I am in the market for a new screen, one that offers a wide gamut, better brightness uniformity, and a hardware LUT. The NEC PA271W 27" screen is currently the front runner, with a couple from Eizo coming in a close second and third. The newer Eizo screens seem to come with a built-in calibration device, and self-calibrate. They cost an unholy fortune, though, so that convenience will probably not find its way onto my desk.
The NEC PA series also has a hardware LUT, and seems to make use of SpecraView II software to do calibration. I have not been able to find any solid information about which calibration devices work with it...it seems SpectraView supports a variety, but I have been unable to find a list of explicitly supported colorimeters and spectrophotometers. I own a DataColor Spyder3 Elite, which has the ability to program LUTs with its own software. It seems you can't use third-party software with the PA series, only SpectraView. I would love to know whether NEC's PA series or SpectraView II support that specific colorimeter, so I can avoid buying another.
