2 Setting Up the Monitor
To set up the monitor, ensure that the power is turned off to the monitor, computer system, and other attached devices, and then follow the instructions below.
Extending the Monitor Stand
1. Lift the monitor from its box and place it face down on a flat surface.
2. Grasp the stand and pull upward until fully extended.
CAUTION: Do not touch the surface of the panel. Pressure on the panel may cause permanent
non-uniformity of color or disorientation of the liquid crystals.
Figure 2-1 Extending the monitor stand
3. Place the monitor in an upright position on a flat surface so that the feet are touching the surface.
Press down firmly on the top center area of the monitor to ensure that the monitor is stable.

Connecting the Cables
1. Place the monitor in a convenient, well-ventilated location near the computer.
Figure 2-3 Connecting the monitor
2. Connect one end of the DisplayPort signal cable (provided with select models) to the DisplayPort
connector on the side of the monitor and the other end to the DisplayPort connector on the computer.
3. Connect one end of the HDMI signal cable (provided with select models) to the HDMI connector
on the side of the monitor and the other end to the HDMI connector on the computer.
4. Connect the power adapter cord to the power connector on the side of the monitor. Connect one
end of the power cord to the power supply brick and the other end to an electrical wall outlet.
WARNING! To reduce the risk of electric shock or damage to the 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 that is easily accessible at all times.
Disconnect power from the equipment 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.

A stable flat surface covered with a soft, clean cloth (such as a clean, large towel) to protect the monitor when you place it face down
Another person (it might require two people to lift and move the monitor)
Antistatic wrist strap and a conductive foam pad to stand on while attaching the VESA adapter plate (recommended)
VESA device (sold separately) with the following specifications:
VESA standard 100 mm x 100 mm (3.9 in x 3.9 in) hole pattern
Provides at least 58 mm (2.28 inches) space behind the monitor for the monitor power cord and cables

Safety Information
This product has not been evaluated for connection to an “IT” power system (an AC distribution system with no direct connection to the earth, according to IEC 60950).
WARNING! Always disconnect the monitor from the power source before lifting, moving, or
removing the stand from your monitor. Failure to do so can result in personal injury or equipment damage.
Removing the Stand from the Monitor
To avoid injury and equipment damage, always complete the following steps in order:
1. Turn the monitor off and disconnect the power cord from the wall outlet.
CAUTION: Static electricity can damage the electronic components of the monitor or other
equipment. Ensure that you are discharged of static electricity by briefly touching a grounded metal object.
2. Disconnect any equipment and all attached cables from the monitor before beginning this
procedure.
3. Lay the monitor face down on a flat surface covered by a clean, dry cloth.
4. Remove the detachable hinge cover.

Installing the VESA Adapter Plate onto the Monitor
NOTE: This apparatus is intended to be supported by a UL or CSA Listed wall-mount bracket.
1. Remove the stand from the monitor panel. Refer to Removing the Stand from the Monitor
on page 7.
2. Install the VESA adapter plate that shipped with the monitor.
a. With the monitor face down on the table, slide the VESA adapter plate from the lower edge
of the monitor toward the bracket hinge until the VESA adapter plate is in position over the bracket hinge.

Figure 2-9 Securing the VESA adapter plate
3. To attach the monitor to a VESA-compatible device (purchased separately), follow the instructions
included with that device to ensure that the monitor is safely attached.
CAUTION: This monitor supports the VESA industry-standard 100 mm mounting holes. To attach
a third-party solution to the monitor, four 4 mm, 0.7 pitch, and 10 mm long screws (purchased separately) are required. Longer screws must not be used because they may damage the monitor. It is important to verify that the manufacturer’s solution is compliant with the VESA standard and is rated to support the weight of the monitor display panel. For best performance, it is important to use the power and video cables provided with the monitor.
4. Reconnect the cables to the monitor panel.
Removing the VESA Adapter Plate
To avoid injury and equipment damage, always complete the following steps in order:
1. Turn the monitor off and disconnect the power cord from the wall outlet.
CAUTION: Static electricity can damage the electronic components of the monitor or other
equipment. Ensure that you are discharged of static electricity by briefly touching a grounded metal object.
2. Disconnect any equipment and all attached cables from the monitor before beginning this
procedure.
3. To remove the monitor from a mounting device, follow the instructions included with that device to
safely detach the monitor and remove any mounting hardware.

Turning on the Monitor
1. Press the power button on the front of the monitor to turn it on.
2. Press the power button on the computer to turn it on.
CAUTION: Burn-in image damage may occur on monitors that display the same static image on the
screen for a prolonged period of time (12 or more consecutive hours of non-use). To avoid burn-in image damage on the monitor screen, you should always activate a screen saver application or turn off the monitor when it is not in use for a prolonged period of time. Image retention is a condition that may occur on all LCD screens. Monitors with a burned-in image are not covered under the HP warranty.
When the monitor is powered on, the power LED on the front of the monitor is blue.
Locating the Rating Label
The rating label on the monitor provides the spare part number, product number, and serial number. You may need these numbers when contacting HP about the monitor model. The rating label is located on the rear panel of the monitor.

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 warmup 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 power­management 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.
