Both formats use the full 0 - 255 space: however, 0 and 255 are supposed to be reserved (although they are encodable).
In the digital PC format, 1 is black and 254 is white. There is no provision for displaying Below Black and Peak White signals. There are artifacts produced from changing to or from the digital video format to or from the digital PC format.
In the digital video format, 16 is black and 235 is white. Values 1 - 15 are called Below Black and are used to compensate for black dipping below the reference level (16). Values 236 - 254 are called Peak White and are used to compensate for white peaking above the reference level (235).
You should always choose digital video levels, unless your display forces you to send it digital PC levels.
The most efficient path is seldom a straight line.
