Why you can trust Tom's Hardware
Viewing Angles, Uniformity, Response & Lag
To learn how we measure screen uniformity, please click here.
The EA275WMi has some of the best off-axis image quality we’ve seen outside of an AHVA panel. The side view shows only a slight output reduction and a miniscule color shift to blue. From the top, gamma hold up well, though the red tint and light falloff are a bit more obvious. From normal viewing angles and distances, this is one of the best monitors we’ve seen to date.
We expect a premium-priced monitor like the EA275WMi to have excellent screen uniformity right out of the box. NEC still includes a compensation feature and it does improve our test results, but the contrast and output reduction that comes in the bargain may be an issue for some users. You can see by our measurements that black level is largely unaffected. You won’t see a difference between 6.44 and 5.41%. Our sample shows no bleed or glow whatsoever.
In the white field test we recorded similar results except that the compensation reduced aberrations to a tiny 2.03%. If you need absolute perfection, the feature certainly works as advertised.
In the color test, we saw almost no difference between the two settings. Our meter actually measured a slightly higher range of DeltaE values but neither result is close to the visibility threshold. The EA275WMi sample we received demonstrates superb performance and quality control. We have no data for the PB278Q because its review pre-dates our color uniformity testing.
Pixel Response & Input Lag
Please click here to read up on our pixel response and input lag testing procedures.
With the ControlSync feature, we thought the EA275WMi might be a great choice for gaming with a multi-display setup. Unfortunately, there is a little too much input lag for those with quick reflexes. Casual gamers will be satisfied with this display but first-person shooter titles with fast action will be a little less satisfying. Screen draw is as expected for a 60Hz IPS panel, so motion blur isn’t really a problem in any case. Of course, a 27" QHD monitor at this particular price point isn’t likely to be on many player’s short lists.

That's a sweet little monitor you got there. I run four 23 in Lenovo LCD monitors here on my trading station. Looking to do a server upgrade next spring and go with 32 or 36 in monitors. Getting old. Sometimes, the pips are hard to see...lo!Reply
NEC monitors are always a beauty. Nice matte black, not the shiny piano black we see everywhere. These always go toe to toe against the Dells that cost more.Reply
"NEC’s much vaunted build quality"Reply
Both of my EA231wmi monitors died just after the 3 year warranty expired.
Love my NEC PA27W - its still going strong after several years of use. NOT cheap, but it should last through several system upgrades.Reply
and despite what the gaming sites say, its great for games and movies, general use..and the occasional photo
what is uc on uc off in the contrast page?Reply
I'm so fed up with these 27" monitors. Why can't they make something a little larger. 32-40. My 30" 2560x1600 monitor is almost a decade old but I'm yet to see anything that tempts me to upgrade. I'm probably going to have to hold out until 8k becomes mainstream and we get 8k 40" panels.Reply

It may not be the best monitor, but its a 40 inch 4k monitor.
Honestly Im toying with the idea of a 2 monitor setup myself, something massive for every day use, 40-50 inch 4k, especially if i can get 10 bit and a fantastic contrast ratio, and then something for more demanding things like gaming
also, 8k is never going to be a thing, at least till its so trivial to make the panels it just out right replaces 4k for the same price. 4k looks amazing in a store, when you are up close, you see the crispness, but then put the 50-60 inch tv 7-10 feet away from you and that 1080p tv right next to it looks the same for far less money., the same will be true for 8k, on a computer, there is a practical benefit for photographers, artists, people who work with video, but for the normal person they ui scale their crap up the monitor looks the same as the old one maybe a bit crisper in areas, but it takes 4 times the hardware to run it even idle.
the next thing that will push monitors forward is oled, possibly quantum dot if they emit their own light, don't know enough to make a call there. Not sure if you know this, but contrast is the number 1 thing that determines how good a monitor looks ot normal people, nothing else matters so long as its at least tn quality, but contrast is king. its funny to me how much manufactures lie on boxes for this too, had an argument with someone who claimed his 3000:1 monitor was worse then his apple 5k, and i had to dig up a review for his monitor where they did the contrast test and not just put out a press release, turns out that his monitor was actually about 800:1 and apple is around 1250:1
contrast ratio is what will push sales of tvs and monitors next, and it will be oled or qd that do it. and you want the normal people to adopt things enmass, just because that drives the price down faster.
Yeah, I know about the 40" 4K one. I've thought about it numberous times but it doesn't really feel like enough of an upgrade - it's about the same DPI as my 30". I'd like a bigger size with more pixels and a higher resolution too. 5k at 40 would be perfect. I'm using two 20" 1600x1200 monitors in portrait mode either side of my 30" and I'd ideally like a larger monitor that I feel can replace the whole lot. If they'd made 32" 5k monitors instead of 27", I would have bought one years ago.Reply
