Curiosity as well. At a live presentation I went to a couple of years back, his laptop couldn't connect to my company's projector. The first thing he said was along the lines of, "Fascinating! I've never come across this specific problem before!" Literally every other presenter I've seen facing such an issue would bemoan technology or crack a joke about things 'always' being broken.

He actually is interested in this and talks about it in his recent blog post here https://blog.stephenwolfram.com/2019/02/seeking-the-producti...
Search for EDID
> for high-profile, high-production-value events, I have a little box that spoofs EDID strings to force my computer to send a specific signal, regardless of what the projector seems to be asking it for.
Wow, that was totally unexpected! Thinking back (circa 2013), I wonder what video quality lessons he got out of that particular set-up. From what I recall, we had something awful:
1) Presenter computer plugged into some sort of video capture hub, connected to computer A with video capture card that would composite camera video with slides. 2) Separate computer B running remote desktop into that computer to broadcast to the web. 3) Another computer C, also with remote desktop, connected to the projectors.

Serious productions bring all video signals into a switcher [0] and compose their outputs to screens/projectors/capture devices from there. You can tell something like this is in use if there are sensible transitions between different presenters' computers, and the audience doesn't have to watch the resolution-negotiation phase.
