A PowerMac 8100 and Apple Professional XDR Show.
HDMI is the de facto normal for connecting a monitor to a Mac and has been for a few years, however there are a lot of older Macs on the market that may’t be simply linked to that fashionable connector. Here is easy methods to join your classic Mac to your new monitor.
For longer than it hasn’t, Apple has gone its personal manner on monitor connections. There’s been Apple’s model of DA-15, HDI-45, ADC, mini DisplayPort, and some others. The remainder of the trade, bigger for many of Apple’s historical past, determined VGA was the best way to go, then DVI, and DisplayPort.
Thankfully, it is all principally settled on HDMI. Here is easy methods to join your classic gear to fashionable screens, and what it is advisable do it.
The eighties — Apple RGB
Through the Mac II period, Macs and official Apple video playing cards featured a proprietary Apple video connector generally known as Apple RGB via NuBus enlargement playing cards, however Apple RGB to VGA adapters have been accessible.
In reality, these adapters are nonetheless accessible new from firms corresponding to Monoprice ($10) or PTC.
One finish of the adapter has normal PC VGA, the opposite finish has Apple’s proprietary Apple video connector. These adapters have a financial institution of DIP switches for configuration, as a result of the Apple connector had a distinct sync mechanism than VGA did on the time.
Apple’s Macintosh IIci, circa 1989.
Apple used the Apple Video Connector up via its beige G3 line. It was finally changed by PCI video playing cards – however extra on that in a bit of bit. Within the interim, it had a distinct customized connector for video and knowledge.
Most early Apple Video Connectors on Macs have been based mostly on the DA-15 normal (generally mistaken for DB-15) – apart from the Energy Macintosh 9600. That featured a DB13W3 connector which added three further high-frequency pins.
DB13W3 was standard on Solar Microsystems and Silicon Graphics workstation computer systems of the Nineteen Nineties. Each DA-15 and DB13W3 are a part of the D-Subminature or just “D-sub” connector household — and are thankfully simply adaptable to VGA.

The nineties — HDI-45
Apple referred to HDI-45 as “AudioVision” and created its personal shows. This consists of the Apple 14-inch and 17-inch AudioVision shows which may join on to the HDI-45 connector.
Apple launched the Energy Mac 6100, 7100, and 8100 all on the similar time. All three fashions had the identical HDI-45 connector on the again of the machines.

Like fashionable HDMI, this connector may carry audio, sync, luminance, coloration, and picture alerts.

