LG 27UD59 review: successor of inexpensive 4K monitor tested

Good and inexpensive choice even less expensive

Uniformity

As far as uniformity is concerned, the results for white are somewhat lower than what we saw with the LG 27UD58, but the results of the newer model are still fine.

  • Lowest compared to highest white
  • Average compared to highest white

LG 27UD59-B

The 27UD59 significantly outperforms the previous model when it comes to the uniformity of black. 

  • Lowest compared to highest black
  • Average compared to highest black

LG 27UD59-B

Below you can see all the sub measurements in one overview. 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 grey.
