The symptom occurs because the projector is not level with the screen, and you need to adjust the keystone.
What is the Keystone function?
The Keystone function is a correction feature that adjusts the projected screen to fit the shape of the
screen. It prevents the screen from appearing trapezoidal when the projection angle between the screen
and the projector does not form a right angle.
As the correction level increases, the picture quality on the screen may deteriorate. Therefore, it is recommended that you first physically adjust the projector's position as much as possible by moving it up, down, left, and right and then use the keystone correction function.
