Video is pretty much all 16-235, but 0-255 is the ideal HTPC output mode since PCs operate in RGB color space which is alawys full range.Hey guys,
I just realized that I may have set up my video settings wrong all along.
In my Nvidia settings, I set up the output dynamic range to full (0-255). When playing a 4k HDR movie via my HTPC using MCP-HC + MadVR and always had the impression that the image was too dark. I played around with my LG C9 settings, managed to get the image a bit brighter and thought it would be good enough.
Today I played the same movie on Disney+ with Dolby Vision and on my HTPC and I could tell the image my PC output was too dark. So on my TV HTPC source I switched the black level to high and miracle I got the exact same image as with Dolby Vision (I consider the dolby vision image reference since all the settings are preset to be the most accurate by cinema standards)
I remember reading somewhere that LG low and high black level settings were in reality the equivalent of 0-255 and 16-235 dynamic range. Which leads me to wonder whether Blu Ray movies are meant to be played using the full or limited dynamic range?
Maybe I got it wrong all along setting up my HTPC to output full dynamic range and that the right setting for HTPC is to use 16-235 range?
If you tell the PC to output Limited range it will always be doing a conversion which is not the best quality.
You just need to set your display settings to properly show the full range output from your PC. You may also need to adjust your media player settings to the proper levels.
The most "ideal" settings for an untouched video output would be Limited - Full - Limited. Where the first Limited is your media player (set madVR to Limited), the Full is your GPU output, and the second Limited is your display's range setting.
The downside to this is everything that's not from a media player (like your desktop, web browser, video games, etc) will now appear washed out. So if this is important, the other setting that lot of people use which will prodice the correct levels for everything is Full - Full - Full. And there is only 1 conversion in there applied to video to convert it from Limited to Full and that happens in madVR which does it it in very high quality.
