a sleep mode.

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, select the Auto Adjust control on the
front bezel.
For more precise adjustments, use the adjustment pattern
provided on the CD-ROM, and adjust the clock and phase
settings (accessed via the OSD) as described in the following
section.
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. Use these controls only
when the auto adjust function does not provide a satisfactory
image.
■ 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.
