The ADV751[13]W? datasheets document all the supported input formats. They're
split in categories, each of them having multiple variants called styles. The
styles are just numbered 1, 2 and 3 in the tables that describe the formats,
and there's a register field used to select a style. For some reason style 1
maps to register value 2, style 2 to register value 1, and style 3 to register
value 3. Go figure...
