DisplayPort Packet Swarm
So, there is now DisplayPort and miniDisplayPort.
The last video connection tech am somewhat familiar is DVI (digital video interface) year ~2000, the era of switching from analog to digital.
DisplayPort differ by it's the 1st video interface to use packets. Like TCP/IP. That means, it's easily extensible, cables can trivially splice or merge, can be transmitted to USB. Amazing. From analog to digital to packet swarm.
You wonder, are connector tech gonna kept changing every 5 years? what possibly could they change? You thought, finally we have a good connector/interface, but bang, they change again.
Also note, much of port/connector/interface/dongle change are driven by money, of corps and standard orgs. Those have patent royalties justly ask you for $, those don't, sing OpenSource song but gecha with membership fee.
