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 cannot 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,
y

60 Hz(Except for 42/50PT25**,
42/50PW35**, 42/50PW45**,
22/26/32LK33**, 19/22/26/32LV25**,
26/32LV30**), 1360x768, 60 Hz(Only
22/26/32LK33**, 19/22/26/32LV25**,
26/32LV30**), 1024x768, 60 Hz(Only
42/50PT25**, 42/50PW35**,
42/50PW45**) 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
y
y
the Audio input on the TV. (Audio cables
are not included with the TV).
If using a sound card, adjust PC sound
y
y
as 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
y
y
the video card if you use an HDMI to DVI
cable.
If you use too long an RGB-PC cable,
y
y
there may be interference on the screen.
We recommend using under 5m of cable.
This provides the best picture quality.

in speaker.
NOTE

y
y
instead of the built-in speaker, set the TV
speaker feature to off (See p.74).
