Last evening we ran into problems projecting the presenter's slides onto the room's monitor.
The Wikipedia entry on Miracast claims Google dropped support for Miracast with Android 6 (Marshmallow)
That's very strange. I did my January presentation using my phone via Miracast, and I haven't had a version upgrade lately; my OnePlus 5 was on version 9 / Pi throughout. (Note that after the meeting, someone, probably Ivan, rebooted the monitor, at which point I suddenly *was* projecting my phone screen to the monitor. That wasn't an utter surprise; I was trying to do so ;-)! ) It seems as though we need some alternative handling, as we're running into the trouble that people are bringing laptops with newly discovered interfaces (I think this time it was USB-C) for which we had no adaptor available. I'm not quite sure what the best alternative is; lurking in my head is to pull out a ChromeCast (that speaks HDMI, and can be plugged into a USB port), in the hopes that we could push slides over to this.

Alternately, maybe a Raspberry Pi could do an apropos job, but it needs to NOT need a lot of setup to be "A/V-friendly." -- When confronted by a difficult problem, solve it by reducing it to the question, "How would the Lone Ranger handle this?"
