NP410W and +/−20 degrees on the NP610S/NP510WS.
The maximum range of keystone correction may be lower depending on the signal or aspect ratio selection.
The range of keystone correction is not the maximum tilt angle of projector.
• The Auto Keystone correction will take effect in 2 seconds after changing the projection angle during projection.
• The left and right (horizontal) keystone correction is not available.
Place the projector so that the lens surface is parallel to the screen.
The rear feet of the projector can be adjusted to level the projector.
• Using keystone correction can cause the image to be slightly blurred because the correction is made electronically.
TIP: If you have one of the following conditions, the projector’s Auto Keystone may not be performed correctly.
• The screen is tilted
• The room temperature is too high or too low
• The optical zoom is maximized or minimized
