About geometric correction

This menu allows you to configure the geometric shape of the projected image. Do this to reshape the image for different projection surfaces.

Warp control

Configure warp settings.

• Basic: Configure basic settings, such as keystone, pincushion, and 4-corner.
• Advanced: Configure advanced settings, such as grid points, warp inner, warp sharpness, and more.

Basic Warp

Configure basic warp settings.

• Keystone: Keystone function is used to adjust the images in asymmetric rectangle shape.

  • H. Keystone : Adjust the left and right side of the projected image to make it an even rectangle. It is used for the images with unequal left and right sides.

    

  • V. Keystone : Adjust the top and bottom side of the projected image to make it an even rectangle. It is used for the images with unequal top and bottom sides.

    

• Pincushion: Pincushion function is used to adjust the image with barrel or pincushion distortion.

  • Horizontal: Correct the projected image with horizontal barrel or pincushion distortion

    

  • Vertical: Correct the projected image with vertical barrel or pincushion distortion.

    

• 4 - corner : Reshape the image by moving the 4 corners of the image to have it fit a specific projection surface.

  

Advanced Warp

Configure advanced warp settings.

• Grid Points: Set the grid points of warp pattern.

• Warp Inner: Enable or disable warp inner control.

  Note: the warp inner does not support 2x2 grid points.

• Warp Sharpness: When the grid lines are warped from straight into curve, the grid lines will be distorted and become jagged. To avoid the line jagged are too obvious, users can adjust the warp sharpness to blur or sharpen the edge of the images.
• Grid Color: Select a grid color for warp and blend pattern.
• Grid Background: Select the grid background.

• Blend Setting: Configure the blend settings directly on the projector to merge two or more adjacent images into one larger and seamless image.

  • Blend Width: Set the blend pattern width.
  • Overlap Grid Number: Set the blend overlap grid number.
  • Gamma: Set the gamma value of the blend area to adjust the curvature of the blending effect.
