Image Adjustments - Webster IRP 4100 Installation Manual

Image Adjustments

When properly adjusted, the projected image should just fill the
entire screen. The edges of the image should be straight and parallel
to the edges of the screen. The distance between the edges of the
screen and the edges of the image should be no more than 0.2"
(5mm) on all sides.
To adjust the image:
1 Display an image that has very clear boundaries on all four
sides. Some users may find it easier to use their computer's
Desktop screen, while others may wish to run an application
that enables them to display a full-screen, all white image (such
as a paint program, or the Webster application window with the
Current Board selected and shown in full-screen view).
2 If the image on your screen is too large or too small, adjust the
projector zoom until the image nearly fills the IRP screen without
extending beyond its edges in any direction.
Refer to the documentation that came with your projector for
specific instructions on how to find and adjust the projector
zoom control.
3 If the image on your screen is not in focus, adjust the projector
focus until the image is clear and sharp.
Refer to the documentation that came with your projector for
specific instructions on how to find and adjust the projector
focus control.
4 If the image on your screen is not square with the screen, place
the alignment pattern decals in the corners of the IRP screen,
as follows:
a Locate the alignment pattern decals in the toolkit taped to
the inside of the IRP accessory compartment (left-rear of the
console). The decals will appear to be a single large pattern
printed in black on transparent plastic and mounted on a
paper backing.
