Troubleshooting
1. The screen is blank.
Be sure the power button has been pressed to turn the monitor on.
Confirm the brightness and contrast settings are set normally
Check if the Indicator Light is flashing, if so, this indicates there is no
signal from your video source
If your source is a notebook or laptop, be sure that its settings are in
mirror mode and the device itself is powered on.
2. The image is out of focus.
Ensure the video signal cable is inserted properly on both ends.
3. The screen is flashing.
Try an alternative power source as the current one causing the issue
may be insufficient or too week.
Ensure devices such as non-shielded speakers, fluorescent lighting, AC
transformers, table fans etc. are away from your screen to avoid
magnetic disturbances.
Press the Exit Key on the monitor to auto adjust the image and apply
optimum settings.
4. The color bleeds or visual effects appear unusual.
If your screen is all red, blue, or any colors disappear, check to see
that the signal cable is properly inserted. A loose connection can
cause a bad signal.
Ty connecting to another video source for comparison.
5. The screen appears to be scrolling or rolling or moving unusually.
Check that your source frequency is within 55-76Hz.
Reconnect and ensure your video source cable is secure.
6. The monitor needs cleaning.
Make sure the monitor has been powered off.
Always use a soft, non-abrasive cloth when cleaning.
Use dry, non-abrasive to gently remove debris or dust.
If necessary, lightly dampen a non-abrasive cloth with water and
gently clean the surface.
Never use alcohol or ammonia-base cleaning solutions.
Never spray liquid directly onto any part of the monitor.
