RGB和YCBCr444两种输出格式，是根据显示器的用途与所对应的硬件设备或软件所输出，使其显示器能准确以最佳的显示这些颜色。具体还是要根据的自己的需求来选择。颜色格式有四种选择情况：1、输出颜色格式（F）RGB，输出动态范围（o）完全；2、输出颜色格式（F）RGB，输出动态范围（o）有限；3、输出颜色格式...
RGB vs YCbCr444. 11 Nov 2012 Jan 2022 siveZ 12y Hello! I'm using dual-monitor rig and i just noticed some unknown to me option in NVIDIA Control Panel. I'm russian and i don't know how to translate this option correctly, but literally it translates as "digital color format" in ...
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...

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....

显示器面板最后是要转化成RGB工作的,也就是说你显卡用RGB那就是YUV转RGB,你显卡用YCBCR其实也一样是YUV转RGB,如果同样是444都是无损的。8bit如果你理解了,那么10bit也是一样的情况。只不过3个通道从256x256x256阶变成了1024x1024x1024阶。10bit和12bit的YUV信号一般都不是444,多数都是422或者420的,你可以...
