NEC PA271W - When Accuracy and Consistency Matter
by Chris Heinonen on May 1, 2012 1:55 PM ESTNEC PA271W - Color Quality and Color Gamut
Targeted directly at designers and other graphics professionals, we’d expect to see excellent performance, hopefully before and after calibration from the NEC. For the initial measurements, with so many options available, I used the included ICC profile and set the monitor to sRGB mode as well as 200 nits of light output.
Pre-calibration we get an error of 7.07, which is a bit higher than I thought it would be, with a really high error in the grayscale. Overall this was OK, but I highly doubt many people will buy this display without choosing to calibrate it given its target market. Our target settings were a 2.2 gamma, D65 white point, and 200 nits of light output. ColorEyes Display Pro doesn’t give a color gamut option, so I assume it is targeting the native gamut of the display.
This is much better after a calibration, with an average dE of only 1.51 and a median dE of just under 1.1. You’ll notice the last color sample before pure white, a turquoise blue, has a much lower error here than on most displays. This is the shade of blue that actually lies outside of the sRGB colorspace and so most displays cannot reproduce it, leading to a very high dE there. The only panel to do better recently is the 30” NEC that has a true 10-bit panel.
As the print market is a main area for NEC to target with this display, its performance with 100 nits of light output is of more importance than usual. Here we find that the NEC performs almost identically to its 200 nits results, which is actually quite good. As many displays get better or worse as the light output changes, that indicates they will only perform at their best at a certain light level, whereas if you are consistent the user can set the light to match their environment. The NEC doesn’t run away from the competition in any of these tests, but it performs very well, and very consistently.
You won't be lacking for gamut here either, as the NEC covers over 109% of the AdobeRGB gamut, meaning that for any work you are doing, even including something like DCI Cinema, the NEC has you covered.

I have three bones to pick:1. The sRGB color space is important, more important than AdobeRGB for most users, and yet Anandtech's monitor reviews always fail to provide information about sRGB coverage and use AdobeRGB as the baseline for comparison.
2. The chart heading calling monitor gamut "color quality" is misleading, especially when dealing with wide-gamut monitors that have non-functioning sRGB modes -- leading to overly saturated color when viewing sRGB content. For many users, such a monitor would be considered to have inferior color "quality". Also, for sRGB content, a standard gamut monitor with good uniformity and good black level would have good "color quality" when used with sRGB content—potentially better than a wide-gamut monitor with poor black level. Change it to "color range", "gamut", or something else that doesn't give the impression that the colors the monitor is capable of representing are somehow better simply because there are more of them.
3. There is still no mention of PWM flicker in the article, or whether or not this model uses PWM or constant control.

The other problem with "color quality" as a heading is that it doesn't reflect banding, noise, and other issues related to FRC dithering, the lack of a hardware LUT, broken hardware firmware (as was documented in the Dell U2410 by prad.de -- user mode wasn't working properly), and such.bjnicholls - Wednesday, November 28, 2012 - link
sRGB is a small subset of ARGB. Any wide gamut display used with proper color managed workflow can accurately display the thin, weak color gruel that is sRGB.sRGB is the "least common denominator" color space and the only thing important about it is knowing how to deliver images optimized for sRGB with as few negative effects as possible.

A review of any "professional" grade monitor would not be complete without benching it against the gold standard : Eizo. On reviewing Anandtech archive the last review of an Eizo was in 2006, a shootout involving Eizo L997, which duly came out as the champ. On the strength of that review, I bought one for nearly US$2,000 in 2006, used for viewing CAD drawings. Look forward to a "hottubbing" of the NEC, Eizo and other professional monitors.appliance5000 - Wednesday, January 2, 2013 - link
I think NEC is as much a gold standard as Eizo - has that ever been a question.UrQuan3 - Thursday, May 3, 2012 - link
You know, the funny thing is I *HATE* dimming backlights. It's like a car that adjusts the volume based on how fast you're going. I'm sure it makes benchmarks give better numbers, but it's really unplesant to use.The backlight on my laptop changes based on how much white there is on the screen. The effect is that everytime I open a menu, all the colors on the screen change. It's implemented in the Sandybridge drivers and cannot be turned off. The only way to prevent it is to run the screen at full brightness. That seems to disable the dimming.

FWIW, I hate it when cars DON'T have auto volume based on the speed you're going. What sounds appropriate at 70 on the highway is absolutely blasting when you come to a stop. Don't understand what you'd have against it.bobbozzo - Monday, May 7, 2012 - link
Yeah, the 'dynamic contrast' on my Samsung 2343BWX is unbearable for PC work. Fortunately it is easy to turn off.mtfreitasf - Thursday, May 3, 2012 - link
I have been following your monitor reviews for a while but have never heard about Eizo which has a name in the pro market. Is there an explanation for this omission? Yours.
