Problem
Cause and solution
This is due to color breaking noise that occurs in a DLP system and is not a malfunction.
It occurs because of interference with the screen and isn’t a product malfunction.
Change the screen or readjust the focus of the projector.
Connect the cable’s plug with the external device’s connector firmly.
Keep the projector away from equipment generating interfering radio waves.
When the keystone adjustment is carried out, the image may not be displayed
correctly because of the type of input signal. This isn’t a product malfunction.
In this case, readjust the keystone so that the amount of keystone correction
is as small as possible.
Check that the cable connected to the external device isn’t broken.
This is caused by the computer being used. Contact the manufacturer of your
computer.
Match the output resolution of your computer with the resolution of the projector. For the
method to change the output resolution of the computer, contact the manufacturer
of your computer.
