Other connectionsVGA computer video input, separate RCA composite and 4-pin DIN S-video inputs, left/right RCA audio inputs and mini-stereo audio output. Two downstream ADB sockets on desktop stand; no USB hub. Unlike the original Rev. A, computer video uses a VGA connector rather than Apple's 15-pin D-sub connector.Integrated ADC cable carries digital video, power and USB; two powered downstream USB ports

Size with standDesktop stand, 39.9 × 38.1–49.0 × 24.9 cm (width × height × depth). Picture-frame stand, 15.7 × 11.6 × 6.9 inches, weighing 3.5 kg. Apple technical note's metric picture-frame height is inconsistent with its inch figure, so the published imperial dimensions are retained.44.7 × 43.9 × 17.6–24.9 cm (width × height × depth)
ControlsPower, brightness, graphics/video source toggle, reset and on-screen display navigationTouch-sensitive system power control
ColoursTranslucent Blueberry and ice-white enclosure; distinct from original Azul and later Graphite/DVI revisionsCrystal-clear acrylic enclosure with silver-coloured frame
Power and support
Power useDisplay operating consumption below 35 WArchived Apple support sheet specifies maximum 40 W operating and 5 W or less in energy-saving mode. Original May 2001 French datasheet instead gives maximum 50 W and less than 35 W respectively; these surviving maker figures conflict.
Power supplyExternal power adaptor; mains frequency does not describe display refresh rate24.5 V or 28 V DC through ADC, from Apple's archived technical specifications
SoftwareApple support dates introduction to 5 January 1999 and the revision-specific technical note identifies the 1999 San Francisco Macworld launch. January precision is retained because a separate exact first-sale day has not been established. Native 1024 × 768 accepts 60, 70 or 75 Hz. Apple Technical Information Library article 30460 explicitly distinguishes this 200 cd/m², 5.5 kg revision from original Rev. A (180 cd/m² and 4.5 kg). PowerPC Mac with Mac OS 8.0 or later, or Windows 95/NT.Announced 21 May 2001 with first shipments expected in early June; June is used for retail timing. Native refresh is unpublished and omitted. Requires an ADC-equipped computer; Apple's later support sheet also lists compatible DVI Power Mac G4 and PowerBook G4 systems through the powered Apple DVI to ADC Adapter M8661LL/A. Co-marketed with the 15-inch ADC display, so no direct predecessor link is inferred.
