In terms of uniformity we expect top performance in this class and it should be said that none of the models perform worse than 'good', especially if we look at the more important uniformity of white. Eizo is traditionally strong here, but Dell manages to perform even better. As we have stated in the past, the uniformity of black is of less importance because the values are a lot closer in absolute sense which means you do not notice the differences as easily. Despite that we see clear differences here, where Eizo drops and HP manages to take a strong second position.
Below you can find all the detail measurements for the 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 for black: 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.
