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.

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.
