NOTE
Avoid keeping a fixed image on the set's screen
G
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,
G
vertical pattern, contrast or brightness in PC
mode. Change the PC mode to another resolu-
tion 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
G
Horizontal and Vertical frequencies are separate.
We recommend using 1920x1080, 60Hz(Except
G
for 19/22LU40 **, 19LU50 **,
19/22/26/32/37/42LH20 ** ), 1360x768,
60Hz(Only 19/22LU40 **, 19LU50 **,
19/22/26/32/37/42LH20 ** ) for the PC mode,
this should provide the best picture quality.
Connect the signal cable from the monitor out-
G
put 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
G
Audio input on the TV. (Audio cables are not
included with the TV).
If using a sound card, adjust PC sound as
G
required.
This TV uses a VESA Plug and Play Solution. The
G
TV provides EDID data to the PC system with a
DDC protocol. The PC adjusts automatically
when using this TV.
DDC protocol is preset for RGB (Analogue RGB),
G
HDMI (Digital RGB) mode.
If required, adjust the settings for Plug and Play
G
functionality
If the graphic card on the PC does not output
G
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.
If the graphic card on the PC does output analogue
G
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
G
card if you use an HDMI to DVI cable.
If you use too long an RGB-PC cable that is too
G
long, there may be interference on the screen.
We recommend using under 5m of cable. This
provides the best picture quality.
