Troubleshooting

• Change the Response Time in the Display OSD to Normal,
or Fast depending on your application and usage.

• Check the Aspect Ratio setting in the Display settings
OSD.
• Reset the monitor to Factory Settings (Factory Reset).
• Turn Off the monitor, unplug the power cord, plug it back,
