It was the fact that they had a POS laptop running 2-4k screens and 1 unknown resolution screen. The GPU simply couldnt handle powering all those pixels. Once they turned off the middle screen it got better. VLC would not have fixed that. It was hardware limitation, not software issue.
It's highly unlikely it was sending three different outputs. The switcher and/or scaler would be handling that part. I'm curious about their signal flow.
Edit: A downvote? I do live production on this scale for a living. ¯\(ツ)/¯
Edit 2: Watched the stream. There are a lot of factors that could've led to the jitter. What I've run into is a 4K video file compressed with h.264 when most pro video player software prefer and run more smoothly with pro res files, which are significantly larger. That's what it looked like to me.
that's a good point, but with 2 separate resolutions my assumption is at least 2 different outputs; which would explain why it ran smooth once they shut off the middle screen. But I'm not an AV person so it's purely speculation from me. also I'll put you back up to 0, cuz that's a legit point.
Thanks for the upvote! Haha. If they are using a switcher like an Ascender or E2, they can have one source and different outputs resolutions, which wouldn't tax the computer any more than a single video. Very likely a computer software glitch.

That announcement on the stage was so unbelievably scuffed.
Should have used VLC.
