I judged a Science fair last weekend. You are SOOOO right.

What's missing in the monitor bandwidth issue is that no attempt is made to make use of what mpeg does all the time. Most of the screen does not need to be updated at anything like the 60 Hz refresh rate that's common. Unless your real goal is fast moving games it is quite possible to place the imaging hardware inside of the monitor where it can accept the likes of open GL instructions to vary the video RAM that's inside of the monitor.

The X-11 folks in the UNIX world do that now and they once did it over the likes of RS232 cabling to dumb terminals.

Today we have flat panel monitors with fast microprocessors that can convert VGA style video back to digital and display it. Why can't those processors accept graphics commands as if they were being sent to a video card? The reduction in bandwidth would be dramatic. For text editing it would be a few kilobits per second. With some extra RAM, scrolling could be handled within the monitor. So could MPEG decoding for a lot of the entertainment that seems to be the important thing these days.
