Weight with stand5.5 kg6.6 kg
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 datasheet'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/system startup and sleep, plus two brightness buttons on underside of display; software colour calibration through USBTouch-sensitive system power control
ColoursTranslucent Graphite and white; distinct digital DVI hardware rather than a colour-only revisionCrystal-clear acrylic enclosure with silver-coloured frame
Power and support
Power useBelow 35 W operating, from December 1999 Apple datasheet. Archived support page labels 35 W as Energy Saver consumption and leaves maximum unknown; datasheet's operating specification retained.Archived 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, 100–240 V AC at 50–60 Hz; mains frequency is not a published display refresh rate24.5 V or 28 V DC through ADC, from Apple's archived technical specifications
SoftwareApple service manual and revision-specific support note place this DVI model in December 1999; the August date repeated by some secondary histories is not used. Apple Canada's 6 December announcement says it could be ordered and was expected to ship before year-end; first retail month is retained without inventing a day. Native resolution is 1024 × 768; Apple's Japanese support sheet explicitly specifies 70 or 75 Hz at native resolution; the English archived support sheet and December datasheet omit the refresh rates. Maker compatibility is Power Mac G4 with ATI RAGE 128 Pro graphics and built-in USB, running Mac OS 9.0 or later. Maker support lists 15.1-inch viewable size while the datasheet rounds to 15 inches.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 Native refresh is unpublished and omitted.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.
