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.

I'm still not able to figure out why people buy the Apple LCDs... displays from other manufacturers in the same price range have far better specs. If you compare performance to price, the Apple options are at the bottom of the list. They really aren't that good. Sure, they're great compared to a $150 Dell, but next to other options in the 27" size they don't hold up very well.ectoplasmosis - Wednesday, May 2, 2012 - link
They use the same panel as all the other 27" 2560x1440 screens (as far as I'm aware, LG is the only manufacturer making such panels).Apart from backlighting and features, the rest of the differentiation is in the panel manufacturing variance.
I bought mine because it's glossy (huge bonus for me), it looks fantastic and comes with serviceable speakers and a webcam built-in. And the after-sales service means if it goes tits up I can drive 5 minutes down the road and get an instant exchange.
All those things are worth the premium in my eyes.

It works fine with Mini-DisplayPort to adapters.Not sure where you got the "only works with Thunderbolt" from though.

I've owned the PA271W for over a year now and it's been very great to me. I work as a web developer/designer and everything looks sharp and accurate. Surprised Anandtech just got around to showcasing the monitor.bishop2020 - Tuesday, May 1, 2012 - link
You guys have reviewed the Dell U2711 in the past and it strikes me as the most comparable monitor to the NEC, curious why it would be omitted from the comparison tables while a bunch of smaller panels were included.InterClaw - Wednesday, May 2, 2012 - link
That, and the Dell U3011 as well is strangely missing now.cheinonen - Wednesday, May 2, 2012 - link
Once I get past 15 results in the data, it becomes too hard to read the results. I've been favoring the more recent results since they are done using the i1Pro and not the i1Display2, and so the results are more accurate and more directly comparable. I will see if I can pull in the 27" and 30" numbers for the past displays to replace those that are in there this week.bishop2020 - Wednesday, May 2, 2012 - link
Thanks, looking forward to seeing the numbers side-by-side. In my opinion anytime I see reviews for 2560 res monitors I see them as an entirely different class of monitor and the price especially seems to segregate it from everything else as well. I could see throwing in 1 or 2 of the higher-rated 1920 screens for reference but anyone whose even considering spending $700-$1200 for a monitor probably knows they want a 2560 res monitor for a reason and isn't considering a 1920 at all so the other numbers just add noise to the data they're really looking for. Thanks again :)Veni - Tuesday, May 1, 2012 - link
The NEC's built in KVM/USB switch functionality is very intriguing to me. Does anyone know of any cheaper monitors which have the ability to switch the USB uplink based on the display input?tygrus - Tuesday, May 1, 2012 - link
".. for my use .."Reviews like this should have multiple headings with sections targeted at a different audience. It's OK to include your 'general home use' self but don't forget that there may be others who do graphical/multimedia work or hobby that appreciate some of the more advanced features. Let the reader choose which target audience they are and focus on a different conclusion. Don't discount just because it's not recommended for gamers.
