Operating the Monitor Optimizing Analog Video This monitor contains advanced circuitry that allows the flat panel screen to function like a standard monitor.

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. ✎ When adjusting the Clock and Clock Phase values, if the monitor images become distorted, continue adjusting the values until the distortion disappears.
