This guide will provide some troubleshooting steps that may resolve this issue.

1 Introduction

Consumer Electronics Control (CEC) is a feature of the HDMI standard that allows your HDMI-connected devices to work better together. By exchanging information such as the current volume, which device is providing audio and video, and which remote-control buttons are pressed, devices can often be controlled over HDMI with a single remote control.

CEC is known by several manufacturer-specific trade names. Below is a list of common trade names used for HDMI-CEC:

  • AOC: E-link
  • Hitachi: HDMI-CEC
  • LG: SimpLink
  • Mitsubishi: NetCommand for HDMI or Realink for HDMI
  • Onkyo: RIHD (Remote Interactive over HDMI)
  • Panasonic: HDAVI Control, EZ-Sync or VIERA Link
  • Philips: EasyLink
  • Pioneer: Kuro Link
  • Runco International: RuncoLink
  • Samsung: Anynet+
  • Sharp: Aquos Link
  • Sony: BRAVIA Link or BRAVIA Sync
  • Toshiba: CE-Link or Regza Link
  • Vizio: CEC
