Anandtech published NEC EA244UHD
A quote from the article:
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. Read on for our full review.NEC EA244UHD Review @ Anandtech
