you are combining images from multiple projectors on a network, you
can assign one projector as the "master" and automatically adjust
all the images to match the "master" image. If the projectors are
not connected to a network, you can match each projector's images
sure all networked projectors are connected using LAN cables and
have been assigned an IP address. Also disable Sleep Mode on each
projector so they do not turn off during adjustment.
