Thunderbolt 2

Thunderbolt 2 replaces the original Thunderbolt as an input/output (I/O) interface for connecting peripheral devices to a computer, supporting high-resolution displays and high-performance data devices through a single, compact port.

Thunderbolt 2 was developed by Intel and brought to market with technical collaboration from Apple at the end of 2013.

Thunderbolt 2 uses a Mini DisplayPort connector and DisplayPort 1.2 protocol, supporting a top speed of 20 Gbps.

Thunderbolt 2 supports video streaming to a single 4K monitor, or to dual 1080p monitors, and is able to transfer a 4K video while simultaneously displaying it on a discrete monitor.

Because Thunderbolt I/O is based on DisplayPort technology, any Mini DisplayPort display plugs right into the Thunderbolt 2 port. Thunderbolt 2 also supports DisplayPort, DVI, HDMI, and VGA displays through the use of existing adapters.

Thunderbolt 2 is backwards compatible, which means that all Thunderbolt 2 cables and connectors are compatible with the original Thunderbolt.
