NEC EA244UHD 24-Inch Ultra HD Monitor Review

Results: Viewing Angles And Uniformity

To learn about how we measure screen uniformity, please click here.

Even though this is an AH-IPS display, its off-axis image quality is not quite as good as other IPS screens we’ve photographed. But it is a match for Dell's UP2414Q. Obviously, the horizontal red shift is endemic to this LG panel. Inside of 45 degrees, however, there is almost no change in color or luminance. And it’s still superior to the current crop of 28-inch Ultra HD TN-based panels.

Screen Uniformity: Luminance

The uniformity compensation doesn’t do much in the black field test. A 1.15-percent reduction is completely invisible. At least contrast isn’t affected too much. Our C6 shows hotspots in the upper-right and lower-left zones.

Here’s the white field measurement:

The white field result drops by more than half, although 5.77 percent is still a great result. In terms of brightness uniformity, you really don’t need uni-comp.

Screen Uniformity: Color

The biggest improvement comes in the color uniformity test. A result of 3.28 Delta E is just-visible. We could see the barest suggestion of green in the upper-right zone. When we turned the compensation on, it went away. You’d never notice such a slight aberration in actual content.

Our conclusion after testing several monitors with uniformity compensation is that modern LCD panels are improved to the point where the feature is unnecessary. Since it always reduces output and contrast, we leave it off. Only the most sensitive user would find a need for it.

Pixel Response And Input Lag

Please click here to read up on our pixel response and input lag testing procedures.

The screen draw result matches Dell's UP2414Q which is what we'd expect. The EA244UHD also beats the two QHD IPS screens by a small margin. For those seeking the shortest scan times, TN is still the tech to beat.

Here are the lag results:

Input lag this high makes fast-paced gaming difficult. While you can run the monitor at 60Hz, there’s still too much delay to enjoy a first-person shooter. If fast reflexes are not required, the EA244UHD’s pixel density makes for stunning images in more mainstream titles.

    48 inch, i can't imagine using a 4k at any less than 48 inches.

    SST or MST please for 60Hz??

    That's no telly, it's professional desktop monitor, could be 27 or 30'' but would probably cost another 1000 or more extra.

    Agree with alidan, at this density, pixels are wasted: you don't see more as you need to scale everything up.
    And, knowing the hardware you need to drive this resolution,, I don't see any interest except for some niches.
    You need at least 44'' to exploit 4K.

    UHD is 2560x1440/2560x1600 - not 4k. Even if it was 4k, I don't see how you can say it is wasted.

    @myself - I was incorrect - I am a dumb ass.

    QHD = 2560x1440/2560x1600
    UHD = 4k

    UHD = 3840x2160
    4k = 4096x2160

    The problem with these high-DPI screens is that support for these displays is lacking in many modern OS's. Yes, support is getting better, as with Windows 8.1 and its better UI scaling, but even with good support in the OS's UI, you're still at the mercy of the apps you use, and many are terrible when it comes to high DPI, with some even failing to work properly.

    Retina is only useful when your programs provide good support for it. Otherwise it's just an annoyance. As an owner of a Yoga 2 Pro (13" 3200x1800), I can speak to this. I normally run my laptop in an upscaled 1920x1080 just to keep compatability.
  • atwspoon
    So what about tablets and phones using UHD or 4k in the future?
    The Pixel Chromebook looks quite pretty with its 12" screen and 2560x1700 resolution. That's a small laptop, but moving in the right direction I think!
  • eklipz330
    yeah, i cant imagine widespread pc 4k adoption until we have video cards that can run it. i mean, we're still struggling with 2560x1440 resolution. there needs to be a massive improvement in gpu power in the next year
  • vincent67
    Of course, I also found these extra pixels, above 1920*1080, for tiny screens from phones or tablets superfluous and no less wasted! Everything is scaled up so you don't see more stuff!
    This is similar to digital cameras where the resolution becomes useless passed a certain point.

    While true of a TV at normal viewing distance. This is complete and utter BS for a desktop monitor. My eyesight is not that great and i can easily see the pixels(if i look for them) on the 1920x1080 monitor im staring at as i type this.

    The move to 3840 cant happen soon enough. If i had a spare 1,400 id be all over this monitor. But i dont, i have to wait till the price comes down. Also wait for the refresh rate to go up, 60 is too low.

    185ppi will be hard to see unless you really try hard. But sub 100 its pretty easy to see the pixels. The desktop world has been stuck with 90-110ppi for FAR FAR too long.
  • none12345
    As for scaling, apps designed for 1980 scale perfectly to 3840, you just double everything. The the image will look identical to what you have now.

    Granted there are some issues, like the windows app notification message that tells apps when they are being scaled. And some apps ignoring this message and telling windows back that it can handle the resoultion properly when it cant. Thats an issue. But for every app that doesnt cheat like that, and just renders itself, you can scale it easily.

    Its the wierd ppi monitors that have problems scaling. You cant scale an image designed for 90ppi to 150 without screwing up the image. You can scale 90 to 180 easily and it will look perfect.

    As far as games go. Just turn down the AA setting, and you achieve the same framerate with a better image on 4k then you do on 2k. With AA on youa re already rendering at the higher pixel density, then downscaling it to be displayed. Downscaling takes processing power, turn off the AA and its the same thing only faster. AA becomes unnecessary once you increase pixel density.

    I am interested in further explanation of the Vincent67's assertion that digital camera resolution becomes useless.

    Like none12345 mentioned above, it is totally dependent upon the intended usage of the product.

    4K computer monitors are being viewed at extremely short distances.
    If a photographer wants to produce very large prints from a digital image, resolution becomes paramount.

    So, while there is certainly a point where the cost of increasing resolution capability becomes inverse to the need of a "typical" use, that point will not be the same for someone utilizing those higher resolutions for atypical applications.

    IMO, smaller 4K displays still provide a ton of utility. Whether or not that utility is something a typical user would benefit from is largely irrelevant when one considers that a typical user is not going to be in the market for a $1300 computer monitor.
