Screen Problems

First of all, perform a
check any abnormalities in the projector.
The screen shakes after the momentary appearance of vertical/horizontal lines
and net pattern.
• Stop using items such as wireless telephones, hairdryers, electrical drills etc.
The problem is caused by high-frequency electronic devices such as another
projector or strong electromagnetic sources.
The screen is blank or the image is blurred when an HDMI cable is used.
•
Check that the HDMI® cable meets the required standards. If it is not a certified
HDMI® cable, the screen may flicker or may not display anything.
•
Check that the cable is properly connected. Improper connection may cause
screen flicker.
It does not work when I connect a USB device.
• Check that the USB and USB cable versions are 2.0 or higher.
