In old cathode ray tubes (CRT) An electron beam hits a phosphor coating, on the inside of the tube, causing it to glow. Electronic control of the beam, by altering position and strength of it, will make up a picture when scanned across the tube rapidly. The slow fading of the phosphor, (when the beam has gone), and the persistence of vision of our eyes, makes it look like a picture rather than a moving dot of light.
Modern LCD Tv's, open and close little shutters held in a liquid crystal. They are switched in sequence (the same pattern as a CRT above).
The shutters let light through from behind. The light is provided by small fluorescent tubes or white LEDs.

The TV format setting is so that it sends the correct picture information when connected to a TV. It may be connected to a 4:3 aspect ratio TV or a 16:9 aspect ratio TV. For example if it was sending a 16:9 picture to a 4:3 TV, some of the picture to the left ad right sides would be missing. If sending 4:3 picture to a 16:9 TV the picture would be stretched across the screen distorting the picture.
Picture is AM, sound is AM or FM
