Apple's video cables and adapters connect its computers to monitors, televisions and video recorders. For Macintosh models with a DB-15 monitor port Apple sold a standard video cable, an extension cable and an adapter for VGA monitors.[1] The Power Macintosh 6100, 7100 and 8100 have an HDI-45 monitor socket that needs an adapter for any monitor other than the AudioVision 14.[2] The AV models came with two short adapters between their S-video ports and RCA plugs.[3] Apple II monitors take a plain RCA video cable.[4] The video adapter cables for PowerBooks are on Apple PowerBook cables.

Monitor port and sense lines
[edit | edit source]The Macintosh monitor connector is a 15-pin D connector. Apple documents the same pin assignments for the Macintosh II Video Card, the Macintosh IIci's built-in video and the later display cards and built-in video.[10][11] Pins 4, 7 and 10 are the monitor sense lines SENSE0, SENSE1 and SENSE2. At startup the video circuitry reads them to find out which monitor is connected and sets its timing to suit.[11] The early Macintosh II Video Card did not have the sense lines.[10][12] Apple's articles on the Quadra and Centris call the same pins MON.ID1, MON.ID2 and MON.ID3.[13]
| Pin | Signal | Description | Pin | Signal | Description |
|---|---|---|---|---|---|
| 1 | RED.GND | Red ground | 9 | BLU.VID | Blue video |
| 2 | RED.VID | Red video | 10 | SENSE2 | Monitor sense line 2 |
| 3 | /CSYNC | Composite sync | 11 | C&VSYNC.GND | Ground for CSYNC and VSYNC |
| 4 | SENSE0 | Monitor sense line 0 | 12 | /VSYNC | Vertical sync |
| 5 | GRN.VID | Green video | 13 | BLU.GND | Blue ground |
| 6 | GRN.GND | Green ground | 14 | HSYNC.GND | HSYNC ground |
| 7 | SENSE1 | Monitor sense line 1 | 15 | /HSYNC | Horizontal sync |
| 8 | n.c. | Not connected | Shell | Chassis ground |
The table is Apple's Table S-3 from Technical Note HW 30, with the shell connection from Technical Note HW 8.[11][10] A slash before a signal name means the signal is active low.[10]
Original sense codes
[edit | edit source]In the original scheme the monitor or its cable connects sense pins to pin 11 (C&VSYNC.GND). A grounded line reads 0 and an open one reads 1. Three lines give seven monitor codes and a "no display connected" code.[11]
| Sense 2 (pin 10) | Sense 1 (pin 7) | Sense 0 (pin 4) | Monitor type | Frame rate (Hz) |
|---|---|---|---|---|
| 0 | 0 | 0 | RGB 21-inch | 75.08 |
| 0 | 0 | 1 | Full-page (15-inch monochrome) | 75.08 |
| 0 | 1 | 0 | RGB 12-inch | 60.15 |
| 0 | 1 | 1 | Two-page (21-inch monochrome) | 75.08 |
| 1 | 0 | 0 | NTSC monitor | 59.94, interlaced |
| 1 | 0 | 1 | RGB 15-inch | 75.08 |
| 1 | 1 | 0 | Hi-Res (12 to 14-inch) | 66.67 |
| 1 | 1 | 1 | No display connected; extended codes are read | – |
Apple's 1990 table for the Macintosh II Video Card assigns only three codes: 001 for the Portrait monitor, 011 for the Two-Page monitor and 110 for a 640 × 480 monitor. The others are reserved.[12] The Macintosh IIci's built-in video supports 001 and 110 only. With any other code, or with no monitor, the system software switches the built-in video off, which is what happens when the IIci's monitor is plugged into a NuBus video card instead.[12]
The Macintosh LC reads the lines differently because it grounds pin 7 inside the computer. Apple's rules for the LC are pin 4 grounded for a 640 × 480 monitor, pins 4 and 10 grounded for the 12-inch RGB display (512 × 384) and pin 10 grounded for a VGA monitor.[10]
Extended sense codes
