NOTE
► 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 recom mend using 1920x1080, 60
Hz(Except for 22/26/32LD3**,
22/26/32LE53**), 1360x768, 60 Hz(Only
22/26/32LD3**, 22/26/32LE53**) f or the PC
mode, this should provide the best picture quality.
► 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.
► Connect the audio cable from the PC to the Audio
input on the TV. (Audio cables are not included with
the TV).
► If using a sound card, adjust PC sound as required.
► 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 TV.
► If the graphic card on the PC does output analogue
and digital RGB simultaneously, set the TV to either
RGB or HDMI; (the other mode is set to Plug and
Play automatically by the TV.)
► DOS mode may not work depending on the video
card if you use an 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.
