Also, you said that if the output is 16-235, you get grey black or washed white. And in my case, the black that I get in the image (level 0 without enabling ffdshow's levels filter) is just the same black as the physical frame of my TV (which is absolute black). I tested it turning off the lights of the room, and doing that I'm not able to say where the image ends (a video showing level 0) and where the TV frame begins, so it's the same black.
Question is: Having that absolute black at level 0 with Full RGB doesn't mean that I have a 0-255 output? I think it does. Am I wrong?
I cannot answer your question, sorry.
The brightness and contrast change the luma curve, and it's possible to display 0-255 even your display only take 16-235 input. When you do the test, what input mode did you select from your TV? Please try to select RGB 0-255 and reset brightness/contrast to default value (you should write down the optimal value before doing this). Then try to switch between RGB full and RGB limited. If your graphics card can output RGB full range without problem then what you should see is:
1) With RGB full, luma is correct.
2) with RGB limited, you get grey black.
The theory behind this test is:
1) When your TV is set to receive RGB 0-255 and you choose RGB full output, the luma should not be compressed and it should look correct on your TV
2) When your TV is set to receive RGB 0-255 and you choose RGB limited output, the luma is compressed by graphics card and as a result, black is
raised to 16 and white is lowered to 235. In this case, your TV is still expecting black at 0, therefore it considers 16 as grey.
If you see a difference, congratulations, your graphics card outputs both 0-255 and 16-235, and you should choose 0-255 (RGB full) and let TV to cut BTB/WTW (RGB 16-235) and adjuest contrast so that you get some white above 235. For me and most other people, both RGB full and RGB limited output the same compressed YUV 16-235.
