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.

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.

• 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.

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.

Troubleshooting

Nothing is displayed on the screen.

• Is the monitor's power cord plugged in? Check if the power cord is correctly plugged into the power outlet. If the monitor is in sleep mode (standby mode), move the mouse, or press any key on the keyboard, to switch the display on. Check if the computer is turned on.
• Is the monitor powered on?
• Check if the input setting is correct. ([Settings] > [Input])
• Is the [The screen is not currently set to the recommended resolution.] message being displayed? This occurs when signals transferred from the PC (graphics card) are out of the recommended horizontal or vertical frequency range of the monitor. Please see the PRODUCT SPECIFICATION section of this manual to set the appropriate frequency.
• Is the [No Signal] message being displayed? This is displayed when the signal cable between the PC and the monitor is missing or disconnected. Check the cable and reconnect it.
• Is the [Out of Range] message being displayed? This occurs when signals transferred from the PC (graphics 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 appropriate frequency.

Do you see an "Unrecognised monitor, Plug and Play (VESA DDC) monitor found" message?

• Have you installed the display driver? Be sure to install the display driver from our web site: http://www.lg.com. Make sure to check if the graphics card supports Plug and Play function.

Screen display is unstable and shaky. / Images displayed on the monitor leave shadow trails.

• Did you select the appropriate resolution? If the selected resolution is HDMI 1080i 60/50 Hz (interlaced), the screen may be flickering. Change the resolution to 1080p or the recommended resolution. Not setting the graphics card to the recommended (optimal) resolution may result in blurred text, a dimmed screen, a truncated display area or misalignment of the display. The setting methods may be different depending on the computer or operating system, and some resolutions may not be available depending on the performance of the graphics card. If this is the case, contact the manufacturer of the computer or graphics card for assistance.
• Are there spots on the screen? When using the monitor, pixilated spots (red, green, blue, white, or black) may appear on the screen. It is not an error, nor is it related to the monitor's performance.

Some features are disabled.

• Are some functions not available when you press the Menu button? The OSD is locked. Disable [OSD Lock] in [General].

No sound from the headset port.

• Are images displayed using DisplayPort or HDMI input without sound? Make sure that the headset port connections are made properly. Try increasing the volume with the joystick. Set the audio output of the PC to the monitor you are using. (The settings may differ depending on the operating system (OS) you use.)
