Repair Issue: Display Service Utility
The Display Service Utility (on the Service Source
Companion CD: Diagnostic Utilities folder) is an application
that you can use to display video test patterns, restore
display settings, run some troubleshooting procedures, and
adjust geometry.
Within the Display Service Utility, select Pattern
Selections: AppleVision 850/850AV, and click the Adjust
Geometry button.
Clicking the Adjust Geometry button opens a screen of scroll
bars that you can use to make various geometry adjustments.
Although most of these adjustments can be duplicated by
using the Monitors & Sound control panel, high voltage can
only be adjusted with the Display Service Utility.
