Color gradients are reproduced with barely visible banding.

The viewing angles are rather good – for a TN matrix. The screen gets darker when viewed from below, but that’s not a big problem. Yes, the LCD2470WVX won’t be a good choice if you need really wide viewing angles, but most users are going to be satisfied with this parameter. The monitor is also free from color distortions such as I saw on the LCD24WMCX: the contrast ratio is the only parameter that degenerates on your deflecting your head from the center of the screen.

The monitor’s color gamut is quite ordinary, similar to the standard sRGB color space.

The average uniformity of white brightness is 4.0% with a maximum deflection of 19.4%. On black, the numbers are 3.1% and 16.2%, respectively. That’s a good result although the darker top right corner has spoiled it somewhat.

The gamma curves don’t look good at the default settings, going far from each other as well as from the theoretical curve. The contrast is set too high by default in many monitors from NEC. Reducing this setting even by 5% improves the reproduction of colors.

As you can see, the curves look much better at the reduced settings.

The monitor is slow as it lacks Response Time Compensation. The response time average is 13.9 milliseconds (GtG) with a maximum of 22.8 milliseconds.
