	• Check whether the external device output signals. (Check this especially when the
	external device is a notebook computer.)
	• Check that the cable connected to the external device isn’t defective.
	• Check that the projector is connected to the external device using the correct
	terminals.
	• Check that the connected device is correctly selected as the input source.
	• When an extension cord is being used, replace it with the supplied cable and check
	whether images are projected correctly. If images are projected correctly, use an RGB
	signal ampliﬁer along with the extension cord.

Images are not displayed correctly.

	• When the keystone adjustment is carried out, the image may not be displayed
	correctly depending on 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

	malfunction.
	• When comparing the image projected by this projector with those displayed on the
	television or PC monitor, tints in the displayed images may be different because of
