If it works for you - I will update the link above.

Working great for me. One question about dithering. My setup is kodi limited - xrandr full - tv limited and I was reading this by that madvr guru guy madshi:

It is true that with a prefect color neutral grayscale, letting madVR render to 16-235 means that madVR doesn't have to dither. However, even black & white movies are usually not 100% color neutral. They often have a slight color tint. And as soon as chroma is anything but exactly color neutral, madVR instantly has to dither. Which is the case for 99.99% of all movies out there. And once madVR dithers, it shouldn't matter too much whether you configure madVR to output PC or TV levels.

Yeah, sure, in theory having madVR output 16-235 should be slightly better. But in real life I don't think there's much of a difference between 16-235 and 0-255 output. Of course 16-235 allows the preservation of BTB/WTW, which might be a plus because some displays might be calibrated to show a tiny tiny bit of BTB/WTW or something.


I know this isn't madvr, and that we shouldn't get anal about everything, but should one perhaps enable dithering even when sending limited range to tv from kodi? Or I might have misunderstood this completely.
