Apple Mini DisplayPort to DVI Adapter | White | MB570Z/B
Use this Mini DisplayPort to DVI Adapter to connect an advanced digital monitor, such as the 20- or 23-inch Apple Cinema Display, that includes a DVI connector, to your Mac computer.
Every Mac with a Mini DisplayPort allows you to connect an external display or projector using an adapter. You can use an external display as your main workspace or extend your desktop, or you can work in mirrored mode with a projector so you can view what your audience sees.
Review the documentation or check with the manufacturer of your monitor to make sure you're choosing the right adapter.
Compatible with Mac computers with Mini DisplayPort and Thunderbolt ports.
