Can we please have HDMI monitors that include power and HDMI connectors to an internal pocket for compute units that will go inside their shells. Fans, too, that can be set on or off to cool the pocket. The companies can get together with a standard form factor or, if a company was Apple, it could do up proprietary shapes so only their "compute units" will fit in their monitors, and let the best approach win (or lose, as the case may be).
But seriously, if you need a screen that is 12" to 96" diagonal, and you are paying thousands for it, why are you worried about shrinking the thing that costs hundreds and generates images for that screen.
There. I feel better now.
