Subject:  TV switches source by itself

Samsung TV's have Anynet+ (also known as HDMI-CEC), a feature that allows connected external HDMI devices to inform your TV when they have turned on.

By default, the TV will immediately switch to this source when this happens.

The method to stop the TV from switching the source varies depending on the type of remote you have. Smart Remotes pair to your TV via Bluetooth, and IR remotes do not.

What type of remote do you have?
