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 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.
2.Turn on the power switch on the bottom of the display.
Connecting a Digital TV (HDTV) Signal
To connect an HDTV signal source to the display, connect a coaxial cable between the ATSC input and the TV signal source.

|
|

Connecting Composite Video 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, component video, and HDMI (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 (AV 1 IN, AV 2 IN, or AV 3 IN).
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 composite video block used above.

Setting Up the Display
Connecting S-Video 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 and HDMI (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 Component Video 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 three 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 HDMI Devices
The highest-quality video devices have HDMI |
|
|
outputs. An HDMI cable carries progressive scan |
|
|
video of the highest quality. |
HDMI |
PC-VGA |
To connect an HDMI signal source to the display, use an HDMI cable to connect the source device to the HDMI input on the bottom of the display.
Connecting to an 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 an 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.
To listen to the high-quality digital audio of an HDTV transmission, instead connect the OPTICAL output to your stereo system using an optical digital cable.