[edit | edit source].png)
When all three lines read 1, later video hardware drives each sense line low in turn and reads the other two. Apple calls this the type-7 extended protocol. A monitor or cable sets its code by joining sense lines to each other with wires or diodes, not to ground.[11] The type-6 extension works the same way for monitors that ground pin 4 and join pins 7 and 10 with a wire or with a diode in either direction. Apple used it for the multiple-scan displays: the Multiple Scan 17 reports itself as a "Multiple Scan 16" and the Multiple Scan 20 as a "Multiple Scan 21".[11]
| Monitor type | Type | Sense 2 low: lines 1 and 0 | Sense 1 low: lines 2 and 0 | Sense 0 low: lines 2 and 1 |
|---|---|---|---|---|
| Hi-Res (12 to 14-inch) | 6 | 10 | 10 | 11 |
| Multiple Scan 14-inch | 6 | 00 | 00 | 11 |
| Multiple Scan 16-inch | 6 | 00 | 10 | 11 |
| Multiple Scan 21-inch | 6 | 10 | 00 | 11 |
| PAL encoder | 7 | 00 | 00 | 00 |
| NTSC encoder | 7 | 01 | 01 | 00 |
| VGA and Super VGA | 7 | 01 | 01 | 11 |
| RGB 16-inch | 7 | 10 | 11 | 01 |
| PAL monitor | 7 | 11 | 00 | 00 |
| RGB 19-inch | 7 | 11 | 10 | 10 |
Each pair is what the two named lines read while the third is held low; 0 means the line followed the one held low.[11] Technical Note HW 30 gives the frame rates as 59.94 Hz for VGA, 55.98 Hz for Super VGA, 74.55 Hz for the RGB 16-inch, 74.93 Hz for the RGB 19-inch and 50 Hz interlaced for PAL.[11]
The connections Apple published for making these codes in a cable or adapter are:
- VGA: join pins 7 and 10. The same cable works on the Macintosh LC, because the LC grounds pin 7 and so pulls pin 10 low.[10][13]
- 832 × 624 (RGB 16-inch): join pins 4 and 10. Do not connect them to ground as well, or the computer will detect an RGB 12-inch monitor.[11][14]
- 1152 × 870 (RGB 21-inch): join pins 4, 7 and 10 to pin 11.[14]
- 1024 × 768 (RGB 19-inch): join pins 4 and 7.[13][11]
- Monochrome NTSC from a Quadra or Centris: ground pins 4 and 7 to pin 11 and take the green video on pin 5 to the tip of an RCA plug, with the connector shell to the sleeve. A colour NTSC signal needs an RGB-to-NTSC converter.[13]
- A Macintosh II run without a monitor can be made to set up a 640 × 480 screen with a plug on the video port that grounds pin 4 and leaves pins 7 and 10 open.[15]
The PAL monitor and NTSC encoder codes need a diode as well as a wire; Apple's Figure 3 shows the connections.[11]
Standard Macintosh video cable
[edit | edit source]Apple sold the DB-15 to DB-15 monitor cable as the Apple Standard Macintosh Video Cable, 1.5 m long, order number M3922LL/A.[1] Apple moulded the part number into the connector housing of all its monitor cables.[16] Apple's pinout article lists two DB-15 to DB-15 cables. Cable 590-0161 served the High-Resolution Monochrome Monitor and the AppleColor High-Resolution RGB Monitor and has no sense lines. Cable 590-4161 carries the three sense lines and was specified for the same two monitors "and future monitors".[16] Apple's 1996 parts list gives 590-4161, 1.75 m long, for the Apple Color High-Resolution RGB Monitor.[5] For the Display Cards 4•8, 8•24 and 8•24 GC, Apple's support article names 590-0161 for the Apple High Resolution Monochrome Monitor and the AppleColor High-Resolution RGB Monitor.[17]
| Pin | 590-0161 | 590-4161 |
|---|---|---|
| 1 | Red video ground | Red video ground |
| 2 | Red video | Red video |
| 3 | Composite sync | Composite sync |
| 4 | Composite sync ground | Sense ID 1 |
