MAKING CONNECTIONS
NOTE
Avoid keeping a fixed image on the set's
y y
screen for prolonged periods of time. The
fixed image may become permanently
imprinted on the screen; use a screen
saver when possible.
There may be interference relating to
y y
resolution, vertical pattern, contrast or
brightness in PC mode. Change the PC
mode to another resolution or change the
refresh rate to another rate or adjust the
brightness and contrast on the menu until
the picture is clear. If the refresh rate of
the PC graphic card can not be changed,
change the PC graphic card or consult the
manufacturer of the PC graphic card.
The synchronization input waveform for
y y
Horizontal and Vertical frequencies are
separate.
We recommend using 1920x1080, 60
y y
Hz(Except for 42/50PT****, 42/50PW****,
22/26/32LK33**, 19/26/32LV25**,
19/22LV23**), 1024x768, 60 Hz(Only
42/50PT****, 42/50PW****) 1360 x768, 60
Hz(Only 22/26/32LK33**, 19/26/32LV25**,
19/22LV23**) for the PC mode, this should
provide the best picture quality.
Connect the signal cable from the monitor
y y
output port of the PC to the RGB (PC) port
of the TV or the signal cable from the HDMI
output port of the PC to the HDMI IN (or
HDMI/DVI IN) port on the TV.
Connect the audio cable from the PC to the
y y
Audio input on the TV. (Audio cables are
not included with the TV).
If using a sound card, adjust PC sound as
y y
required.
If the graphic card on the PC does
y y
not output analogue and digital RGB
simultaneously, connect only one of either
RGB or HDMI IN (or HDMI/DVI IN) to
display the PC output on the TV.
DOS mode may not work depending on the
y y
video card if you use an HDMI to DVI cable.
If you use too long an RGB-PC cable, there
y y
may be interference on the screen. We
recommend using under 5m of cable. This
provides the best picture quality.

Connecting to an audio system

Use an external audio system instead of the built-
in speaker.
NOTE
If you use an external audio device
y y
instead of the built-in speaker, set the TV
speaker feature to off (See p.73).

Digital optical audio connection

Transmits the digital audio signal from the TV to an
external device. Connect the external device and
the TV with the optical audio cable as shown in the
following illustration.
NOTE
Do not look into the optical output port.
