How is the Poseidon E40 keystone correction？🔥🔥🔥🔥

The Poseidon E40 supports Auto keystone, Vertical correction, Horizontal correction, and Remote Corner Correction.

Suggestion: When projecting from the front, a horizontal elevation angle of the projector within 20° will ensure a clearer image. [Adjust the angle to support up to 30°, with a recommended optimal angle of 20° for clearer images.]

Auto Keystone：

Press the button to go to the projector home menu, [Settings]->[Projection Settings]->[Keystone Settings]->[Turn on Auto Keystone]
When the projector image is distorted, it will perform auto keystone correction to restore the image to a rectangle. If you find the auto keystone correction does not work as well as before, follow the instructions below to optimize it.

Select [Calibration Settings] and adjust the projector for the correct image.

Vertical / Horizontal correction:
1. When fixing your projector in a place use Vertical / Horizontal correction.
Press the button to go to the projector home menu, and select [Settings] -> [Projection Settings] -> [Keystone Settings] ->Turn off Auto keystone correction and go back to the previous menu.
2. Select [Projection Settings]->[Vertical Correction] / [Horizontal Correction], and press the left or right button on the remote control to adjust.

Manual Corner Correction:
If the projected image is stretched or distorted along both axes due to the angle of the projection, press the button to go to the projector home menu, and select [Settings]->[Projection Settings]->[Corner Correction], choose the corner you want and press left or right button on the remote control to adjust.

Keystone Correction Reset:
