I still don't get why doesn't Linux Foundation and someone else come together to fork AOSP to strip out Google stuff and make it a real Linux distro.

    The TV will be connected with HDMI and computer will have its DisplayPort converted to HDMI by a supported adapter. But:

    most adapters do not support the CEC Tunneling feature, and of those that do many did not actually connect the CEC pin. Unfortunately, this means that while a CEC device is created, it is actually all alone in the world and will never be able to see other CEC devices.

    TL;DR

    Connect your computer's DisplayPort with DP-HDMI adapter to TV's HDMI. To test if the adapter tunnels CEC, run in a terminal:

    cec-ctl --playback && cec-ctl -S
    

    Which should show at least two devices.

    It is rare that a computer have HDMI-CEC natively.
    Try the command "cec-ctl" (which is part of v4l-utils) or take a look at the Arch Wiki.

    Even if your hardware doesn't support it, you can still use displayport with an adapter or even a usb+hdmi adapter.
