N6600 and colour saturation

N6600 and colour saturation

[B. Bogart]

Hello all,

I have an older machine with an AGP GeForce N6600 Nvidia card. I 
recently bought a new colour calibrated monitor to replace an old CRT 
and I've since noticed a stark difference in the colour produced by the 
N6600 and my newer machines with series 5 and 7 graphics cards. The 
newer cards show similar B+W contrast, but colour is much less saturated 
on the N6600.

I had been running Nouveau, but switched to the nvidia binary driver to 
see if it made any difference; it does not. I tried changing the 
settings using the nvidia driver on the newer machines (brightness, 
contrast, gamma, colour range), but the lack of saturation on the n6600 
does not visually correspond to changes to "the colour range", gamma, or 
contrast.

Is this lack of colour saturation due to a hardware limitation, or is 
there something that can be tweaked in the Nouveau settings?

I was just hoping there could be some solution to make these machines 
somewhat colour matched.

Thanks,
B. Bogart
