We measure the uniformity in multiple ways, although however we look at it, the GB2783QSU-B1 does not perform all that bad. The uniformity of white is clearly better than that of black, although the latter is still ample.
Below you can find the uniformity measurements of the different models in a graphic view. These show, from left to right, the uniformity: uniformity of black, uniformity of white, contrast, colour temperature and DeltaE colour deviation compared with the middle.
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.
The biggest deviations are clearly seen in the upper right corner: in practice you will not notice these variations all that much.
