Edge-blending calculator
Combine several projectors into one canvas: see the total resolution, the size of each blend zone and how wide each projector's image must be.
How blending resolution is calculated
Total width = n × w − (n − 1) × overlap. Pixels in the blend zones are shared between projectors, so the canvas is smaller than the sum of all projectors. Learn more in Edge blending and multi-projector setups.
