Latest version work really good. No problems realized while in productive use.

New drivers for Win 10 Creators Update and NVIDIA and AMD are out for HDR. If someone get manage HDR to work please write me / here. It should be now possible with the latest update to activate HDR-Mode on TV for all applications. In NVIDIA-Panel this option can be set directly (i read that only, can't test). In AMD panel i didn't found anything.

madshi wrote in doom9 forum, that the integration in madvr could take some time. So would be nice to get a ability to activate it manually and maybe a possibilty for a key-shortcut.

In Amd drivers HDR is activated automatically in TV when I set output pixel to ycbcr 4:4:4, if i set rgb 4:4:4 tv turns back to normal mode.

EDIT: I was wrong, it depends on the freq rate, rgb support hdr just for low rates. the HDR switch ON/OFF is under "change display setting" in win10.

Hi @Sebastiii
i'm not sure, if it is a bug or related to wrong setting of MadVR. With some files (1080/59) i get heavy stuttering an a lot of dropped frames. Playback with EVR is working fine. Logs and some infos are attached ->

Hi @Helios61, just a suggestion from me.

can you try set upscaling to bilinear or dxva2 (proccesing properties in Madvr) and check again ?

Next tests will follow on weekend...Real life

Might be a little bit OT but i have updated to WIn10 creators update and the newest Nvidia drivers recently in order to check out HDR capabilities.
Problem is windows turns on HDR for every content and not only for HDR Demo clips for example and the driver seems to be buggy as well at the moment so i switched back to an older version of the Nvidia driver again as at least gaming in HDR is possible that way.

I think in order to get that right MadVR Metadata pass-through has to be implemented first. Unfortunately i guess this will take a while....

(I cant switch to real HDR mode on my LG E6 manually so its needs to be done automatically)

Anyone feel like making a guide how to setup profiles etc? I would like to try MadVR, but only for smaller quality than 720p, since my TV is 1080i/720p only.

There is an excellent guide here : HOW TO - Set up madVR for Kodi DSPlayer & External Players.

Problem:

1. MadVR displays fullscreen video in a window with a title bar and border.
2. Need to alt+tab after starting video to watch the video.

Been using madvr with mpc-hc as external player for sometime. Thought i'd try the new internal madvr renderer. I get a black screen. Video starts but I have to alt+tab to get to it. The video fullscreen size but is windowed, see attached I'm guessing the problem is one of the renderering settings is not compatible with MP. BTW I use Win10 and I don't use any refreshrate change. Running the standard version of MP 1.6 Final with no modifications, recently upgraded from 1.5 Final version.

You can see in the 2nd video that MP is running 2x windows,






This is me pressing alt+enter to show it's not an alt+enter fullscreen issue.

Hey guys,

just found an exciting update for MadVR in case someone is interested (copied the message from doom):

madVR v0.91.9 released

http://madshi.net/madVR.zip

Code:
* added support for sending HDR metadata via Nvidia's private API
* added support for sending HDR metadata via win10 (not tested yet)
* fixed: processing (not converting) HDR was not handling gamut correctly
This is just a quick release with HDR metadata support. Nothing else has changed. For Nvidia users I recommend using the private Nvidia API to send the metadata. This API has several advantages:

1) It works in all OSs starting with Windows 7 (I think).
2) It works with both D3D9 and D3D11.
3) It's true "passthrough", the GPU driver doesn't modify the HDR pixels.

BUT: It only works for Nvidia GPUs and requires a fairly recent GPU driver version.

AMD/Intel users will have to use the new Windows 10 HDR APIs. I've implemented support for these, too, but couldn't fully test them yet, so they may work, or maybe not. Let me know. These APIs will probably behave differently compared to the Nvidia API. I'm not sure if they're true "passthrough". If they are, then probably only in fullscreen mode. These Windows 10 HDR APIs require the Creator's Update to be installed, and you need to activate "use D3D11 for presentation".
