1 frame repeat every 41 seconds and it grows. This is what you meant ?
If not, where do I see or how do I calculate the interval ?

Not owning a C9/CX myself, I would assume you want to still use refresh rate switching at 120Hz. I'd use 2160p100, 2160p119, 2160p120. madVR should then switch to 100 for 25/50 fps content, 119 for 23/29/59 fps content, and 120 for 24/30 fps content. That should cover all bases.

Do you have any work around?
Mark, that's one of the ongoing issues. The workaround would be to have the player exit/close after each playback.

Yes, that is what I meant, thanks. That's bad, how much is it e. g. after 3 minutes of playback? And as VBB says, how much is it at 119Hz?

With a 3090 and a CX I don't have a 119 Hz option, nothing above 60 Hz besides 100 and 120 Hz, both in the PC section.

Smooth motion basically required for >60Hz.

Oh, wow. That's a big oversight on LG's part to not include that in the EDID. Shouldn't come as a surprise, I guess, when all people care about these days is gaming

MPC-HC version 1.9.8
madVR version v0.92.17

madVR is set to "passthrough HDR to display" with "send HDR metadata to display" checked

Monitor: Lenovo Legion Y27q-20
GPU: RTX 2070 Super
Connected via display port

Windows "Use HDR" and "Stream HDR Video" settings are both on.

When I try to play a HDR video with MPC-HC + madVR, the colors are extremely dark. Watching HDR videos in YouTube on Chrome works fine. Is this a driver related issue or did I configure something wrong?

I've something in the release notes like "admin rights now required for EDID override", maybe this is related, they changed something in the driver maybe? I've never used CRU so it's just an idea.

So:

- Enabling CUVID deinterlacing in LAV produces no artifacts at all, this is the best mode but unfortunately this means I can't control deint anymore with madVR hotkeys and have to open LAV settings to switch between film/video which is a pain.
So it looks like the artifacts come from something in madVR, as they don't show up using other renderers or with CUVID deint. Maybe madshi isn't using the correct DXVA deint mode. I will try to do more tests with DXVA Checker.
In both scenarios, the deinterlacing quality itself (apart from the artifacts) isn't any better than with DXVA (no 'HQ processing' anymore in current LAV).
I've also tested the other software deint options in LAV, YADIF is horrible and has even more artifacts than madVR DXVA, probably because it's not motion adaptive. Weston is really good, I'd say better quality than NVIDIA hw deint but still not as good as AMD's. Unfortunately uses a lot of CPU on my old system, and same inconvenience as CUVID which is not controllable from madVR.
I hope when madshi implements his planned motion adaptive deint for the Envy, that he asks us to test it.
I could also re-encode all my SD interlaced stuff to 50p on my desktop using AMD's deinterlacing, SDTV won't last eternally, but it takes time I'd rather use for something else.

madshi is aware of issues with DXVA deint he simply doesn't know why they exist:
http://bugs.madshi.net/view.php?id=652

maybe forcing YV12 instead of NV12 helps or so.
but i'm not even close to what you call artifacts...

Thanks, I saw that but I'm an admin so shouldn't be the reason.

I'll do more tests when my rig is up.

Turn those off and let madVR do the switching. Let us know if that fixes it.

I'm still getting really dark colors. Windows HDR is off and hdr in madVR has been set to "let madVR decide".
Here are my NVIDIA control panel settings & madVR info (Ctr+J)


HDR playback using my laptop connected to my monitor does work, so I'm 100% sure this is a software/driver issue...

Something interesting I noticed:
When I press ALT+Enter to make MPC-HC fullscreen, there is a brief "hang"/lag before it actually enters fullscreen. During this brief delay, I can see the actual HDR colors/brightness, but once entering fullscreen it goes back to being super dark.

One thing I would change still is to set madVR to 10-bit. Your monitor seems to handle that well, so you might as well use it throughout the video chain. Also, you should enable smooth motion in madVR, since you're outputting at 165Hz. This will remove any judder.

As for why HDR is not working properly, that's a tough one. Are you on Windows 10, and if so, which version? Judging by your screenshot, LAV is set to "none" for the decoder. You could try switching that to D3D11 native (automatic) to see if that makes a difference.

Lastly, what's your Nvidia driver version? Try the latest, if you haven't already, to see if that makes a difference.

Speaking of drivers I forgot to post that the latest Nvidia driver has proper metadata. Basically no change from the previous driver in any behavior.

Windows 10 Pro 19042

It was originally set to D3D11. Changing to DXVA2 (copy-back) or DXVA2 (native) don't fix anything.

My laptop is running a much older version of NVIDIA drivers...

One more thing I noticed: When I play the HDR file with MPC-HC, it's not just MPC-HC that ends up with darker colors - my entire monitor seems to go into some darker display mode...

I just leave it on Video and it seems to always switch correctly itself. i.e. if I play film it does not deinterlace but if DTV it switches on automatically (I assume decided within nvidia hw).

I find CUVID with MadVR also to have the least artifacts.

Even C9 version has this modes in EDID. Why do you think that CX does not have?

Are you saying the C9 has 119 as an option? That's great then, and even more of a head-scratcher as to why the CX doesn't.
