Welcome to the forum. I would suggest that you post these questions in the regular thread. No need to start a new thread with every question.
The projector is not set up correctly. You don't say how it is mounted but it is not even with the screen. That is the reason for the test pattern. Try moving the projector slightly on each side from front to back. You may also want to measure the distance from the projector on each side. Being off by a slight amount will cause this issue.
