Introducing the Apple DVI to ADC Adapter. Now you can connect any Apple flat-panel display featuring an Apple Display Connector (ADC) to a PowerBook G4 or Power Mac G4 computer with a Digital Visual Interface (DVI) port.
The combination of the new PowerBook G4 with a DVI port and the Apple DVI to ADC Adapter brings the pure-digital viewing experience of Apple’s professional-quality displays to PowerBook users. Now you can benefit from a larger viewing area when your PowerBook is at your office. For example, if you connect a 23-inch Apple Cinema HD Display with 1920-by-1200 resolution to your new PowerBook G4 with 1280-by-854 resolution, you’ll have a total workspace of more than 3.3 million pixels.
The Apple DVI to ADC Adapter is also a superb solution for Power Mac G4 users who need extra workspace of the highest visual quality. Use it to connect an additional ADC-equipped Apple flat-panel display to a Power Mac G4 computer with a DVI port, and you’ll have the ultimate digital desktop. Imagine how productive you can be with two Apple Cinema HD Displays delivering more than 4.6 million pixels in stunning digital clarity.
