I'm shopping around for wide color gamut monitors and have narrowed my choice to the 4-year old NEC PA271W and the new NEC PA272W.
My main concern is the image quality of the screen. Although the older model lacks HDMI and a mini Display Port, I'm okay with that. I use modern Macs and there are Display Port to mini Display port adapters.
The older model is an LCD, while the newer model is LED. I love looking at the color on my Apple LED screens; they are much better than their older LCD screens.
B&H has a new NEC PA271 for $800, I already have a Xrite ColorMunki calibrator, and I can buy the essential Spectraview II software for $90 (which is compatible with the ColorMunki). I do understand that the NEC-branded colorimeter is an Xrite specific for that screen, but the SV software, which directly controls the screen, still works with the ColorMunki.
B&H also has used NEC PA271Ws for just under $600. Potentially I could have a great, color calibrated screen for under $700 (used) or under $900 (new).
The new NEC PA272W has more modern connections, which are nice but not essential. I am most interested in the LED screen. If the color is sill accurate but has a better contrast ratio and deeper blacks, then I'm all for it! The new one is $1450 at B&H with the software and calibrator package, or $1253 without.
I think it is about 30% thinner than the older model as well, and uses less power. Nice, but not essential.
I have read Lloyd Chamber's reviews of both. His comments on the screen differences are not very specific. Unfortunately there are no stores in my area that carry either monitor.
He says of the 30-inch PA302W (model with equivalent features and image quality): "I’ve been using it for the past 4-5 days and I like the PA302W a lot already; the screen is both sharper and smoother and the color gamut is even wider than the NEC PA301W which I have used for several years."
