setting (On or Off; factory default is On), the default source signal (factory default is DisplayPort), the
current preset display resolution, and the recommended preset display resolution.
The monitor automatically scans the signal inputs for an active input and uses that input for the display.
If two or more inputs are active, the monitor will display the default input source. If the default source is
not one of the active inputs, then the monitor will display the highest ranking priority input in the
following order: DisplayPort, DVI, then VGA. You can change the default source in the OSD by

parameters when a USB device is either removed or
connected. Try removing the USB cable again, wait for at
least five seconds, and then plug it in again.
Multi-touch gestures do not function on Windows 7 Home
Basic or Starter editions, Windows Vista, or Windows XP.
Only Windows 7 Home Premium, Professional, Enterprise,
and Ultimate editions support multi-touch gestures.
The Start, Close, and other icons are too small to touch with Windows 7 provides a large icon feature that supports touch
a finger.
screen functions. This feature can be accessed in the Control
Panel. A stylus may also be used.
Touch operation does not function properly on lower-
resolution video modes that are not displayed in fullscreen.
Although the monitor supports a fill-to-aspect ratio function, the
touch controller does not know how to respond to less-than-
fullscreen images. Either change the resolution to 1920 x
1080, or access the OSD menu and select Image Control
to enable Fill-to-Screen (default setting).
A single touch is recognized as two touches. If using a paint
tool, a single finger creates two lines.

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
0.5 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.

Appendix A Technical specifications
B LCD monitor quality and pixel
policy
The TFT monitor uses high-precision technology that is 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, and 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.
