NEC EA244UHD Review

AdobeRGB Test Bench

Pre-calibration the NEC AdobeRGB preset is still good but not great. Unlike sRGB the grayscale has a blue-tint instead of a red one. The gamma has the same roll-off in it, and I expect we will see this a lot going forward. Color Checker and Saturations are both very good pre-calibration with most of the issues at the lower light output levels due to some gamma issues. The color points also seem to indicate that we have the full AdobeRGB gamut here.

Post-calibration at 200 cd/m² the grayscale moves to being almost perfect. The gamma is very flat and virtually every grayscale point has a dE2000 below 2.0. The color checker average has fallen to 0.644 and the saturations dE2000 has fallen to 0.77 on average. Again the post-calibration numbers for 200 cd/m² are just about perfect.

Calibrating to 80 cd/m² the results are just like sRGB: very good but not as good as 200 cd/m². Everything is improved, from grayscale to colors, and it measures very well. There isn’t too much to say when there aren’t any large performance issues to be found.
