![]() ![]() There is no data below 0 or above 255 with an 8-bit video signal as there are only 256 possible values. PCs are different and use a range from 0-255. You should always use the RGB Limited setting with a TV. RGB Full will display video games and other 0-255 content at the correct 0-255 range. With TV and Movies, it leaves them untouched because they are already in the 16-235 range. With regards to RGB Full or Limited, 'Limited' refers to the values being 'limited' to 16-235 and not the Full 0-255 scale. For HDR gaming, simply turn on HDMI Ultra HD Deep Color for the HDMI port that you connect your gaming console to on the LG 27" Class 4K UHD IPS LED Monitor with HDR 10 (27" Diagonal), Model # 27UK600-W and select HDR Game in the Picture Mode settings. ![]() Where 4:2:2 comes into play with your gaming console is using it for Blu-Ray support and gaming on displays that are true HDR10. Unless checked, your gaming console will be outputting at 4:4:4, with zero compression and 8-bit displays are able to handle this and will receive the full beauty of the signal. Most gamers should therefore not worry about it. The 4:2:2 signal will have half the sampling rate horizontally, but will maintain full sampling vertically.In video games, while some PC games that have a strong focus on text might suffer from using chroma subsampling, most of them are either designed with it in mind or implement it within the game engine. Chroma 4:2:2, on the other hand, is a 4 x 2 array of pixels and has half the Chroma of 4:4:4. A signal with a Chroma Sampling of 4:4:4 has no compression and it will transport both luminance and color data. You may be familiar or have seen a Chroma Sampling of 4:4:4. ![]() ![]() (YCC is YCbCr)This reduces the bandwidth without significantly affecting the picture quality. A: Answer The checkbox in your Xbox One X for YCC 4:2:2 is for the Chroma Sampling which is a type of compression that reduces the color information in a signal in favor of luminance data. ![]()
