GoKawiilSamsung's Anynet+ HDMI-CEC feature: setup tips and common pitfalls
Samsung TVs use HDMI-CEC, branded Anynet+, to let connected devices like consoles and soundbars share control of power, input switching, and volume through a single remote. The convenience can backfire when devices send unexpected signals, causing TVs to switch inputs or power on unintentionally, issues that can often be fixed by checking cable connections, firmware, and CEC settings on both ends. Samsung's system supports up to 12 devices, but disabling CEC to solve one problem can break HDMI eARC audio functionality, since eARC depends on Anynet+ being active.
