Operation

For more precise adjustments, use the Compaq LCD Display
Assistant utility included on the CD-ROM. This utility
graphically illustrates how to adjust the Clock and Clock Phase
controls explained in the Optimizing Digital Conversion section
below.

Optimizing Digital Conversion

This monitor contains advanced circuitry that allows the flat
panel screen to function like a standard monitor. Two controls in
the on-screen display can be adjusted to improve image
performance: Clock and Clock Phase.

Important: The Clock must first be set correctly since the Clock
Phase settings are dependent on the main Clock setting.

Clock—Increase/decrease the value to minimize any vertical
bars or stripes visible on the screen background.

Clock Phase—Increase/decrease the value to minimize video
distortion or video jitter.

When adjusting the Clock and Clock Phase values, if the monitor
images become distorted, continue adjusting the values until the
distortion disappears. To restore the factory settings, select Yes
from the Factory Reset menu in the on-screen display.

User Modes

is not preset if:
