Operating the Monitor
User’s Guide 4–9
Optimizing Analog Video
This monitor contains advanced circuitry that allows the flat panel
screen to function as a standard monitor. Two controls in the
on-screen display can be adjusted to improve image performance:
Clock and Clock Phase. Use these controls only when the
auto-adjust function does not provide a satisfactory image.
✎
The Clock must first be set correctly since the Clock Phase settings
are dependent on the main Clock setting.
■ Clock — Increase or decrease the value to minimize any
vertical bars or stripes visible on the screen background.
■ Clock Phase — Increase or decrease the value to minimize
video distortion or video jitter.
✎
When using the controls, you will obtain the best results by using
the adjustment pattern application provided on the CD-ROM.
✎
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.
