NOTE
• 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.
• 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.
• Check if the graphics card's resolution or frequency is within the range allowed by the monitor and in Windows set it to the recommended (optimal) resolution in Control Panel > Display > Settings. (May differ depending on your
operating system (OS).)
• Not setting the video 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.
• Normal graphics cards do not support 1920 x 1080 resolution. If the resolution cannot be displayed, contact the manufacturer of your graphics card.

The image is displayed abnormally.
Does the screen area appear abnormal?
Do you see vertical lines on the screen?
Does the screen display horizontal noise, or does the

• Set the number of colours to 24 bits (true colours) or higher: In Windows Control Panel > Display > Settings > Colour Quality (May differ depending on your operating
system.)
• Check if the signal cable is connected properly. Reconnect the cable or reinsert the PC's graphics 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.
Install the enclosed monitor driver which is provided with the monitor or go to LG Electronics homepage ( www.lg.com ) to download and install the monitor driver.
•
• Check whether the plug & play function is supported by referring to the graphics card user manual.
• If you want to automatically configure display images to optimal settings, enter the [Auto Configuration] function and select [Yes].
