The Apple Thunderbolt Display is a 27-inch flat panel computer monitor sold by Apple Inc. from July 2011 to June 2016. It replaced the former Apple LED Cinema Display. New to the Thunderbolt Display was the switch from Mini DisplayPort and USB to a single Thunderbolt connection for data transfer between computer and display. The increased throughput from switching to Thunderbolt enabled inclusion of a Gigabit Ethernet port and a FireWire 800 port on the display. Older model Macs introduced prior to 2011 with Mini DisplayPort and the single USB-C retina MacBook are incompatible with the Thunderbolt Display. Apple Thunderbolt Display was succeeded by the Pro Display XDR on June 3, 2019 at the World Wide Developers Conference.
