Hi, my TV is a 10 Bit panel HDR10, it supports full RGB, but when u go into HDR mode within a game, my ps4 auto switches to YUV422(HDR) it does this because it say "When Displaying 4K HDR Content at 60Hz, the colour format will be YUV422 or YUV20 instead of RGB due to HDMI 2. The AYUV format, which is a 4:4:4 format, uses 8 bits each for the Y, U, and V samples. Table of Contents. RGB la base du signal couleur Grâce aux 3 couleurs primaires (rouge, vert et bleu) il est possible de “fabriquer” toutes les autres couleurs. One huge benefit to storing images as YUV instead of RGB or CMYK is the ability to easily compress the image without losing perceived quality. For serial RGB operation, JP1 pins 1 and 2 (bit 0 on the PCB) should be shorted with a jumper. It is a valuable tool to assist development of games, video codecs, and general graphics programming.
