But even for non-video use cases? Eg development, photo editing, where the fps isn't (probably) that important.

  Naive question: I can stream 4K to my tv over general-purpose 801.11ac (meant to be non-directional/line-of-sight). I'd imagine that a purpose built protocol/phy should be able to push even more bits in sub-1ft distance with direct LoS, no?

    I think the issue with the tv streaming example is that you’d have no idea what the lag time is, the delay would be two whole seconds but as long as the video doesn’t skip you wouldn’t even know, versus moving a mouse around which would make the smallest amount of delay extremely noticeable.

      Latency is a thing for sure. But we're talking a few inches of distance that the signal needs to travel, so I don't think it's a significant issue. The latency when "casting desktop" to TV is pretty tolerable (to the point that I hadn't noticed it until I read your comment).

        Try typing when casting for a visceral demonstration of the latency. Also you might not see it but that casting is generally very compressed video

    The video is encoding meaning that the number of bits transmitted is much smaller than if raw pixels were sent. Theoretically the same could work for streaming your desktop. But it would be very hard to do without causing noticeable lag.
