What is keystone correction?

Keystone correction is a projector feature that allows you to point the lens toward the wall at an angle and adjust the image so that it displays in a 16:9 aspect ratio. The 4-point keystone correction feature helps you overcome angles from room limitations in a few ways.

The Keystone Correction Quick Adjustment feature is great for correcting large picture imbalances or when the lens needs to be rotated for a more balanced display. The Keystone Correction Fine Adjustment feature adds the extra touch to achieve the ideal image.

How do I manually adjust the keystone correction? 

Point your projector towards the wall at an angle. From there:

  1. Go to Settings, select Projector, Keystone Correction
  2. Begin with Quick Adjustment for large corrections, then use the Fine Adjustment to optimize the viewing area. 

What else should I know about keystone correction? 

It's helpful to know how to Reset the keystone correction. To do this:

  1. On your device, go to Settings, Projector, Keystone Correction.
  2. Navigate using the down button on your remote and select Reset
