Overview
Released19871989
Display
Screen size12.8″14.2″
PanelCRT (Apple support specifies a nominal 13-inch Trinitron tube and 12.8-inch viewable diagonal; owner and service manuals instead call it 13-inch viewable. Service Source gives 0.26 mm aperture grille pitch, while TIL2165 and TIL8439 give 0.25 mm. Analogue CRT has no fixed native pixel matrix.)CRT (Nominal 15-inch monochrome CRT; Apple support gives 14.2-inch viewable diagonal and calls the tube shadow mask, while Service Source describes white P4 phosphor and a flat square screen. No fixed native pixel matrix.)
Colour depth–Service Source supports 1-, 2-, 4- or 8-bit analogue levels, with up to 256 greys at 8 bits per pixel; actual grey levels depend on video hardware. The original March 1989 launch notice lists lower video-card configurations and is not treated as a later display limit.
Colour modesOwner guide lists 256 colours with Macintosh Display Card 4•8 and 16.7 million with 8•24 or 8•24 GC; not an independent monitor colour-depth limit–
Supported signal modesMaker documents support 640 × 480 at 66.7 Hz, 35 kHz horizontal scan and a 30.24 MHz pixel clock. These describe the supported analogue signal, not a native fixed matrix. Factory-adjusted active image area is 235 × 176 mm with a dark surrounding border; colour depth depends on the video card.Supported 640 horizontal × 870 vertical analogue image at 75 Hz, 68.85 kHz horizontal scan and 80 dpi per maker documents; not a native fixed matrix. Owner guide specifies 57.2832 MHz dot clock, whereas Service Source gives 52 MHz. Factory active area 203.2 × 276.1 mm in owner guide (203 × 276 mm in Service Source).
Screen coating–Maker's high-contrast, antiglare, flat square screen with white phosphor
CalibrationMaker TIL8439 states luminance of 20 footlamberts at the brightness-control detent and 25 footlamberts fully open; no conversion to an unpublished cd/m² figure. A thin horizontal grille-support line in the lower third is normal for this Trinitron tube according to the owner and service guides.–
Connections
Video inputsDA-1513W3
USB-C chargingNoneNone
SpeakersNoNo
Other connectionsMacintosh DA-15 analogue RGB input with composite negative-going TTL sync and detachable video cable; this is not a PC VGA connector. Compatible Macintosh video circuitry or video card is required. No integrated speakers or audio ports.Physical 13W3 video socket, identified by EveryMac's exact-model cable specification and Low End Mac; owner's guide shows three coaxial and ten signal positions with separate negative-going TTL sync. Compatible Macintosh video card or an appropriate cable is required; the socket itself is not DA-15 or VGA. Three ADB sockets allow one computer uplink and two remaining peripheral connections; no integrated audio.
Design
Weight with stand15.5 kg16 kg
Tilt–Apple Universal Monitor Stand provides adjustable viewing angle but is optional, not included
Size without stand–Service Source gives 332 × 292 × 379 mm (height × width × depth); Apple support gives 13.1 × 11.5 × 14.9 inches. Optional stand dimensions not substituted.
Height adjustmentOwner guide supplies a height-adjustment bar that raises the front by one-quarter or one-half inch. Tilt-and-swivel Universal Monitor Stand is a separately sold accessory and is not counted as the included stand.–
Size with standService Source gives body height 281 mm, width 344 mm and depth 385 mm; current support archive instead gives 11 × 13.5 × 16 inches. Optional monitor stand dimensions are not substituted.–
Weight detailService Source gives 15.5 kg (34 lb), with TIL2165 also specifying 34 lb including video and power cables. Owner guide instead publishes 20 kg (44 lb) including cables; this maker conflict is retained without attributing it to an undocumented revision.Owner guide and Service Source publish 16 kg (35 lb); no conversion inferred
ControlsPower and manual degauss buttons on the rear; brightness with centre detent and contrast on the right side. Automatic degauss at power-up; maker specifies 20-minute warm-up to meet all specifications.Rear power switch; right-side brightness with centre detent and contrast controls. Maker specifies 20-minute warm-up to meet all specifications.
Power and support
Power useCurrent support, TIL2165 and owner guide give 160 W maximum; Service Source instead lists 90 W without the same maximum qualificationMaker 75 W maximum
Power supplyCurrent support and Service Source specify 85–270 V AC, 47–63 Hz. Owner guide gives 90–270 V AC, 47–63 Hz; TIL2165 instead gives 85–270 V AC, 50–60 Hz. These are mains ratings, not display refresh.Domestic Service Source and owner guide specify self-configuring 90–270 V AC, 47–63 Hz; these are mains ratings, not display refresh rates
SoftwareApple support dates introduction March 1987; March 2 1987 maker price list explicitly schedules M0401 availability in May, rather than immediate March retail. Actual first retail month remains unverified, so year 1987 is retained. AppleColor High-Resolution RGB for Macintosh is distinct from the earlier AppleColor RGB monitor for Apple IIgs; no hardware or release figures are borrowed from that display. No inferred direct successor.Intended for compatible Macintosh video hardware. Service Source explicitly covers the domestic version; international Series B repair documentation is separate, so regional hardware is not silently combined. Apple support and contemporary TIL date introduction March 1989; April 1989 Mini'app'les launch coverage explicitly says Portrait Display M0404 available in May 1989. Actual first retail month remains unconfirmed, so year 1989 is retained. Optional stand, unpublished brightness and unknown direct successor are not inferred.
