, using a Spyder2PRo colorimeter, and the settings that worked for me were pretty close to the monitors sRGB default settings
brightness/backlight = 50
contrast = fixed for DVI
This gave me a gamma of 2.23, a colour temp pretty darn close to 6500k across the board (6400-6600), and Delta E's of around 1... can't ask for too much better than that... except I notice that the green is a little outside the sRGB colour space (x=.268, y=.603) - but the blue and red are almost bang on. Firmware is version 2.0 on mine
It does look like they tweak these a bit coming out of the factory, as my factory settings are different than morpho's, so settings might not be transferable from person to person.

As a video monitor, you'll want to maximize contrast ratio where you sit further back from the screen.

-These settings only apply to the above brightness settings. A small change in the brightness value alters the gamma and the grayscale tracking.
-ATI gamma only allows for 1/2 increment adjustments . A 0.5 difference in gamma value alters the grayscale tracking considerably.
-Gain/bias are all factory default settings. Be careful when making changes to any of the factory settings as you can lock your display device.
-If doing your own adjustments, start with black level, grayscale and gamma last.
If you don't have calibration tools or charts, here's a few links with sample charts that can help with the black level, grayscale and gamma adjustmentscompare_gamma
