We do not have anything to complain about when it comes to the uniformity for both the Benq Zowie XL2735 as well as with the XL2540. Both in comparison with the brightest white part (where the middle is set at 150 cd/m²) as well as in comparison with the average, the part of the screen with the lowest brightness is not all that less lit. The XL2540 performs slightly better than the XL2745 in terms of uniformity.
With the uniformity of black the absolute differences are always very small, which means that the values should not be taken too heavily. Something further down you can find the differences in absolute numbers. The XL2540 performs remarkably well, while the XL2735 is slightly less uniform.
Detailed measurements uniformity
Bear in mind that the colour in the boxes with the uniformity of black, white and the contrast is related to the results of the measurements for that model; not to the absolute values.
- As far as black goes, the lower the measured value, the better (=greener); if the value is higher this means worse (=redder).
- For white the colour coding is different, because there we set a specific brightness of 150 cd/m². That is why values that are closer to this setting green, values that are further away become red – the more they deviate the redder they are.
- As far as contrast is concerned, the highest contrast is green, the lowest is red – the values in between are marked by these colours. Greener is better, redder is worse. We emphasize again that these values are relative: a contrast of 1702:1 is excellent, but if the highest measured contrast is 2581:1, the former value is still marked in red.
- With the colour temperature the measurements are bluer the lower they are, yellower the higher they are.
- Last but not least the colour deviation: here you see a number for the DeltaE value in the boxes, where values below three are barely noticeable with the naked eye. The colour of the boxes shows the colour deviation of gray.
