Meet the NEC EA244UHD

The NEC EA244UHD is the first UltraHD (UHD) monitor from NEC. While it's not from their professional line, it has many of the features we've come to expect in their monitors: uniformity compensation, a wider color gamut but also sRGB and AdobeRGB support, and many user configurable settings. It also has a few things NEC has never done before including SpectraView calibration support on an EA-series model and full USB 3.0.

The EA244UHD is also loaded when it comes to connectivity. There are dual DisplayPort 1.2 inputs, HDMI, HDMI with MHL, and dual DVI (but these are only single link). I wish there was a Mini DisplayPort input like Dell has on their UHD displays, but there are still enough inputs here for anyone. With so many inputs, the NEC can display a single input at once, two side-by-side (with auto-expansion), three at once, or even four where each gets a FullHD 1920x1080 area. The Auto-Expansion mode allows you to customize the width of one half of the display and the other half automatically adjusts. There is also a USB 3.0 hub with three USB 3.0 ports, and as a sign that someone is listening to comments, the headphone jack is on the side of the display instead of the bottom or rear, where it is easy to access. Hooray for small victories!

One difference with the NEC EA244UHD compared to other UHD monitors so far is that it defaults to MST being enabled for DisplayPort 1.2. With other UHD monitors I have had issues where MST would stop working, or the monitor would not come out of sleep. The NEC is designed to drop out of MST mode if a display card doesn’t support it, but I can’t test this since all my video cards do support MST. I’m not certain if MST always working correctly on the NEC is because it is enabled by default, or because video drivers have been updated since the last display to fix the problem. Whatever the reason, the NEC EA244UHD works at 60Hz without a problem.

The backlight of the EA244UHD is a G-B LED one as we have seen on other displays. This allows for a larger color gamut than traditional white LEDs but the lower power use and heat output of LEDs compared to CCFL backlights. Built into the EA244UHD are preset modes for the sRGB gamut, AdobeRGB gamut, DICOM (medical imaging), and the Native Gamut. There is also a Programmable mode, which relies on the SpectraView II software to calibrate the display.

Also in the menu system are a few more custom NEC features. The Human Sensor detects when you are at your desk and keeps the monitor on. If you’re away for a defined period of time, it will turn off. Yes, you can use the power options to do this, but there might be reasons you don’t want to do that and you can accomplish it here. The Uniformity option increases panel uniformity at the expense of maximum brightness. I always test with this on as the maximum brightness is still bright enough for almost anyone and the uniformity really does improve.

If you want to hook up more than one NEC monitor, you can chain up to six of them together. Doing so will let you adjust the brightness, mode, and other settings from a single unit. (This is just in case you need six UltraHD displays, because that sounds nice.) NEC also ships the EA244UHD fully assembled, including a stand with height, tilt, and pivot adjustments. NEC is using a new air-packing method for this display, which is a nice change from the styrofoam most people use. It weighs less, is easy to reuse and recycle, and makes no mess. Those that test 15-18 monitors a year like myself really like to see this, and I hope more vendors follow this method of packaging.

    Win 8.1 does support different DPIs for different monitors. AIUI Metro/WPF apps have the ability to handle it built into their UI library; apps using anything else can either set a flag saying they support per monitor DPI or are locked to render in the DPI of the first monitor they open on and are scaled when moved to one with a different DPI.

    That sure is an ugly stand for such an expensive monitor.
  • Sabresiberian - Thursday, August 7, 2014 - link

    The DPI isn't too high; the applications are simply behind the times. Software engineers should have had this figured out by now and acted so that UHD @ 24" wasn't a problem. And, scaling is only going of become more of an issue if they don't in the next few years.
  • althaz - Friday, August 8, 2014 - link

    Agreed. Developers (of which I am one), have the tools at their disposal to make applications scale well. For the most part however, they don't and I'm really not sure why.

    From what I can see, it has to do with the custom UI frameworks. If you stick with the MS's UI widgets as much as you can, you shouldn't have a problem scaling it. However, if you're using a custom coded one, you're going to have a bad time.

    In Delphi for an example, some components would render just fine by setting a manifest on it but some components require you to give it custom scaling calculations to make it work. So, you can see different reactions from different components that were coded differently at different eras. For them, they just don't have the time and/or resources to figure it out as the market for folks with HiDPI screens are still a niche.

    Plenty of Windows components still doesn't scale at all except bitmap. If the OS it self can't do it well why should anybody follow?
  • Pinkynator - Friday, August 8, 2014 - link

    This is the first time I've ever seen calibrations to 80 and 200 cd/m2. Usually it's 120...
  • Clorex - Friday, August 8, 2014 - link

    We already have monitors that do 4k single-stream over DP 1.2; so why are there still MST monitors being released?
  • SanX - Friday, August 8, 2014 - link

    I really do not understand people who want 24" 4K monitors and not 30-40". They have different DNA. I do not understand producers either.
  • MrSpadge - Monday, August 11, 2014 - link

    That's probably why are not one of the display producers, then. Not everyone has the desk space to put 30 - 40" monitors far enough away so that the viewing experience is pleasant.
