A video display device includes LED pixels, a memory, and a processor. The processor receives video data that includes video pixels that correspond to the LED pixels. For at least some of the video pixels, the processor calculates a viewing angle for the LED pixel based on (i) a 3D location and optical axis vector for the LED pixel and (ii) a 3D location of a viewer of the LED pixel. The processor calculates a gain factor for the LED pixel based on the viewing angle and a relationship between pixel intensity and pixel viewing angle for the LED pixel. The processor calculates a compensated brightness for the LED pixel based on the gain factor and a brightness of the video pixel. The processor causes the LED pixel to emit light having the compensated brightness.
