Sharing Keyboards and Monitors Between Macs and PCs

For tips on sharing a single keyboard and monitor between Mac and PC, see our special report by Henry Norr.

Connecting Apple monitors to PCs

There are a variety of Apple monitor interfaces that need converter boxes or adapters in order to be used on PCs, and even on some Macs.

For instance, older Apple flat panel LCD displays used an all-digital Apple Desktop Connector (ADC) to connect the video signal and USB from Mac to display. Converter boxes let you connect Apple ADC displays to PCs that have video cards with DVI ports, and to Macs that have only DVI graphics ports, such as older Power Mac G4's and Mac Minis. There are also converters that let you connect ADC or DVI monitors to a PC's analog VGA port.





Conversion boxes and adapters

Gefen offers a large selection of converter boxes and adapters for connecting various types of displays to various types of PC connectors. These include (but aren't limittedto):

  • ADC to DVI Adapters and Cables
  • ADC to VGA Adapter: Connects Apple's digita.ADC computers to analog VGA displays.
  • DVI to VGA Conversion Box

Connecting PC input devices to Macintosh

These products let you use PS/2 PC keyboards and mouse on a Macintosh. This usually lets you take advantage of some of specialty keyboards available for PCs, such as wireless keyboards. These devices are not sharing devices, but let you use one or more PC input devices for a single Mac. However, you can also use these devices in combination with a plain PC keyboard/mouse/VGA switch to share keyboards and monitors.

A USB note: Any PC USB (Universal Serial Bus) keyboard will work with modern Macs. Macs have had USB ports since the late 1990's

ADB note: Macs made before the first iMac used an ADB (Apple Desktop Bus) connector for keyboards and mice. ADB is not compatible with USB or PS/2 and requires an adapter.
