Edge Blending Procedure
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. 2) Match colors and the brightness
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 check mark in the top check box.
3. Set starting points for adjustment:
a. Set all blend widths to 0.
b. Go to More and set everything in the Edge Blending menu to 50.
4. Set blend width 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 grey. For the shared edge, use the same Blend Width setting on
each projector.
NOTE: If the best blend appears to be between two settings, choose the wider setting for both projectors.
6. Check blend if the blended region appears too dark or light in relation to the rest of the image:
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).
NOTE: Recommended overlap is 12.5% - 25%.

NOTES: 1) For defining or changing a User 1, 2, 3, or 4 color
performance or "gamut". Sometimes known as Comprehensive
Color Adjustment™. 2) Factory-defined primary color levels,
which ensure a specific color performance from projector-to-
projector, can be calibrated in the Service menu only. The
factory settings can be recovered with selection of "Reset to
Factory Defaults?" in the Color Primary Settings submenu
accessed via the Service menu (password-protected).
From the factory, the projector can utilize any of the three pre-defined color performance settings identified at
right (default = Max Drives), or colors can be driven on the basis of color temperature. For most applications,
