@Asmodian: Neither 4:2:2 or 4:4:4 appear when displaying chromares.png (nvidia set to 1080p, RGB at any bitdepth). There is some slight horizontal lines where 4:2:2 would appear.
@Warner306: I presume you are refering to the discussion over at AVS with madshi on the Madvr HDR to SDR mapping thread? |

Is that your native resolution? You need everything at its native resolution, the image in a window if necessary.

@Asmodian Sorry - thought you meant the native res of the PNG. The JVC x7500 takes a native 4K signal but it uses e-shift to display a 4K image (native 3xDILA 1080p Panels). Anyway with UHD RGB I can see both 4:2:2 and 4:4:4 but 4:4:4 is darker. The tint also changes between 8 and 12 bit with 12 Bit looking Pinker and 8 Bit looking Red.

Make sure you use DDU in safe mode and select clean installation before installing 385.28. You want every trace of the newer driver to be removed.

Yup done that (DDU in safe mode) and it is looking good using what you just posted (just running a UHD BD now to check the frame repeats). The only stuff that I guess will not work is titles like Billy Lynn (UHD @ 60p with HRD). I've read the JVC Calibration thread and got the Spyder5 Ultra ready to go now that the basic config seems to be working well - Thanks for the clear post all in one place

try the sharpness settings out like said before. seeing both is a clear indicator of subsampling and most likely sharpening looks like newer ones use 1080p native not 1960x2160 native so they have to shift more to get to the same result but if done correctly it is the same as a native UHD image just less bright. the sub sampling test should work at 1080p too. |

If i have a rec709 lut in the rec709 slot along with pass HDR through to display checked (full HDR compatible video chain) will madVR ignore the lut when playing 4k HDR? I only want the lut active when I am actually watching rec709 content and not when watching 4K HDR.

The OSD will indicate if and which 3DLUT is being used, easy enough for you to confirm.

Hey guys. I've noticed a problem with my madvr setup and I was hoping someone had some insight for me.
I have a 144hz monitor and while using madvr and xysubfilter I was getting dropped frames the first time subtitles were displayed. It always happened at the exact moment the first subtitle was shown and never happened afterwards, nor did it happen if I rewound to the beginning and watched the same scene again. I changed my refresh rate to 60hz and the problem went away, so I assume this has something to do with that. I also tested at 120hz and I did not notice a problem. Now I'm not sure if this is actually a madvr problem or an xysubfilter problem seeing as it only occurs with subtitles and also doesn't happen if I switch to the internal subtitle renderer in mpc-hc. I also don't get this problem if I playback with mpv, but obviously that doesn't support madvr. Thanks for the help. |

showing subtitle the first times add the hole process and it looks like all buffered frames have to be re rendered. dropping frames in this case it pretty "normal".
thsi should only affact aasfilter mod and xy subfilter. i can't remember it but i'm pretty sure i brought this up a couple of years ago. |

There is an OSD bug that shows the SDR 3DLUT being used even with using HDR passthrough, but the 3DLUT is not actually being used (a test 3DLUT that should change the image a lot does not show any effect). The SDR 3DLUTs are only active for HDR content when madVR first converts HDR to SDR by either method.

I came across something strange while letting madVR upscale a cute little 240p movie to 4k resolution. Please have a look at the following output:

EDIT: I have also a second question. Isn't it possible to apply pixel shaders while using D3D11 copy-back decoding? mpc-hc says it can't use pre or post resize pixel shaders and I simply don't know why. Last edited by waldnebel; 7th July 2018 at 19:56. |
