ENGLISH The display color is abnormal. Does the display appear discolored (16 colors)? Does the display color appear unstable or monochrome? Are there spots on the screen? •• Set the color to 24 bit (true color) or higher. In Windows, go to Control Panel > Display > Settings > Color Quality. (The settings may differ depending on the operating system (OS) you use.) •• Check if the signal cable is connected properly. Reconnect the cable or reinsert the PC's graphic card. •• 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. 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 graphic card supports Plug and Play function. No sound from the headphone port. Are images displayed using DP (DisplayPort) or HDMI input 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. On Microsoft Windows, go to Control Panel > Hardware and Sound > Sound > set the Monitor as default device. (The settings may differ depending on the operating system (OS) you use.) 26
