how do these things work...
are parts of it on one..then next part on the other or do both scroll the same thing and he just turns his head when he wants to and catches on the other screen
why is he using two?
Usually, when two of these are set up, one is on either side of the lectern so that the speaker can look around at the audience and always be able to see one, so the same text would be on each one. I am not near a TV at the moment, so I don’t know if he is using one or two.
