  • Apple Cinema displays use their power LED (lower right corner) to inform a user about faults and errors. If any of them occur, the LED will blink in a certain Morse-style pattern. See “Apple Cinema Display Error Codes” for details.
  • The first Apple Cinema display model was the 22-inch Apple Cinema Display. This model was introduced in September of 1999 alongside the Power Mac G4. It used DVI for video input. The first Cinema display was enclosed in a high-density plastic frame with an easel-style stand. The display had a resolution of 1600 × 1024. This model was upgraded in July 2000, along with the Apple Display Connector (ADC) which ran DVI, USB, and 25V power through a single connector. The first model was eventually replaced by a 20-inch model on January 28, 2003. The 20-inch model sported a widescreen display with up to 1680 × 1050 resolution.
  • In 2006, Apple Cinema Aluminium Cinema displays had a silent upgrade that boosted the brightness and contrast ratios to 300/400 cd/m2 and 700:1.
  • These last Cinema displays were very desirable to photo and video professionals, because the anti-glare displays made by Apple had a true IPS 8-bit, (no dithering) back-lit panel.
  • Altogether, there have been three designs for the Cinema Display; one display featuring polycarbonate plastic and two displays featuring anodized aluminum. The first Cinema displays were designed to match the colorful plastic of the Power Mac G3 and G4. The next revisions were designed to match the more professional aesthetics of the Power Mac G5 and PowerBook G4. The last available design matched the uni-body Apple laptops, which were released in October of 2008.
  • Since Apple introduced its aluminum and glass models on October 14, 2008, the company removed the matte, anti-glare screen panels in all of its Cinema Display lineup, except for the 30″ Cinema Display. Apple no longer offers any equipment with a matte, anti-glare screen since October 2013, when the 15″ non-Retina MacBook Pro was discontinued. This decision caused concern among users who wanted matte screens for their particular area of work; particularly graphic designers, photographers and users who extensively view their screens. The Wall Street Journal referred to Apple’s removal of the matte screen as one of Apple’s worst design decisions.
  • Users could attach their display to alternate mounting solutions using the VESA Mount Adapter kit available from the Apple Store. It was possible to use the VESA Mount Adapter kit to prepare the display for attachment to many different VESA-compatible mounting solutions by simply following the instructions included with the kit.
  • Apple recommended to be very careful if a part of the screen was dim, or the screen does not have an image, as it might take several minutes for the display to reach full operating brightness. The user should make sure the display brightness controls were set properly. The brightness buttons on the side of the display should be used. It was also possible to choose Apple (K) > System Preferences, and then click Displays. If a portion of the screen remained dim after the display has warmed up, and the white or LED on the front of the display was flashing in a repeating pattern, Apple Inc. recommends contacting an Apple Authorized Reseller or Service Provider.
  • Ergonomics: Apple recommended adjusting the display in order to reduce glare and to accommodate the user’s physical size and shape. It also recommended arranging the display so the top of the screen is slightly below eye level when the user was sitting at the keyboard. The best distance from the eyes to the screen is completely up to the user, although most people seem to prefer 18 to 28 inches. The user should position the display by tilting it up or down to minimize glare and reflections on the screen from overhead lights and nearby windows.
