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.

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

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.

5. Remove the four screws from the monitor stand.

Figure 2-7 Removing the screws from the monitor stand

Save the monitor stand and the four screws, in the event that you decide to convert your monitor back
to a desktop monitor in the future.

8 Chapter 2 Setting Up the Monitor

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 2-8 Positioning the VESA adapter plate

VESA Adapter Plate

b. Secure the lower edge of the VESA adapter plate to the bracket hinge with four screws.

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.

12 Chapter 2 Setting Up the Monitor

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.
