The Mini-DVI connector is used on Apple computers as a digital alternative to the Mini-VGA connector. It is found on the 12" PowerBook G4, Intel-based iMac, the MacBook Intel-based laptop, and the Intel-based Xserve. 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. It needs a Mini-DVI Adapter to connect to another monitor.
There are various types of Mini-DVI Adapter:
- Apple Mini-DVI to VGA Adapter
- Apple Mini-DVI to Video Adapter
- Apple Mini-DVI to DVI Adapter (DVI-D)
- Apple Mini-DVI to VGA Display Adapter
- Apple Mini-DVI to ADC Display Adapter
They are all sold in Apple Stores.
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.
There have been criticisms of Apple's introduction of Mini-DVI. It has introduced a completely new connector despite the existence of DVI and VGA. On Apple's current line of laptops, the smaller Macbooks utilize Mini-DVI while the Macbook Pros have DVI and are sold with a converter for DVI to VGA.
