Vertical Position for a 16:9 screen: The Vertical Position adjustment moves the 16:9 image
up and down in the unused portion of the 4:3 DLP panel. This adjustment is only available when
the projector is set for 16:9 in the "Screen" menu. The range of Vertical Position is dependent
on aspect ratio and 3D Reform used. If 3D Reform is not used, the approximate range of
vertical position is +/-0.167H (H=Screen Height) when using a 16:9 screen. (See "Screen Type"
and "Position" in user manual)
