Anyone knows why 4K60p RGB 8bits Full would give a magenta tint when playing a video with MadVR, while 4K30p RGB 8bits Full or 4K30p RGB 12bits Full would give the correct colors? 4K60p YCC 4:2:2 12bits give the correct colors too (4:4:4 isn't possible due to bandwidth limitations).
As I set the nVidia panel to 12bits RGB in 30p, the bit depth goes blank when playing 60p (it does send 8bits automatically to fit into the 18Gb/s bandwidth limitation of HDMI 2.0), so I tried to force the output to 8bits at 60p (8bits showing instead of blank in the nVidia control panel) and I get the same results. I checked and it's not a wrong colorspace selected in the projector (whether I select RGB or YCC instead of Auto the colors are wrong at 4K60p in RGB).

I think I've got my setup pretty well dialed in at this point. I may mess with it more cause that's how I roll, but, I'm watching Revenge of the Sith right now and the quality on my 1060 is phenomenal. I very much like NGU AA High for Chroma upscaling. Since it's blu-ray I don't have any other scaling active at the moment. Using the D3D11 decoding in LAV nightly. Very pleased!
(What I've changed recently is turning on pure direct on my Panny plasma and setting everything to RGB FULL. Working great!)

Your GPU is too slow for your settings if this happens. Its 60 fps content, rendering times over 16ms are too high.

Same clip here (albeit my clip reports HDR 1000nits) on a 1080ti using DX11 Native and NGU AA med for Chroma @ 11ms render times. K Last edited by oldpainlesskodi; 19th September 2017 at 09:13. |

Guys,
Need your thoughts. Using MPC BE I get perfect sync for my display 23.976hz using madvr custom refresh rates using 10bit & 8bit However, Using DSplayer I only get perfect sync using 10bit. if I set madvr display output to 8bit, refresh rates is only 23.970. This results to frame drop every 3 minutes

Quoting is at 90% misused
[IMG] is often useless and destroys formatting, and quoting a big image is disrecpectful. And for your question, luma is downscaled because if you look at this enormous image, you'll notice he is in window mode. @el Filou: you can test D3D11VA deinterlacing with mpv if you're really interested, but not to be discussed here. |

@oldpainlesskodi : it was superfluous because the (massive) image you quoted can be found literally 3 posts above

treat 25p movies as 24p (requires Reclock or VideoClock): [Disabled] Uses 24 Hz modes to display 25 fps content, it requires Reclock or VideoClock to slow down the audio to match.
hack Direct3D to make 24.000Hz and 60.000Hz work: [Disabled] A hack to Direct3D that enables true 24 and 60 Hz display modes in Windows 8.1 or 10 which are usually locked to 23.976 Hz and 59.940 Hz. May cause presentation queues to not fill. I'm on Windows 7, where can i learn about these? What means "treat 25p movies as 24p" etc.? Don't know what nomenclature are.
