Abacus24-7 Apple Mini DVI Male to HDMI Female Video Adapter:by;

Use this cable adapter to connect your Mac with a Mini-DVI video output port to an external monitor, TV, projector or other display device with HDMI input. Plug the Mini-DVI end into your Mac, and connect the HDMI end to an HDMI (male to male) cable, then plug the cable into your HDMI input input jack. Compatible models:12-inch PowerBook G4, Intel-based iMac, the MacBook Intel-based laptop, the Intel-based Xserve, and the 2009 Mac Mini.
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 Mac to the monitor. It will need to be used with an HDMI cable (sold separately).
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.
