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 2 projectors. Display full white field test pattern from both.
2. In the Edge Blending submenu, enable Edge Blending by choosing Standard from the drop-down.
3. Check the Show Blending Overlap box on both projectors.
4. Set starting points for adjustment:
a. Set all blend widths to 0.
b. Go to Advanced Edge Blending and set all options to 50.
5. Set blend width:
a. On one projector, increase the Blend Width for an overlapping edge (for example, if the projector
image is on the left, its right edge overlaps the adjacent image—adjust Right Blend Width).
b. Use the same setting on the second projector for this shared edge.
NOTE: Recommended overlap is 12.5%–25%.
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.
6. Increase blend width (both projectors) until the overly bright band at the midpoint of the overlapping
blends is at 50% grey level. 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.
7. Check the blend and adjust as required:
• To lighten the overall blend, increase the Blend Midpoint in both projectors.
• To darken the overall blend, decrease the Blend Midpoint in both projectors.
• To fine-tune the amount of mid-grey intensity (as opposed to black/white) in the blend, adjust Blend
Shape in both projectors.
8. Repeat with remaining projectors / overlaps.
9. Check completed display wall with the desired external signal.
10. If necessary, adjust the mechanical alignment to maintain perfect pixel-on-pixel alignment over time.
