Operating the Monitor 
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.
