2 Safety and Maintenance Guidelines  
Important Safety Information  
A power cord is included with the monitor. If another cord is used, use only a power source and  
connection appropriate for this monitor. For information on the correct power cord set to use with the  
monitor, refer to the "Connecting the Power Cord" section in Setting Up the Monitor on page 6.  
WARNING! To reduce the risk of electric shock or damage to the equipment:  
• Do not disable the power cord grounding feature. The grounding plug is an important safety feature.  
• Plug the power cord in a grounded (earthed) outlet that is easily accessible at all times.  
• Disconnect power from the product by unplugging the power cord from the electrical outlet.  
For your safety, do not place anything on power cords or cables. Arrange them so that no one may  
accidentally step on or trip over them. Do not pull on a cord or cable. When unplugging from the  
electrical outlet, grasp the cord by the plug.  
To reduce the risk of serious injury, read the Safety and Comfort Guide. It describes proper  
workstation, setup, posture, and health and work habits for computer users, and provides important  
electrical and mechanical safety information. This guide is located on the Web at http://www.hp.com/  
ergo and/or on the documentation CD, if one is included with the monitor.  
CAUTION: For the protection of the monitor, as well as the computer, connect all power cords for  
the computer and its peripheral devices (such as a monitor, printer, scanner) to some form of surge  
protection device such as a power strip or Uninterruptible Power Supply (UPS). Not all power strips  
provide surge protection; the power strips must be specifically labeled as having this ability. Use a  
power strip whose manufacturer offers a Damage Replacement Policy so you can replace the  
equipment, if surge protection fails.  
Use the appropriate and correctly sized furniture designed to properly support your HP LCD monitor.  
WARNING! LCD monitors that are inappropriately situated on dressers, bookcases, shelves, desks,  
speakers, chests, or carts may fall over and cause personal injury.  
Care should be taken to route all cords and cables connected to the LCD monitor so that they can not  
be pulled, grabbed, or tripped over.

WARNING! To reduce the risk of electric shock or damage to your equipment:  
Do not disable the power cord grounding plug. The grounding plug is an important safety  
feature. Plug the power cord into a grounded (earthed) electrical outlet.  
Be sure that the grounded power outlet you plug the power cord into is easily accessible to the  
operator and located as close to the equipment as possible. A power cord should be routed so  
that it is not likely to be walked on or pinched by items that are placed upon it or against it.  
Do not place anything on power cords or cables. Arrange them so that no one may accidentally  
step on or trip over them. Do not pull on a cord or cable.  
See Technical Specifications on page 24 for additional information.  
2. Connect the round end of the power supply cord to the monitor then connect one end of the  
power cord to the power supply and the other end to a grounded electrical outlet.  
WARNING! To prevent injury from electrical shock, you should do one of the following if a  
properly grounded electrical outlet is not available: (1) You should use an electrical outlet  
adapter that provides proper grounding. (2) You should have a properly grounded electrical  
outlet installed.  
Figure 3-6 Connecting the Power Cord  
High-Bandwidth Digital Content Protection (HDCP)  
Your monitor supports HDCP and can receive high-definition content. High-definition content is  
available in many sources, such as Blu-ray Disc devices or HDTV air or cable broadcasts. If you do  
not have an HDCP-enabled monitor, you will see a blank screen or a lower resolution picture when  
playing high-definition protected content. Your computer graphics card and monitor must both support  
HDCP to display protected content.

preset display resolution.  
Selecting Video Input Connectors  
The input connectors are:  
DisplayPort (digital)  
DVI-D connector (digital)  
HDMI connector (digital) 2310e model  
The monitor automatically scans the signal inputs for an active input and uses that input for the  
display. If two inputs are active, the monitor will display the default input source. If the default source  
is not an active input, then the monitor will display the other input if it is active. You can change the  
default source in the OSD by pressing the front panel Menu button and selecting Source Control >  
Default Source.  
Adjusting The Tilt  
For optimal viewing, adjust the screen tilt to your own preference, as follows:

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, the Power light is  
amber, and 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.

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 ten user modes that can be entered and  
stored.

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 and pixel policy, refer to the HP Web site at:  
http://www.hp.com/support. To find pixel policy information on the HP Web site, type in "HP Pixel  
Policy" in the search box and press Enter.

period of user inactivity. When used with an external ENERGY STAR® qualified display, this feature  
also supports similar power management features for the display. To take advantage of these  
potential energy savings, users should use the default power management settings that are provided  
with ENERGY STAR qualified computers and displays. The default power management settings on  
ENERGY STAR qualified computers are preset to behave in the following ways when the system is  
operating on AC power:  
Turn off an external display after 15 minutes of user inactivity  
Initiate a low power sleep mode for the computer after 30 minutes of user inactivity  
ENERGY STAR® qualified computers exit the low power sleep mode and ENERGY STAR qualified  
displays resume operation when the user resumes use of the computer. Examples include the user
