Finally have managed to dump a few of my UHDs and have a bigger sample set for hdr files to play with madvr. My main question is related to what is the right nvidia setting to set in the control panel. I have been using rgb 4k@60 8bit till now but I wonder if that's incorrect to playback 10bit files. When madvr switches to 4k@23, does it also set 10bit? I have tried looking into all my tv/avr settings and can't find anything that can confirm bitdepth and color format unfortunately.
I have set 10bit and above in madvr for the panel (Sony 75z9d). Should I set the control panel to YCbCr 422 and 10bit? I also have a file with 4k@60, 4:2:0, 10 bit HDR. Yes its a 60hz UHD. This one really confuses me since i know rgb 4k@60 10 bit wont work over hdmi. So somewhere its either getting converted to 8 bit or a lower chroma? It plays fine and looks very good to my eyes, but I 'need' to know if some unnecessary conversion is getting done somewhere. Madvr OSD says P010, 10-bit, 4:2:0 but I am not sure if that's what the GPU is finally passing to the panel? Card is nvidia 1080 (385.41), latest madvr + lav filters. I am using FSE and madvr auto switch resolution for 4k@23, 4k@24, 4k@60. DXVA copyback in LAV. Also I would like to say that I think my pc with madvr has a much better picture than my uhd player. Thanks madshi. Last edited by austinminton; 13th October 2017 at 04:41. |

A couple of things I learned:
All of this may not be necessary for everyone, but it worked for me on Win 10 Creators Update and the latest Nvidia driver. No more "The GPU has rejected this mode for some reason" errors. The custom modes work perfectly, and I LOVE the results! Last edited by jkauff; 13th October 2017 at 11:32. |

That would be up to the video player how it manages its window dimensions.

I really preferred the previous Adaptive Sharpen, the new one enhances grain/fine detail too much and may alias edges more then the previus one. Hopefully ramped-up LumaSharpen and the new AS are similar enough switch back AS... or some compromising words to get the previous one back.

If I remember correctly, madVR should switch to 10/12bit if you switch to it manually once... I could be wrong... Quote:

Dear Friends
I have Epson EH-TW5300 projector and I watch UHD movies via MPC-HC + madVR + LAV Filters. As you know there is HDR and BT.2020. My projector isn't 4K and HDR, but movies with 2160p looks better then 1080p. My question is about madVR Settings > HDR, I mean which one should I use to have optimal experience and quality: 1. let madVR decide 2. convert HDR content to SDR by using pixel shader math 3. process HDR content by using pixel shader math When using option 1, I have darker colors, when 2 bright colors and 3 washed out colors. Which one is the most similar experience to real HDR effect? I am confused... Thank you in advance for your support. Sincerely |

I am bit surprised about 1 not looking the same as 2. Last edited by Pat357; 14th October 2017 at 00:22. |

It does, unless your screen supports native HDR (or at least claims to). Of course specifically selecting option 2 unlocks the fine-grained HDR controls, so maybe those aren't identical to the ones in auto mode.

After more testing, RCA@1 is fantastic for low-res hopeless files that could use some smoothing anyway but indeed a far lower value would be ideal for files that come with both details and blocking. Anywhere between 0.1 and 0.5 might do the magic for those blocky and yet not quite hopeless videos

With madVR v0.92.6 I often get video player freezes when launching another DX11 application, like a game.
I'm using MPC-HC Nightly, Lav filters nightly with D3D11 Automatic (Native). Video freezes but audio keeps playing, also d3d11 native switches to d3d11 copyback in lav filter video decoder window setting. |
