NOTES: 1) Before attempting to work with edge blending software functions, align the projectors/images by
correctly overlapping the displays from your intended external source.
uniformity.
IMPORTANT! For a shared edge, all blend procedures and settings should be identical on both projectors.
1. Start with two 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 check box.
SET STARTING POINTS FOR ADJUSTMENT
3.
a. Set all blend widths to 0.
b. Go to More and set everything in the Edge Blending menu to 50.
SET BLEND WIDTH
4.
the projector 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 grey. For the shared edge, use the same Blend Width setting on
each projector.

CHECK BLEND
6.
a. Increase Blend Midpoint in both projectors to "lighten" the overall blend, decrease to "darken" the
overall blend.
b. Adjust Blend Shape in both projectors to fine-tune change the amount of mid-grey 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. If necessary, adjust the mechanical alignment to maintain perfect pixel-on-pixel alignment over time.
In applications where you are projecting only white or light images, the Blend Width may be slightly higher—
set according to how much overlap you have between images. Use the following as a guide (examples show
overlapping width only—values for overlapping height will differ).

On one projector, increase the Blend Width for an overlapping edge (for example, if