Apple additionally made a wide range of adapter cables to transform HDI-45 to Apple’s personal proprietary analog video sign for Macintosh video playing cards.
For a really temporary time, Apple bought its personal HDI-45 to Apple video connector known as the Apple HDI-45 Energy Mac Show Adapter. See this Apple dialogue thread for more information.
PowerBook Duos
In 1995 Apple launched the PowerBook Duo 2300c. Like its earlier cousins from 1992 (PowerBook Duo 210 and 230), the 2300c featured a large proprietary 156-pin Processor-Direct connector on the rear. There have been 4 different Duo fashions as properly.
The 2300c shared the 210’s and 230’s slim type issue, and from the outside, all Duo fashions appeared practically equivalent.
Apple bought a full-sized DuoDock and Duo MiniDock which transformed the proprietary connector’s alerts to frequent ports – together with an Apple Video Connector port on the rear of the docks.
The three DuoDock fashions (launched in 1992, 1994, and 1995) allowed all PowerBook Duo fashions to make use of quite a few ports at a desk that have been absent from the laptops themselves. SCSI and proprietary 3.5-inch floppy drive (HDI-20) connectors have been additionally offered.
By shifting all frequent exterior ports to the dock, Apple was in a position to shrink the scale of the PowerBook Duo fashions, which for his or her time have been thought of exceptionally small.
The DuoDocks allowed a closed PowerBook Duo to be inserted into the entrance slot on the dock, at which level an inner motor would pull the pocket book inside and lock it in place. An influence button on the dock’s rear panel allowed the person to energy on the unit as if it was a desktop laptop.
EBay is your most suitable option for PowerBook Duo equipment. There are no low-cost adapters remaining.
The early twenty first century — ADC, mini DVI, AGP, and DisplayPort
PCI arrived alongside the best way, beginning with the Energy Macintosh 9500, and was rapidly adopted up with the 7200, 7500, and 8500. This opened issues up. However, solely a bit of, as the flavour of PCI Apple used was not totally compliant with PC PCI playing cards.
Apple did use Accelerated Graphics Port (AGP) playing cards beginning with most fashions of the unique G4 tower in 1999, however even these playing cards had some variations from normal.
AGP is a superset of PCI and has a number of benefits over PCI. Probably the most notable distinction are a devoted bus and direct reminiscence entry. Lots of Apple’s late ’90s Macs shipped with AGP slots.
PCI playing cards for PowerPC-based Macs additionally needed to have their very own Mac-specific ROMs which supported Open Firmware — so many video playing cards for PCs would not work in Macs.
On the similar time, within the early 2000’s together with the discharge of the primary model of Mac OS X (which is now macOS), Apple created its personal show normal known as Apple Show Connector (ADC).
ADC was a single connection normal for its new 20-inch, 22-inch, and 23-inch Cinema Shows. These shows had a single unified 30-pin connector plus 5 pins for RGB and sync. The ADC cable carried each energy and show alerts.
This meant no exterior energy wire was wanted for the show. Nonetheless, ADC shows nonetheless required an exterior energy brick which was included.
An ADC Mac to a DVI show adapter has gotten costly lately. Anticipate to spend $200 or so on eBay. Your finest wager is VGA to HDMI, which we’ll focus on in a short while.
Round this similar time, PCs have been switching to the DVI normal, and plenty of Mac customers balked at having to make use of proprietary ADC {hardware}. In response, Apple launched the DVI to ADC Adapter.
Apple’s ADC to DVI Adapter.
Quite unwieldy, this adapter included yet one more energy adapter, cables, and the flexibility to transform from normal DVI to Apple’s ADC shows. The ADC normal was disliked by customers, and Apple rapidly deserted it.
Apple’s later 30-inch and 23-inch Cinema HD Shows dropped the ADC connector, changing it with a regular DVI or Twin-Hyperlink DVI.
In reality, Apple made two adapters, one for entering into both route. The DVI to ADC adapter was rather more complicated because it required proprietary conversion circuitry to drive Apple’s ADC shows.
The 30-inch show used a particular Twin-Hyperlink DVI connection and requires a particular DVI adapter to work with fashionable Macs.
In 2006 DisplayPort was launched. DisplayPort is a contemporary digital show normal supposed to exchange DVI, however it has principally been eclipsed by HDMI in sensible utilization. That stated, many fashionable shows nonetheless characteristic DisplayPort connectors.
Two years later Apple launched mini DisplayPort which complied with the DisplayPort normal, however which featured a a lot smaller connector designed to suit on MacBooks of the period. These ports later discovered their manner into Apple desktop Macs.
If it is advisable use an older Mac with mini DisplayPort and a more recent Twin-Hyperlink DVI or Apple’s 30-inch Cinema Show, this adapter will be just right for you. If you wish to use a mini DisplayPort-based Mac with a smaller generic show, single-link mini DisplayPort adapters can be found.

To make issues much more complicated, on the similar time Apple launched a brand new line of PowerBook Macs which used mini DVI – and which required a mini DVI to DVI adapter. Apple bought this adapter and a mini DVI to ADC adapter for PowerBooks.

In brief, some early 2000-era Macs shipped with ADC-based Apple or ATI video playing cards, and a few shipped with DVI. Relying on which connector your Mac has, you will must find the suitable adapter.
Mac mini
When Apple launched newer Mac minis utilizing the Core Duo 2 and later Intel processors, it included DVI on all unique mini fashions.
DisplayPort connectors by no means actually caught on with Macs besides on Mac minis and a few MacBooks, so most Mac customers needn’t fear about it. Nonetheless, it is also pretty simple to transform most Mac DisplayPort connections to HDMI.
All Thunderbolt 1 and a pair of Macs featured mini DisplayPort over Thunderbolt, however these ports have been rapidly changed with DisplayPort over USB-C connectors.
It is completely potential to drive two fashionable shows with these machines — if their video playing cards assist your shows’ resolutions.
Quickly after the introduction of those Macs, numerous third-party distributors corresponding to Belkin and others started delivery assorted adapters to transform from one show normal to a different. Apple has a technote (111808) on all its Mini DisplayPort adapters and a technote on figuring out Mac ports typically.

