connect to external tv monitor and show presentors notes in keynote
I have a MacBook Pro, OS 12.2.1.
I want to run a presentation using Keynote on a large screen tv monitor connected via an HDMI cable.
The screen needs to show the full-screen slides (presenter display) but the Mac only showing the current and next slides, and the presenter's notes.
I can get this to work with a separate LED projector (no problem) but I can't get it to work using a TV monitor.
How can I set it up to show two different screens (presentation slide for TV monitor) and current, next, and notes on the Mac?
