25 ENEGNLGISH NOTE yyCheck if the graphics card's resolution or frequency is within the range allowed by the monitor and set it to the recommended (optimal) resolution in Control Panel > Display > settings. yyNot 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. yyThe 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. yySome graphics cards may not support 2560 × 1080 resolution. If the resolution cannot be displayed, contact the manufacturer of your graphics card. The display color is abnormal. Does the display appear discol-ored (16 colors)? Does the display color appear unstable or monochrome? Are there spots on the screen? yySet the color to 24 bit (true color) or higher. In Windows, go to Con-trol Panel > Display > Settings > Color Quality. yyCheck if the signal cable is connected properly. Reconnect the cable or reinsert the PC's graphics card. yyWhen 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&Play (VESA DDC) monitor found" message? Have you installed the display driver? yyBe sure to install the display driver from the display driver CD (or diskette) that comes with your display. Or, you can also download the driver from our web site: http://www.lg.com. yyMake sure to check if the video card supports Plug&Play function.
