Are image signals being output from the connected computer or 
video equipment?

Note-type and liquid crystal type computers must output image 
signals to the projector.
Image signals are not output externally simply because they are 
output to the LCD screen under normal conditions, so the setting 
must be switched to external output.
There are models for which image signals are not output to the LCD 
screen when output externally.
