EXTERNAL EQUIPMENT SETUP

NOTE

To enjoy vivid picture and sound, connect a PC to

the set.

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.

Connect the PC to the RGB (PC) or HDMI IN (or

HDMI/DVI IN) port of the set; change the resolu-

tion.

There might be noise according to some 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 pic-

ture 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 1366x768, 60Hz (32, 37 ,42inch

LCD TV models)/ 1920x1080, 60Hz (47, 52inch LCD TV

models) / 1024x768, 60Hz (42 inch PLASMA TV models)

/ 1360x768, 60Hz (50 inch PLASMA TV models) for the

PC mode, these should provide the best picture quality.

Connect the signal cable from the monitor output

port of the PC to the RGB (PC/DTV) port of the

set or the signal cable from the HDMI output port

of the PC to the HDMI IN (or HDMI/DVI IN) port

on the set.

Connect the audio cable from the PC to the Audio

input on the set. (Audio cables are not included

with the set).

If using a sound card, adjust PC sound as required.

This set uses a VESA Plug and Play Solution. The

set provides EDID data to the PC system with a

DDC protocol. The PC adjusts automatically when

using this set.

DDC protocol is preset for RGB (Analog RGB),

HDMI (Digital RGB) mode.

If required, adjust the settings for Plug and Play

functionality

If the graphic card on the PC does not output ana-

logue and digital RGB simultaneously, connect only

one of either RGB or HDMI IN (or HDMI/DVI IN) to

display the PC output on the set.

If the graphic card on the PC does output analogue

and digital RGB simultaneously, switch the TV set to

either RGB or HDMI; (the other mode is set to Plug

and Play automatically by the set.)

DOS mode may not work depending on the video

card if you use a HDMI to DVI cable.

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
