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.
