16:9 - NEC GT5000 Installation Manual

16:9 Screens
The following diagrams show the relationship between projector position and the screen. Refer to the chart below for data.
Distances are in inches. For millimeters multiply by 25.4.
Ceiling Mounted Installation
Vertical Position for a 16:9 screen:
The Vertical Position adjustment moves
16:9 image up and down in the unused
portion of the 4:3 panel. 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. This adjustment is only available
when the projector is set for '16:9', '1.85:1'
or '2.35:1' in the 'Screen' menu.
Desktop Setup
Note: Lens shift is not available on
GT06RLB & GT10RLB rear lenses, which
should only be used for "zero degree/no-
offset" applications.
Note: Tilting the front of the projector up
or down by more than 45° from level
could reduce lamp life by up to 20%.
