Color uniformity / Luminance
Uniformity varies for tiles of the same production, so always take its values for a trend. We generally want a color variance of less than five on a 24/27 inch display. The Canvas 27Q gets a mixed score, with heavy color degradation at the bottom of the screen, above 6.
Luminance uniformity is generally expected with a maximum score around 10%, but the larger the screen the more difficult the task. The NZXT Canvas 27Q shows a maximum of 10%. This is a good result.
