ASSEMBLING AND PREPARING
To install the monitor to a wall, attach a wall mount-
ing bracket (optional) to the back of the monitor.

damaged and drop from mounted position.
In this case, LG Electronics is not responsible
for it.
Installing to a wall
Install the monitor at least 100 mm away from the
wall and leave about 100 mm of space at each
side of the monitor to ensure sufficient ventilation.
Detailed installation instructions can be obtained

manual to install and set up a tilting wall mounting
bracket.
y
Unplug the power cord before moving or in-
stalling the monitor to avoid electric shocks.

slanted wall may result in the monitor falling
off, which could lead to injury. Please use
the genuine LG wall mounting bracket. For
more information, contact your local retail
store or a qualified installer.
y
Applying excessive force when fastening
screws may cause damage to the moni-
tor. Damage caused in this way will not be
covered by the product warranty.
y

that conform to the VESA standard. Dam-
age caused by the use or misuse of inap-
propriate components will not be covered
by the product warranty.
y

This occurs when signals transferred from the PC (video card) are out
of the horizontal or vertical frequency range of the monitor. Please see
the "Product Specification" section of this manual to set the appropri-
ate frequency.
Is the "CHECK SIGNAL CONNEC-
TION" message is displayed?
y
This is displayed when the signal cable between the PC and the moni-

y
Use a screen saver to protect the screen when using the monitor for a
prolonged period of time.
y
Vertical Frequency:
In order to display an image, the screen must be refreshed dozens of times per
second like a fluorescent lamp.
The number of times the screen is refreshed per second is called vertical frequency or refresh rate
and is represented by Hz.
y
Horizontal Frequency:
The time it takes to display one horizontal line is called the horizontal cycle.
The number of horizontal lines displayed in one second can be calculated by dividing one by the hori-
zontal cycle. This is called horizontal frequency and is represented by kHz.
NOTE
The screen is flickering.
Did you select the recommended
resolution?
y
If the selected resolution is HDMI 1080i 60/50 Hz, the screen
may be flickering. Change the resolution to the recommended
