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. User Guide 4–9
