NEC EA244UHD Review
by Chris Heinonen on August 7, 2014 2:30 PM ESTMeet 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.

I think a better solution than the chroma subsampling to achieve 4k60 today would be to use two connectors and stitch the picture together at a high level. It would take bigger buffers on the display and some additional circuitry but there's no reason a display driver couldn't pull this off with existing hardware. 4k60 is already the high end so I don't see why corners need to be cut, especially when displays like this tick all of the feature boxes and come with a bajillion different connectors.NECDisplaySolutions - Friday, August 8, 2014 - link
Hello. This can be done on the EA244UHD with the Picture by Picture modes, either 2, 3 or 4 way. A 4-way Full HD configuration over HDMI and DVI would give you 60 Hz support. Or you could just use 1 DisplayPort cable.marcosears - Thursday, October 9, 2014 - link
This is a nice try from NEC, but it just doesn't meet the standards of some of the really good monitors on the market today. /Marco from http://www.consumertop.com/best-monitor-guide/fpsdean - Friday, October 9, 2015 - link
LOL! TN panels are garbage! Watch what garbage you post -- none of those monitors are even good.gevorg - Thursday, August 7, 2014 - link
Does it use PWM? If yes, at what brightness levels?http://www.tftcentral.co.uk/articles/content/pulse...

This is an LED-backlit model, so it almost certainly uses PWM for backlight control. I'd be interested to know what frequency it runs at.xenol - Friday, August 8, 2014 - link
Not every LED backlight uses PWM.NECDisplaySolutions - Friday, August 8, 2014 - link
Hello. The PWM frequency on this monitor is 23kHz. You can see all of the product specifications for the EA244UHD here: http://www.necdisplay.com/p/desktop-monitors/ea244...Ahriman4891 - Thursday, August 7, 2014 - link
PWM frequency is 23kHz, mentioned in this press release: http://cinescopophilia.com/nec-4k-24-inch-multisyn... and confirmed by a NEC rep on hardforum.NECDisplaySolutions - Friday, August 8, 2014 - link
You are correct. The PWM frequency on this monitor is 23kHz. You can see all of the product specifications for the NEC EA244UHD monitor here: http://www.necdisplay.com/p/desktop-monitors/ea244...
