Possible Solutions
• Perform monitor self-test.
• Ensure that the video cable connecting the
monitor to the computer is connected properly
and is secure.
• Check for bent or broken pins in the video cable
connector.
• Change the settings of the Preset Modes in the
Color menu OSD depending on the application.
• Adjust R/G/B value under Custom Color in Color
menu OSD.
• Change the Input Color Format to PC RGB or
YPbPr in the Color menu OSD.
• Run the built-in diagnostics.
• Set the screen to turn off after a few minutes
of screen idle time. These can be adjusted in
Windows Power Options or Mac Energy Saver
setting.
• Alternatively, use a dynamically 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 monitor power
cable, plug it back, and then turn on the monitor.
• 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. Connect the signal cable again, 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.
