Panel
Panel	LCD (TFT active-matrix LCD; Apple does not identify the panel subtype)	CRT (Nominal 21-inch Sony Trinitron aperture-grille CRT with a 19.8-inch viewable image; 0.25–0.27 mm variable aperture grille pitch. Vertically flat screen, without a fixed native pixel matrix.)
Pixel pitch
Pixel pitch	–	Variable 0.25–0.27 mm aperture grille pitch
Supported signal modes
Supported signal modes	–	Supports 1600 × 1200, 1280 × 1024 and 1024 × 768 at up to 85 Hz; 1152 × 870 and 832 × 624 at up to 75 Hz. Horizontal scan 31–107 kHz; vertical scan 48–120 Hz. These are selectable CRT signal modes, not a fixed native matrix or one native refresh rate.

Weight with stand
Weight with stand	5.5 kg	35 kg
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 datasheet'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/system startup and sleep, plus two brightness buttons on underside of display; software colour calibration through USB	Power, brightness and contrast; compatible Mac software supplies geometry, convergence, degauss, white-point and calibration adjustments
Colours
Colours	Translucent Graphite and white; distinct digital DVI hardware rather than a colour-only revision	Translucent Blueberry and white enclosure
Power and support
Power use
Power use	Below 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.	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, 100–240 V AC at 50–60 Hz; mains frequency is not a published display refresh rate	90–264 V AC, single-phase 47–63 Hz; mains frequency is separate from display refresh
Software
Software	Apple 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.	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.
