NEC EA244UHD 24-Inch Ultra HD Monitor Review

OSD Setup And Calibration Of The NEC EA244UHD

All of the EA-series monitors we’ve tested employ the same OSD. It’s pretty extensive and covers not only calibration, but many other features like PBP, energy use and ergonomics. To bring up the main menu, touch the Menu button.

OSD Tour

Every option has a little fly-out box, similar to the one above. Navigation is intuitive, and we're confident that you'll quickly adapt to it. Brightness controls the backlight, as expected. But you do get a separate Black Level control. For PC signals, we left this setting at its default. From the factory, Eco Mode is turned on, which limits brightness. Turn it off to unlock the monitor’s full luminance range.

The Human Sensing options utilize sensors on the EA244UHD’s bezel. They can detect the presence or absence of a user and turn off the monitor when appropriate.

The final field contains the six picture modes. You really only need to use Standard since the actual color modes are contained in another menu.

Image size and position are adjustable if your incoming signal is lower than native resolution. Moreover, Video Level can be set to Normal or Expand, though the option only works with the HDMI inputs. Normal is fine for PC signals and Expand is used for video sources like Blu-ray or cable boxes.

Response Improve increases the pixel clock to minimize motion blur.

Uniformity is a compensation feature that can be either on or off. It’s only designed to affect white, not the entire luminance range. In our tests, it reduced brightness by 15 percent, and had a positive effect on our white field and color uniformity tests.

There are five color presets: Full, sRGB, Adobe, DICOM and Programmable. You're able to manipulate each one through the RGB sliders or the full CMS. Programmable is used when you calibrate with the SpectraView application.

The CMS has Hue, Offset (luminance) and Saturation sliders for each color. Our out-of-box measurements were so good that we couldn’t make any improvement with them. It’s great to see such a complete set of image controls in a business-class product.

Flip over to the next menu and you get audio controls that include volume and source selectors. Video Detect automatically switches to an active input when a signal is present.

The star feature is Multi Picture, though. You can have up to six sources active at once with as many as four displayed on-screen simultaneously. Choosing one in the Active Picture sub-menu lets you adjust image parameters for only that source. It’s pretty cool and eliminates the need for a separate matrix box in multi-source applications. We can see this being particularly useful in video surveillance systems.

The remaining options address energy use. You can dim the power LED, set a power save timer, shut off power to the USB ports and return all settings to their factory defaults.

The OSD is available in nine languages, can stay on-screen for up to 120 seconds or be locked out completely. Hot Key refers to the bezel keys for volume, brightness, input and multi-picture. You can turn them off if you wish. Data Copy and Customize Setting work with the ControlSync feature. With that, you can daisy-chain up to six EA244UHDs and control them as a single unit.

NEC always includes energy usage info in its products. You can enter your per-unit costs and see exactly how the monitor impacts your monthly electric bill.

Finally, you get a basic signal information screen with resolution, refresh rate and the monitor’s serial number.

Calibration

The EA244UHD is the first monitor we’ve ever reviewed that could not be improved by an instrumented calibration. It’s so good out of the box that nothing we tried would make it any more accurate. The only adjustments we made were to set max output with the Brightness control, along with a slight reduction in the Contrast slider to clean up the 100-percent luminance level.

We settled on settings of 59 for Brightness and 48 for Contrast in both sRGB and Adobe RGB modes. The Sharpness control was left at its default of 50.

    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.

    @vincent67
    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
    @atwspoon
    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.
