E3 Pro Setup Videos & Instructions

1. Get a clear picture


Place the projector a minimum distance of 4t from the screen/wall.


Auto Keystone & Auto Focus

  • When the projector is center-off and throws a distorted picture, it will perform auto keystone correction to achieve a rectangle picture.
  • The Auto Keystone & Auto Focus feature works, while there are no obstacles in front to block the light from projecting.
  • If the projector doesn't adjust the focus and keystone automatically, elevate it higher or remove obstacles in front.
  • The maximum correct angle is ±40°. If the titled angle of the projector exceeds ±40°, the Auto keystone feature will fail to work



Digital Keystone & Digital Focus

  • Press the focus button on the remote control to do manual Focus.
  • If fixing the projector in a place, use the digital keystone on the projector settings. Get more information on the manual.


Keep the Tof out of dust/fingerprint for better Auto Focus & Auto Keystone. If the Tof gets dirty, clean it gently with a glasses cloth.
