Selecting Video Input Connectors
The input connectors are:
•
•
VGA connector (analog)
DVI-D connector (digital)
The monitor automatically determines which inputs have valid video signals, and
displays the image.
You can connect the VGA cable, the DVI-D cable, or both. If both cables are installed,
the default input selection is DVI.The source of input can be switched using the Input
Select option in the OSD menu.
Identifying Monitor Conditions
Special messages appear on the monitor screen for the following monitor conditions:
Input Signal Out of Range - When the Hsync Frequency, Vsync Frequency or
Resolution is out of the monitor support range, The monitor will show this message.
No Signal - When the video cable is not connected, or the video cable is connected
but there is no active signal input, the monitor will show this message, after 9 seconds
the monitor will enter power saving. This message location is at the position setting in
"OSD Setup" item.
Auto Adjustment in Progress - Indicates the auto adjustment function is active. See
"Adjusting Screen Quality" in this chapter.
Adjusting Screen Quality
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 on the CD. 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
(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:
