Product Cautions

TO PREVENT POSSIBLE DANGER, ELECTRIC SHOCK, AND OTHER INJURIES WHEN
HANDLING YOUR DISPLAY, PLEASE BE AWARE OF OF ALL WARNINGS AND SAFETY
PRECAUTIONS LISTED BELOW.

Never spill any liquid of any kind on the display.

Never insert anything into the display, where objects can come into contact with
high voltage nodes or damage internal components.

Do not attempt to service the display yourself. Opening or removing covers
exposes high voltage nodes and other hazards. Refer all servicing to qualified
service personnel.

Do not touch the display or antenna during thunderstorms. Unplug the display
during thunderstorms, or if it will not be used for extended periods. Failure to
do so may result in electric shock or fire.

Before cleaning the display, unplug it from the wall. Use a damp cloth for
cleaning. Never use liquid or aerosol cleaners.

To prevent overheating and ensure reliable operation, place the display only in
a well ventilated location. Avoid cramped or inadequately ventilated locations.
Place the display at least 10 cm (4") from walls or other objects. Always keep the
vent clean. Never place the display upside down.

Note: Read all safety and operating instructions before operating your new display.

Setting Up the Display

The display requires a stable, level, and clean surface near a power outlet, 10 cm (4") away from
walls or other large objects. The rear ventilation grid should be unobstructed, and the display
should not be exposed to water or heat. Before setting up the display, prepare such a space.

To set up the display:

1. Remove the protective plastic bag and plastic screen protector from

the display.

2. Remove the power cord from the accessories box, insert the

appropriate end into the power (AC IN) connector on the bottom of
the display, and then insert the other end into a free power outlet.

3. Turn on the power switch on the bottom of the display.

Connecting to a TV Signal Source

A TV signal may come from a cable box, satellite receiver,
antenna, or similar device.

To connect a TV signal source to the display, connect a coax
cable between the adapter and TV signal source (for example, a
cable box, satellite receiver, or antenna).

Note: If you would like to be able to record

the TV signal with a VCR, DVD
recorder, or similar device, connect
the TV signal source to the input of
the recording device with one cable,
then connect the output of the
recording device to the ANT jack on
the display with another cable.

Connecting to Composite Video Output Devices

Many video devices, such as VCRs, DVD players,
video game systems, and camcorders, have
composite video outputs. Composite video uses
one RCA cable to transmit video information and
generally provides lower quality than S-Video
and component video (see below).

To connect a composite video source to the
display:

1. Using an RCA cable, connect the composite
video output (yellow) on the source device to
the corresponding jack in one of the three
composite video blocks on the display
(AV1IN, AV2IN, or AV3IN).

2. Using two RCA cables, connect the right (red)
and left (white) audio outputs on the source
to the corresponding jacks in the same
composite video block used above.

Connecting to S-Video Output Devices

Many video devices that have composite video outputs also have S-Video outputs. S-Video uses a
single four-wire cable to transmit video information. Two of the wires are used to transmit video.
Because it splits the video signal into two components, S-Video generally provides higher quality
than composite video, but lower quality than component video (see below).

Note: The pins used in S-Video connectors are

somewhat fragile. Take care to avoid
bending the pins, as a bent or broken pin
can cause loss of color information or
total signal loss.

To connect an S-Video source to the display:

1. Using an S-Video cable, connect the S-Video
output on the source device to the S-Video
jack on the display.

2. Using two RCA cables, connect the right (red)
and left (white) audio outputs on the source
to the corresponding jacks in the S-Video
block on the display.

Connecting to Component Video Output Devices

High-quality video devices, such as HDTV
receivers and high-end DVD players, have
component video outputs. Component video
uses three RCA connections to transmit video
information. Because the information is split into
three signals, component video offers higher
quality than composite video and S-Video.

To connect a component video source to the
display:

1. Using the included RCA cables, connect the

three component video outputs to the
corresponding jacks in one of the two
component video blocks on the display.

2. Using two other RCA cables, connect the

right (red) and left (white) audio outputs on
the source to the corresponding jacks in the
same component video block used above.

Connecting to a Peripheral Audio System

Your display has audio outputs that may
be used to play the display’s audio on a
peripheral system, such as a stereo
system or a home theater system. In
addition, there is a subwoofer output
that can be connected to a powered
(amplified) subwoofer to fill out the
bass.

To connect the display to a
peripheral audio system:

1. Using two RCA cables, connect the

right (red) and left (white) audio
outputs in the output block on the
display (AV OUT) to the
corresponding inputs on your audio
system.

2. (OPTIONAL) If you have a powered

(amplified) subwoofer, connect a
third RCA cable from the
SUBWOOFER output on the display
to the subwoofer’s (or amplifier’s) input.

Connecting to a Video Input System

There is a composite video output on the display
that may be used to transmit the currently
displayed video to other video input devices,
such as video recorders or other displays.

To connect the display to a video input
system:

1. Using an RCA cable, connect the composite
video output (yellow) in the output block on
the display (AV OUT) to the corresponding
jack on the video input system.

2. Using two RCA cables, connect the right (red)
and left (white) audio outputs in the AV OUT
block to the corresponding inputs on the
video input system.

Connecting to a PC

Your display can be used as a computer monitor for any computer with a VGA video output. In
addition, the computer’s audio output can be connected to the display and played through the
display’s speakers.

To connect a PC to the display:

1. Set the video resolution on the computer to 1280 × 1024 or less before connecting to the
display (see “Specifications” on page 24 for a full list of supported modes).

In Windows, right-click on the desktop and
select Properties to bring up the Display
Properties window. Select the Settings tab.
Adjust the Screen resolution as needed,
select Apply, then select OK.

2. If your computer has a DVI output, connect a

DVI cable between the DVI output on the
computer and the DVI input on the bottom
of the display.

If your computer has a VGA output only,
connect the VGA cable included in the
accessories box between the VGA output on
the computer and the VGA input on the
display.

3. (OPTIONAL) Using the audio cable included

in the accessories box, connect the
computer’s audio output (LINE OUT) to the

Using Your Display for the First Time

When you turn on your LCD for the first time, you will need to set up the display for proper
operation by scanning the television spectrum for available channels.

Setting up Television Channels

Once the television signal is connected to the display, if you are connecting directly to a wall jack
or antenna, you should scan the signal spectrum to weed out channels with insufficient signal
strength. This will make it much easier to navigate through the channels.

To scan the signal spectrum:

1. Turn the display on using the POWER button.

2. Press SOURCE until the signal source is set to TV.

3. Press the MENU button to bring up the On-Screen
Display (OSD).

4. Press the button until the TV menu shows.

5. Press the ENTER button to enter the menu.

6. Press until Tuner Mode is highlighted, then press
ENTER again to select it.

7. Press the and buttons until the appropriate
system is highlighted, then press the ENTER button
to select it.

Select Air if you are using an antenna.

Select one of the Cable options if you are connecting directly to a cable TV wall outlet.
Contact your cable service provider to find out which system is in use in your area. Cable or
Cable IRC will work with most systems.

8. Press to return to the TV menu.

9. Press until Auto Search is highlighted and then press ENTER to select it.

The display will automatically scan all television channels for those with a strong signal. You
can press ENTER at any time to stop the process.
