Optimizing Digital Conversion Two controls in the on-screen display can be adjusted to improve image performance: Clock and Clock Phase. NOTE: The Clock and Clock Phase controls are adjustable only when using an analog input. These controls are not adjustable for digital inputs. The Clock must first be set correctly since the Clock Phase settings are dependent on the main Clock setting. Use these controls only when the auto-adjustment function does not provide a satisfactory image. ● Clock-Increases/decreases the value to minimize any vertical bars or stripes visible on the screen background. ● Clock Phase-Increases/decreases the value to minimize video distortion or video jitter.
