Intel NUC 8th Gen: SMP’s HDR build: Atmos Skip fix?

  • Hi -

    I am running a NUC8i7BEH, TV does not pick up video coming as HDR, same build on a NUC11 works and tv switches to HDR mode. Is there anything to look for in the logs, I can see the following:

  • Fixed my issue, I have a TCL 55r615, had to change the hdmi input on the TV to use 2.0 (labeled as standard) :

    Setting the HDMI® mode (4K models only)
    On 4K (UHD) TVs, you can independently configure each HDMI® input to match the capabilities of the connected device. From the Home screen menu, navigate to Settings > TV inputs, and then select an enabled HDMI® input. Next, select HDMI mode
    and then select one of the following settings:
    • Auto – Let the TV determine the best setting. Use this option unless your HDMI®
    device does not correctly communicate its HDMI® version compatibility.
    • HDMI 1.4 – Configure the input for compatibility with HDMI® version 1.4, which supports a maximum refresh rate of 30 Hz at full UHD resolution. Most HDMI®
    devices will work correctly with the TV in this mode.
    • HDMI 2.0 – Configure the input for compatibility with HDMI® version 2.0, which supports a maximum refresh rate of 60 Hz at full UHD resolution. You must use this mode to view HDR content from the device connected to this HDMI® input. However, note that many older HDMI® devices do not work correctly when the TV’s HDMI® input is set to this mode.


    Thank you SMP for this build!
