The new viewing angle measurements are a lot more detailed than before. Aside from the reduction in brightness we also measure the colour deviation. The standard deviation is shown once again. 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. Unfortunately we have not tested enough monitors to be able to put these values into perspective, which is why we show the information here without linking it to a conclusion.
Because this test is performed differently than the test we used to do, these results are not comparable with those of the older test method. For this test we measure at a brightness of 150 cd/m² instead of using the maximum brightness, and the distance between the device and the screen is different.
The Eizo EV2456 achieves very good results for horizontal viewing angles: the remaining brightness, colour deviation and standard deviation are extremely good. Only the Asus BE249QLM performed marginally better. Vertical viewing angles aren't quite as good though - they're rather average, as you can see in the graphs. This can also be seen in the screenshot on the bottom of the page.

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