| 5 | Green video | Green video |
| 6 | Green video ground | Green video ground |
| 7 | not connected | Sense ID 2 |
| 8 | not connected | not connected |
| 9 | Blue video | Blue video |
| 10 | not connected | Sense ID 3 |
| 11 | not connected | Composite sync ground |
| 12, 14, 15 | not connected | not connected |
| 13 | Blue video ground | Blue video ground |
| Shell | Shield ground | Shield ground |
Neither cable carries the separate sync signals on pins 12, 14 and 15.[16] Other monitors have their own video cables in Apple's parts lists, such as the 12-inch RGB display's CPU-to-monitor cable 590-0693 and the AudioVision 14's video cable 922-0388.[18][9]
Video extension cable
[edit | edit source]The Apple Standard Macintosh Video Extension Cable, order number M3923LL/A, is 6 feet long with a male DB-15 at one end and a female at the other. Apple listed it with the standard video cable in its 1996 cable range.[1]
Macintosh-to-VGA adapters
[edit | edit source]Apple sold the Apple Standard Macintosh-to-VGA Video Adapter, M3924LL/A, for connecting a VGA monitor to a Macintosh DB-15 port.[1] Apple's 1996 list of Macintosh models with built-in video that drive a VGA monitor includes the LC, LC II, LC III, LC 475 and LC 630, the Performa 400 to 600 series and 630 series, the IIvx and IIvi, the Centris and Quadra range, the Power Macintosh 5200 to 9500, the PowerBook 160, 165c, 180, 180c and 500 series, the PowerBook 190 with its video upgrade, and the PowerBook Duo 210 and 230 on a MiniDock or Duo Dock. On these the VGA resolution is 640 × 480, and the colour depth depends on the installed VRAM.[19] The Macintosh LC drives a VGA monitor in 16 colours as standard and in 256 colours with the 512K VRAM SIMM. Apple warns that some VGA monitors with low-impedance inputs do not work with it.[10]
| Macintosh DB-15 pin | VGA pin | Signal |
|---|---|---|
| 1 | 6 | Red ground |
| 2 | 1 | Red video |
| 5 | 2 | Green video |
| 6 | 7 | Green ground |
| 9 | 3 | Blue video |
| 13 | 8 | Blue ground |
| 15 | 13 | Horizontal sync |
| 12 | 14 | Vertical sync |
| 14 | 10 | Sync (HSYNC) ground |
| 7 and 10 | – | Joined together, not connected to the VGA plug |
The wiring is the same in Apple's Technical Note HW 8 for the LC and in its support articles for the LC and the Quadra and Centris.[10][20][13] The Quadra 700, 900 and 950 and the Duo Dock II switch off sync on green when the sense lines report a VGA monitor.[21]
Apple also supplied adapters in the other direction with displays whose own cables end in a VGA plug:
- The Apple Basic Color Monitor has a three-row 15-pin plug and an adapter to DB-15, service part 922-1104. Apple's parts list warns that a separate non-VGA version of the monitor works with Macintosh computers only.[22] A Macintosh senses the Basic Color Monitor as a VGA monitor.[23]
- The Apple Multiple Scan 1705 Display comes with its own video cable, 922-1877, and a Mac-to-VGA adapter, 922-1458. The adapter is for PC-compatible computers only: fit it to the PC's video card and plug the display's cable into it.[24][25]
- The Apple Studio Display of 1998 and 1999 has a VGA connector on its cable and came with a VGA-to-Mac adapter for computers and graphics cards with the two-row Macintosh connector.[26]
Apple's other video adapters are the HDI-45 to DB-15 adapter for the Power Macintosh 6100, 7100 and 8100, which Apple's description of the 8100/110 calls the Video Adapter Cable,[27] and the PowerBook video adapters described on Apple PowerBook cables.
