Sceptre X270W-1080P Review: A Value 27" That Delivers

Brightness Uniformity - White

In addition to the performance a center, we’ve also added 9-point testing for brightness, both white and black. This is done the same way we measure color uniformity, except we only care about measured intensity. We set the monitor through OSD controls as close to 200 nits as possible, and then measured those 9 points.

Brightness Uniformity - Black

Our plots here do exaggerate differences, but there’s a fairly linear falloff in brightness from right to left across the display as measured. I tested this three times because I couldn’t believe it. Using the monitor, I couldn’t perceive any brightness irregularities at all; it seemed homogenous. If anything, I would’ve said that there was a tiny strip of brightness fall off in the vertical direction, not horizontal, but numbers are numbers. The standard deviation across the monitor here is on the order of 17 nits, for an average of 193.7 nits. It’d be nice to see a bit more uniformity, but it definitely isn’t an issue.

For blacks, there’s a central depression and a bit more brightness at the left and right edges, but then again in practice I never was disturbed nor noticed. Note that the standard deviations here are on the order of 0.035 nits which is pretty darn tiny. Moreover, we’re at respectable black performance to begin with at an average of 0.36.
