Check if the graphics card's resolution or frequency is within the range allowed by the monitor and set
yy
it to the recommended (optimal) resolution in Control Panel > Display > settings.
Not setting the graphics card to the recommended (optimal) resolution may result in blurred text, a
yy
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
yy
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.
Some graphics cards may not support 2560x1080 resolution. If the resolution cannot be displayed,
yy
contact the manufacturer of your graphics card.
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
yy
Control Panel > Display > Settings > Color Quality.
Does the display color appear
unstable or monochrome?
Check if the signal cable is connected properly. Reconnect the
yy
cable or reinsert the PC's graphics card.
Are there spots on the screen?
When using the monitor, pixilated spots (red, green, blue, white,
yy
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?
Be sure to install the display driver from the display driver CD (or
yy
diskette) that comes with your display. Or, you can also download
the driver from our web site: http://www.lg.com.
Make sure to check if the video card supports Plug&Play function.
yy

Are images displayed using
DisplayPort or HDMI input without
sound?
Try increasing the volume using the button on the monitor.
