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, then follow the instructions below.  
Attaching the Monitor Base  
CAUTION: The screen is fragile. Avoid touching or applying pressure to the screen; doing so can  
cause damage.  
TIP: For monitor displays with glossy bezels, consider the placement of the display, because the  
bezel might cause interfering reflections from surrounding light and bright surfaces.  
1. Lift the monitor from its box and place it face down on a flat surface.  
2. Insert the stand into the slot on the back of the display head until it clicks.

Connecting the Cables  
1. Place the monitor in a convenient, well-ventilated location near the computer.  
2. Connect a signal cable.  
NOTE: The monitor is capable of supporting analog, digital, or HDMI input. The video mode is  
determined by the video cable used. The monitor will automatically determine which inputs have  
valid video signals. The inputs can be selected by pressing the +/source button on the front panel  
or through the On-Screen Display (OSD) feature by pressing the Menu button.  
For analog operation, use a VGA signal cable. Connect the VGA signal cable to the VGA  
connector on the rear of the monitor and the other end to the VGA connector on the  
computer.

Chapter 2 Setting Up the Monitor  
 
For DVI digital operation, use a DVI-D signal cable. Connect the DVI-D signal cable to the  
DVI connector on the rear of the monitor and the other end to the DVI connector on the  
computer.  
Figure 2-5 Connecting a DVI Signal Cable (provided with select models)  
OR  
Connect one end of the HDMI cable to the HDMI connector on the back of the monitor (select  
models) and the other end of the HDMI cable to the input device. The HDMI cable is not  
included. Connect the HDMI signal cable to the HDMI connector on the rear of the monitor  
and the other end to the HDMI connector on the computer.

3. Connect the round end of the power supply cord to the monitor, and then connect one end of the  
power cord to the power supply and the other end to a grounded electrical outlet.  
Figure 2-7 Connecting the Power Cable  
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.

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  
screen for a prolonged period of time.* 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.  
* A prolonged period of time is 12 consecutive hours of non-use.  
NOTE: If pressing the power button has no effect, the Power Button Lockout feature may be enabled.  
To disable this feature, press and hold the monitor power button for 10 seconds.  
NOTE: You can disable the power LED in the OSD menu. Press the Menu button on the front of the  
monitor, then select Management > Bezel Power LED > Off.  
When the monitor is powered on, a Monitor Status message is displayed for five seconds. The message  
shows which input (VGA, DVI, or HDMI) is the current active signal, the status of the auto-switch source  
setting (On or Off; factory default is On), the default source signal (factory default is Auto-switch), the  
current preset display resolution, and the recommended preset display resolution.  
10  
Chapter 2 Setting Up the Monitor  
   
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: DVI, HDMI, then VGA. You can change the default source in the OSD by pressing the  
front panel Menu button and selecting Source Control > Default Source.  
HP Watermark and Image Retention Policy  
The IPS monitor models are designed with IPS (In-Plane Switching) display technology which provides  
ultra-wide viewing angles and advanced image quality. IPS monitors are suitable for a wide variety of  
advanced image quality applications. This panel technology, however, is not suitable for applications  
that exhibit static, stationary or fixed images for long periods of time without the use of screen savers.  
These types of applications may include camera surveillance, video games, marketing logos, and  
templates that are displayed on the screen for a prolonged period of time. Static images may cause  
image retention damage that could look like stains or watermarks on the monitor's screen.  
Monitors in use for 24 hours per day that result in image retention damage are not covered under the  
HP warranty. To avoid image retention damage, always turn off the monitor when it is not in use or use  
the power management setting, if supported on your system, to turn off the display when the system is  
idle.  
Locating the Rating Label  
The rating label on the monitor provides the product number and serial number. You may need these  
numbers when contacting HP about the monitor model. The rating label is located on the bottom of the  
monitor.

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.

Appendix A Technical Specifications  
   
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.
