Many Epson projector beginners may come across a not rectangular image when they set up their projector.
How to fix this problem?
If the projected image is not evenly rectangular, you can try the following solutions.
If the projector is not mounted on the wall or ceiling, you can place it directly in front of the center of the screen, facing it squarely, if possible.
Adjust the image shape using the Geometry Correction menu settings.
