Just like the 24-Inch Thunderbolt before it, theApple 27in LED Cinema Display was designed as an “ideal companion” for MacBook, MacBook Pro and MacBook Air models as well as desktop Macs with a Mini DisplayPort (and it is not compatible with earlier Macs). The 27in LED Cinema Display features a Apple 27in glossy LED-backlit TFT active-matrix LCD display with IPS technology and an optimum resolution of 2560×1440. It has a 178 degree horizontal and vertical viewing angle, a “typical” brightness of 375 cd/m2, contrast ratio of 1000:1, and a 12 ms response time. It includes three USB 2.0 ports and a convenient single cable with three connectors (Mini DisplayPort, MagSafe, and USB 2.0), a built-in iSight camera with a mic and a 2.1 speaker system.
