Left: standard MicroUSB AB port
Right: standard MicroHDMI port
Middle: standardized charging port/support
the distances between the ports awill be standardized. the HDMI port will handle video and digital audio, while the USB port will handle communications.
the charging support will be designed to withstand the weight of the device without bending, and is tapered and grooved to make aligning very easy.
the charging part will have sufficient pins needed to communicate with the device, so it can on demand output 5V, 10V, or whatever the device requests. will also slow to trickle when told to do so.
the usb and hdmi ports could have some sort of spring below, to ensure a proper connections.
Ideally this is standardized with little or no licensing fees, so that most companies are free to adopt this.
