Automatic Keystone Adjustment
Automatic Keystone adjustment is enabled through a level-
sensor on the projector. As the projector is tilted the image is
automatically scaled to match the angle / degree of tilt. This
feature is turned “on” from the factory.
Manual Keystone Adjustment
Users can choose to adjust the keystone themselves to match
circumstances where the automatic keystone adjustment is
ill-suited. This can be achieved by selecting “manual” in the
Keystone adjustment submenu found in the OSD menu.
No Keystone Adjustment
Keystone adjustment can be turned off through the Keystone
submenu.
