Color Gamut And Performance
For details on our color gamut testing and volume calculations, please click here.
In the XB270HU's Standard mode, we see good accuracy in the color saturations, but there are a few hue issues in the secondary colors, especially magenta. Since the gamma is where it should be, all that's needed to fix things is a grayscale calibration. Bringing the white point in line will pull the secondaries onto their targets and firm up the luminance levels too.
The XB270HU omits the color management system found in the XG270HU but obviously it's not needed here. Every color is on target for both saturation and hue, and luminance levels are near perfect. Aside from a slight over-saturation in the red primary, this is an excellent chart.
Now we return to the comparison group.
Since the Overlord Tempest was calibrated through a LUT, the XB270HU is the winner of the calibrated-by-OSD competition. Only an expensive pro-screen will post a better result than this. Its color accuracy obviously outperforms most gaming monitors.
Gamut Volume: Adobe RGB 1998 And sRGB
If gamut volume is an important metric in your work, then the XB270HU offers a little bonus red bringing up the total to over 107 percent of sRGB. The Monoprice sits atop the ladder thanks to its Adobe RGB gamut, which may not be ideal for gaming or entertainment purposes.
