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.

NOTE: When using the controls, you will obtain the best results by using the auto-adjustment pattern software utility 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.

Using the HP Display Assistant Utility

HP Display Assistant, included on the software and documentation CD, is a software utility that guides you through the tuning process with easy to understand instructions and background patterns designed for each monitor control. It provides:

Accurate screen calibration through the use of step-by-step instruction Wizards to obtain the best overall image quality.

Software control of the monitor image and color settings to eliminate dependence on the monitor’s front panel buttons and On-Screen Display (OSD) menu.

Defined preset display settings for each individual user in a multi-user environment.

Multiple preset display settings for a single user based on content and ambient lighting.

Asset Management and Power Management capabilities that include remote control for individual or a group of displays on the domain from a centralized console application.

The HP Display Assistant Utility has two modes of operation: Wizard and OSD mode. The preferred method of use is Wizard mode, which takes you through a step-by-step process to accurately calibrate the monitor. This method relies on a sequence of steps that will obtain the best display results when completed.

NOTE: Refer to the HP Display Assistant user guide for additional information about the software.
