When to apply Scheimpflug?
Scheimpflug correction procedures may only be carried out by suitably trained and experienced
technicians.
A Scheimpflug correction should only be applied when the overall focus of the projected image is not equally
sharp (for example, if the projector is
NOT in parallel
with the screen or as a result of a previously misaligned
Scheimpflug). Be aware that the consequence of applying Scheimpflug correction upon a screen not in
parallel with the projector is that the projected image differs from the rectangle shaped image. In other words
“
distortion
”
of the projected image occurs.
Masking
will be required to solve the distortion.
The disadvantage of Masking is loss of content. Therefore it is
strongly recommended
to place the projector
in parallel
with the projection screen and use the
SHIFT
functionality of the Lens Holder to match the
projected image with the projection screen. If the SHIFT range is not sufficient then the projector can be tilted
and Scheimpflug can be applied.

Required tools
•
Allen key, hex size 4
•
Allen key, hex size 5
Preparation
1.
Prepare the test area. Barco recommends a projector-screen distance of 2 metres be used for all Scheimpflug
adjustments.
Verify that the throw ratio of the installed lens matches the requirements of the installation area (projection
distance and screen size).
2.
Check that the lens is correctly installed, and lens shift is in centre position.
3.
Open the focus ring all the way up.
4.
Go to Main Menu / Test Patterns / Full Screen and select to display the Focus test pattern.
5.
Zoom the lens to its widest opening (maximum image size on the screen).
6.
Remove the plastic lid to have access to the 3 adjustment screws.
