HDMI grabbers got cheap, usb based ones start around 1200円.

Based on Edwards reply,
what could one think of with HDMI grabbing (not saying all of
this would work out, but it's in technical reach):

- Having just one monitor, so grab the signal of others and then
   display then on the one running monitor
- building KVM devices with HDMI grabbers and raspi: connect a
   system via HDMI and usb to the raspi, and the raspi can not
   only grab HDMI but also emulate usb mouse/keyboard to that
   connected system
If you could combine it with power control functionality it could make a pretty cool DIY iLO[1] alternative. Though it looks like you can do most of that with Intel Management Engine[2].

I was interested in using it as a transparent pass-through device so you could plug it between the presenters laptop and projector and use that as a source for OBS[3], so you could combine video of the presenter and slides.
