changing screensaver.
Possible solutions
• Check the Aspect Ratio setting in the
Display menu OSD.
• Reset the monitor to factory settings.
• Turn Off the monitor, unplug the power
cord, plug it back, and then turn On
the monitor.
• The OSD menu may be locked. Press
and hold the Menu/function button
next to the Power button for 4
seconds to unlock (for more
information, see Lock).
• Check the signal source. Ensure the
computer is not in the power saving
mode by moving the mouse or pressing
any key on the keyboard.
• Check whether the signal cable is
plugged in properly. Re-plug the signal
cable if necessary.
• Reset the computer or video player.

ratio) of DVDs, the monitor may display
in full screen.
• Run the built-in diagnostics.
