Check these items
• Eliminate the use of video cable extensions and/or video switch boxes.
• Check that all plugs are firmly seated in their sockets.

the screen to the edges.
• Adjust the geometry (page 11).
• Select MOIRE ADJUST and adjust the moire cancellation effect (page 12).
xProblems caused by the connected computer or other equipment
• Change your desktop pattern.
• Degauss the monitor* (page 12). If you place equipment that generates a magnetic field,
such as a speaker, near the monitor, or if you change the direction the monitor faces, color
may lose uniformity.

• Adjust the convergence (page 11).
• If the control lock is set to ON, set it to OFF (page 12).
• Check that the appropriate USB connectors are securely connected (page 8).
• Check that the 1 (power) switch is in the "on" position. Then reconnect the USB cable to
the monitor.
xProblems caused by the connected computer or other equipment
• Check that the power of any self-powered USB compliant peripheral devices is "on."
• Install the latest version of the device driver on your computer. Contact your device's
manufacturer for information about the appropriate device driver.
• If your USB compliant keyboard or mouse does not function, connect them directly to
your computer, reboot your computer, and make any necessary adjustments to the USB
settings. Then reconnect the keyboard or mouse to the monitor. If you connect a keyboard
or mouse to the USB connectors and then boot your computer for the first time, the
peripheral devices may not function.
• This is the sound of the auto-degauss cycle. When the power is turned on, the monitor is
automatically degaussed for five seconds.
