NEC E232WMT 23-Inch Touchscreen Monitor Review

When Windows 8 added 10-point multi-touch support, we expected a flood of desktop touchscreen monitors to hit the market. That hasn’t happened yet but NEC is making maximum effort with the E232WMT. Today we check it out in our lab.

Results: Color Gamut Accuracy

For details on our color gamut testing and volume calculations, please click here.

We’re showing you the same three configurations as on the previous page: Native, sRGB, and calibrated modes.

The factory default Native mode isn’t too bad, but there are hue errors in magenta and yellow. The 20-, 40-, and 60-percent saturation levels are also below their targets. As the measurements move towards the edge of the gamut, accuracy improves. This means the brightest images are more color-accurate than darker ones.

In sRGB mode, things are much better. There is a little over-saturation in blue and hue errors in cyan, but red is much-improved, while magenta is closer as well. Luminance levels are also near-perfect except for 100-percent blue, which is 19 percent too high.

Calibrating User mode produces the best gamut result by far. There is still a hue issue with magenta, but all other colors are close to their targets. Luminance levels are land in a tight pattern with the exception of red and 100-percent blue. These are minor errors, however. Overall, color performance is excellent.

Now we return to the comparison group:

We expect a professional-grade display to break the one Delta E barrier. But a business or gaming monitor should have a maximum average color error between one and two. The E232WMT is well within that range, and it’s right in the middle of the group.

Gamut Volume: Adobe RGB 1998 And sRGB

The E232WMT comes pretty close to full coverage of the sRGB gamut with 97.69 percent. The gap comes from a slight hue error in the green primary and a little under-saturation of cyan.
