Performing Rough Image Adjustments

Perform the following operations for all projectors to adjust the position and the shape for rectangular projected images.

Displaying the test pattern makes it easier to adjust the projection position and the shape.

  • For projection position, adjust the location, the angle, and the lens shift.

  • For projection size, adjust the location and the zoom.

  • For image focus, adjust the focus.

  • The projected images are not stable right after turning on the projector. We recommend adjusting the projector at least 30 minutes after you start projecting.

  • We recommend displaying the following test patterns:

    Grayscale, Gray Bars V, Gray Bars H, and White

  • When adjusting the image height with vertical lens shift, adjust it by moving the image from the bottom to the top.

    If you adjust it from the top to the bottom, the image position may move down slightly after adjusting.

  • It is not recommended that you perform geometry correction for the following reasons:

    • Image quality may decline.

    • If the correction value is too large, image calibration may be difficult.
