Important Safety Information
The power cord is designed for use with your monitor. To use a different cord, use only a power source and 
connection compatible with this monitor.
Safety Precautions
■Use only a power source and connection compatible with this monitor, as indicated on the label/back plate of 
the monitor.
■Be sure the total ampere rating of the products connected to the outlet does not exceed the current rating of the 
electrical outlet, and the total ampere rating of the products connected to the power cord does not exceed the 
rating of the power cord. Look on the power label to determine the ampere rating (Amps or A) for each device.
■Install your monitor near a power outlet that you can easily reach. Disconnect the monitor by grasping the plug 
firmly and pulling it from the outlet. Never disconnect the monitor by pulling the cord.
■Do not allow anything to rest on the power cord. Do not walk on the cord.
WARNING: Always connect your monitor, the computer, and other equipment to a grounded (earthed) power 
outlet. To reduce the risk of electric shock or damage to your equipment, do not disable the power cord grounding 
feature. The grounding plug is an important safety feature.
WARNING: For your safety, 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. To disconnect power from the 
equipment, unplug the power cord from the power outlet by grasping the plug firmly. Never pull on the cord.
CAUTION: To protect your monitor, as well as your computer, connect all power cords for your computer and its 
peripheral devices (such as a monitor, printer, or scanner) to a surge protection device such as a power strip with 
surge protection 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 your equipment if surge 
protection fails.

Audio and Video Cables and Adapters
The following table shows the cable and adapter types that may be required to connect the monitor to the computer, 
TV, or set-top box.
The number and type of cables required may vary by model. Some cables and adapters are included for select 
models only and may be sold separately.
Cable/AdapterNameDescription
HDMI cable HDMI transmits an all-digital signal. It is the 
recommended choice for playback from a DVD 
or DVR.
HDMI is capable of transmitting both 
uncompressed digital audio and digital video 
signals, because it has video, audio, and control 
signals.
DVI cable DVI transmits an all-digital video signal.
VGA cable VGA transmits an analog video signal.
DVI-to-VGA adapter Connects a DVI monitor to a VGA connector on the 
back of the computer, TV, or set-top box or connects 
a VGA monitor to a DVI connector on the back of 
the computer, TV, or set-top box.
DVI-to-HDMI adapter Connects a DVI monitor to an HDMI connector on 
the back of the computer, TV, or set-top box or 
connects an HDMI monitor to a DVI connector on 
the back of the computer, TV, or set-top box.
NOTE: If you use a DVI-to-HDMI adapter, you must 
connect the green audio cable to enable the 
speakers.
VGA-to-DVI-I cable Converts an analog video signal to a digital video 
signal.
NOTE: When using a VGA or DVI signal, you must connect your audio separately because a VGA or DVI signal 
converts only video data, not audio data. A separate audio connection is not necessary when you use an HDMI 
signal, because an HDMI signal can convert both video and audio data.
