WMC 7 and HDR10 movies/videos

#1

Hey all,

I searched around but, didn't find anything. I have not run into this before so I figured someone else must of. I finally got a new TV, and it supports all the good features, HDR, Dolby Vision etc. YEA ! My Xbox one X looks epic on it.

So I ripped a 4K blu-ray with HDR to my built in movie library. I play the movie, No HDR logo (showing that it switched to HDR), and the movie looks almost black and white. A sign I have seen by playing HDR content on a Non-HDR TV.

The Video card is a GTX1050ti, and I have confirmed the video card does support it, I am running HDMI with a good cable and the AVR supports HDMI 2.0b, so it's nothing in my path that would break it.

Is this a Windows 10 only thing (As I search for HDR and Windows 7, all I get is Windows 10 things)? Or is there a way to enable it on 7, or even 8.1 (time to move to 8.1 ?)?

Hey,
I'm pretty sure that HDR suport native to windows was only introduced with 10. And even then, it's not very good. In my experience HDR just makes text blurry, lighter and unreadable at high res with low scaling (I like everything small) so i never have it enabled.
If you're looking to play the files back through WMC then it doesn't work anyway. I can switch the Windows Desktop HDR mode on and my TV will display that mode, as soon as i launch WMC it goes back to normal mode. I guess that programs and apps have to support it and, as expected, WMC doesn't.

Hope this info helps :)

You would have to use an external player for those file types. Newer versions of LAV will pass HDR Metadata to the renderer but WMC's renderer can't be changed, and wont display HDR I believe.

Thanks. Windows 10 changed playready for HDR and DRM, it's what broke cablecards in WMC. According to NVIDIA, it does work under Windows 7, just any DRM'd sources that USE Playready 3.0 will not work under Windows 7.

I am not worried as much about WMC here, it's the Media player, I believe it still uses Media Player. When I movie/video starts with HDR, WMC is not really active.

This is how I understand it from the Beta test days on Windows 7 WMC... and I was talking to one of the members on the eHome team about this. It's why if you install Windows 7 clean, DIVX files will not play at all in WMC...and will not play in Media Player but, once you install a codec...the plays in both..

So it "SHOULD" work...

I use LAV codecs with Shark007.... Interesting, I have not updated it in a while, maybe it's time to TRY it. Just to TRY...

As I still use the built in Movie Library, I didn't want to change now. I know when I had 3-D movies, it treated it fine and the TV switched to 3-D mode (my last TV supported 3-D, this one does not). I don't want a different library for different types of movies.

Am I screwed because I want every movie in one library ?

Best to stay OUT of WMC for anything above 1080p SDR...I use VLC and Media Center Classic for most non recorded TV stuff...you can add MadVR to your Windows 7 system which has a toggle for HDR10 metadata trigger, so your TV will auto switch to HDR10 on it's own and you can throw HDR files from those non WMC players, assuming you get one that is HDR compatible.

If you think HDR on Windows 10 is fuzzy, it's not, it is that you are using HDR mode for the desktop, which is not what HDR is made for. To get 10 bit color, over HDMI 2.0, you can't use RGB, so you end up loosing all the stuff that makes text look sharp, but not loosing anything for moving video.
