Power and support

Power use
Maximum 180 W operating; less than 30 W standby; less than 5 W when the computer is in energy-saving mode
Power supply
90–264 V AC, single-phase 47–63 Hz; mains frequency is separate from display refresh
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 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 Brightness and contrast ratio are unpublished and omitted; no pixel density is assigned to this CRT.
