I need help getting Keynote to display all of its slides on an Epson PowerLite projector.
I am a av/computer guy in charge of several classrooms. I have been having trouble with multiple computers. Most recently 3 different new 15‑inch MacBook Pro 2.6GHz 6‑core 9th‑generation Intel Core i7 processor running Keynote 9. When they present the projector stops recognizing and displaying content from the computer on some slides. This seems to be random. It displays to the projector properly on some but not all. We are connecting via a USB C port to HDMI via Apple USB-C Digital AV Multiport Adapter and/or a Amazon Basics counterpart.
