TOPIC



    This article provides information on which Apple video cards and computers need display adapters to get greater resolution from the Apple Multiple Scan 17 Display.

DISCUSSION



    The Apple Multiple Scan 17 Display has several resolutions. Macintosh computers designed before the introduction of Apple Multiple Scan 17 Display will only recognize the display as a 14-in color display without an adapter. Display adapters, available through Apple resellers and the third-party companies, contain a sense code that tricks the Macintosh into believing that the display is fixed frequency 16-in. or 19-in. display. Without the adapter, the display will be fixed at a 640x480 resolution.
