When to apply Scheimpflug?
Only apply a Scheimpflug correction in case the overall focus of the projected image is not equally sharp (can
be caused if the projector is
NOT in parallel with the screen or a previous misaligned Scheimpflug) . Take into
account 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. Warping will be required to solve the distortion.
The disadvantage of Warping is a small decrease in pixel quality. 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. In case the SHIFT range is not sufficient then the
projector can be tilted and Scheimpflug can be applied.

distance and screen size).
