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.	15-pin mini D-Sub VGA video connector with supplied VGA-to-Macintosh adaptor

Size with stand
Size with stand	Desktop 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.	51.1 × 56.6 × 55 cm (width × height × depth), January 1999 Blueberry datasheet; later Graphite enclosure dimensions differ
Controls
Controls	Power, brightness, graphics/video source toggle, reset and on-screen display navigation	Power, brightness and contrast; compatible Mac software supplies geometry, convergence, degauss, white-point and calibration adjustments
Colours
Colours	Translucent Blueberry and ice-white enclosure; distinct from original Azul and later Graphite/DVI revisions	Translucent Blueberry and white enclosure
Power and support
Power use
Power use	Display operating consumption below 35 W	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	External power adaptor; mains frequency does not describe display refresh rate	90–264 V AC, single-phase 47–63 Hz; mains frequency is separate from display refresh
Software
Software	Apple 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.	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 M6204LL/A datasheet requires the new Power Macintosh G3 with built-in USB and Mac OS 8.0 or later. Brightness and contrast ratio are unpublished and omitted; no pixel density is assigned to this CRT.
