Odroid N2 , latest LE and new Samsung TV. No HDMI signal

  • Due to changing countries I had my trusty N2 in storage for a year but finally with new TV I installed a fresh version of LE. However the TV is not picking up the box. Hoping someone can help out with resolving this.

    I know the N2 boots fine etc as I can connect it to my PC monitor via HDMI and everything is as expected. I've enabled debug logging then reconnected it to the TV and SSH'd in after booting. Here's the first few lines from the log with hardware/version info. Log links at bottom.

    TV is a 65" Samsung Q90

    Some things I've tried

    1. I've changed HDMI cables out including using the one that came with the Samsung Soundbar
    2. Whitelisted modes to just 1920x1080 as per https://wiki.libreelec.tv/configuration/…#mode-whitelist
    3. In CEC settings, fixed the HDMI port to 2 and ensured the the cable is plugged into port 2 on the TV

    I have an RPi4 laying about but need to pick up a proper HDMI cable for it so have that as a fall-back but this not working is bugging me and would love to get to the bottom of it.

    Thanks in advance.

    EDID data in Kodi.log shows 1080/3840 modes fine but this ^ looks like it's trying to set 4K GUI which won't work as the silicon only supports 1080p on the GUI plane. Have you fiddled with the GUI settings on the other monitor? .. because by default we set the GUI to 1080p. If no, I can't explain, but perhaps try clearing display settings (stop kodi, delete guisettings.xml, restart kodi) or force the initial DRM output to 1080p by appending "video=HDMI-A-1:1920x1080M@60" to kernel boot params in extlinux.conf.
