Our viewing angle measurements show the brightness as well as the colour deviation. Aside from that we also show the standard deviation. This is based on the sub-measurements of the base- and support colours, plus 100% and 75% white. If the standard deviation is low, the brightness of all colours is reduced in the same manner. If this is higher, we speak of a colour shift.
The AOC Q2790PQU performs very well here, with excellent horizontal viewing angles and a limited colour deviation. The I2790PQU and I2490PXQU respectively perform well and slightly disappointing - the 24-inch model is not very good in terms of viewing angles. This is not an issue as long as you sit right in front of it, but the brightness loss from left and right is surprisingly high. The colour deviation is also higher than desirable.

Below you can find the deviations of white for the four viewing angles – the graphs above show the average colour deviation, which explains the different values.
