Two front ADB device ports and rear ADB pass-through port.
Speaker detail
Speaker detail	Stereo speakers with ported bass-reflex enclosure; Service Source states greater than 90 dB SPL at 1 kHz at 0.5 m, and 80 Hz–17 kHz ±6 dB response. These are maker audio claims. TIL's ambiguous 5 volts RMS wording is not converted to watts.	–

Size with stand
Size with stand	Service Source 553 × 484 × 545 mm, each ±3 mm (height × width × depth); archived TIL instead gives 55.5 × 48.5 × 59.5 cm. Both are maker figures with differing depth.	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	Service Source gives 35 kg (77 lb); archived TIL gives 35.4 kg (78 lb) for the display and 41.9 kg (92.1 lb) fully boxed. Main field retains Service Source monitor weight; shipping weight is not substituted.	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, contrast and five on-screen control buttons; bass, treble, volume, microphone and speaker mute. Additional picture controls through Mac Monitors & Sound panel or Windows on-screen controls. Automatic power-on degauss.	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	Service Source 190 W maximum; archived TIL instead 180 W operating maximum, less than 30 W standby and 5 W with speakers off or 30 W with speakers on in suspend/CPU energy-saving	Maximum 165 W; less than 15 W in Energy Saver mode
Power supply
Power supply	Service Source 90–264 V AC, 47–63 Hz; TIL instead separates 90–132 and 198–264 V bands. 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 7.1 or later, 68040 or later Macintosh processors for AppleVision software; Windows 95 compatibility via supplied adaptor. Maker 5 May 1997 press release expected 850AV availability in June, while non-AV 850 was immediately available; actual first retail month remains unverified, so year 1997 is retained. Service Source says November 1997 ColorSync AV rename alone changed no product hardware. No duplicate renamed model or inferred successor link. Brightness and contrast ratio unpublished.	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.
