Samsung has TVs with the "smartness" in a separate box outside the TV and the display is just a display with one connector. Something like this should be a standard.
The One Connect Box has all the ports including power, HDMI, ethernet, USB etc. and the TV has just one proprietary port where you connect the One Connect Box.
I'm not sure that's what the parent commenter was asking for.
That is not a step forward.
Of course you can also just by an external Nvidia Shield unit and connect it by HDMI, like you can now.
