Solution
• Check that COMPUTER INPUT in the SIGNAL menu is correctly set. (See page 39.)
• Check that the cable connected to the external device isn't broken.
• When comparing images projected by two projectors, tints in the displayed images may be
different because of variation between their optical components. This is not a 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
difference in the range of color reproducibility. This is not a malfunction.
• 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. (See page 73.)
• Some images and texts appear obscured during the keystone adjustment. In such
cases, use the projector without applying the keystone adjustment. (See page 14.)

OFF. (See page 44.)
• In some images such as DVD, noise may appear around the recorded image. In this
case, decrease the setting value of OVER SCAN of the SIGNAL menu. (See page 39.)
• Make adjustment according to "How to adjust the computer image" on page 45.
