Use this cable adapter to connect your 12-inch PowerBook G4TM, Intel-based iMacTM, MacBookTM Intel-based laptop, Intel-based XserveTM, or 2009 Mac MiniTM to an external monitor with DVI-D input. Plug the Mini-DVI end into your MacTM, and connect the DVI-D connector to a DVI-D cable.
Helpful Notes: This device is intended to function more as an adapter than as a cable, meaning its short length WILL NOT reach from your MacTM to the monitor. It will need to be used with a DVI-D cable (sold separately).
The adapter MUST be used with a DVI-D cable. The specification for DVI-D does not support analog video signals, so this adapter will not work if used with a DVI-to-VGA cable, or with a DVI-I cable. Please check your monitor's input ports to be sure it has a DVI-D input before purchase.
In addition, this adapter works only with Mini-DVI ports, not with Micro-DVI or Mini Display Ports. To quickly check what port you have: this adapter has a U-shaped connector that will match the U-shape found on Mini-DVI ports.
Highest resolution supported: 1920x1200 @60Hz.
Please note that Mini-DVI adapters are only compatible with Apple® computers purchased prior to October 2008. Any Apple® computers purchased after October 2008 will require Mini DisplayPort cables.
