Using Auto-Sleep Mode
The monitor supports an OSD (On-Screen Display) menu option called Auto-Sleep
Mode that allows you to enable or disable a reduced power state for the monitor.
When Auto-Sleep Mode is enabled (enabled by default), the monitor will enter a
reduced power state when the host PC signals low power mode (absence of either
horizontal or vertical sync signal).
Upon entering this reduced power state (sleep mode), the monitor screen is blanked,
the backlight is turned off and the power LED indicator turns amber. The monitor
draws less than 0.5 W of power when in this reduced power state. The monitor will
wake from the sleep mode when the host PC sends an active signal to the monitor (for
example, if you activate the mouse or keyboard).
You can disable Auto-Sleep Mode in the OSD. Press one of the four front bezel
Function buttons to activate the buttons, and then press the Menu button to open the
OSD. In the OSD menu select Power Control > Auto- Sleep Mode > Off.

Adjusting Screen Quality (VGA only)
The auto adjustment feature automatically fine-tunes the image quality for display
size, position, clock, and phase each time a new video mode is displayed. For more
precise adjustments of VGA input, run the Auto Adjustment software available on your
product support site at www.hp.com/support. If you want additional image quality
improvement, use the Clock and Phase controls of the monitor to fine tune the image.
See "Optimizing Analog Video" in this chapter.
Optimizing Analog Video
Some monitors contain advanced circuitry that allow the monitor to function as a
standard analog monitor. Two controls in the OSD menu can be adjusted to improve
analog image performance:
Clock - Increase or decrease the value to minimize any vertical bars or stripes visible
on the screen background.
Phase - Increase or decrease the value to minimize video distortion or video jitter.
Use these controls only when the auto adjustment function does not provide a
satisfactory monitor image in analog mode. To obtain the best results:
1. Allow the monitor to warm up for 30 minutes before adjusting.
2. Access the OSD menu, then select Image Setup.
3. Set the main Clock settings correctly first, because the Phase settings depend on
the main Clock settings.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, access the OSD menu,
select Factory Reset, and then select Yes.
Power-Saver Feature
When the monitor is in normal operating mode, the Power light is blue and the monitor
uses the normal watts of power. For power usage, refer to "Technical Specification"
(Appendix B). The monitor also supports a power-saver mode that is controlled by the
computer. When the monitor is in the reduced-power state, the monitor screen is
blank, the backlight is off, and the Power light is amber. The monitor uses minimum
power. When the monitor is "awakened", a brief warm-up period occurs before the
monitor returns to normal operating mode. The energy-saving reduced power state
activates if the monitor does not detect either the horizontal sync signal or the vertical
sync signal. The power-saver feature must be activated on your computer for this
feature to work. Refer to your computer documentation for instructions on setting
energy-saver features (sometimes called power-management features).
NOTE: The energy-saver feature works only when the monitor is connected to
computers that have energy-saver features.

LCD Monitor Quality and Pixel Policy
Your LCD Monitor uses high-precision technology, manufactured according to high
standards, to help 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 your LCD Monitor. These imperfections are caused by one or more
defective pixels or subpixels.
A pixel consists of one red, one green, and one blue subpixel. 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
subpixel (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 and in normal operating mode at a supported resolution and refresh rate,
from a distance of approximately 50 cm (16 inches). We expect that, over time, the
industry will continue to improve its ability to produce displays with fewer cosmetic
imperfections, and we will adjust guidelines as improvements are made. For more
information about your LCD Monitor, refer to the HP Web site at:
http://www.hp.com/support.
