The projector is on the altar, with all other items that the Lord knows what they are.
Whenever I see priests using these projectors when they preach, it is as if, they are admitting that they are not effective preachers and they need the "help" of these technologies to preach during Mass.
Yeah why not?
You can be effective if you know how to drive home the message EVEN without the use of these technologies.
This is the Mass.
Not a retreat.
Not a seminar.
Not a classroom discussion.
And keep that damn thing off the portable altar!
It is not supposed to be there!
