I'm not familiar with Basiccolor. What's software LUT mode? Do Match 3 and Basiccolor have DDC control over the monitor?
If "LUT mode" means adjusting videocard LUTs, are the resulting curves (which I assume are correction curves like in Match 3) close to 1 (run straight down the center)?
More on basICColor display 4 here:
Match 3.6 has closed the gap considerably but I think display 4 still has an edge.
In "Software LUT mode" it creates a LUT for the video card. You can of course just profile it as is (namely with a linear LUT).
The monitor supports hardware calibration but there's currently no software to support it ... AFAIK. An updated version of NEC's SpectraView is on the way. I don't think there's much (if anything) that hardware mode supports that you can't do with the buttons on the monitor, but you do miss out on closed-loop calibration. From what I can currently see, I don't think I'll bother with SpectraView.
Here's the video LUT generated for D50/L*:
The green and blue curves are similar. Most of this is because a gamma of 2.4 isn't exactly L*. If all I wanted was a gamma of 2.2 (or whatever) I'd just dial it (and the colour temperature) in on the monitor and profile it as is. The monitor supports a gamma from 0.5 to 4.0 (in 0.1 increments) and a colour temperature of 3000-9600K internally, though obviously you don't want to move too far away from the backlight temperature. This flexibility is what you're paying for.
