Results: Viewing Angles, Uniformity, Pixel Response And Input Lag

The E232WMT's glass touch layer creates an additional variable, which affects off-axis image quality. It’s an IPS screen though, so the shift in luminance and color is small. To the side, you can see a blue tint and a drop in brightness. From above, the color goes a little green, while shadow detail is crushed. Overall, NEC still exceeds the performance of a regular TN monitor. It'd be easy to conclude, then, that TN technology is a poor choice for touchscreens.
Screen Uniformity: Luminance
To the eye, black uniformity is decent. However, our meter reveals hotspots in the upper-left and center of the screen. In case you’re wondering, the touch layer does not cause image distortion when it's pressed. Rather, the surface is quite solid, sitting high enough above the TFT layer to prevent contact.
Here’s the white field measurement:
The E232WMT’s white field uniformity is excellent, matching some of the better displays we’ve reviewed. I didn't see any issues with it whatsoever. Our measurements show slightly elevated levels in the lower-right corner of the screen, though.
Screen Uniformity: Color
Color uniformity registers a near-invisible 1.66 Delta E. In fact, only three of the nine zones measured a result over one.
Pixel Response And Input Lag

A 23-millisecond draw time puts the E232WMT slightly ahead of a typical IPS display. Visually, there isn’t a difference in the blur level, but the number above does positively affect the overall lag result below.
And here are the lag results:
We were pleasantly surprised to see the E232WMT post a lag result in 60 Hz gaming monitor territory. While we don’t expect gamers to flock to this or any other display emphasizing touch input, you should still get decent responsiveness from it in fast-paced titles. You’ll want a higher native refresh rate or G-Sync technology for top performance. But this NEC acquits itself well.
