USB-C chargingNoneNone
USB ports–2 × USB-A
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 supplies digital video, USB data and power; two downstream powered USB ports. No separate analogue computer, composite, S-video or audio input.

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.41 × 40.3 × 17.2–25.9 cm (width × height × depth), from Apple's May 2001 French datasheet; archived support page rounds to 15.8 × 16.1 × 6.7 inches (height × width × depth)
ControlsPower, brightness, graphics/video source toggle, reset and on-screen display navigationTouch-sensitive system power, sleep and wake control, plus brightness adjustment
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 WMaximum 50 W operating; 35 W or less in sleep mode, from Apple datasheet
Power supplyExternal power adaptor; mains frequency does not describe display refresh ratePowered through ADC; datasheet specifies 28 V DC ±1.5 V, with no separate monitor mains cord
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.Apple's 19 July 2000 US announcement says available immediately; Japanese first retail was 5 August, so the earlier US sale date is used. Brightness, contrast, weight and metric dimensions follow Apple's surviving May 2001 datasheet for M7928ZM/A. Neither this datasheet nor the archived support page specifies native refresh, so it is omitted. Requires Power Mac G4 or Power Mac G4 Cube with ADC in maker launch documentation; other digital sources require a compatible powered ADC adaptor.
