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 unauthorised components.
• It is recommended that use the supplied components.
• The product figures and screen displays used in this manual are examples to help consumers use the product  and may differ 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.
• For wave pattern on appearance, unlike the general method of coating, it’s applied to added glittering material in raw material. With no peeled-off appearance, it has good durability. Please use it with confidence because there is no problem in using the product at all.

NOTE

Installing
Moving and Lifting the Monitor
When moving or lifting the monitor, follow these instructions to prevent the monitor from being scratched or damaged and to ensure safe transportation, regardless of its shape or size.

• Place the monitor in the original box or packing material before attempting to move it.
• Before moving or lifting the monitor, disconnect the power cord and all other cables.
• Hold the bottom and side of the monitor frame firmly. Do not hold the panel itself.
• When holding the monitor, the screen should face away from you to prevent it from being scratched.
• When transporting the monitor, do not expose the monitor to shock or excessive vibration.
• When moving the monitor, keep it upright and never turn the monitor on its side or tilt it sideways.

CAUTION

• Avoid touching the monitor screen as much as possible.
  – This may result in damage to the screen or some of the pixels used to create images.

• If you use the monitor panel without the stand base, its power button may cause the monitor to become unstable and fall, resulting in damage to the monitor or human injury. In addition, this may cause the power button to malfunction.

Installing on a Table

• Lift the monitor and place it on the table in an upright position. Place the monitor at least 100 mm away from the wall to ensure sufficient ventilation.

CAUTION

• Unplug the power cord before moving or installing the monitor. There is risk of electric shock.
• Make sure to use the power cord that is provided in the product package and connect it to a grounded power outlet. (Depending on country)

Using the Kensington Lock
For more information on installation and usage, refer to the Kensington lock owner’s manual or visit the website at http://www.kensington.com.
Connect the monitor to a table using the Kensington security system cable. NOTE

• The Kensington security system is optional. You can obtain optional accessories from most electronics stores.

Installing on the Wall
This monitor meets the specifications for the wall mount plate or other compatible devices.
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 from your local retail store. Alternatively, please refer to the manual for how to install and set up a tilting wall mounting bracket. Installing the Wall Mount Plate
To install the monitor to a wall, attach a wall mounting bracket (optional) to the back of the monitor.
Make sure that the wall mounting bracket is securely fixed to the monitor and to the wall.

NOTE

• Use the screws specified by VESA standards.
• The wall mount kit includes the installation guide and all necessary parts.
• The wall mounting bracket is optional. You can obtain optional accessories from your local dealer.
• The length of the screw may differ for each wall mounting bracket. If you use screws longer than the standard length, it may damage the inside of the product.
• For more information, please refer to the user manual for the wall mounting bracket.
• Be careful not to apply too much force while mounting the wall mount plate as it may cause damage to the screen.
• Remove the stand before installing the monitor on a wall mount by performing the stand attachment in reverse.

CAUTION

• Unplug the power cord before moving or installing the monitor to avoid electric shock.
• Installing the monitor on the ceiling or on a slanted wall may result in the monitor falling off, which could lead to injury. Use an authorised LG wall mount and contact the local dealer or qualified personnel.
• To prevent injury, this apparatus must be securely attached to the wall in accordance with the installation instructions.
• 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.
• Use the wall mounting bracket and screws that conform to VESA standards. Damage caused by the use or misuse of inappropriate components will not be covered by the product warranty.
• When measured from the back of the monitor, the length of each installed screw must be 8 mm or less.

Important Information for Preventing Image Retention

Unlike regular LED/LCD monitors, pixels in the OLED monitors emit light on their own, achieving a perfect black and creating clear images without blurring of light.
Image retention does not occur in normal use of the product, but can occur if the same screen is watched for a long time. Built-in features are available to protect the screen from possible image retention.
If a static image persists on the screen, the screen saver will automatically lower the full screen brightness, and the screen will turn off automatically after a certain period of time. When an image change is detected, the brightness is automatically restored to its original state. This is not a malfunction of the product.
Examples of Images that may Cause Image Retention

• Static images or images containing objects/information that are constantly visible in a fixed position on the screen (e.g., icons on the desktop, fixed windows such as menus, or logos while watching broadcasts, etc.)
• Fixed menu/icon on a game console or set-top box
• Fixed menu on the top corner of the web browser

Recommendations For Preventing Image Retention

• You can prevent image retention using monitor menu settings. (Go to [Settings] > [General] > [OLED Screen Move] / [OLED Screen Saver] / [OLED Image Cleaning])

Safety precautions for prolonged use
Due to the unique properties of OLED panels, the brightness may be reduced with prolonged use. Reduced brightness is permanent.
In addition, repeated use in conditions such as high temperature and high humidity or still images/high luminance may result in afterimages, image blurring, or screen malfunction.
