facing installations.
Option

• Be sure to perform this setting to use vertical projection.
• Projecting vertically without using this setting will shorten the useful life of the lamp
and other parts.
• Even if you complete this setting, vertical projection will result in a shorter useful life
of the lamp and other parts than horizontal projection.
Edge blending
Brightness and colors of overlapping edges of images from multiple projectors, which form a
blending area, can be adjusted for a more seamless appearance. For detailed instructions, see
"Projecting from Multiple Projectors at Once (Edge Blending)" (P163).
[Off] Disable blending.
[Adjust] Display the menu for blending area adjustment.
• Adjustment may not eliminate different colors or brightnesses in the blending area.
• For best edge-blending results, use all projectors in the same image mode and make
the following adjustments.
(1) Brightness, contrast, R/G/B gain and offset, black level, blending color, color
temperature, color level, color balance, sharpness, and gamma (P88)
(2) Color adjustment, by using 6-axis color adjustment (P91)
(3) Gamma adjustment, by fine-tuning gamma (P91)
(4) Corner adjustment, using keystone correction (P59)
