ASSEMBLING AND PREPARING

 CAUTION

 

Always use genuine LG components to ensure safety and product performance.

 

The product warranty will not cover damage or injury caused by the use of unauthorized components.

 

It is recommended that use the supplied components.

 

If you use generic cables not certified by LG, the screen may not display or there may be image noises.

 

Illustrations in this document represent typical procedures, so they may look different from the actual product.

 

Do not apply foreign substances (oils, lubricants, etc.) to the screw parts when assembling the product. (Doing 
so may damage the product.)

 

Applying excessive force when tightening screws may cause damage to the monitor. Damage caused in this 
way will not be covered by the product warranty.

 

Do not carry the monitor upside down by just holding the base. This may cause the monitor to fall off the stand 
and could result in personal injury.

 

When lifting or moving the monitor, do not touch the monitor screen. The force applied to the monitor screen 
may cause damage to it.

 NOTE

 

The components may look different from those illustrated here.
