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.
NOTE:
If the best blend appears to be between 2 settings, choose the wider setting for both
projectors.
6. 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-gray intensity (as opposed to black/white) in the blend, adjust Blend
Shape in both projectors.
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.
NOTE:
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%.
3.2.5 Color Adjustments
The default configuration for StIM/SIM projectors has ArrayLOC enabled and configured to display a
reasonably saturated gamut at the maximum brightness that all the projectors in the array can support. If you
need to make further adjustments to the projector colors, see the
Bright/ColorLOC Setup Walkthrough and
Array Troubleshooting diagrams in the Matrix StIM/SIM User Manual (020-100306-XX) .
3.2.6 Black Level Blending
Brightens the center regions to match adjacent blend regions when edge blending multiple projectors. The
Black Level Blending submenu provides controls that allow you to adjust the black level hues of multiple
adjacent projected images to create one large seamless display.
NOTE:
Adjust edge blending before adjusting black levels. Blinders are recommended for fixed installations.
Do not use black level blending if Twist was used for the geometry.
Black Level Blending Procedure
NOTE:
The zones in the Black Level Blending menu correspond to the Edge Blend zones. If a given Edge Blend
zone width is set to 0 (i.e. no blend on that side) then the corresponding BLB zone is disabled. It only becomes
accessible when that Edge Blend zone is active.
1. Start with 2 projectors. Select the black test pattern for both projectors from the Geometry and Color
submenu.
2. In the Black Level Blending submenu, enable black blending by putting a check mark in the check box for
each projector.
3. Set the blend width.
4. Working with 1 projector at a time, use the center brightness slide bar to adjust the center brightness of the
non-blended region, so that the center intensity matches that of the brightest blended region (the center of
all images when blending a 2 x 2 display is the target area).
5. You can choose which of the next 4 options, Top, Bottom, Left, Right, to use depending on which edge of
the projector you are working with has been edge blended. The blend width can be adjusted to line up
properly but by default it corresponds to the edge blending setting determined for that edge.
