Mounting on a wall
For proper ventilation, allow a clearance of 10 cm
on each side and from the wall. Detailed
instructions are available from your dealer, see the
optional Tilt Wall Mounting Bracket Installation and
Setup Guide.
If you intend to mount the Monitor set to a wall,
attach Wall mounting interface (optional parts) to
the back of the set.
When you install the Monitor set using the wall
mounting interface (optional parts), attach it
carefully so it will not drop.
1
Please, Use the screw and wall mount interface
in accordance with VESA Standards.
2
If you use screw longer than standard, the
monitor might be damaged internally.
3
If you use improper screw, the product might be
damaged and drop from mounted position. In this
case, LG Electronics is not responsible for it.
