I apologize for my mistake in the previous message. Here is the corrected version:
"When we include a string cue in the timeline containing video files, Dxm control, and other elements."
For the password projection, I have already turned it off. Regarding the signal range conflicts, I don't think they are related, as the range I'm using is within the specification of the LAN cable. Lastly, the model of the projector we are using is Epson PU1008B.
