Composite (Video) Output:
For connecting to an older TV or portable DVD player, or that old Commodore 64 monitor in your closet.  Not much use for anything other than playing arcade games. Very difficult to read text especially on smaller screens. If you have trouble with edges chopped off then try some of the overscan options in the configuration utility. (sudo raspi-config)
