Proper RGB output levels are necessary when passing from PC to TV color spaces. When sending video via HDMI to a TV, in most cases, color spaces are set as follows:
(LAV Video) All Output Formats -> (madVR) PC levels (0-255) -> (GPU) Limited Range RGB 16-235 -> (TV) Output as RGB 16-235
madVR expands the source 16-235 signal to full range RGB leaving the conversion back to 16-235 to the graphics card.
Why should we do double conversion in films? What is the logic behind it if our TV does 0-255?
If i am not wrong with that configuration:
- films: 16-235 -> 0-255 -> 16-235 (two conversions)
- games, desktop, etc: 0-255 -> 16-235 (one conversion)
Shouldn't it better?
(LAV Video) All Output Formats -> (madVR) PC levels (0-255) -> (GPU) RGB (0-255) -> (TV) Output as RGB 0-255
Which means:
- films: 16-235 -> 0-255 (one conversion)
- games, desktop, etc: 0-255 (none conversion)
Am i wrong?
Most TVs won't do RGB 0-255, so that option isn't mentioned. If your TV does, then go right ahead.
I think most TVs nowdays do 0-255. Samsung, LG, etc. call it different (high, normal, low, etc ... black levels).
I think it is a mistake if your guide doesn't mention the best configuration for htpc. New users with TV that does 0-255 will configure wrong their GPU output.
