HP Compaq LA1905wg, LA2205wg, LA22f, and LA2405wg LCD Monitors - Operating the Monitor

Software and Utilities

The CD that comes with the monitor contains files you can install on the computer:

  • an .INF (Information) file

  • an .ICM (Image Color Matching) file

  • auto-adjustment pattern utility

  • additional software for the monitor model

If the monitor does not include a CD, the .INF and .ICM files can be downloaded from the HP monitors support Web site. See Downloading from the Worldwide Web in this chapter.

The Information File

The .INF file defines monitor resources used by Microsoft Windows operating systems to ensure monitor compatibility with the computer’s graphics adapter.

This monitor is Microsoft Windows Plug and Play compatible and the monitor will work correctly without installing the .INF file. Monitor Plug and Play compatibility requires that the computer’s graphic card is VESA DDC2–compliant and that the monitor connects directly to the graphics card. Plug and Play does not work through separate BNC type connectors or through distribution buffers/boxes.

The Image Color Matching File

The .ICM files are data files that are used in conjunction with graphics programs to provide consistent color matching from monitor screen to printer, or from scanner to monitor screen. This file is activated from within graphics programs that support this feature.

The ICM color profile is written in accordance with the International Color Consortium (ICC) Profile Format specification.

Installing the .INF and .ICM Files

After you determine that you need to update, you can install the .INF and .ICM files from the CD or download them.

Optimizing Digital Conversion

Two controls in the on-screen display can be adjusted to improve image performance: Clock and Clock Phase.

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.

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.

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

Identifying Monitor Conditions

Special messages will appear on the monitor screen when identifying the following monitor conditions:

  • Monitor Status—When the monitor is powered on or when the input source signal is changed, a Monitor Status message is displayed for five seconds. The message shows which input is the current active signal, the status of the auto-switch source setting (On or Off), the default source signal, the current preset display resolution, and the recommended preset display resolution.

  • Input Signal Out of Range—Change resolution setting to 1440 x 900 – 60Hz—Indicates the monitor does not support the input signal because the resolution and/or refresh rate are set higher than the monitor supports (model LA1905wg).
