Size with stand
Size with stand	Desktop stand, 39.9 × 38.1–49.0 × 24.9 cm (width × height × depth), from Apple's April 1998 datasheet. Service manual lists slightly different metric dimensions beside the same imperial figures; datasheet retained here. With included picture-frame stand, 15.7 × 11.6 × 6.9 inches (width × height × depth), weighing 2.3 kg.	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
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, graphics/video source toggle, reset and on-screen display navigation; software controls for white point, black level, tracking, positioning and sharpness	Power, brightness, contrast, on-screen geometry, convergence, degauss, moiré and colour-temperature controls
Colours
Colours	Original translucent Azul blue enclosure; not the later Blueberry or Graphite models	Translucent Blueberry and white enclosure; the later August 1999 Graphite revision has the same performance and internal circuitry according to Apple's service manual
Power and support
Power use
Power use	Display operating consumption below 30 W, from the revision-specific Apple technical note; separate 45 W power adaptor	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.
Power supply
Power supply	External power adaptor, 100–240 V AC at 50–60 Hz; this mains frequency is not the display refresh rate	January 1999 datasheet specifies 90–264 V AC, 47–63 Hz; these are mains ratings, not display refresh rates
Software
Software	Apple announced this model on 17 March 1998 for worldwide availability in early May; Apple's archived support sheet gives introduction on 7 May 1998. Release month follows retail availability rather than announcement. Native 1024 × 768 accepts 60, 70, 74.9 and 75 Hz in the original maker manual. Apple Technical Information Library article 30460 explicitly distinguishes original Rev. A (180 cd/m², 4.5 kg desktop stand and below 30 W) from 1999 Rev. B (200 cd/m², 5.5 kg and below 35 W). The April 1998 datasheet and archived support sheet give the later figures; the later revision-specific technical note is followed here. PowerPC Mac with Mac OS 7.5 or later, or Windows 95/NT; see manual exclusions for older Macs and graphics cards.	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.
