4-Corner Correction Guide

The 4-corner correction feature on Christie Digital Captiva projectors allows you to adjust each corner of the projected image independently, helping to eliminate any shadow gaps or separation lines between adjacent images in a multi-projector setup.

Steps to Perform 4-Corner Correction

  1. Turn on the Projector and Access the Settings Menu

  2. Using the projector's remote control, press the Menu button to open the on-screen settings menu.

  3. Navigate to Geometry Correction

  4. In the settings menu, select Geometry Correction. This option allows you to adjust the shape and position of the projected image.

  5. Select 4-Corner Correction

  6. Within the Geometry Correction options, find and select 4-Corner Correction. This feature enables you to adjust each corner of the image individually.

  7. Adjust Each Corner

  8. Use the arrow keys on the remote control to move the highlighted corner. Adjust the position of each corner until the edges of the projection align seamlessly with adjacent projections.

  9. Make minor adjustments as needed to ensure that there are no visible gaps or overlaps between images.

  10. Save and Exit

  11. Once satisfied with the alignment, save the settings. Some projectors may automatically save, but confirm by checking for a Save or Apply option in the menu.
  12. Exit the settings menu by pressing the Menu button again.
