Screen Shift in func-
tion of Screen Width
for various Lens
The vertical shift of the picture on the screen (Y-axis on diagram) is function of the screen
width (X-axis) and the shift of the lens in the projector. The shift of the displayed picture
can be calculated as follows:
Screen shift [mm/inch] = Lens shift [mm/inch] x 1+
Screen width
[m/inch]
LCD panel width

LCD panel width: 0.118 m (4,646")
To adjust the lensholder shift, handle as follow :
Features:
- Vertical shift of the lens possible between 20 mm (0.79") up and 6 mm (0.24") down
without removing the projector cover.
- Shift of the displayed picture on the screen up till 2 meters (6.5 ft.) over its standard
position.
- Makes it possible to project a geometric non-distorted picture from a non-standard
projection position.
- The shift of the lensholder is not determined by the lens used, but depends on the
screen width.
- Can be used with all available lenses.
- Can be used in dual or triple configuration in combination with BARCO's projection
frame or multifunctional flight case.
