TOPIC

    I purchased two AppleVision Monitors and am trying to set them up, but my computer only has one ADB port on the back. I tried connecting the ADB cable from the first monitor to the side of the second monitor, but that did not work. Then I tried using a third party ADB splitter cable and the second monitor came up in 640x480 only. How do I set them up correctly?

    Note: The ColorSync 20-inch Display was formerly named the AppleVision 850 Display. The "AV" suffix is appended to the monitor name as appropriate.

DISCUSSION

    To set up two AppleVision displays with a computer that has a single ADB port, be sure to use the recommended Apple shielded connector cable (ADB splitter cable), part number M5556LL/A. This is the only officially supported method of connecting two AppleVision Displays to a single Macintosh ADB port. Setup instructions are in the User Manual for the display.

    When some third-party ADB splitter cables are used, AppleVision software may be unable to recognize one or both monitors as AppleVision displays. As a result, the screen resolution of the unrecognized monitor(s) will revert to 640x480, and the AppleVision control strip and control panel will not allow you to select any other resolution besides 640x480.

    When you open the AppleVision Setup control panel, a dialog window appears on AppleVision Display #1. This is the display designated through the Monitors control panel as the startup display.

    You are also able to adjust the bit depth and resolutions for both displays separately through the control strip at the bottom of the display. The displays appears as two separate sections with the name of the display at the top of these sections.

    Example: AppleVision 1710/AV Display 1 and AppleVision 1710/AV Display 2

    If two AppleVision 1710AV Displays are used you will only have microphone and speaker capabilities through one of these displays by connecting the sound and microphone connections to your Macintosh computer. There may be third-party solutions allowing you to connect two connections to both ports on the back of the computer.

    Notes:
    • Some NuBus or PCI video cards may only support one resolution; 640x480, when using any Multiple Scan Display.
    • A limit of two AppleVision displays are supported simultaneously on one CPU.
    • It is recomended you install the latest version of the Apple Display Software to prevent errors when the software loads. (Apple Display Software supercedes and replaces AppleVision software as of version 1.5.3 of AppleVision software.)
