Correcting automatically
Auto V-Keystone
When the projector detects any movement, for example when it is installed,
moved, or tilted, it automatically corrects vertical keystone distortion. This
function is called Auto V-Keystone.
When the projector remains still for about two seconds after it detects
movement, it displays a screen for adjustment and then automatically
corrects the projected image.
You can use Auto V-Keystone to correct the projected image under the
following conditions.
