I can change between ycbcr444 and RGB in the Nvidia control panel color settings. In game, when playing in 4K, ycbcr444 looks exceptionally better than RGB. The colors pop and it looks much sharper. I am going to be using it over RGB obviously, I am just curious as to how they work and what makes one appear so much better than the other. Everything I have read on the internet isn't very clear on this and everyone makes it sound like the difference is negligible at best. Thanks!
