COMMON PROBLEMS HDMI-CEC

The HDMI-CEC protocol does not have a single implementation, this means that each brand in addition to calling it what it wants can have different control messages that make our device does not understand certain actions. We recommend below some points to keep in mind to adjust the systems well.

  • Normally we can only control, change volume, channel, cursors, OK and on/off.
  • The shutdown system has different options, you have to try different combinations in the HDMI-CEC menu.
  • The volume up or down speed can be adjusted on some TV-Boxes and AV receivers, see manual.
  • Sometimes HDMI-ARC will not work if we do not have HDMI-CEC enabled.
  • Change HDMI cable, we recommend one type HDMI 2.0 Ethernet.
