Home Support Projectors PowerLite Series Epson PowerLite L770U

I see a color cast over the projected image. What should I do?

  • Try the following:

    • Make sure you are projecting onto a white wall. Projecting onto walls of other colors will impact the overall color cast of the projected image.

      Note: Use of a projector screen is recommended.

    • If you are using an HDMI connection, make sure the cable is securely connected to the projector and video source. If that does not help, try using a different cable.
    • If you are using a HDMI cable longer than 24 feet, try using a 6-foot cable. Connect the cable directly from the source device to the projector. Should the image quality improve, try using a HDMI cable designed for long runs, like a fiber optic HDMI cable.

    • Try changing the color mode setting on the projector. See the table below for the Color Mode options.

    You can set the projector to use these Color Modes, depending on the input source you are using:

    Color Mode Description
    Dynamic Best for projecting in a bright room
    Presentation Best for color presentations in a bright room
    Natural Best for projecting still pictures such as photos
    Cinema Best for movies projected in a dark room
    BT.709 Best for watching digital TV or Blu-ray discs; produces images that conform to the ITU-R BT.709 standard
    DICOM SIM Best for projecting X-ray photographs and other medical images
    Multi-Projection Best for projecting from multiple projectors (reduces the color tone difference between images)

    Note: The DICOM SIM Color Mode is for reference purposes only and should not be used to make medical diagnoses.
