Can't get HDR videos working

[MrMind 2]

My configuration:

Windows 10 Fall Creators Update (fresh install)
Geforce GTX760 with 388.00 drivers (fresh install)
HDMI High Speed Cable 0.8M
Samsung KS7000 (KS8000 in US), HDMI input set as Blu-ray player (if PC I can't change to "Movie" mode), UHD Color Enabled
Emby Theater 2.9.3 with MADVR 0.91.10 (included), Madvr video player enabled

 

I tried to play Life_of_ Pi_draft_Ultra-HD_HDR, Exodus_UHD_HDR_Exodus_draft and full length HDR movies. Nothing works.

 

In MADVR settings I have:    //C:\Users\Marcin\AppData\Roaming\Emby-Theater\COMObjects\madVR

properties: PC levels, 10 bit (or higher)
hdr: "passthrough HDR content to display" and "use Nvidia's private API"
rendering -> general settings -> enable automatic fullscreen exclusive mode -> ENABLED

 

In Nvidia Control panel
Refresh rate: 30Hz
Desktop color depth: Highest (32 bit)
Output color depth: 12 bpc
Output color format: YCbCr422
Output dynamic range: Limited

What should I change to play HDR movies?

Does your card support 12bit?

[MrMind 2]

I don't know but I guess Geforce 7-series is enough to play HDR content.

Is the file HEVC?

I assume you're not in US or UK.  If you are, have you tried using the native Samsung app as it should be a better option, it will play 4K HDR content.

 

Edit:  I think from the other topic you want TrueHD, that would be an issue then

Yes, its is.

That might be part of the problem. Check and see if your card supports HEVC. HEVC takes a lot of processing. If your card can't use HWA for HEVC, that could be causing some issues.

According to wikipedia GTX760 doesn't have HWA for HEVC

If that is the reason I need to buy new card

That combined with using MadVR requires quite a bit of juice. You could try lowering the settings and see if it makes a difference. There's still a chance something else is going on.
