Overview
Released1987July 1994
Display
Screen size12.8″13.3″
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 flat-square shadow-mask CRT with 13.3-inch viewable image and 0.28 mm dot pitch; no fixed native pixel matrix. Apple Facts notes two designs sold worldwide.)
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.Apple's archived support sheet lists 640 × 480 at 60 or 66.7 Hz, 800 × 600 at 60 or 72 Hz, 832 × 624 at 75 Hz and 1024 × 768 at 70 Hz. Service Source restricts 1024 × 768 to PC-compatible computers using a Mac/PC adaptor; Apple Facts October 1995 instead lists that Windows mode at 60 Hz. Supported modes depend on computer and regional design; these are CRT signal modes, not a native matrix or native refresh rate.
Screen coating–Service Source describes a polished surface treatment; archived TIL 15754 describes antistatic and antiglare treatment for European models only
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luminance of 20 footlamberts at the brightness-control detent and 25 footlamberts fully open; no conversion to an unpublished cd/m² figure.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-15DA-15
USB-C chargingNoneNone
SpeakersNoYes
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.Captive Macintosh 15-pin DA-15 analogue RGB video connector; a Mac/PC adaptor is needed for VGA computers. The archived TIL pinout identifies the Macintosh connector, rather than a VGA DE-15 socket.
Audio out–One audio input and one headphone/speaker pass-through port in Service Source; archived TIL describes a front-panel headphone jack
Speaker detail–Stereo speakers and headphone jack confirmed by Apple Facts October 1995 and archived TIL 15754; EveryMac's no-audio entry conflicts with those maker sources
Design
Stand adjusts–Tilt, swivel
Weight with stand15.5 kg14 kg
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.Apple's current archive lists 16.7 × 15.9 × 17.8 inches (height × width × depth). Apple Facts October 1995 also publishes 42.4 × 40.5 × 45.2 cm and warns that two worldwide designs have different dimensions and weight. Archived TIL 15754 instead gives 375 × 365 × 380 mm including base; the difference is retained.
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.Apple Facts and Service Source publish 14 kg (31 lb); Apple Facts warns dimensions and weight may vary between the two worldwide designs
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.Front-panel power, brightness and contrast; geometry shift and size, zoom, reset and recall controls. Automatic degauss on power-up.
Power and support
Power useCurrent support, TIL2165 and owner guide give 160 W maximum; Service Source instead lists 90 W without the same maximum qualificationMaximum 90 W; archived TIL specifies less than 30 W in Energy Saver mode
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.Service Source specifies 90–134 or 198–260 V AC, 47–63 Hz; these are mains ratings
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.System 7.1 or later. Some older Macintosh models require an adaptor for modes beyond 640 × 480. Apple lists introduction as July 1994; TidBITS reported shipping by 25 July 1994, so month precision is retained. Brightness and contrast ratio are unpublished.
