I just have a ChromeCast in each room that I lecture in. Easy to bounce a tab over to the big screen, and it turns on the TV/projector. It also helps prevent notification or other screen sharing related mishaps.

My biggest complaints about this approach are that I can't easily see speaker notes (I have a fiddly workaround that I can use if I need it, but it would be nice if Google Slides would support the ChromeCast use case a little better..) and that the TVs/projectors tend to screw around for 10-15 seconds before automatically choosing the right source.

would phone work?

I know I can open other tabs to look at the presentation, so I assume it would. But it's not good optics for me to have a phone out when I ask my students not to do so.

I can get a speaker notes and a normal presentation tab open and cast one of them, but they all jump around and do the wrong thing on my screen (wanting to maximize, etc) and require a lot of coercion; too much time to start a normal lecture.
