HDMI CEC- Why is it important?


HDMI CEC also known as Consumer Electronics Control, is an HDMI feature that allows a home theater or media room user to control all the devices connected via HDMI using one remote. With HDMI CEC you can command up to 15 devices including your display device, audio devices, Blu-ray player, TV box, gaming console, and so on using one remote.

Gone are the days when you would need a remote for each of your devices. Thanks to the HDMI CEC feature, which has been around for more than 13 years now, things have become much simplified and made flipping between devices that much easier.

However, you may be forced to use a specific remote for a certain device for some of the unique features but HDMI CEC is packed with the core features that you may need for your day to day use.

This feature was 1st introduced with HDMI 1.0 and updated with the release of HDMI 1.3. HDMI CEC has gotten better with the advancement of media technology in more and more devices.

How does HDMI CEC work?

HDMI CEC enables you to use one of your connected device’s remote to control your whole entertainment system.

For example, you can control your Blu-ray player using only the TV’s or projector’s (yes, some projectors are CEC compatible) remote. In this case, the remote communicates between the devices to send a signal through the HDMI cable to the Blu-ray player.

This happens because the CEC signal is a separate electrical signal to other Audio/Video signals that are sent through the HDMI cable. What this means is that you can also turn on or control a device in sleep mode or one that is turned off (HDMI circuitry is disabled) by using the CEC signal.

The CEC signal is identical to the AV signals but is of a higher-level and is more detailed. This signal is carried through a single wire and is sent with fixed timing and also has a special start signal.

But for the devices to work with this feature, they must be able to transmit the CEC signal.

Which features does HDMI CEC support?

HDMI CEC can support some of the core features found on most remote controls that you would need for your system from powering on your devices to the menu selection and even but not limited to the playback selections. With CEC you will no longer need a remote for every device for flipping between the various devices when using your universal remote.

The pros and cons of using HDMI CEC


  • Seamless integration and control of HDMI devices in your home theater system.
  • Can work in combination with HDMI ARC to reduce the number of cables that you need in your setup for a cleaner look.


  • Limits the ability of the HDMI ARC to deliver a full high-quality surround sound and limits you to a compressed 5.1 surround or uncompressed stereo audio set up.
  • Different manufacturers use different names to mean HDMI CEC which can be a bit confusing at first.


For some soundbars, you may need to turn HDMI ARC and CEC (check brand name online) to use this feature. However, in some cases, you may need to download an app to enable this feature and follow the instructions for that particular soundbar.

To use HDMI CEC on your Windows PC, your hardware including your graphics card and drivers must support the CEC feature. However, not many computers are capable of this. For some Windows computers that do not have the CEC feature support, you can use various products that can add support. These products can then be connected to your PC and display device via a USB-CEC adapter to send the CEC commands. However, you should keep in mind that not may Windows computers will support this feature.

If you are using a universal remote, HDMI CEC commands may sometimes conflict with the universal remote. To use your universal remote, you will need to turn off CEC from all your devices.

My final thoughts

Using HDMI CEC may not be perfect for smooth remote operation in your system as not all devices may have support for this feature. You can always use other universal remote-control options to streamline all the operations for all your components.

However, if most or all of the devices support HDMI CEC, you can always try it out and see how well it works for you.
