DockPort
DockPort (originally codenamed Lightning Bolt[1]) is a backward-compatible extension of DisplayPort, adding USB 3.0 and DC power, in addition to DisplayPort's video and audio signalling. Standardised by VESA, it is the first royalty-free industry standard to combine these four interface functions in one connector.[2][3] DockPort was developed by AMD and Texas Instruments, two member companies of VESA, as a low-cost alternative to Thunderbolt, for use as a docking interface for laptops and other mobile devices.
The Texas Instruments HD3SS2521 is a DockPort controller that routes DisplayPort and USB 3.0 signals along with power over a standard DisplayPort cable. It was unveiled in 2013, and used as the basis of the final DockPort standard.[4] The docking, for instance, can provide MST hub implementation for multiple displays (through DisplayPort, HDMI, DVI, or D-Sub), a SuperSpeed USB hub, alongside audio and full bandwidth Gigabit Ethernet.
