Yes. Nebula projectors with Android system support Auto (Vertical ±40°) and Manual (Horizontal ±40°) keystone correction. When you set auto keystone correction to “on”, it could only do vertical keystone correction. For horizontal correction, you will need to turn off auto keystone correction and then manually adjust vertical, horizontal, and quadrilateral keystone correction. 
 

How to turn on/off auto keystone correction?

1. Click &quot;Settings&quot;.
