Is this a trend? My ASUS VW266H also has a cold color temperature.
Something I saw noted in several reviews. Easily noticeable when placed
along side my laptop's display and a window spans across both displays.

At first I found it objectionable, and tried adjusting the monitor's
built-in settings, which I was never able to get to match the laptop's
display. Now I've gotten used to it, and by comparison the laptop now
appears unnaturally yellow (warm).

I just recently noticed that (in Ubuntu):
System -> Administration -> NVIDIA X Server Settings
Then X Screen 0 -> X Server Color Correction

Not helpful in my case, as it applies to the entire X display, and not a
specific monitor.
