Apple's Mini DisplayPort adapters work with Mac models that have a Mini DisplayPort , Thunderbolt port , or Thunderbolt 2 port when using Mac OS X Leopard 10.5.6 or later:
These adapters don't work with the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter, which doesn't support Mini DisplayPort displays.
Apple Mini DisplayPort to DVI Adapter
The Apple Mini DisplayPort to DVI Adapter connects a Mac that has a Mini DisplayPort , Thunderbolt port , or Thunderbolt 2 port to a display that uses a single-link DVI cable.
This adapter supports display resolutions up to 1920 x 1200.

Apple Mini DisplayPort to Dual-Link DVI Adapter
The Apple Mini DisplayPort to Dual-Link DVI Adapter connects a Mac that has a Mini DisplayPort , Thunderbolt port , or Thunderbolt 2 port to a display that uses a dual-link DVI cable.
This adapter supports display resolutions up to 2560 x 1600. To use it with a dual-link DVI display such as the 30-inch Apple Cinema HD Display, connect the USB cable from the display to the USB-A port on the adapter, then connect the USB-A cable on the adapter to the USB-A port on your Mac.
Apple Mini DisplayPort to VGA Adapter
The Apple Mini DisplayPort to VGA Adapter connects a Mac that has a Mini DisplayPort , Thunderbolt port , or Thunderbolt 2 port to display that uses a VGA cable.
This adapter supports display resolutions up to 1920 x 1200. To achieve resolutions greater than 1600 x 1200, displays with high refresh rates might require that you lower the refresh rate.
Because the VGA connection is analog instead of digital, HDCP-encrypted content might not play back, or might play back at a lower resolution.

DVI cables that provide additional pins for an analog signal aren't compatible with the fully digital DVI port on either of the DVI adapters.

The Mini-DVI connector is used on certain Apple computers as a digital alternative to the Mini-VGA connector. Its size is between the full-sized DVI and the tiny Micro-DVI. It is found on the 12-inch PowerBook G4 (except the original 12-inch 867 MHz PowerBook G4, it used Mini-VGA), Intel-based iMac, the MacBook Intel-based laptop, the Intel-based Xserve, the 2009 Mac mini, and some late model eMacs.
In October 2008, Apple announced the company was phasing Mini-DVI out in favor of Mini DisplayPort.
Mini-DVI connectors on Apple hardware are capable of carrying DVI, VGA, or TV signals through the use of adapters, detected with EDID (Extended display identification data) via DDC. This connector is often used in place of a DVI connector in order to save physical space on devices. Mini-DVI does not support dual-link connections and hence cannot support resolutions higher than 1920×1200 @60 Hz.
Mini Dvi Adapter Mac
There are various types of Mini-DVI adapter:
- Apple Mini-DVI to VGA Adapter Apple part number M9320G/A (discontinued)
- Apple Mini-DVI to Video Adapter Apple part number M9319G/A, provided both S-Video and Composite video connectors (discontinued)
- Apple Mini-DVI to DVI Adapter (DVI-D) Apple part number M9321G/B (discontinued)
Mini Dvi Splitter For Mac
A non-OEM Mini-DVI to HDMI Adapter is also available on certain online stores such as eBay and Amazon, and from some retail stores, but not from Apple.
The physical connector is similar to Mini-VGA, but is differentiated by having four rows of pins arranged in two vertically stacked slots rather than the two rows of pins in the Mini-VGA.
Connecting to a DVI-I connector requires a Mini-DVI to DVI-D cable plus a DVI-D to DVI-I adapter.
Mini Dvi For Mac Computers
Criticisms[edit]
- Apple's Mini-DVI to DVI-D cable does not carry the analog signal coming from the mini-DVI port on the Apple computer. This means that it is not possible to use this cable with an inexpensive DVI-to-VGA adapter for VGA output; Apple's mini-DVI to VGA cable must be used instead. This could be avoided if Apple provided a mini-DVI to DVI-I cable. The purpose of DVI-I is to ensure universal compatibility.[1][2]
- The Apple mini-DVI to DVI-D cable's package shows a DVI-I figure instead of DVI-D and does not specify that it comes with only DVI-D.
Compatibility[edit]
As Mini-DVI is pin-compatible with DVI, it supports both DVI and VGA through adapters.
