GPU driver configured to output RGB: LAV decoder output (YCbCr) → madVR (converts from YCbCr to RGB) → HDMI output (RGB) → TV (converts from RGB to YCbCr) → TV (converts from YCbCr to RGB) Only with PC Mode yo can avoid that conversion, but not always. In the end, with most TV, you can only choose where RGB->YCbCr conversion is done, through GPU or TV. |

Unless you put your TV into PC mode, it is almost certainly converting an RGB signal into YCbCr (and probably 4:2:2 or maybe worse, 4:2:0) to do all it's processing, and then converting again to RGB for final display. In PC mode, you may or may not avoid this conversion process - to use my TV as an example again, in PC mode, all of the stuff I don't use anyway is greyed out, leaving only the basic controls and the CMS, but I have no idea whether it's bypassing this RGB-YCbCr-RGB process, all I know for sure is in PC mode it passes the 4:4:4 test (if not in PC mode, it shows 4:2:2, a clear indicator that it's converting an RGB signal into YCbCr).

I did the 444 test and I passed it. And without PC mode (only HDMI) I also did the 444 test and passed it too... You say that the RGB signal arrives at the TV and then the TV converts it to yCbCr again? I'm already very confused again ...

You may find that in PC mode you are stuck with 60hz, and in any other refresh rate (like 23/24hz), the TV comes out of PC mode. It's really easy to get lost in the pursuit of absolute perfection though. What is subjective, what is objective, and what is plain placebo will always be up for debate, especially in this thread. Just try to spend some time actually enjoying some movies

I just want to know how to configure the HDMI options on the NV card. RGB or yCbCr444... I want to know which one is right.

Easy - RGB. And of course you can choose any supported refresh rate while in PC mode. The way to test it is put the TV in 60hz PC mode. Then in NV panel change to 23hz. Go into the TV settings and see if the stuff that gets greyed out in PC mode is now selectable.

it is WRGB RGBW or what ever you like more. that'S how LG oled work they have 4 sub pixel not 3 and one of them is white.
RGBA is RGB ALPHA. i'm pretty sure there is no screen with an alpha channel on the panel. |
