In-Depth Information
If the external display uses a DVI-I port, it probably means you have a DVI-I cable, and that cable won't fit
either of the adapters' DVI-D connectors. In this case, the adapter on its own won't cut it. To solve the problem,
you either need to buy a DVD-D cable or you need to hunt down a DVI-D to DVI-I adapter so you can use your
DVI-I cable.

Use the Apple Mini DisplayPort to Dual-Link DVI Adapter to connect your Mac's Mini DisplayPort to an external
display's dual-link DVI port.
A dual-link DVI connector plugs into (and works with) a single-link DVI port. Unfortunately, the reverse isn't true;
that is, you can't plug a single-link DVI connector into a dual-link DVI port. Note, too, that a DVI-D connector can
plug into a DVI-I port, but a DVI-I connector won't fit into a DVI-D port.
VGA connections
All CRT monitors and many LCD monitors and projectors come with a VGA connector, shown in Figure 1.7.
To connect MacBook Air to an external display that offers only a VGA connector, use the Mini DisplayPort to
VGA adapter, shown in Figure 1.8.

VGA connectors are standard on CRT and common on LCD monitors.
