NOTE: To make sure that an input source is not the cause of a problem for a composite source, turn the ter- mination switch off and connect a composite monitor to the composite input Loop input. For a R,G,B input source, turn the three termination switches off and connect a R,G,B monitor to the R,G,B input Loop input.
To make sure that a projector is not the cause of a problem, connect a VGA monitor to the 15pin VGA output connector and check the display to see if it is correct and if the projector is the problem. If the monitor display shows the same problem as the projector display, then the line doubler has a problem and you should contact our Technical Support Department.
