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

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.

Diagram: Monitor placed on a table, showing a distance of 100 mm (3.9 inches) from the wall.

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.
  • Standing the monitor panel up vertically may cause the monitor to fall due to the joystick and cause damage or injury. In addition, this may cause the joystick button to malfunction.

How to fix a clamp

1. After positioning the stand on the table, secure it by turning the handle.

For tables without a protrusion:

The table should be less than 75mm (2.9 inches) thick.

Diagram: A clamp securing a monitor stand to a table. Shows a maximum table thickness of 75mm (2.9 inches).

CAUTION

  • Stands that are not fully engaged to the table may allow the monitor to wobble or fall over.
  • Make sure the table is solid and stable enough to fully support installation of the monitor. Tables made of fragile materials such as glass may break.
  • For tables with a protrusion: If the protrusion is located more than 95 mm (3.7 inches) away from the edge of the table, install the monitor only when a flat protrusion is located between 10 mm (0.3 inches) to 75 mm (2.9 inches) from the edge of the table.

Swivel stand

Your monitor mount lets you adjust the monitor viewing angle.

Diagram: Monitor stand showing swivel range of ±335°.

Pivot Feature

The pivot feature allows the monitor to rotate 90° counter-clockwise.

Diagram: Monitor head being rotated 90° counter-clockwise relative to the table.

WARNING

When using the Pivot function, do not rotate the monitor too fast or with excessive force. The table may be scratched by contact with the monitor's head.

Diagram: Four steps illustrating the pivot installation process: 1. Raise monitor to maximum height. 2. Adjust monitor angle. 3. Rotate monitor counter-clockwise. 4. Complete installation by rotating 90°.

Leveling the Screen

If the screen appears crooked to one side after the product has been placed in position, straighten the angle horizontally as follows.

Diagram: Monitor screen tilted and being adjusted to a horizontal position.

Adjusting the Stand Height

1. Make sure to hold and move the monitor with both hands.

Maximum height adjustment: 130.0 mm (5.1 inches).

Diagram: Monitor stand showing the height adjustment range.

WARNING

To avoid injury when adjusting the height, do not put your hands on the stand.

Troubleshooting

NOTE

[SMART ENERGY SAVING]: Energy saving data may differ depending on panel and suppliers. Selecting [High] or [Low] may affect monitor luminance.

Nothing is displayed on the screen.

  • Is the monitor's power cord plugged in? Check if it is correctly plugged into the power outlet.
  • Is the power LED on? Check the power cable connection and press the power button.
  • Is the power on and the power LED displaying white? Check that the connected input is enabled ([Settings] > [Input]).
  • Is the [No Signal] message being displayed? This occurs when the signal cable between the PC and monitor is missing or disconnected. Check the cable and reconnect it.
  • Is the power LED blinking? If the monitor is in sleep 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 [Out of Range] message being displayed? This occurs when signals transferred from the PC (graphics card) are out of the monitor's horizontal or vertical frequency range. Refer to the "PRODUCT SPECIFICATION" section to set the appropriate frequency.

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 flicker. 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. Setting methods may vary by OS; contact the graphics card manufacturer if resolutions are unavailable.

The screen retains an image.

  • Does image sticking occur even when the monitor is turned off? Displaying a still image for a prolonged time may cause screen damage and image retention. Use a screensaver to extend monitor lifetime.
  • Are there spots on the screen? Pixilated spots (red, green, blue, white, or black) may appear on the screen during use. This is normal for an LCD screen and not an error.

Some features are disabled.

  • Are some functions not available when you press the Menu button? The OSD is locked. Disable [OSD Lock] in [General]. Check PC settings and input signal (HDR, No Signal).

No sound from the headphone port.

  • Are images displayed without sound? Make sure headphone port connections are proper. Try increasing volume with the joystick. Set the PC audio output to the monitor.

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

  • Have you installed the display driver? Install the display driver from www.lg.com.
  • Make sure to check if the graphics card supports Plug and Play function.
