what is ycc 422

YCC 4:2:2 is a color encoding system that represents digital video or image data. It is a method for compressing video that uses less bandwidth than RGB, making it a good choice for keeping older 4K screens compatible. YCC/YUV are the color primaries and 4:2:2 is the compression used. It is an option in the Xbox settings, and whether it should be enabled or not depends on the TV and the alternative option. If the TV does not support HDMI 2.1, enabling YCC 4:2:2 may provide a benefit. However, some users have reported shimmering or black level instability when using YCC 4:2:2.
