A:Answer This projector acts like a monitor or a TV without tuner, basically you can watch anything that is coming from any video source connected to it (considering the resolutions supported and Audio/Amplifier system for louder quality sound).
To watch TV programs, you need to connect your box to appropriate input; your box is what you receive your programs with such as Cable Box, Satellite Box, Digital TV Converter Box or any other Streamer that you use (e.g.: Roku, Amazon Fire, Android, Google TV, Apple TV, etc.)
Hope it helps.
