USING THE PROJECTOR
Rev I February 2015
Edge Blend procedure
1. Align the projectors as they will be used in the array.
Each projector should be perpendicular to the screen, or as close as possible. Ideally, each projector should allow for a minimum of 20%
screen overlap where it is adjoined by other projectors. Overlaps should be the same in size across the array.
How to align the projectors:
•
Ideally, all alignment should be achieved by physically moving the projectors and by using the
Lens Shift
and
Zoom
functions.
•
If necessary, use
Image > V Position
and
H Position
.
•
Do not use geometry corrections.
Example: 1080p projector overlapped on all
sides
1
Overlap to the left
This overlap takes 20% of the image width, or 384
pixels.
2
Overlap to the top
This overlap takes 20% of the image height, or
216 pixels.
3
Area without overlaps
This area is also called
unblended region
.
