Illumination / Uniformity / Brightness / Black Level

To measure uniformity we define a matrix with 15 measuring points. The point in the center defines 100% brightness and based on that we calculate deviation in percent. Luminance is measured with brightness sett to its maximum. The black level on the other hand is measured with the brightness set to the minimum. To measure the brightness, we're using a Voltcraft LX-1108. The contrast ratio can be determined by dividing brightness by black level.

Uniformity of the VA panel used for the SE790C is average. In the center, this panel is notably brighter than on the edges. On the outside deviation in percent doesn't surpass 15%. If we include the three measurement points in the center we see a maximum deviation of 29.02%, which is visual to the human eye.
