Edge Blending Procedure
NOTES: Before attempting to work with edge blending software functions, you must
1) physically align the projectors/images by correctly overlapping the displays from
your intended external source, and 2) Match colors and Brightness Uniformity.
For a shared edge, all Blend procedures and settings
should be identical on BOTH projectors.
1. Start with 2 projectors. Display full white field test pattern from both.
2. In the Edge Blending submenu, enable Edge Blending by entering a checkmark in
the top checkbox.
3.
SET STARTING POINTS FOR ADJUSTMENT
Set all blend widths to 0.
Go to "More" and set everything in the Edge Blending (2) menu to 50.

4. : On one projector, increase the Blend Width for an overlapping

edge (for example, if the projector's image is on left, its right edge overlaps the
adjacent image—adjust Right Blend Width). Use the same setting on the second
projector for this shared edge.
5. Re-adjust width (both projectors) until the overly bright band at the midpoint of the
overlapping blends disappears or just changes to very light gray. For the shared
edge, use the same Blend Width setting on each projector. If the "best blend"
appears to be between two settings, choose the wider setting for both projectors.
6. If the blended region appears too dark or light in relation to the rest
CHECK BLEND:
of the image:
Increase Blend Midpoint in both projectors to "lighten" the overall blend,
decrease to "darken" the overall blend.
Adjust Blend Shape in both projectors to fine-tune change the amount of mid-
gray intensity (as opposed to black/white) in the blend.
7. Repeat with remaining projectors / overlaps.
8. Check completed display wall with the desired external signal.
9. Adjust mechanical alignment if necessary to maintain perfect pixel-on-pixel
alignment over time.
