With the choice for and way of mounting and setting the backlight a manufacturer can make quite a difference. The more uniform the lighting, the better. The AOC Agon AG352UCG clearly performs better than the Acer Predator Z35P when it comes to the uniformity of white, which is mainly lacking in regard to the ratio between the lightest and darkest measured panel part.
With the uniformity of black all three models with a 35-inch AUO-panel have it more difficult, but it is the Acer that shows the best result. Do bear in mind - we cannot say this enough - that the absolute differences between the 15 sub measurements are a lot smaller than with white, and the seemingly big relative differences are less visibly annoying in practice. In practice the difference between the most black and least black part is 0.04 cd/m² for the AOC and 0.03 cd/m² for the Acer.
Below you can find the sub measurements of both monitors. Note 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. Here you can clearly see that both models have very comparable uniformity characteristics.

Uniformity AOC Agon AG352UCG
- 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.
