PPT98: Some Views in Grayscale on PowerBook External Monitor (186733)


The information in this article applies to:

  • Microsoft PowerPoint 98 Macintosh Edition
This article was previously published under Q186733

SYMPTOMS

If you attach a color external monitor to a grayscale PowerBook (such as the PowerBook 5300c) and then run PowerPoint 98, some views appear in grayscale on the external monitor. These include Slide Sorter and Slide Show views. Other views, such as the Slide and Notes Page views, appear in color on the external monitor.

This symptom occurs if Video Mirroring is turned on.

RESOLUTION

To successfully use Video Mirroring on this type of configuration, you can do the following.

NOTE: These steps assume you are running Macintosh OS 8 or later. If you are running an earlier version of the Macintosh operating system, the names of some of the buttons and control panels may be slightly different.
  1. Temporarily turn off Video Mirroring. To do this, follow these steps:
    1. On the Apple menu, point to Control Panels and then click PowerBook Display.
    2. Click the Off button.
    3. Close the PowerBook Display control panel.
  2. Move the menu bar to the external monitor. To do this, follow these steps:
    1. On the Apple menu, point to Control Panels and then click Monitors and Sound.
    2. Click the Arrange button.
    3. Drag the menu bar from the icon representing the built-in monitor to the icon representing the external monitor.
    4. Close the Monitors and Sound control panel.

      Now the menu bar appears on the external (color) monitor rather than the built-in (grayscale) monitor.
  3. Turn Video Mirroring back on. To do this, follow these steps:
    1. On the Apple menu, point to Control Panels and then click PowerBook Display.
    2. Click the On button.
    3. Close the PowerBook Display control panel.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

Video Mirroring is a technology that allows one display adapter to echo the content of another display adapter. In order for your Macintosh to support Video Mirroring, it must have two (or more) separate display cards or adapters. Video Mirroring is not the same as plugging two displays into the same video adapter.

Some PowerBooks, such as the 190-series and the 5300-series, have a built-in secondary display adapter. Other PowerBooks, such as the 1400-series, support third-party expansion cards that provide the same feature.

When you use Video Mirroring, your computer examines the primary monitor (the monitor that has the menu bar on it), and tries to make all other installed displays look the same. Each monitor, however, retains the video settings it had when you first turned on Video Mirroring. This means that a grayscale monitor still appears in grayscale and a color monitor still appears in color.
