Description
By default the multifunction display automatically selects an
available WiFi channel. If you're experiencing difficulties with
wireless video streaming it may be necessary to manually
specify a WiFi channel for both the multifunction display and the
device you want to stream video to.
Display streaming must be enabled before you can stream video
from the multifunction display to an iPad or iPhone.