Display adapters
[edit | edit source]Apple's documents use the name "display adapter" for three different items.
The Power Macintosh Display Adapter, M2681LL/A, is the HDI-45 to DB-15 adapter for the first Power Macintosh models. It is described below.[7]
Sense adapters let an older Macintosh or video card run a multiple-scan display above 640 × 480. Those computers and cards cannot reprogram their video for the multiple-scan sense codes, so without an adapter the display runs at 640 × 480 only. The adapter plugs onto the display's cable and gives the code of a fixed-frequency monitor, such as the 16-inch or 21-inch RGB display.[14][28] Apple's two published adapters pass every video and sync pin straight through. The 832 × 624 adapter joins pins 4 and 10 on its male DB-15 end, and the 1152 × 870 adapter joins pins 4, 7, 10 and 11.[14] The Macintosh II family, the PowerBooks, the Duo Dock and MiniDock, the LC, LC II and LC III, the Performa models other than the 475, 476 and 630 family, and the Display Cards 4•8, 8•24 and 8•24 GC need an adapter. The Power Macintosh, Centris and Quadra range, the LC 475, the Performa 475 and 476, the 630 family and the Macintosh Display Card 24AC do not. The Duo Dock does not need one under System 7.5.[28] With an adapter, the LC III, the Performa 450 to 467, the PowerBook 160, 165, 165c, 180 and 180c, a Duo on the Duo Dock or MiniDock, and the three display cards reach 832 × 624. The IIci, IIsi, IIvx, LC, LC II, Performa 400 to 430 and Performa 600 stay at 640 × 480 on their built-in video.[28] Apple named Enhanced Cable Technology, Griffin Technology and MacAdapt as makers of these adapters.[28] The Multiple Scan 17's parts list also includes a "Cable, Adapter, Multi Scan 17 to Mac II", 922-1125.[6]
The Mac/PC Display adapter, service part 922-0736, connects a multiple-scan display to a PC-compatible computer.[6] The Apple Multiple Scan 17 Display came with one and the Apple Multiple Scan 15 Display did not; the same adapter fits the Multiple Scan 15, and Apple sold it as a service part.[29] It is also in the parts list of the Apple Multiple Scan 20 Display.[30]
HDI-45 to DB-15 adapter
[edit | edit source].svg)
Every Power Macintosh 6100, 7100 and 8100 has an HDI-45 monitor socket for its built-in video. The 7100, the 8100 and the AV models also have a DB-15 monitor socket on a video card.[2] The HDI-45 carries video, sound, ADB and S-video input for the Apple AudioVision 14 Display.[3] Any other monitor needs the Power Macintosh Display Adapter, M2681LL/A, which has an HDI-45 plug at one end and a DB-15 monitor socket at the other.[3][7] Apple's 1995 support article says it came with every 6100 and was an option for the 6100AV, the 7100, the 8100 and the other AV models.[2] The 6100 Service Source lists it as included with the 6100AV as well, and the 7100 and 8100 Service Sources call it optional.[31][32][33]
The HDI-45 port's frame buffer is 640K of main memory; there is no VRAM behind it. It drives no monitor above 832 × 624, so a 19, 20 or 21-inch monitor at its higher resolutions needs a third-party video card or the AV card.[2]
| Monitor | Resolution | Colour depth (bits) |
|---|---|---|
| 12-inch RGB | 512 × 384 | 16 |
| 14-inch RGB | 640 × 480 | 16 |
| 15-inch portrait | 640 × 870 | 8 |
| 15-inch, 17-inch and 20-inch Multiple Scan | 640 × 480 | 16 |
| 15-inch, 17-inch and 20-inch Multiple Scan | 832 × 624 | 8 |
| 16-inch RGB | 832 × 624 | 8 |
| VGA | 640 × 480 | 8 |
From Apple's support article of July 1995.[2] A VGA monitor still needs a Macintosh-to-VGA adapter at the DB-15 end.[19]

| 15 | Reserved | 30 | Reserved | 45 | Blue video output (75 Ω) |
The table is Apple's Table 3-9.[3] Apple's other Power Macintosh pinout article gives the same assignments.[34]
AudioVision adapter cable
