There is a function that has been hidden in the menus of your phone for years. TV and that, if you have not activated it, you are wasting time unnecessarily. HDMI-CEC — acronym of Shopper Electronics Regulate — is the standard that allows all your HDMI devices talk to each other and obey a single remote control. It’s been around since before Trim TVs were the norm, and today it’s more relevant than ever.
What is HDMI-CEC and how it works
HDMI-CEC is a technical specification integrated into the HDMI standard that allows bidirectional communication between devices connected by HDMI cable. In short, it is the protocol that makes it possible for your television and your soundbar, your console or your Chromecast to “understand each other” without you having to intervene with three different controls.
What many do not know is that this standard has existed since the early years of HDMI, but each manufacturer renamed it with its own name to differentiate itself. The result is that there are people with this function active without knowing it, and others who have never touched it because they do not recognize the name on the menu:
- Samsung It is called Anynet+
- LG called Simplink
- sony it calls it Bravia Sync
- Other manufacturers They simply call it “HDMI CEC” or “Regulate HDMI”
The function can manage up to 15 simultaneous devices connected by HDMI on the same television, assigning logical addresses to each one.
What is HDMI-CEC for in your living room?
The reason for HDMI-CEC is simple — eliminate friction between devices — but its applications go beyond just saving controls. We are facing a technology that completely reorganizes how you interact with your audiovisual equipment.
The most useful functions on a daily basis are:
- Synchronized power on and off — when you turn on your console or Fire TV, the TV turns on by itself and switches to the correct input
- Unified volume regulator — the TV remote can raise and lower the volume of your sound bar without the need for the bar remote
- Automatic font switching — if you start playing something on the Chromecast, the TV switches itself to that input
- Regulate cross play — you can use the TV remote to play, pause or advance on Blu-ray or streaming players
What this means is that in a typical living room setup — TV, soundbar, console and streaming stick — you can operate everything with a single remote setting, without complicated configurations.
When you should activate HDMI-CEC on your TV
The short answer is that you should have it enabled if you have more than one device connected via HDMI. But there are specific scenarios where HDMI-CEC makes a real difference and others where it can cause unexpected behavior.
Activate it if:
- You have a sound bar, soundbar or dwelling theater system connected by HDMI
- You use a Chromecast, Fire TV Stick, Roku, or Apple TV as your primary source
- You want everything to turn off by itself when you turn off the TV
- You share the TV with people who prefer not to deal with multiple controls
Consider turning it off if:
- Your devices turn on or change sources unexpectedly without you doing anything
- Do you have a console or PC that you want to remain on standby even if you turn on the TV?
- You use the TV in video display mode for work and you don’t want automatic interruptions
To activate it, the route varies by brand: in Sony it goes by Settings > External inputs > Bravia Syncon LG by Settings > Total > Simplinkand at Samsung for Settings > External device management > Anynet+.
Is HDMI-CEC activated by default on all televisions?
Not in all. Some modern televisions have it enabled from the factory, but many have it disabled in the input configuration menu. The recommendation is to check it directly in the TV settings according to the name your brand uses.
Does HDMI-CEC work with any HDMI cable?
Yes, the CEC feature travels over the same standard HDMI cable — you don’t need a special cable. What you do need is that both devices (the TV and the accessory) are compatible with CEC, something that most devices manufactured after 2010 already include.
Can I control the volume of my soundbar with the TV remote using HDMI-CEC?
Yes, as long as the soundbar is connected to the TV via HDMI ARC or eARC and both devices have CEC enabled. This is precisely one of the most valued functions of the technology – the system audio adjustment – and it works with most modern sound bars.
