Display Adapters The Apple Multiple Scan 20 Display has several resolutions. Macintosh computers designed before the introduction of Apple Multiple Scan 20 Display will only recognize the display as a 14-in color display without an adapter. The adapters, available through Apple Resellers and third party companies, contain a sense code that tells the Macintosh that the display is fixed frequency 16-in. or 21-in. display. Without the adapter, the display will be fixed at a 640x480 resolution. Display adapters are available from several third-pary companies such as Enhanced Cable Technology, Griffin Technology, and MacAdapt. This article provides information about a non-Apple product.
