MAKING CONNECTIONS

Connecting to an audio system

Use an external audio system instead of the built-
in speaker.

If you use an external audio device 
instead of the built-in speaker, set the TV 
speaker feature to off (See p.74).

NOTE

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.

Avoid keeping a fixed image on the set’s 

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 

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 

Horizontal and Vertical frequencies are 

separate.

We recommend using 1920x1080, 60 

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.

y

y

Connect the signal cable from the monitor 

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.

y

y

Connect the audio cable from the PC to the 

Audio input on the TV. (Audio cables are 

not included with the TV).

y

y

If using a sound card, adjust PC sound as 

required.

y

y

If the graphic card on the PC does 

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.

y

y

DOS mode may not work depending on the 

video card if you use an HDMI to DVI cable.

y

y

If you use too long an RGB-PC cable, there 

may be interference on the screen. We 

recommend using under 5m of cable. This 

provides the best picture quality.