[edit | edit source]The adapter for the other direction connects an AudioVision 14 Display to a Macintosh that has no HDI-45 socket. The AudioVision adapter cable kit, M1243LL/A, ends in separate plugs for the monitor port, sound input, sound output and ADB, and the AudioVision cable plugs into its high-density socket until it clicks.[8] Computers without the high-density socket also need the AudioVision software installed.[8] The service part for the adapter cable is 922-0419.[9] Apple's 7100 user's guide recommends connecting an AudioVision monitor to the 7100's second monitor port through the adapter kit when it is used for video digitising, because the results are better than on the HDI-45 port.[35]
Portrait and Two-Page monitor cables
[edit | edit source]The Apple Portrait Display and Apple Two-Page Monochrome Monitor do not use a DB-15 at the monitor end. Apple's cable for connecting either of them to a display card or to the Macintosh IIci is 590-0615, which has a DB-15 at the computer end and a 13-pin mixed-contact D-connector at the monitor.[17] Apple's pinout article and its parts lists describe the monitor end as a DB-25 and give 590-0574 as a DB-25 to DB-25 cable for the same monitors.[16][36] An owner repairing a Portrait Display describes its connector as a 13W3.[37]
Composite video cable
[edit | edit source]The Apple II family connects to its composite monitors with a cable that has an RCA phono plug at each end. The Apple Monitor II manual says the video cable comes with the computer and that either end can go into the monitor.[4] The Apple Monitor IIc came with its own video cable.[38] So did the AppleColor Composite Monitor, whose guide notes that both ends of the cable are the same.[39]
Among Macintosh models, the Quadra 660AV, Quadra 840AV and Power Macintosh 7500, 7600 and 8500 have separate composite and S-video connectors. The Power Macintosh 6100AV, 7100AV and 8100AV have S-video connectors only and need adapters for composite video.[40] The built-in video of the Macintosh IIci, IIsi and LC cannot produce an NTSC-compatible signal.[41] The Apple Presentation System, a scan converter for showing a Macintosh screen on a television, came with a composite video cable and an S-video cable as well as a DB-15 video input cable.[42]
Apple knew of no length limit for composite or S-video cables. Its advice was to keep runs under about 50 feet, with high-quality cable working at 100 feet or more, and to use a video distribution amplifier for long runs.[43] Line loss on long cables shows as ghosting, smearing or faint lines across the picture, and does not damage the equipment.[44]
S-video cable
[edit | edit source]The Quadra 660AV, the Quadra 840AV and the Power Macintosh AV card have 7-pin S-video connectors. A standard 4-pin S-video cable fits them and works, because pins 5, 6 and 7 are extras that Apple reserved for future products.[45]
| Pin | Standard 4-pin | Apple 7-pin input | Apple 7-pin output (Power Macintosh AV card) |
|---|---|---|---|
| 1 | Analog ground (signal) | Analog ground | Analog ground |
| 2 | Analog ground (power) | Analog ground | Analog ground |
| 3 | Luminance (Y) | Luminance (Y) | Luminance (Y) |
| 4 | Chroma (C) | Chroma (C) | Chroma (C) |
| 5 | – | I²C clock | Composite video |
| 6 | – | +12 V | No connection |
| 7 | – | I²C data | No connection |
From Apple's support articles and the Power Macintosh developer note.[45][3] On the Power Macintosh AV card the +12 V on the input connector is limited to 250 mA and fused at 1.1 A.[3] Apple rated the camera and S-video input of the Centris 660AV and Quadra 840AV at +12 V, 500 mA.[46] Apple warns that the Centris 660AV and Quadra 840AV will not start if a serial or ADB cable is plugged into an S-video port.[46] The 7100 user's guide warns that the S-video plug looks like the printer, modem, mouse and keyboard plugs and is not interchangeable with them.[35]
