Projector Blend Zone problem:

I ran into an issue where I removed the power cord from one of the center projectors. After that, the blend zone was no longer working correctly. There was a visual glitch like there was a straight line visible in the middle of the center projectors.

Jason Keeney pointed out that I can connect the projector remote control (wired), and in the projector menu, there is a blend zone feature. He said even if says “enabled”, that you turn it off, and then turn it on again. That seems to resolve that kind of issue.
