PanelLCD (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–Variable 0.25–0.27 mm aperture grille pitch
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.
Screen coating–Antireflective and antistatic screen coating
Calibration–Internal measurement system adjusts the electron beam to maintain factory calibration; stores ColorSync profiles. Includes an ambient-light tool, variable 4100–9300 K white-point selection and gamma-curve adjustment.

Power and support
Power useArchived 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.Maximum 180 W operating; less than 30 W standby; less than 5 W when the computer is in energy-saving mode
Power supply24.5 V or 28 V DC through ADC, from Apple's archived technical specifications90–264 V AC, single-phase 47–63 Hz; mains frequency is separate from display refresh
SoftwareAnnounced 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 Native refresh is unpublished and omitted.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.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 Brightness and contrast ratio are unpublished and omitted; no pixel density is assigned to this CRT.
