Display
Screen size
Screen size	19.1″	16″
Panel
Panel	CRT (Original nominal 20-inch Trinitron CRT, 19.1-inch viewable image and 0.31 mm stripe pitch; no fixed native matrix. Later Revision B uses a different 0.26 mm tube and is not substituted here.)	CRT (Nominal 17-inch flat-square shadow-mask CRT with 16-inch viewable image and 0.28 mm dot pitch; no fixed native pixel matrix)
Supported signal modes
Supported signal modes	Apple's support sheet lists 640 × 480 at 59.95, 66.7 or 75 Hz; 800 × 600 at 75 Hz; 832 × 624 at 75 Hz; 1024 × 768 at 74.93 or 75 Hz; 1152 × 870 at 75 Hz; and 1280 × 1024 at 75 Hz. Service Source gives horizontal scan range 29–82 kHz and vertical range 50–150 Hz. These are supported CRT signal modes, not a native pixel matrix or native refresh rate; modes depend on the computer and adaptor.	Apple's support sheet lists 640 × 480 at 60, 66.7 or 85 Hz; 800 × 600 at 60 or 85 Hz; 832 × 624 at 75 Hz; 1024 × 768 at 60 or 75 Hz; 1152 × 870 at 70 Hz; and 1280 × 1024 at 60 Hz. Service Source additionally lists 800 × 600 at 72 Hz, 1024 × 768 at 70 or 85 Hz, and 1152 × 870 at 75 Hz rather than the support sheet's 70 Hz. Maker timing conflict retained. Horizontal range 30–70 kHz and vertical range 48–160 Hz in Service Source are scan ranges, not a native refresh rate.

Power supply
Power supply	Service Source specifies 90–132 or 198–264 V AC, 47–63 Hz; support archive instead gives the upper band as 198–260 V. These are mains ratings.	Service Source specifies 100–120 or 220–240 V AC, 50–60 Hz; later Apple support lists 90–134 or 198–260 V, 47–63 Hz. Source difference retained; mains frequencies are not display refresh rates.
Software
Software	System 7.1 or later; older Macs may need additional adaptors. Apple support identifies March 1994 introduction, and InfoWorld's 14 March 1994 shipping section reports rollout that week; month precision retained. Service Source distinguishes original 0.31 mm hardware from later Revision B 0.26 mm hardware with different deflection board, controller and power supply. No Revision B retail date is inferred. Brightness and contrast ratio are unpublished.	Mac OS 7.5 or later, Power Macintosh, Performa and Quadra with 68040 or later processor; Windows and MS-DOS VGA systems with adaptor. Maker support lists introduction on 8 October 1997, while TidBITS on 10 November 1997 describes that day's announcement and EveryMac flags the conflict. First retail month is not established, so year precision is retained. Maker brightness and contrast ratio are unpublished.
