LG 37LF7700 Owner's Manual page 24

NOTE :
Avoid keeping a fixed image on the TV'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, 60Hz for 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 IN(PC) port of the TV or
the signal cable from the HDMI output port of the
PC to the HDMI/DVI IN 1(DVI) port on the TV.
Connect the audio cable from the PC to the AUDIO
►
IN (RGB/DVI) on the TV. (Audio cables are not
included with the TV).
If using a sound card, adjust PC sound as required.
►
This TV uses a VESA Plug and Play Solution. The
►
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),
►
HDMI (Digital RGB) mode.
If required, adjust the settings for Plug and Play
►
functionality.
If the graphic card on the PC does not output
►
analogue and digital RGB simultaneously, connect
only one of either RGB IN or HDMI/DVI IN 1(DVI) to
display the PC output on the TV.
If the graphic card on the PC does output analogue
►
and digital RGB simultaneously, switch 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 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.
