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.
• 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.

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.
• Does image sticking occur even when the monitor is turned off? Displaying a still image for a prolonged time may cause damage to the screen, resulting in the retention of the image. To extend the lifetime of the monitor, use a screensaver.
• Are there spots on the screen? When using the monitor, pixilated spots (red, green, blue, white, or black) may appear on the screen. This is normal for an LCD 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.

Do you see an "Unrecognized 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.

No sound from the headphone port.

• Are images displayed without sound? Make sure that the headphone 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.)
