I can't decide if this belongs in this forum or in "Facility Operations," apologies if I chose wrong.
We have a large Epson projector hung from the ceiling in our auditorium, projecting onto a motorized screen that rolls down in front of our stage. Connection is accomplished by HDMI via a balun, with a splitter so that users can connect both in the booth and from the front of the stage (the stage connection is also through a balun). This was set up by our IT department a couple of years ago, and drives me crazy when it doesn't work properly. I think I have the booth connection under control, though even that is occasionally unreliable, but it's the HDMI connection on the front of the stage that gives us fits. We are experiencing intermittent connection loss/flickering with a variety of cables and different types of computers, even when the computer is sitting still with noone touching it. IT has failed to come up with a good solution, so I'm trying to troubleshoot.
Is there a better standard than HDMI to use for connection that would still be easily compatible with most of our users? I'm loathe to go wireless, but I've been having good success with projecting from laptops to installed screens in other classrooms, and wondering if that might work better. I wish I could convince everyone to just use the installed computer in the booth, but they seem intent on using laptops from the stage.
Thanks for any suggestions!
