Operating the Monitor 
For more precise adjustments, run the Adjustment Pattern 
provided on the CD and use the Clock and Clock Phase controls 
(accessible from the OSD menu) 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. 
✎ 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 Auto-Adjustment pattern application provided on the CD. 
✎ 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.

HP Display LiteSaver (Available with 
Select Models) 
HP Display LiteSaver is a software application, available on the 
CD, that increases monitor life and saves energy. It allows you to 
place your monitor into its low power sleep mode at predefined 
times by shutting down or reducing power to most internal 
circuits. This helps protect the LCD panel against image 
retention. Image retention can occur when the monitor is left on 
while displaying the same image for an extended period of time, 
leaving a shadow of the image on the screen. 
Installing the HP Display LiteSaver Software 
1. Insert the CD in the computer CD-ROM Drive. The CD menu 
displays. 
2. Select “Install HP Display LiteSaver Software.” 
3. After installing the software, click the HP Display LiteSaver 
icon in the Windows system tray or right-click the icon and 
select Configure... from the pop-up menu.
