HDMI CEC Issues with Mixed Brands

[Gardenboy]

Can HDMI CEC cause issues when using devices from different brands, like an LG TV, a Yamaha receiver, and a Roku? What’s the best way to avoid glitches like unexpected power-ons, input switching, or lost control? Would turning off CEC on some devices help, or is there a better setup strategy?

Thanks in advance!

Hi! HDMI CEC can cause issues when mixing brands because each manufacturer uses it slightly differently. This can lead to problems like devices turning on by themselves, switching inputs, or losing control. The easiest fix is to turn off CEC on devices that do not need it, keeping it only where it is useful, for example between the TV and receiver. You can also use ARC or a universal remote to handle power and volume without relying on CEC for everything.
