4 Operating the monitor
Software and utilities
The disc that comes with the monitor contains files you can install on the computer:
an .INF (Information) file
●
ICM (Image Color Matching) files (one for each calibrated color space)
●
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.
NOTE: The ICM color profile is written in accordance with the International Color Consortium (ICC)
Profile Format specification.

Entering user modes
The video controller signal may occasionally call for a mode that is not preset if:
You are not using a standard graphics adapter.
●
You are not using a preset mode.
●
It this occurs, you may need to readjust the parameters of the monitor screen by using the on-screen
display. Your changes can be made to any or all of these modes and saved in memory. The monitor
automatically stores the new setting, then recognizes the new mode just as it does a preset mode. In
addition to the factory preset modes, there are at least 10 user modes that can be entered and
stored.
Energy saver feature
The monitors support a reduced power state. The reduced power state will be entered into if the
monitor detects the absence of either the horizontal sync signal and/or the vertical sync signal. Upon
detecting the absence of these signals, the monitor screen is blanked, the backlight is turned off, and
the power light is turned amber. When the monitor is in the reduced power state, the monitor will
utilize .5 watts of power. There is a brief warm up period before the monitor will return to its normal
operating mode.
Refer to the computer manual for instructions on setting energy saver features (sometimes called
power management features).
NOTE: The above power saver feature only works when connected to computers that have energy
saver features.
By selecting the settings in the monitor's Energy Saver utility, you can also program the monitor to
enter into the reduced power state at a predetermined time. When the monitor's Energy Saver utility
causes the monitor to enter the reduced power state, the power light blinks amber.

Solving common problems 23
Using the Auto-Adjustment Function (Analog Input)
When first setting up the monitor, when conducting a Factory Reset of the computer, or whenever you
change the resolution of the monitor, the Auto-Adjustment feature will automatically engage, and
attempt to optimize your screen for you.
You may also optimize the screen performance for the VGA (analog) input at any time by using the
Auto button on the monitor (see your model's user guide for the specific button name) and the auto-
adjustment pattern software utility on the disc provided (select models only).
Do not use this procedure if the monitor is using an input other than VGA. If the monitor is using a
VGA (analog) input, this procedure can correct the following image quality conditions:
Fuzzy or unclear focus
●
Ghosting, streaking or shadowing effects
●
Faint vertical bars
●
Thin, horizontal scrolling lines
●
An off-center picture
●
To use the auto-adjustment feature:
1. Allow the monitor to warm up for 20 minutes before adjusting.
2. Press the Auto button on the monitor front panel.
You can also press the Menu button, then select Image Control > Auto-Adjustment from the
●
OSD Main Menu.
If the result is not satisfactory, continue with the procedure.
●
3. Insert the disc in the disc drive. The disc menu is displayed.
4. Select Open Auto-Adjustment Software. The setup test pattern is displayed.
5. Press the Auto button on the monitor front panel to produce a stable, centered image.
6. Press the ESC key or any other key on the keyboard to exit the test pattern.
NOTE: The auto-adjustment test pattern utility can be downloaded from http://www.hp.com/support.
24 Appendix B Support and troubleshooting
Optimizing Image Performance (Analog Input)
Two controls in the on-screen display can be adjusted to improve image performance: Clock and
Phase (available in the main menu).
NOTE: The Clock and Phase controls are adjustable only when using an analog (VGA) input. These
controls are not adjustable for digital inputs.
The Clock must first be set correctly since the 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.
Phase—Increases/decreases the value to minimize video flickering or blurring.
●
NOTE: When using the controls, you will obtain the best results by using the auto-adjustment
pattern software utility provided on the disc.
When adjusting the Clock and 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.
To eliminate vertical bars (Clock):
1. Press the Menu button on the monitor's front panel to open the OSD Menu, and then select
Image Control > Clock.
2. Press the + (Plus) or – (Minus) buttons on the monitor's front panel to eliminate vertical bars.
Press the buttons slowly so that you do not miss the optimum adjustment point.
3. After adjusting the Clock, if blurring, flickering, or bars appear on the screen, proceed to adjust
the Phase.
To remove flickering or blurring (Phase):
1. Press the Menu button on the monitor's front panel to open the OSD Menu, and then select
Image Control > Phase.
2. Press the + (Plus) or – (Minus) buttons on the monitor's front panel to eliminate flickering or
blurring. Flicking or blurring may not be eliminated depending on your computer or graphics
controller card installed.
To correct screen position (Horizontal Position or Vertical Position):
Optimizing Image Performance (Analog Input) 25
1. Press the Menu button on the monitor's front panel to open the OSD Menu, and then select
Image Control > Horizontal Position and/or Vertical Position.
2. Press the + (Plus) or – (Minus) buttons on the monitor's front panel to properly adjust the
position of the image in the display area of the monitor. The Horizontal Position shifts the image
left or right; the Vertical Position shifts the image up and down.
Button lockouts
Holding down the power button or Menu button for ten seconds will lock out the functionality of that
button. You can restore the functionality by holding the button down again for ten seconds. This
functionality is only available when the display is powered on, displaying an active signal, and the
OSD is not active.
