Hi,
I've got a GTX1070, Sony 4k TV and Pioneer LX59 AVR capable of Ultra HD Pass-through with HDCP 2.2 (4K/60p/4:4:4/24-bit, 4K/24p/4:4:4/36-bit, 4K/60p/4:2:2/36-bit), using Windows 10 last update. If in nVidia settings I set the desktop to RGB Full 8bit everything works fine. If I try to set it to ybcr 422 12bpc (or 10) the green on desktop looks really pushed and if I play MPHC+madVR fullscreen the movie looks black white and green, no other colours. If I don't play it in fullscreen it's fine (but shows 8bit). I read that with my config and content (fullhd and 4k) it would be better to go with YBCR 4:2:2 12bpc but I got this problem and I'd like to solve it even if don't know why. Tried to change HDMI cable, that was already good, and nothing changed. Any idea? Hope so....thanks! |

I'm sure this bug/issue will be fixed at some point, but it may be low on his priority list. Nevertheless, madVR 1.0 will have to work well on Win 10 because so many people are using it, so we just need to be patient. Last edited by jkauff; 1st December 2017 at 13:03. |

RGB 12-bit can be done at 24Hz just fine, just not at 60. Additionally, you should always prefer RGB 8-bit over YCbCr 4:2:2 10/12-bit. With proper dithering, chroma is more important for image quality.

That makes sense, however the creators update is likely to be the last free major update so we could do with getting everything working with that, then we can all just sit on that version, there is too much missing in the way of features on pre 1709 versions, connect to mobile for one is essential for me. yup, we'll all just have to be patient, in the meantime I think i'll image my curent C drive and dual boot 1703 and 1709 so I can retesting MADVR with each new release whilst having a stable platform to use in the meantime, I can live with some of the issues with creators update but I cant live with frame drops every 40 seconds, I couldnt solve that whatever I did and thats really odd as I get the same problem playing HDR movies on the pre creators update, these issues are connected somehow, hoping the issue will be spotted and fixed soon. Note however on creators update HDR was fully working for me using exclusive mode, it even triggered HDR on my LG OLED, just couldnt live the frame drops, so close yet so far.... |

I can confirm this did the trick, madVR's display settings need to be set to 10 bit panel. But in fact, exclusive mode is still required, not just fullscreen. Thank you very much, madshi and huhn.

so to sum up, people on the fall creators update using AMD card have the following problems:
PROBLEMS (A) - black screen on newer version of MADVR (B) - frame drops ever 40 seconds regardless of what versions of MADVR, LAV or AMD drivers are used - reclock also does not resolve this. WORKING (A) - using 0907 MADVR HDR works and triggers HDR mode on passthrough but has frame drops every 40 seconds (B) - using 0907 SDR works but with frame drops every 40 seconds (C) - using 0907 MVC 3D using FSE mode works but with frame drops every 40 seconds. So if we can find away to fix the 40 second frame drop and then fix in V1.0 what got broke in V0908 onnwards we could be there for AMD users. |

I guess Il will try to convince myself with doing the hardware decoding with my RX560 which has only 55% load by 4K Interpolation. And see if I get any benefit for the GTX1080TI and rendering time in Madvr. It seems smarter that way to me. Currently I am doing: 1) Hardare HEVC decoding: GTX1080TI 2) FI 4K24p-->60p: AMD RX560 with bluesky FRC 3) Rendering madvr: GTX1080TI Maybe if Decoding speaks directly to the Fi on the same card, it would be better. |
