Check if the power cord is correctly plugged into the power outlet. yy Is the power LED on? Check the power cable connection and press the power button. yy Check that the connected input is enabled (Menu > Quick Settings > yy Input). Is the power on and the power LED displaying white? Is the power LED blinking? Is the OUT OF RANGE message being displayed? Is the No Signal message being displayed? If the monitor is in sleep mode, move the mouse, or press any key on the yy keyboard, to switch the display on. Check if the computer is turned on. yy This occurs when signals transferred from the PC (graphics card) are out yy of the horizontal or vertical frequency range of the monitor. Please see the Product Specification section of this manual to set the appropriate frequency. This is displayed when the signal cable between the PC and the monitor is yy missing or disconnected. Check the cable and reconnect it. The OSD lock message is being displayed. Are some functions not avail-able when you press the Menu button? The OSD is locked. Go to Menu > General and set OSD Lock to Off. yy 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 damage to the yy screen, resulting in the retention of the image. To extend the lifetime of the monitor, use a screensaver. yy 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 yy may be flickering. Change the resolution to 1080P or the recommended resolution. NOTE y y Vertical frequency In order to display an image, the screen must be refreshed dozens of times per second, like a fluorescent lamp. The number of times the screen is refreshed per second is called vertical frequency, or refresh rate, and is represented by Hz. y y Horizontal frequency The time it takes to display one horizontal line is called the horizontal cycle. If 1 is divided by the horizontal interval, the result is the number of horizontal lines displayed per second. This is called horizontal frequency and is represented by kHz. ENG ENGLISH Nothing is displayed on the screen. 24 NOTE ENGLISH ENG Check if the graphics card's resolution or frequency is within the range allowed by the monitor and set it to the yy recommended (optimal) resolution in Control Panel > Display > settings. Not setting the graphics card to the recommended (optimal) resolution may result in blurred text, a dimmed yy 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 yy 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. The display color is abnormal. Does the display appear discol-ored (16 colors)? Set the color to 24 bit (true color) or higher. In Windows, go to Control yy Panel > Display > Settings > Color Quality. Does the display color appear unstable or monochrome? Check if the signal cable is connected properly. Reconnect the cable or yy reinsert the PC's graphics card. Are there spots on the screen? When using the monitor, pixilated spots (red, green, blue, white, or black) yy 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? Be sure to install the display driver from the display driver CD (or diskette) yy that comes with your display. Or, you can also download the driver from our web site: http://www.lg.com.
