The image is not rectangular. What should I do?

• Try the following:
  • Place the projector directly in front of the center of the screen, facing it squarely, if possible.
  • If you adjusted the projector height using the projector feet, press the keystone buttons on the projector to adjust the image shape.
  • Turn on automatic keystone adjustments using the projector's menus.
  • Press the Screen Fit button (PowerLite 1775W) and adjust the image shape using the on-screen display.
  • Adjust the Quick Corner setting to correct the image shape.
