The uniformity, or the evenness of the backlight of the lcd, is remarkably good for a monitor of this size. It is usually a weakness of superwide monitors, but the led strips on both sides apparently use an advanced diffuser. The lowest measured white value has 82% of the brightness of the whitest white: a solid result. The average is good as well with 89%. With black the C49HG90 shows its true strength, because there it is in the top three in the graphs, and it is often with black that monitors have difficulty performing well.
Below you can find the sub results of the uniformity measurements.
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.
