NEC PA271W - When Accuracy and Consistency Matter
by Chris Heinonen on May 1, 2012 1:55 PM ESTNEC PA271W - Input Lag and Power Use
The last 27” display I tested, the HP ZR2740w, was a pleasant surprise for gaming as it had a very low lag time despite the IPS panel and high resolution, likely due to the lack of an internal scaler or LUT to add a delay. Since the NEC has a scaler, and the additional custom electronics to provide display uniformity, I wasn’t certain that the NEC would perform as well.
As you can see, the NEC is not going to be a display for a serious gamer, though it really isn’t targeting that market either. The input lag was 20.5 ms, and the pixel response took 24.9 ms to go from blue to yellow to blue, giving us an overall response time of 32.95 ms. The effective (subjective) lag was a little better, but with that high input lag it was still close to 25 ms, which is more than most serious gamers would be interested in. If you want a 27”, 2560x1440 resolution display for gaming the HP is still your best option.
The PA271W has a built in power use monitor showing you how much power you are using with the display, so being efficient is something that it does aim to do. With the backlight set at minimum we used 51 watts, and at maximum we used 119 watts. These were both worse than the HP as well, but since the HP uses an LED lighting system we would expect it to come in behind. Since the LED lighting system provided for a smaller gamut than the NEC's CCFL system produced, and a less uniform screen, I’m certain that had something to do with NEC's decision to stay with the CCFL technology on this panel. Power use wasn’t bad, it just wasn’t exceptional, and any 27” display is going to use far more power than a 24” or smaller one.

And that's why in the conclusion I have a section that reads "If you are a design professional who needs accurate color more than anything else, and things like display uniformity and a wider gamut are of high importance, then you are the target for the NEC. You already know you might need this, which features you can’t live without, and are willing to pay the extra price."I'm not discounting it because of my use or because I'm not a hard core gamer, I'm drawing the conclusion that if you aren't in that target audience that I already covered in the conclusion, there are other monitors that likely offer a better price/performance ratio for you, or in the case of gaming that offer better performance overall. I tried to cover in depth all of the extra features that design industry professionals would use, as that is the target for the monitor, but also cover it for a general audience as well.

Chris,In this review you state Nec as being top of the line for graphics proffessionals. Ofcourse your review fully supports this statement, and i have no doubt the nec does a wonderful job. However i miss comparisons to the EIZO monitors, as ive been thought EIZO is top of the line for graphical use, albeit a wee bit more expensive. Could you review one of eizo's monitors for comparison? Id very much appreciate it.
kind regards,

How I wish some manufacturer would come along with a 120Hz 2560x1440 monitor already. It's not that not having 3D is such a dealbreaker, but it is awesome and the 120Hz is actually useful in 2D FPSs too. It noticeably improved my performance when I got my Acer GD245HQ 18 months ago.So going back to 60Hz really wouldn't be much of an upgrade, even if I got more pixels.
Oh, and I know 120 is going to be expensive. But I'm more than willing to sell my mother for one.

I have an PA241W, which closely resembles the PA271W. My main problem with it is the mediocre black-levels. The black-levels are fine if its standing in an well lit office though. At home the room often isn't so well lit and then it is fairly obvious that the blacks are worse then of the older IPS NEC screens like the 2090UXi which I use as a second monitor. This difference is because the newer models do not use the A-TW polarizer film. According to NEC the polarizer film was dropped as it increased the color-shift that occurs when looking at the display from the side.What I love about he unit is the great color gamut which can make pictures more alive, and when working with sRGB I only have to press one button on the monitor to switch between color-modes.
The portrait mode is great option which I do use regularly.
Next to that I do use it to game and while I do not play the fastest FPS games, anything non-FPS is not a problem and I even play Battlefield 3 without any problems, maybe the 24" model has a slightly lower input lag then the 27" though the 24" does also have an input lag that is higher then most other displays, so the difference can't be big.

The first paragraphs, which show up in the front page, may be a nice general introduction, but say absolutely nothing about the product - not good for the front page.svojoe - Wednesday, May 2, 2012 - link
I'm curious why they used CFL's? I personally feel that the decent LED back light put out a more even and brighter color than the CFL's. At half the power consumption. 110Watts is more draw than my whole computer!I would have otherwise been very interested in this!

The best CFLs still have wider gamut and lower deltaE than the best LED backlights. Although other people buy them, the 2560 monitor market in general and NEC (among others) in particular are targetting profesional graphics/image/video editing customers for whom color quality is a much larger priority than saving $20/year on their power bill.kmmatney - Wednesday, May 2, 2012 - link
Overall, it seems like the Apple 27" is better - and cheaper even factoring in the $30 DVI adapter, while coming close to it in color quality.cheinonen - Thursday, May 3, 2012 - link
With any of the 27" panels tested so far you could say they are "close" to the NEC, but for some people they need that extra bit of quality and uniformity for their work, irregardless of cost. It costs a lot more to get it since it takes a lot more work and engineering, but for some people it's a necessity.nurfe - Thursday, May 3, 2012 - link
Except that Apple won't support 14 bit lookup-tables, hardware calibration, and it won't electronically correct uniformity and colour variation problems. If nothing I mentioned matters to you, go for something cheap. If you care about it, you'll get a NEC, EIZO or Quato.
