I've heard newer HDMI standards have HDMI Fast Switching. Skimming over the first URL google gave me[1] it sounds like the slowness is because of HDCP (HD Content Protection). Although, it sounds like it will theoretically take it from ~10seconds to maximum of 2 (average of 1) for proper implementations.

- ajross 9y agoLooks like "HDMI fast switching" just means "open all the input connections all the time", which is sort of a hack. But yeah, that seems plausible. Of course, in the time it takes for my television to initiate a secure transaction channel with the input hardware on the other side of the cable, my ?!%!? Netflix app has done a arguably more secure transaction with a server on the other side of the continent. Sigh.

- frozenport 9y agoUgg not this thing again. There are highspeed monitors and projectors that can send data faster. I know of projectors that run at 1khz used for fringe projection interferometry or rapid stimulation of optogenetically tagged nuerons. In principle, local response times can be faster while packets are bound by more fundamental things like the speed of light.
