Fortunately, the P1i is perhaps the easiest projector in this price range to align with your wall or screen. It has Anker’s Smart Instant Setup that automatically adjusts the autofocus, keystone correction, screen fit and obstacle avoidance. For my 120-inch roll down screen, I just had to set the P1i about 11 feet from the wall, make sure it was fairly level and then tilt the stand so it pointed at the screen. Then, I just ran the smart setup which instantly gave me a correctly set-up image.
