Samsung TV switches sources by itself

Samsung TVs and the Odyssey Ark gaming screen have Anynet+ (also known as HDMI-CEC), which is 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 or gaming screen 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.
