and continue with Step 3.
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. Set Blend Width. On 1 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. Check Blend. 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.
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.
• Recommended overlap is 12.5% - 25%
