Operating the Monitor
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-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.
