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.
• Verify which DP standard (DP 1.1a or DP 1.4) is

install the latest graphics card driver.
• Some DP 1.1a graphics card cannot support
DP 1.4 monitors. Go to OSD menu, under Input
Source selection, press and hold DP select
joystick
key for 8 sec to change the monitor setting from
