  • HDR on x86 Hardware

    Quote from chewitt

    I wouldn't be too surprised if Windows drivers look for properties frequently associated with HDR and fake/trigger the mode change on the TV and/or blindly force output in some way.

    I believe you are correct here. I have confirmed that the Kodi in windows reports there is no HDR capabilities on my screen. You were right about the AVR and it removing modes, if I plugged directly into the TV then I had many more 1080p modes. That does raise the question of how best to connect a pc to the AVR.

    I have since switched to a NUC6CAYH and it is shows HDR support in system info. I have tested a number of HDR videos and they are all playing in HDR, so that issue is solved at least.

    The curveball on modern PC boxes with DP hardware is whether an LSPCON chip is being used to generate HDMI, and if yes, what bugs the LSPCON firmware has, because they are notorious for issues - including the "but it worked in Windows" kind.

    Thank you, this may be what the issue is then. This is unfortunate as everything is much snappier in Libreelec. I will check configs again. I used a new drive to install LE so I can easily swap Windows back in. I hope this is not the case though.

    The onboard HDMI on this is v.1.4 so it can not possibly pass through HDR.

    TV switched to HDR mode? How it was connected to the TV?

    In Windows, the optiplex was connected to the receiver via a display port to HDMI adapter. On the TV you can see the detailed signal info, which shows that HDR was enabled for the HDR content.

    In LE, everything is connected the same way. If I look at the detailed signal info it lists SDR when playing HDR content.

    So I have a Dell Optiplex 3070 micro that I use solely for my TV. I am unable to get HDR videos playing in HDR. Kodi was previously able to play HDR content when the Optiplex was running Windows 10.

    My setup is the Optiplex connected to a Denon X1800H, which is then connected to a Sony Bravia 7 XR70C. The Optiplex is normally connected to the receiver via a DP to HDMI adapter, using 4k certified monoprice cables. I have been switching between the display port adapter and the on board HDMI but it is not making a difference. The Receiver is plugged into the TV via the HDMI 3 e-arc port.

    I tried two different files in the attached log, Stranger Things was one that I watched when in Windows and it was playing HDR then. Green Planet was added as another data point, though I did not watch that when in Windows.
