In the 51/05, the setting is described on page 41 of the user manual.
Auto The video signal that is output (YCbCr or RGB) is switched automatically.
YCbCr 4:4:4 Select this to output the video signals as YCbCr 4:4:4 signals.
YCbCr 4:2:2 Select this to output the video signals as YCbCr 4:2:2 signals.
RGB (16 to 235) Select this to output the video signals as RGB signals. Choose this if the colors seem too dense and all the dark colors are displayed in a uniform black when RGB (0 – 255) is selected.
RGB (0 to 255) Select this to output the video signals as RGB signals. Choose this if the colors seem too faint and the black seems too bright when RGB (16 – 235) is selected.
Normally it is recommended to set this to Auto. When set to Auto, the optimum video signals for your TV are output.
Hope this helps.
Happy Holidays to all!
