select Control Panel -> Display -> Settings -> Color Quality.
• Check the connection of signal cable and connect it properly. Or,
pull out and insert the video card in the PC again.
• The screen may display a few pixel spots (red, green, blue, white
and black) during operation. This is caused by the inherent
characteristics of LCD panels. This is not a fault and unrelated to
the monitor's performance.
• Visit the homepage of LG Electronics (http://www.lg.com) to
download and install the driver.
• Check the user's manual for the video card and see if it fully sup-
ports the Plug and Play function.
