Screen size	12.4″	19.1″
Panel
Panel	CRT (Nominal 14-inch spherical shadow-mask tube with 12.4-inch viewable diagonal and 0.28 mm dot pitch; Service Source describes P22-derived phosphor and polished surface treatment. Analogue CRT has no fixed native pixel matrix.)	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.)

Supported signal modes
Supported signal modes	Current maker support lists 640 × 480 at 60 or 66.7 Hz and 800 × 600 at 60 or 72 Hz. Original model M3935LL/A does not support 832 × 624; Service Source documents a November 1995 upgrade programme to Revision B supporting 832 × 624 at 75 Hz on eligible computers. October 1995 Apple Facts already lists that mode, qualified by computer support; it is not assigned to the original revision. These are analogue signal modes, not native resolution or refresh. Original scan range 31.5–48.1 kHz horizontal and 60–72 Hz vertical.	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.

Other connections
Other connections	Attached Macintosh DA-15 video cable; exact-model EveryMac specifies DB-15 and the two-row connector is visible in Ben Boldt's exact-model photograph. Service Source describes a 15-pin miniature D-type cable with separate sync; VGA/SVGA signal compatibility does not add a second physical VGA connector.	Macintosh 15-pin DA-15 analogue RGB cable; VGA computers need a video adaptor. Two front ADB device ports and rear ADB pass-through port.
Audio out
Audio out	Front headphone jack; Service Source identifies one audio input and one pass-through headphone/speaker output. Headphone insertion mutes the internal speakers.	–
Speaker detail
Speaker detail	Integrated front stereo speakers; Service Source publishes minimum 500 mW per speaker with 0.707 V RMS input and response ±3 dB from 100 Hz to 20 kHz. Maker description and Apple Facts confirm audio despite EveryMac's conflicting no-audio table entry.	–

Swivel

Size with stand
Size with stand	Apple Facts publishes 37.8 × 36.5 × 38.6 cm and 14.9 × 14.4 × 15.2 inches (height × width × depth), matching current support's inches. Service Source instead gives 378 × 365 × 380 mm with a differing set of inch values; maker conflicts retained.	Apple support publishes 18.7 × 18.7 × 19.7 inches (height × width × depth); Service Source separately lists 474 × 474 × 501.5 mm
Weight detail
Weight detail	Apple Facts publishes 11.3 kg (25 lb); current support also gives 25 lb. Service Source pairs 25 lb with 13 kg, a conflicting maker metric figure retained here rather than converted or silently selected.	Service Source gives monitor weight 30 kg (66 lb), distinct from the 36 kg boxed shipping weight. The later 1995 Apple Facts sheet for the 0.26 mm tube instead gives 29.7 kg.
Controls
Controls	Front power, brightness and contrast controls; horizontal/vertical shift and size controls behind the door. Automatic power-on degauss; maker describes a full degauss after power-off for at least 20 minutes.	Front-panel power, reset, brightness and contrast; image position, size, rotation, convergence and colour-temperature controls. Automatic power-on degauss.
Power and support
Power use
Power use	Maker 80 W maximum; Energy Star low-power mode supported, exact idle consumption unpublished	Maximum 165 W; less than 15 W in Energy Saver mode
Power supply
Power supply	Current maker support gives regional input ranges 90–132 or 198–264 V AC, 47–63 Hz; Service Source describes 90–132 V AC. Mains frequency is not display refresh.	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.
Software
Software	System software 7.1 or later; supported modes depend on Macintosh video hardware and adapters. Current maker archive dates introduction 15 August 1995, while EveryMac gives 7 August; actual first retail day/month remains unverified, so year 1995 retained. Service Source distinguishes original and Revision B hardware; no assumed direct predecessor or successor. Photograph is Apple's exact model illustration from October 1995 Apple Facts; physical revision not identified by that image.	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.
