Solutions When Automatic Adjustments Are Not Applied Correctly - Epson EB-L770U User Manual

• Check your video source settings.
• Adjust the available settings on the Image menu for the current input source, such as Brightness,
Contrast, Tint, Color Saturation, and RGBCMY. RGBCMY should be set by a professional color
calibrator using specialized color calibration tools in a controlled lighting environment.
• Make sure you selected the correct Video Range or EDID setting on the Signal menu, if available for
your image source.
• Make sure all the cables are securely connected to the projector and your video device. If you
connected long cables, try connecting shorter cables.
• Make sure the Brightness Settings options in the Settings menu are set correctly.
• Position the projector close enough to the screen.
• When using multiple projectors, make sure Light Source Calibration in the Reset menu is set
correctly in all of the projectors. If light source calibration is performed only in some of the projectors,
the white balance and the brightness level of the projected image may differ between the projectors.

Solutions When Automatic Adjustments are not Applied Correctly

If you have problems with automatic adjustments not being applied correctly, try the following solutions:
• Wait 20 minutes after turning on the projector before performing the automatic adjustments. This
allows the projector temperature to stabilize.
• Make sure there is no dirt or obstacles around the optional external camera.
• Make sure the cable for the optional external camera is securely connected to the projector.
• The optional external camera may be defective. Contact Epson for help.
• If projecting from a analog input source, the changing color and brightness of the image may cause
automatic adjustments to not be applied correctly.
• Make sure that a powerful spotlight or source of strong natural light is not shining into the projection
environment and interfering with automatic adjustments.
