BRIGHTNESS UNIFORMITY
Ideally, screen brightness and colour should be uniform
Any given colour and brightness level should look the same across the whole area of a monitor screen. For example, if you fill the entire display with a particular shade of grey or solid colour, it shouldn’t look brighter in some areas than in others, and the colour shouldn’t vary. These charts show the results of our lab tests, and how colour accuracy varies across the surface of each screen, measured at a brightness level of 50 per cent. Higher scores indicate a greater deviance (Delta E) from the correct colour value.
