What is fullscreen?
This is the typical ‘square’ image favoured (until recently) by television presentations. This aspect ratio is expressed as 4:3 or 1.33:1, which means that the frame is 1.33 times as wide as it is tall. Fullscreen presentations fill the entire screen of standard ‘square’ televisions. If a fullscreen image is viewed on a widescreen television, the screen will be wider than image and black bars will be visible on the right and left sides.
