Size with stand
Size with stand	January 1999 maker datasheet gives 41.1 × 42.7 × 44.7 cm (width × height × depth); archived support sheet instead lists 18.9 × 16.5 × 16.9 inches (height × width × depth), an unresolved maker conflict	51.1 × 56.6 × 55 cm (width × height × depth), January 1999 Blueberry datasheet; later Graphite enclosure dimensions differ
Weight detail
Weight detail	January 1999 M6221LL/A datasheet specifies 20.8 kg (45.9 lb); archived Apple support sheet instead lists 48 lb. The model-specific datasheet metric figure is used.	–
Controls
Controls	Power, brightness, contrast, on-screen geometry, convergence, degauss, moiré and colour-temperature controls	Power, brightness and contrast; compatible Mac software supplies geometry, convergence, degauss, white-point and calibration adjustments
Colours
Colours	Translucent Blueberry and white enclosure; the later August 1999 Graphite revision has the same performance and internal circuitry according to Apple's service manual	Translucent Blueberry and white enclosure
Power and support
Power use
Power use	January 1999 datasheet specifies maximum 150 W operating, less than 15 W standby and less than 5 W with the computer in energy-saving mode. Archived support sheet instead gives maximum 120 W; this maker conflict is retained.	Maximum 180 W operating; less than 30 W standby; less than 5 W when the computer is in energy-saving mode
Power supply
Power supply	January 1999 datasheet specifies 90–264 V AC, 47–63 Hz; these are mains ratings, not display refresh rates	90–264 V AC, single-phase 47–63 Hz; mains frequency is separate from display refresh
Software
Software	Maker announced the new Studio Display family on 5 January 1999; January retail precision is used because a distinct first-sale day is unconfirmed. January datasheet lists Power Macintosh G3 with Mac OS 8.0 or later. Brightness and contrast ratio are unpublished and omitted; no pixel density is assigned to this CRT.