The Apple Presentation System was supplied with an S-video cable.[42] On the Power Macintosh AV models, use the AV card's S-video input; Apple does not support the S-video input on the AudioVision 14 Display with those computers or with the Quadra 660AV and 840AV.[47]
S-video to composite adapters
[edit | edit source].png)
The Power Macintosh 6100/60AV, 7100/66AV and 8100/80AV came with two adapter cables between the AV card's S-video connectors and RCA connectors, so that a television, video camera, videodisc player or video recorder with RCA plugs can be connected.[3] The input adapter connects the signal pin of an RCA socket to pin 3, the luminance input, of the video input connector. The output adapter takes pin 5, the composite video output, to the signal pin of an RCA plug.[3] Each adapter is marked with an IN or OUT icon on the flat part of the connector. Fit the IN adapter to the input port and the OUT adapter to the output port, with the curved side of the plug to the right.[35][48]
The two adapters look the same apart from the markings. Fitted to the output port, the IN adapter gives a greyscale picture on the television.[48] The IN adapter is wired to pin 3, and on the output connector pin 3 carries luminance only; the composite signal is on pin 5.[3]
A Quadra 660AV or 840AV upgraded to a Power Macintosh AV loses its RCA composite ports. Composite video then goes through these adapters on the AV card's S-video ports.[49]
Faults and things that are not faults
[edit | edit source]| Symptom | Cause | Action |
|---|---|---|
| Multiple-scan display stuck at 640 × 480 on an older Macintosh | The computer or card cannot switch to the multiple-scan resolutions | Fit a sense adapter, or use a Display Card 24AC[14] |
| Multiple Scan 15 shows a picture split into four on a IIvx, LC II, Performa 400 to 430 or Performa 600 | These computers supply composite sync and the display needs separate sync | Fit an adapter that generates separate horizontal and vertical sync[50] |
| Multiple Scan 1705 power light amber, no picture | The PC adapter has been fitted to an old Macintosh monitor cable | Use the cable that came with the display and no adapter; the adapter is for PCs only[25] |
| Third-party monitor has a green tint | The monitor uses the sync on green and the separate sync signals together | Use a cable or adapter that does not pass the separate sync lines[21] |
| Third-party monitor that needs sync on green shows no picture | Many models have no sync on green, among them the LC III, LC 475, 550 and 575, the Quadra 605, 660AV and 840AV, the 630 family, all portables, the Duo Dock and every Power Macintosh | Fit a third-party adapter that adds sync on green[21] |
| Apple Basic Color Monitor picture is poor with an LCD projection panel in the chain | The panel's Macintosh cable makes the computer send Apple RGB timing | Use the panel's VGA cable and the monitor's VGA adapter[23] |
| Multiple Scan 20 cable will not seat on a Power Macintosh 7100 or 8100 | The early connector is too wide for the opening; a thinner cable went into distribution in June 1994 | Push it in as far as it goes and turn the thumbscrews about one turn, without stripping them[51] |
| Computer detects a 12-inch RGB monitor when a 16-inch was intended | The joined sense pins 4 and 10 are also grounded | Join pins 4 and 10 only[11] |
| Television picture from a Power Macintosh AV is greyscale | The IN adapter is on the output port | Swap the adapters[48] |
| AV Macintosh will not start | A serial or ADB cable is in an S-video port | Move the cable to the correct port[46] |
| Power Macintosh 8500 seems to hang in the Color Picker with only an S-video cable attached | The S-video cable creates a second, unseen monitor and the Color Picker dialog opens on it | Press Return to dismiss the dialog; set the visible monitor to a greater colour depth than the other[52] |
