What is CEC and how does it work?
CEC (Consumer Electronics Control) is a feature that allows devices connected through HDMI to control each other. It enables a single remote control to operate multiple devices, providing a seamless and convenient user experience. CEC is a standard protocol developed by the HDMI consortium, and it’s designed to simplify the process of controlling multiple devices connected to a TV or other display devices.
For example, when you turn on your TV, CEC can automatically turn on your soundbar or Blu-ray player, and even switch the input to the correct source. This eliminates the need for multiple remotes and makes it easier to use your devices. CEC is supported by most modern devices, including TVs, soundbars, Blu-ray players, and game consoles. However, not all HDMI cables support CEC, which can limit its functionality.
Do all HDMI cables support CEC?
No, not all HDMI cables support CEC. While CEC is a standard feature in most modern devices, not all HDMI cables are created equal. Some HDMI cables may not support CEC, or may only support it partially. This can be due to various reasons, such as the cable’s design, materials, or manufacturing process. It’s essential to check the specifications of the HDMI cable to ensure it supports CEC if you want to take advantage of this feature.
It’s worth noting that even if an HDMI cable supports CEC, it may not work as expected if the devices connected to it don’t support CEC or have different CEC versions. Therefore, it’s crucial to check the CEC compatibility of both the HDMI cable and the devices you’re connecting.
