Keystone

The keystone effect refers to the situation where the projected image
is noticeably wider at the top / bottom / left / right. It occurs when the
projector is not perpendicular to the screen. The screen automatically
performs keystone correction after the projector moves. Make sure the
keystone pattern is completely visible on the screen to ensure a successful
correction.
• Real-time focus & keystone correction: Your projector adjusts focus
and keystone automatically at startup if enabled. This function will
be performed automatically as well when the projector is moved.
To check/change the auto keystone setting, go to

• Distance from lens to wall: 2 meters

• One-click screen adjustment: Press the
button on the remote
control and the projector will automatically focus the image and adjust
keystone. Make sure the full keystone pattern is displayed on the
