Adjusting Screen Quality; Optimizing Analog Video - HP L1940 User Manual

Adjusting Screen Quality

Allow the monitor to warm up for 20 minutes before performing
the following procedures.
The Auto-adjustment feature automatically fine-tunes the image
quality each time a new video mode is utilized. If additional
improvement is desired, press the Auto adjust button on the front
bezel.
For more precise adjustments, use the adjustment pattern utility
provided on the CD, and adjust the clock and phase settings
(accessed from the OSD menu) as described in the following
section.

Optimizing Analog Video

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. 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/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 using the controls, you will obtain the best results by using
the adjustment pattern application provided on the CD-ROM.
