1. Start with two full-screen projector images overlapped by approximately 12/5%-
25% each. Display full white field test pattern from both.
2. In the Edge Blending submenu, enable the top checkbox to activate all controls.
NOTE: If the
optional Christie
TWIST module is
installed, a pull-
down list
replaces this
checkbox (see
right). Select the desired user-defined blend created for your current warp; no
further blending at the projector is required. Or, to simply edge blending a non-
warped flat image, select "Standard" and continue with Step 3.
3.

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 effect 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 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.
