That is the player's responsibility, madVR will render to whatever size the player asks for.

Zoom Player is very good at that kind of thing.

So I can set a lens memory on my JVC when a video starts to play.

But how can I set a lens memory when a video stops playing?

I want to revert back to my main default lens memory when playback stops and only be in my special video lens memory when I’m playing any video in madvr.

Sorry guys, terribly busy atm. Just to let you know: My Nvidia driver contact just informed me that the HDR passthrough problems (not always engaging, and incorrect metadata) should be fixed in the next bigger driver release.

FWIW, I also noticed this line in the information for the latest cumulative update for Windows 10: "Addresses an issue that prevents users from configuring their screens for high-dynamic-range (HDR) video playback."

What exactly that fixed or if it'll affect madVR in any way I don't know.

should be unrelated because that's about the windows API.

I bet it's gonna be fixed for 1 or 2 drivers and then they'll break it again.

Maybe, but, at least the 20xx guys and gals will have a useful driver they can roll back to. And the rest of us will have a later driver we can use.

Good to hear because at least based on my testing most my issues revolved around 4K HDR content or display output. Whether it be windows or the content.

Some calming down on the madshi quoting would be nice, that's five times over six posts. Do you really need him to be notified of your reply? Do we need to a full quote to understand you're replying to madshi?
A simple "thanks madshi" works fine to show you're replying to a post of his.

Honestly, it looks a lot worse on mobile, but can ya make an effort to not spam quote madshi's posts? Especially when he does release posts as it's much much larger, cheers.

I managed to make a video of a direct comparison between the working D3D11 windowed 8 bit mode with my AMD card and the "overblown reds bug " in D3D11 fullscreen windowed 10bit mode. Any suggestion where I should upload the video that you guys can watch it?

Hi everyone,

I own an RTX 2070 and as most of you have been suffering with stuttering in HDR at 24 FPS. Ultimately I’ve discovered that turning on windows 10 HDR in advance and letting Madvr run with "OS HDR" clears up the stuttering. Other than having to toggle it manually (especially as it is incompatible with 3D content when left enabled) is there a qualitative downside versus the Nvidia mode?

Cheers!

Yes, Windows does its own HDR tone mapping that nothing can control and does not take metadata into account. I am not sure how this interacts with madVR's tone mapping, if you are using madVR to process the HDR.

I use 60 Hz smooth motion instead of stuttering 24 Hz. It really is a good option in my opinion.

Thanks - very interesting. Is there a way to empirically test this? If I play an HDR MKV through the Windows Movies and TV app with OS HDR on, through JRiver/MadVR with OS HDR on and metadata pass through enabled, and through JRiver/MadVR with NV HDR and pass through on, the results aren’t distinguishable to me aside from the stuttering.

Well there was a post a little while ago that showed nVidia drivers after 398.11 were also not passing metadata properly.
https://forum.doom9.org/showpost.php...ostcount=54686

The thread below is a list of drivers and issues that people have reported.

https://forum.doom9.org/showthread.php?t=176013

So it may be a case of if you are using a later nVidia driver that may be the case and both Windows and nVidia are doing the same thing.

I use 385.28 as it seems to have the best feedback for most things working, but I also never knew the difference between working metadata or not, I only found this out due to this thread.

Hey, on your oled, how do you find Smooth Motion vs 23p with Real Cinema?
