Configure HDMI settings on your TV

How to enable HDMI-CEC and ARC on your TV

HDMI® is well known for its ability to deliver audio and video over a single connection from devices like Blu-ray™ players, game consoles, and Roku® streaming players. HDMI also includes a couple lesser-known features called HDMI-CEC and ARC that use two-way communication over the same connection to simplify how you use and set up your entertainment system. However, before you can take advantage of these benefits it is important you check the settings on your TV and make sure the features are enabled. It is not uncommon for them to be disabled by default.

This article provides more details about HDMI-CEC and ARC, and outlines steps to enable the features for several common TV brands.

What is HDMI-CEC?

CEC, or Consumer Electronics Control, allows commands to be shared between devices over the same HDMI connection as audio and video, letting you control common functions of different devices without having to juggle remotes. For example, with CEC enabled you can use your TV remote to adjust the volume of a connected audio device such as a Roku Streambar®, Roku Streambar Pro, or Roku Smart Soundbar. Or, with your Roku remote you can easily turn your TV on and off without needing to pick up another remote.

  • Note: CEC does not allow control of all aspects of every device. For some functions, you may still need to use the original remote for a device.

What is ARC?

ARC, or Audio Return Channel, lets your TV send audio to an external audio device such as a Roku Streambar, Roku Streambar Pro, or Roku Smart Soundbar without the need for additional cables. This allows audio from your TV's tuner and devices connected to your TV such as a Blu-ray player, game console, cable/satellite set-top box to be enjoyed on an audio device other than your TV's built-in speakers. To use this feature, the audio device must be connected to the "HDMI ARC" or "ARC" port, which is common on smart TVs manufactured in 2009 or later.

  • Note: Consult the user manual or online documentation for your TV if you are not sure your TV has an ARC port.

How to enable CEC and ARC

Enabling CEC and ARC is different for every TV brand. Some have separate settings for each, while others combine the features into one setting that turns ARC and CEC on or off at the same time. When looking through your TV's menus for these features, understand that manufacturers may not refer to them by name, but rather as part of a branded trade name. In general, you can often look in a "settings" menu for CEC-related settings, sometimes in a "system" or "advanced" submenu. ARC-related settings may be located in the same place, or they may appear separately in an "audio" or "sound" menu.

Each brand in the list below includes the trade name(s) in parenthesis that the manufacturer typically uses when referring to the features in their TV menus. You can refer to the sample instructions that accompany some of the TV brands, but the steps may vary from model to model, and may change when TV software is updated. When in doubt, refer to the user manual or online documentation for your specific make and model.
