HDMI became the industry standard for transferring uncompressed video data to a variety of devices after VGA and DVI interface connectors. Right now, the HDMI interface can be found on just about anything, including laptops, projectors, TVs, gaming consoles, and more. If you’re not aware, the maximum bitrate that HDMI allows is 48 Gbit/s, which accounts for its popularity. Additionally, it adds capabilities like HDMI-CEC, also known as HDMI-Consumer Electronics Control, which is designed to promote device interoperability when connected to an HDMI port. What exactly is HDMI-CEC and how may consumers benefit from it? Now, read our explainer below to acquire more in-depth information about HDMI-CEC.
Everything About HDMI-CEC You Need to Know (2021)
The sections about HDMI-CEC that we addressed in this post are listed here. You can find all the details about HDMI-CEC, including its operational mechanism and device compatibility. Click on the link below to access the site with ease.
What is HDMI-CEC?
Let me offer you a straightforward example to illustrate HDMI-CEC before I go too complex. Multiple HDMI connections are now available on TVs, both smart and non-smart, to connect a variety of equipment, including set-top boxes, game consoles, media players, home theatre systems, and more. Additionally, each of these devices has a unique remote control that can be used to access menus, change settings, and turn the system on and off.
It basically implies that you have many remote controls for various TV-connected gadgets, which adds to the clutter and slows down the experience. What if you want to transition from viewing a movie to playing a game? To play games on your console, turn it on using the specific gaming controller after turning off your set-top box so that no HDMI input is enabled.
Similar to this, what happens if you wish to stream content while playing games using a Chromecast that is linked to your TV via an HDMI port? To close the active HDMI input, you must power off your console. After that, you can stream video from your smartphone.
Because to HDMI-CEC, you can use the present HDMI input on new TVs without turning off the set-top box or game console. With a simple flick of the TV remote, you may quickly switch to any device by changing the HDMI input. Because of HDMI-CEC, devices may now communicate with one another and carry out several tasks that previously required manual intervention.
What HDMI-CEC is all about is communication between devices linked via the HDMI connector. The HDMI consortium sought to introduce a solution that would enable HDMI-connected devices to communicate with one another and respond to commands from a single source without the need for individual remote controls. Because of this, you may use the TV remote to operate any connected devices, including set-top boxes, game consoles, and media players, on HDMI-CEC capable devices.
For instance, with HDMI-CEC compliant devices, you may just click the power button on the TV remote to switch on both your TV and set-top box. The step-top box doesn’t need to be turned on independently. Similar to this, you can use Chromecast to broadcast any material on your TV by disabling the existing HDMI input, which previously required manual intervention. All of these benefits result from the HDMI-CEC capability, which is present on many TVs.
HDMI-CEC requires hardware implementation in addition to just being a software feature. The good news is that CEC was introduced by the HDMI Consortium in 2006 and became obligatory for HDMI port hardware implementation (wiring) at that time. Unfortunately, not many TV makers adopted this capability until as recently as 2015. The software implementation, however, was left up to the discretion of TV manufacturers.

You may argue that while every TV has the necessary hardware to support the HDMI-CEC capability, it is not currently software-enabled. In 2017, even Google included assistance for HDMI-CEC on Android TV. It’s crucial to remember that TVs that come pre-installed with Android TV OS (such as the Mi TV in India) typically lack support for complex HDMI-CEC instructions.
One Touch Play, which turns on several devices at once and lets you use one remote to control all peripherals, is not supported while switching between different HDMI inputs. However, the Mi TV Stick, introduced in 2020, supports HDMI-CEC. The same is true for Sony’s Android TVs and Nvidia’s Shield TV.

Frequently Asked Questions
Q. What Does HDMI CEC Do?
Multiple HDMI ports may communicate with one another more easily thanks to HDMI CEC, which also allows commands to spread to other devices. With simply the TV remote, you may essentially carry out privileged operations on another device.
Q. How Do I Use HDMI CEC?
While the basic commands for HDMI CEC are enabled by default, you must enable HDMI CEC on your TV’s Settings page in order to access the advanced commands, including audio passthrough and one-touch recording. From the list we provided above, choose the trade name for HDMI CEC that corresponds to your TV, and then search for it on the settings page.
Q. Is HDMI CEC the Same as HDMI ARC?
HDMI ARC solely deals with audio passthrough, while HDMI CEC may carry out a variety of tasks like power on/off instructions, video/audio passthrough, and more.
Q. Does HDMI CEC Cause Input Lag?
Contrary to popular belief, HDMI CEC has a distinct channel for the transmission of electrical impulses, hence it does not result in input lag while gaming.
Q. Do All TVs Have HDMI CEC?
On the hardware aspect, you can state that TVs introduced within the last ten years support HDMI CEC (assuming it has an HDMI port). However, not all TVs have HDMI CEC functionality because TV manufacturers for many years did not implement HDMI CEC on the software side.
Q. Does Non-smart TVs Support HDMI CEC?
Yes, non-smart TVs can absolutely support HDMI-CEC since TVs with HDMI ports are required to have CEC-compliant hardware. To make your TV completely HDMI CEC compatible, you can connect an Android TV Box, a Fire TV, a Roku Stick, a Mi TV Stick, or another device.
