Can someone please help me ensure my 4K HDR settings are right for my LG C9 OLED TV?
- Do I want the drivers and the TV both set to "HDMI RGB Full"? - Do I need to manually enable 24hz 12bit in NVIDIA drivers prior to watching HDR content? This setting seems to revert to 8bit whenever I swap back to 60hz 8bit and restart the computer. Maybe I need to make a bat file or something to make this switch automatically when I launch Kodi? - Do I want to select 24hz or 23hz in the NVIDIA drivers? Thanks.

If it's really a movie it should be 25 fps, not 50. Are you sure it's not a video like a documentary or TV studio programme? If not, check if some setting is not forcing deinterlacing and creating 50 fps out of your movie. 50 fps puts 2x more stress on the GPU for rendering so if not using profiles it's possible your settings are fine with 24p but not with 50i/p. Post a screenshot of madVR's OSD during playback to some external image hosting site so people can find out what's wrong.

Video: H.264/AVC 1920x1080 25fps [V: h264 high L4.1, yuv420p, 1920x1080] And you are right it looks like GPU (2070 Super) is doing twice the job. Thanks for help Last edited by Harumi; 1st October 2019 at 21:07. |

I have a LG 32UD99-W monitor which is supposedly HDR. Could you please tell me what settings in madVR I should choose?
in hdr if I set to let madvr decide or passthrough HDR to display, my monitor goes to black and only restarting my PC I can have the monitor back. For the moment I use Tone map HDR using pixel shaders. What are the best settings for this HDR monitor? |

@Harumi did you pause playback before taking the screenshot? You have to take it without pausing to get really precise stats for the queues, but it's already showing 27 ms avg render time which is too much indeed.
It says the source is 50 fps so it's probably being deinterlaced in the decoder filter. Do you maybe have any other processing options active (enhancements/artifact removal/scaling refinement? If yes then disabling some can help.

What are these suppose to be for 4K BD HDR content on an LG OLED? https://i.imgur.com/JXe5UeH.png
I can select 4k24hz 12bit RGB or 4k60hz 10bit/12bit YcBCr422. However, they don't stick when I switch back to 4k60hz 8bit RGB and restart the computer. So I am unsure how this will even work without adjusting the setting depending on what i'm doing? If I just use NVIDIA default, it seems to only use 8bit RGB full: https://i.imgur.com/gYFBIUA.png Last edited by saracas; 2nd October 2019 at 00:16. |

I'm having stuttering issues with Direct3D 11. The motion is much smoother with DX9. Strangely, enabling Error Diffusion with DX11 makes the stuttering unbearable. If I use DX9 there's no problem but I'm losing 10-bit output for HDR, right?

I have been a big fan of NEDDI3 since it was only available in Avisynth and even 64 neurons rendered way less than real time on my CPU. I now use NGU AA by default. Some content really benefits from NGU sharp but usually NGU AA or NEDDI3 seem more natural to me too.

Will do. But would lt really hurt to add NEDDI3 back for luma though?

NNEDI3 was the only algorithm using OpenCL, which meant a lot of infrastructure around that in madVR, nevermind that the OpenCL stuff also caused a few problems on its own - so yeah, there is a potential for hurt to keep it.

isn't the shader version fast anyway?
NGU AA replaced nnedi3 because it was doing the same job just better. there was one image(very low resolution and quality anime) that was tested where it could be argued that nnedi3 was better then NGU AA the rest was generally seen as even or a clear improvement. |

@el Filou
Yes, I managed to find the problem, it was the LAV decoder filter. The deinterlacing mode was set to auto, and that doubled my refresh rate (and GPU usage). Once I set to disable its all good, and framerate is regular (no dropped frames). Last edited by Harumi; 2nd October 2019 at 09:24. |

Compare with setting the calibration to BT.709 (since it is only 95% DCI-P3) but that might be oversaturated.

As huhn said it's bad to force disable deinterlacing. If a Blu-ray is interlaced it's usually for a good reason. You should create profiles in your madVR config, like this: Code:
if deintFps < 31 "LFR" else "HFR"

Btw I was not able to solve this and this (deinterlacing on/off its the same),I am not sure how this is called: |