Thunderbolt and HDMI
In 2011, Apple launched a brand new show known as Apple Thunderbolt Show. This 27-inch, 60Hz digital flat-panel show incorporates a single cable with Thunderbolt and one MagSafe cable for MacBooks.
Carrying video over Thunderbolt vastly improved show efficiency and response time. It additionally allowed extra pixels to be packed right into a show than ever earlier than.
Across the similar time, or a bit of earlier, Apple started offering HDMI ports constructed into Macs, since many show firms had already shifted to HDMI as a PC normal.
HDMI is simple, small, carries each video and audio, and is a ubiquitous normal. HDMI may also be used to plug your HDMI-enabled Mac into some fashionable HDMI TVs – if resolutions will be matched on each.
Maybe the simplest video conversion of all for classic Macs is from DVI on to HDMI.
Many distributors make direct DVI to HDMI cables, together with one from Amazon ($9) that works in each instructions.
If you will get your previous Mac’s video sign transformed to DVI, there is a good probability you may convert it to HDMI too utilizing one in every of these cables.
What about VGA?
Video Graphics Array (VGA) is an previous normal that launched on IBM PS/2 from the late ’80s which makes use of a DE-15 connector. Earlier than DVI, VGA caught on within the PC world and have become the de-facto video normal for PCs.
For a lot of the ’90s, Apple shipped round a dozen Apple show fashions that used both the Apple DE-15 Video Connector or the HDI-45 connector.
These embrace the later 17-inch and 21-inch CRT Studio Shows and earlier than these, the Apple “Traditional” Monitor Sequence.
The Traditional monitor collection included the smaller AudioVision shows, 12-inch monochrome and coloration shows, Performa shows, and the Apple Fundamental Colour Monitor.
It wasn’t till the 15-inch “Studio Show (Blueberry) (LCD)” in 1999 that Apple shipped a show that had a regular DE-15 VGA connector on it.
Simply earlier than the flip of the century, Apple shipped iBook laptop computer fashions based mostly on PowerPC G3 processors which included a proprietary 14-pin Mini-VGA connector.
The Mini-VGA connector was additionally accessible on some Apple eMac fashions, and the 12-inch PowerBook G4 laptop computer.
However surprisingly, Apple does nonetheless promote a USB-C VGA Multiport Adapter ($69), which might output VGA, features a USB port for attaching gadgets, and a pass-through USB-C charging port.
This adapter lets you join a USB-C or Thunderbolt 3/USB-C enabled Mac, iPad, or iPhone to a VGA show.
For any normal DVI-equipped Mac, Apple bought an Apple DVI to VGA Adapter (M8754G/A). This adapter matches onto a DVI video connector on a Mac and has a regular VGA port on the opposite aspect.
For many older DVI-enabled Macs, that is the simplest manner to hook up with a VGA show at present — however the Apple adapter could also be a bit of tough to seek out because it was discontinued way back. Third-party equivalents are simple to seek out and are cheap.
Additionally see our earlier article for a deep dive into DVI and VGA requirements, and their numerous related connectors and cables.
Trendy conversion and upscaling
Normally, any classic Mac that features an Apple proprietary video show connector can be utilized with any VGA show that helps one of many video card’s resolutions.
To take action, discover an Apple to VGA adapter that sits between the Apple video output connector and the VGA show’s cable. Low cost VGA shows abound within the second-hand market and in thrift shops.
The simplest option to get a very previous Mac working with a brand new show is to transform the supply output sign to VGA after which convert the VGA/DVI to HDMI.
When you’re utilizing an XDR show you then’ll wish to go from the supply to Thunderbolt immediately or to HDMI after which to Thunderbolt.
There are, the truth is, lots of cheap direct VGA to Thunderbolt adapters from firms corresponding to BENFEI.
However since VGA has such low decision in comparison with fashionable shows, you might discover direct VGA to 6K a bit unusable. A greater manner could be to transform the VGA output to HDMI, after which convert that to 6K or 4K.
Or you should use a {hardware} upscaler which might take a low-resolution video sign and (in {hardware}) resample it as much as a better decision. These converters can present a a lot clearer picture on the output aspect from a comparatively lower-res VGA enter.
For contemporary third-party shows, most fashionable screens have both HDMI, DisplayPort, or each built-in. With these shows, if you will get the unique Apple video sign or a DVI/VGA sign transformed to HDMi, you are in.
For older ADC-based Mac video playing cards, you will must convert the ADC video sign to DVI or HDMI immediately.
With such all kinds of recent and classic show adapters round, it is possible you may convert out of your previous Mac to a contemporary show.
