单纯从编码角度讲YCBCR要比RGB先进,因为YCBCR可以兼容黑白,同时也能近乎“无损"的压缩图像,因为可以单独分离亮度信息而只压缩颜色信息,你就算是写轮眼也很难出区别,近乎可以“无损”节约一半带宽。而RGB编码压缩就一定是有损的,可以很明显就能看出失真。 有UP主专门做过RGB和YCBCR 4:2:2/4:2:0的对比,这还不是对...

If I use rgb full or limited I can only do 8 bit dithered hdr. I'm able to get 422 at 1440 p with my GeForce 1070, but I purchased a vega 56 so I could have freesync and hdr. I've attached a few screenshots to show what's going on including a CRU screenshot. cru samsung....
