Nice! Everything I'd seen before was DVI.

What about HDMI input? What I'm imagining is an HDMI freeze button, to buffer a single frame. Many projectors have that feature built in, but some don't, and I wish I could build it as an external hardware device.

Huh. Why is that useful? (Since some projectors have it built in I imagine there's a use case I'm missing.) Splash screen while you figure out your presentation on your mirror but without the stress of your audience watching you click around?

When projecting song lyrics at church, and the worship leader says: "let's sing the chorus again with 'we' instead of 'me'" and I suddenly have to freeze frame, edit the text, and bring it up as quickly as possible.

I'm sure there are other use cases for a freeze button, and the idea of having it as a separate device is something so obvious to me that I'm surprised it doesn't already exist.

Aha, but the general idea is still "show the current thing while I'm futzing around to make the next thing happen"?

Yep that's the gist. I've also seen some small events using the computer background as the static logo; they can prepare the next deck while freezing the logo up on he screen.

I would live HDMI input also, but for different reasons. I want to process video from HDMI streams.

Mike Field has something in VHDL for this: https://github.com/hamsternz/Artix-7-HDMI-processing

I think https://github.com/timvideos/HDMI2USB-numato-opsis-hardware can do that (it's also FPGA based)
