... The Eizos have an internal ambient light sensor, and automatically calibrate to a sensible luminance value for ambient light. ...

The NECs have something similar. I have assumed that one would not want to use it, as there is no real control over the luminance value of the display that way, but I will admit I haven't tried it. Andrew, have you tried it on your 2690? What's your view on use of this feature?
EDIT: Well that's interesting... I just checked and see that I have "Use Auto Luminance (if supported)" checked on. I recently reinstalled my whole system from scratch and had overlooked that setting. What exactly, if anything, is it doing? (It doesn't appear to be doing anything at all.)
FURTHER EDIT: Ah, the answer is in the 1.0.42 ReadMe: "Added Preferences option for using Auto Luminance feature (available on the NEC LCD2490WUXi, LCD2690WUXi, and LCD3090WQXi)." That doesn't include my 2090uxi. Wonder why not? I think it has the hardware capability, at least in some measure.
YET ANOTHER EDIT: And the answer to that question is found in the User's Guide: "Use Auto Luminance (if available) - enables the Auto Luminance sensor inside the the display monitor to increase the Intensity (brightness) stability as the display ages and warms up. This feature will not be used for Targets with 'Maximum Possible' Intensity selected, or if the Target Intensity falls outside the range that the Auto Luminance circuit is capable of controlling. This feature is only available on the following models: LCD2490WUXi, LCD2690WUXi and LCD3090WQXi." So this feature has nothing whatsoever to do with adjusting for ambient light levels. Never mind.
