TOPIC Sometimes when trying to watch QuickTime movies on both the PowerBook display and an external monitor (in Simulscan mode), the video only shows up on the PowerBook display. Why is this? DISCUSSION The second generation PowerBook G3 Series have the ATI LT Pro video hardware which is capable of displaying multiple resolutions on the built-in PowerBook display. If the ATI Driver Update 1.4.7 or later is installed, this computer is capable of displaying the same image on the internal screen and an external monitor at multiple resolutions. However, when viewing some QuickTime movies or DVD video, the video may only show up on the PowerBook display if the simulscan resolution is not the "native" resolution. On a 14" or 13" display, the native resolution is 1024 x 768. On a 12" display the native resolution is 800 x 600. So to resolve the issue, change the resolution to the native resolution for your screen size. Note: Macintosh PowerBook G3 Series computers should not be confused with Macintosh PowerBook G3 computers. Though the names are similar, there are significant differences. To visually identify which type of computer you have, close the display and inspect the display case. A Macintosh PowerBook G3 has a small, six-color Apple logo on the display case. A Macintosh PowerBook G3 Series computer has a large Apple logo on the display case that is not six-colored. |
