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 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.
Note: For screen sizes not indicated on the chart,
use the formulas on page 1.
