Moving to this “dummy” channel will roll the aspect ratio through a 4:3 option, a full wide screen (some top clip) and a correct
aspect ratio 16:9. The code varies by channel (RGB or Video) and corresponds to codes in the manual, and is displayed with a
“Screen aspect ratio” and a code number. (No zoom ratios are provided, so as not to confuse users with too many options.)
The panel will remember the setting by channel. It might be convenient to use two channels (say S-Video and Component) from
