following solutions:
• Press the [Color Mode] button on the remote control to try different color
modes for the image and environment.
• Check your video source settings.
• Adjust the available settings in the projector's Image menu for the current
input source, such as Brightness, Contrast, Tint, Color Saturation, and
RGBCMY.
• Make sure you selected the correct Signal Format or EDID setting in the
projector's Signal I/O 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.
• Position the projector close enough to the screen.
• When using multiple projectors, make sure the Light Source Calibration
setting in the projector's Management menu is set to the same option on all
the projectors and that the projectors have been calibrated recently. If
certain projectors are not calibrated recently, the white balance and
brightness level may not match the other projectors.
