The Apple Studio Display 15 is Apple's first desktop flat-panel display: a 15.1-inch TFT active-matrix LCD with a fixed 1024 × 768 resolution, an external power adapter, and inputs for S-video and composite video as well as the computer.[1] Apple made three versions of it. The original (Rev. A, in dark blue and grey, "azul") and the Rev. B of January 1999 (translucent blue and white, with a VGA connector) have the same internal circuitry. The DVI version of December 1999, in graphite, has a digital DVI input and a USB hub and drops the video and audio connections.[2]
Apple's DVI Service Source dates the original to May 1998.[2] Wikipedia gives its introduction as 17 March 1998, at the Seybold Seminars alongside the Power Macintosh G3/300, at US$1,999, and says a later 15-inch Studio Display with the Apple Display Connector and a clear easel stand followed in July 2000.[3]

Hardware
[edit | edit source]The panel is a 15.1-inch TFT active-matrix LCD with a native 1024 × 768; Apple quotes typical brightness of 200 cd/m², contrast of 200:1 and viewing angles of 120° horizontal and 90° vertical.[1] Power comes from an external adapter; the Rev. A and Rev. B use adapter 922-3147 and the DVI version 922-4166.[1][2] Two stands came with each display, a desktop stand with tilt, swivel and height adjustment and a flip-out "picture-frame" stand.[1]
Apple did not supply parts inside the display: the display assembly is marked "not offered" in all three exploded views, and Apple's take-apart covers only the stands and the audio/video door.[1][2] In the US the display was repaired by mail-in through Apple's service facilitation process; in Canada the strategy was whole-unit replacement.[1]
Backlights and power
[edit | edit source]Apple's charts attribute a screen that has dimmed over time to failing backlights, which it gives an average life of 10,000 hours (about 40 hours a week for five years), and referred backlight replacement to Apple or an authorised dealer.[1] On the DVI version, a power light that repeats two short amber flashes and one long one indicates a backlight problem.[2]
Displays often turn up without their power adapter. TinkerDifferent members report that the adapter for the Rev. B (M4551) is rated 24 V at 1.875 A, that its plug is centre positive, and that the socket on the display cable takes a 5.5 × 2.5 mm barrel plug; one member ran the display from a generic 24 V 2 A supply through a barrel adapter, and another converted an old Verifone power adapter.[6] Check the polarity and voltage of any substitute before connecting it.

ComputerCompulsive: the blueberry display takes a 45 W, 24 V, 1.875 A adapter; later used a replacement with adapters. Fizzbinn: measured the plug as centre positive. PopeLeo: measured the barrel jack on the display as 5.5 × 2.5 mm; a generic 24 V 2 A supply with a female-to-female 5.5 × 2.5 mm adapter worked. Elemenoh: converted a Verifone power adapter with a female barrel connector. Community experience.
