HDMI-CEC (HDMI Consumer Electronics Control), or "CEC," is a TV feature that makes your devices work better together, but is often disabled by default.
Enabling HDMI-CEC will allow you to take advantage of additional Highfive features, such as automatically turning on your TV, and switching to the Highfive input when you want to share your screen. Additionally, this standard allows devices to 'name' your ports. When cycling through inputs, instead of 'HDMI 1' you'll see 'Highfive.'
Many TV manufacturers call HDMI-CEC by a branded trade name. The following is a list of popular TV brands and the name of the setting you'll want to turn on in your TV settings menu to enable CEC:
- AOC: E-link
- Hitachi: HDMI-CEC
- LG: SimpLink (will not work with Highfive on all models)
- Mitsubishi: NetCommand 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 Sync
- Toshiba: CE-Link or Regza Link
- Vizio: CEC
Generally, this feature is turned off by default. You can find these settings in your TVs menu. If you need additional help, try your TV's manual, or consult the manufacturer.
After enabling HDMI-CEC, you'll be able to open your Highfive app (desktop or mobile), choose screenshare or video call with your room's device name, and your TV will automatically turn on and change to the correct input.
