The NXG253R proved to be accurate out of the box with some upward potential. A few minor adjustments (see our calibration settings) resulted in a stellar image with excellent color, grayscale and gamma.
Grayscale and Gamma Tracking
We performed our tests and calibration in the NXG253R’s default User mode. Out of the box, grayscale errors were nearly invisible. If we looked closely, we could see a little extra blue from 90-100% brightness, but most won’t see these issues in actual content. Calibration is not required, but as you’ll see, it’s worth doing.
After tweaking the RGB sliders, we have just 0.39 Delta E (dE) average grayscale error. It doesn’t get much better than that. Though we measured a drop in contrast, the image looked a little more three-dimensional than before. We attribute that to tighter gamma tracking. Only a small dip at 10% brightness spoils an otherwise perfect trace. This is excellent performance.
The NXG253R starts out with a 2.19dE average grayscale error, which is better than all but the Acer in this out-of-box test. The monitor can be used without calibration. With adjustment though, it’s visibly better, which can be said about all the displays here. An average grayscale error under 1dE is a good thing.
The MSI’s gamma tracking is spoiled a bit by the dip at 10% brightness. That increases the range of values to 0.31, resulting in a last place finish. But the average gamma value is 2.21, making the NXG253R first in our deviation test.
Color Gamut Accuracy
The NXG253R is an sRGB monitor, so we performed all our tests using that reference. By default, color is mostly on or near its saturation and hue targets. Red is slightly undersaturated at 80 and 100% saturation, while blue is oversaturated throughout. Green and the three secondaries are right on their saturation values, and magenta is slightly off in hue. These are minor errors though. The average value of 2.27dE means you are unlikely to see the errors with the naked eye.
Our calibration settings reduced the average error to 1.87dE, mainly due to the tightening up of the secondary hues. All colors became closer to their ideal values. Though the difference looks small in the above chart, it was noticeable in actual content.
The top four screens in the first above, the 360 Hz monitors, all have very low color gamut errors. Considering their premium prices, that’s a positive. If you make the investment in one of the fastest gaming monitors currently available, you’ll be satisfied with color accuracy too.
Color volume is another matter though. Most gaming monitors these days include extended color. The 360 Hz screens do not. This test is one of the reasons we included the Viotek in the group. It’s certainly not as quick as the others, but it has the third largest gamut we’ve measured. The four 360 Hz monitors are all close in volume with around 110% of sRGB.
