AOC 90-series review: business-like and nice for home

Excellent price-performance ratio and modern design

Uniformity

The uniformity of the backlight with a completely white image is one of the strong points of the AOC Q2790PQU - the measured values are of the highest level. The full hd family members end up a bit lower, but still have excellent scores.

With a completely black image we see different results: the I2790PQU does manage to perform well, but the I2490PXQU and the Q2790PQU end up at the bottom of the graph. 

Uniformity details

The question is, how bad is that mediocre uniformity of black? In order to find out we placed the Q2790PQU in a dark studio, let it show a dark image and took a picture of it. On this picture you can see what we saw in the studio: some backlight bleeding in the bottom left corner. We also measure the lowest black value there. The I2490PXQU shows the same image. Is this a problem? In our opinion not for the main purpose, but if you are watching a 2.39:1 movie in the pitch dark it could be annoying. You should bear this in mind. 

AOC Q2790PQU

You can find the sub measurements of all three models below. 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 sub 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.
