I have bought a PS4 Pro and I am trying to get it to work with a 4K Tv. Having checked the video settings in the PS4 menu, there are 2 different options for rendering 4k. What is the difference between YUV420 and RGB, which is better and what one should I choose? I have a Sony Bravia 4K TV and both options seem to be available for me without any detail as to the difference between them.
4K and HDR are great, but at the moment there are not proper standards, which means everyone is doing their own thing and it doesn’t conform to any set standards. From what i can gather YUV420 is for HDR video. If you have a HDR 4k TV then this is likely the best one for you to set it to. RGB is the safer option without HDR. It may not look as good, but it is the safe option.
People suggest that you actually pick a setting rather than set it to auto. Due to the lack of standard the PS4 has trouble using auto. Your TV might have HDR, but it might not have some things the PS4 checks for in the signal and it will trigger the PS4 to use the RGB setting which could result in a reduction in quality.
I would like to say that I am no TV expert. I am just writing this based on what I have been able to discover from reading articles and watching videos. There have been situations where some articles completely contradict what I say here, but for the most part, it seems like what I have written about above for the 2 different 2160P settings on the PS4 pro are correct. Go with YUV420 if you have a HDR TV.
