Correcting Image Shape with the Horizontal Keystone Slider

You can use the projector's horizontal keystone slider (EX5280/EX9230/EX7280/EX9240) to correct the shape of an image that is unevenly rectangular horizontally, such as when the projector is placed to the side of the projection area.
Note: To provide the best possible image quality, adjust the projector's position to correct the image shape. If this isn't possible, use the horizontal keystone slider on the projector to correct the image shape.
  1. Turn on the projector and display an image.
    Note: You can display a pattern to aid in adjusting the projected image using the Settings menu.
  2. Adjust the slider until the image is evenly rectangular.


    After correction, your image is slightly smaller.
