How do 2D keystone positions and values correlate to the image distortion adjustment?


2D keystone position and values correlate to the distortion adjustment mainly in the following two ways:
(1) When the zoom ratio changes, the position of projector changes in sagittal axis direction.
(2) The adjustment setting of 2D keystone is one value for one degree. When 2D keystone is adjusted by one degree, the keystone value on OSD will be plus/minus (+/-) 1.
The distorted images can be adjusted either automatically, or manually by pressing the arrow keys on the projector or remote control.
