Analogue CRT has no fixed native pixel matrix.)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)
Pixel pitchMaker 0.25 mm aperture-grille pitch and 0.26 mm stripe pitch, retained as distinct published descriptions–
Supported signal modesCurrent maker support and Service Source list 640 × 480 at 60 or 66.67 Hz, 800 × 600 at 60.31 or 75 Hz, 832 × 624 at 74.55 Hz, 1024 × 768 at 60 or 74.93 Hz, 1152 × 870 at 75 Hz and 1280 × 1024 at 60 or 75.03 Hz. August 1997 Apple Facts additionally lists 1280 × 960; maximum supported format depends on the computer. These are supported analogue signals, not native resolution or native refresh.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.
Screen coatingMaker antistatic and antiglare surface treatment; launch press release describes antireflection coatingAntiglare and antistatic surface treatment
CalibrationApple DigitalColor self-calibration against factory measurements compensates for CRT phosphor ageing and ambient lighting; ColorSync profiles support colour matching between devices. Maker variable white point 4100–9300 K. No unpublished headline brightness inferred.–

Size with standCurrent support gives 16.8 × 16.2 × 17.6 inches (height × width × depth); August 1997 Apple Facts and exact TIL pair these with 42.7 × 41.1 × 45.2 cm. Service Source instead publishes 425 × 410 × 455 mm and a differing inch set. Later May 1998 brochure gives 44.7 cm depth. Maker dimensional differences retained.Maker support gives 17 × 16.2 × 16.9 inches (height × width × depth); Service Source also gives 431 × 412 × 428.5 mm
Weight detailService Source publishes 22.5 kg (50 lb). Current support gives 49 lb; August 1997 Apple Facts pairs 49 lb with 22.0 kg, while exact TIL and May 1998 brochure pair it with 23 kg. Maker differences retained without converting pounds or inventing a hardware revision.Service Source publishes 17 kg (37.5 lb)
ControlsFront power, brightness, contrast and three on-screen control buttons; further size, centring, convergence, rotation, pincushion and white-point controls through AppleVision software or PC on-screen controls. Automatic degauss at power-up.Front power, brightness, contrast, on-screen display select/adjust and enter controls for geometry adjustments
Power and support
Power useCurrent support and Service Source give 130 W maximum; exact TIL and May 1998 brochure instead state 125 W maximum and less than 60 W standby. Exact TIL gives 0 W computer energy-saver mode, while brochure gives less than 5 W; conflicting maker claims retained.Maximum 120 W
Power supplyCurrent support and Service Source specify regional 100–120 or 220–240 V AC, 50–60 Hz; exact TIL and May 1998 brochure instead give 90–264 V AC, 47–63 Hz. Mains frequency is not display refresh.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.
SoftwareMac OS 7.1 or later with compatible 68040 or PowerPC hardware for launch AppleVision functions; later ColorSync brochure requires Mac OS 7.5 or later. Service Source explicitly says the November 1997 ColorSync rename was the only product change, so no duplicate rename entry is created; later TCO 95 plastics are qualified separately. Maker 5 August 1997 press release, reproduced in October Mini'app'les, states immediate availability in most countries. Apple Facts explicitly identifies this as replacing AppleVision 1710. Exact front photograph is Apple's launch-era 750 illustration.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.
CertificationsOriginal launch TCO 92, MPR II, EPA Energy Star and VESA DPMS. Service Source identifies TCO 95 plastics from January 1998 for the non-AV ColorSync model only, with certification determined by the rear housing marking; later certification is not assigned to every launch unit.TCO 95 and US EPA Energy Star
