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.
• Check whether the OSD menu is
locked. If yes, move and hold the
joystick up/down/left/right for 4
seconds to unlock (for more
information, see Lock).
• Check the signal source. Ensure the
computer is not in the standby 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.
• Due to different video formats
(aspect ratio) of DVDs, the monitor
may display in full screen.
• Run the built-in diagnostics.
