Does enabling HDMI-CEC affect the TV's performance or picture quality?
Enabling HDMI-CEC does not impact your TV’s performance or picture quality. It is a communication protocol designed to improve usability by streamlining device management. Your TV’s resolution, colour accuracy, and overall performance remain unaffected while enjoying the convenience of HDMI-CEC functionality.

How do I disable HDMI-CEC on my TV if needed?
