    Issues with NUC7I3BNH using 4k and HDR

    Twerthi

      Greetings!  I am aware that there are multiple threads regarding both 4k or HDR, but none seem to address my specific circumstances.  I have a brand spanking new NUC7i3BNH connected to a Denon AVRX3400H receiver, which in turn is connected to a Vizio P65-C1 TV.  I have confirmed that both the TV and receiver are both 4k and HDR compatible.  I have updated to the latest BIOS for the Nuc and Windows 10 is fully up to date.  When resolution is set to 4k, the slider for HDR in Windows 10 will not work.  I flip it to On, screen goes blank for a few seconds, then it asks if I want to keep the settings, but HDR is Off again.  If I change the resolution to 1080P, HDR stays on.  That's issue 1.

       

      Issue 2 is when I leave resolution set to 4k and launch Power DVD.  Power DVD turns on HDR (while still at 4k), but the audio stops working.  If I switch inputs on the receiver and then switch back, audio is back, but the receiver seems to only receive a Dolby Digital signal no matter what audio is selected.  Once back in Windows, HDR goes back to being disabled, but audio works fine, which was confirmed by launching the Windows Dolby Access program and watching one of the videos to confirm the receiver sees a Dolby Atmos signal.

       

      Is this a bandwidth issue?  Is there something I'm doing wrong?  I'm using https://www.amazon.com/gp/product/B00SI1J98W/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 for cables, which I believe are capable of doing this?

       

      The only solution that I've seen that seems to work for everyone is to use a USB-C to HDMI converter, but from what I read it seems that it is used in conjunction with the built-in HDMI so it seems it's separating audio to one HDMI and video to the other, which won't work in my scenario.
