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 DDC2b-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. The .ICM file contains
a monitor color system profile. This file is activated from within graphics programs that support this feature.

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.
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.

HP Display LiteSaver
HP Display LiteSaver is a software application, available on the CD, that increases monitor life and saves
energy. It allows you to place the monitor into its low power sleep mode at predefined times by shutting
down or reducing power to most internal circuits. This helps protect the LCD panel against image retention.
Image retention can occur when the monitor is left on while displaying the same image for an extended
period of time, leaving a shadow of the image on the screen.

●ꢀ 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
or HP Display Assistant software. Your changes can be made to any or all of these modes and saved in

memory. The monitor automatically stores the new setting, then recognized the new mode just as it does
a preset mode. In addition to the 15 factory present modes for the L1745 model, there are four user modes
that can be entered and stored.
Energy Saver Feature
When the monitor is in its normal operating mode, the monitor uses less than 70 watts of power and the
Power light is green.
The monitor also supports 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 less
than 2 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.

LCD Monitor Quality and Pixel Policyꢀ
The TFT monitor uses high-precision technology, manufactured according to HP standards, to guarantee
trouble-free performance. Nevertheless, the display may have cosmetic imperfections that appear as small
bright or dark spots. This is common to all LCD displays used in products supplied by all vendors and is
not specific to the HP LCD. These imperfections are caused by one or more defective pixels or sub-pixels.
●ꢀ A pixel consists of one red, one green, and one blue sub-pixel.
●ꢀ A defective whole pixel is always turned on (a bright spot on a dark background), or it is always off
(a dark spot on a bright background). The first is the more visible of the two.
●ꢀ A defective sub-pixel (dot defect) is less visible than a defective whole pixel and is small and only
visible on a specific background.
To locate defective pixels, the monitor should be viewed under normal operating conditions, in normal
operating mode at a supported resolution and refresh rate, from a distance of approximately 50 cm (20
in).
HP expects that, over time, the industry will continue to improve its ability to produce LCDs with fewer
cosmetic imperfections and HP will adjust guidelines as improvements are made.
