Seems archaic, yet it’s still the best for sharing BIOS screenshots with the only change that I’m using my phone to take the picture.
Might be potential in those devices that sit between a source and display. I don’t even know what they’re called. I saw a guy using one for PowerPoints off his laptop for a projector. It also let him freeze the displayed image while he did stuff on his laptop audience couldn’t see. I figure modern models might even do things like saving stuff on USB, online sync, photos every so many fractions of a second to catch a running process/activity, and so on.
Have no idea since saw it long ago. Came back to mind when you mentioned BIOS’s with those fast-moving, loading screens. Could also even be useful as an add-on to diagnostics or repair software looking at video output similarly to how other tools look at CPU, disk, and network activity.
