Vertical Lens Shift
Simplify installation with vertical lens shift, which provides a wider range of projector placement possibilities. This makes it easier to position the projector in your room and enables a wider range of screen size options.
Four corner correction
Adjust the keystone in both the vertical and horizontal plane. You can individually warp each corner of the image to create a perfectly square image. Ideal for image stacking, uneven walls or where projector placement is awkward and needs to be installed at an angle.
Auto Keystone automatically adjusts the trapezoid effect when the projector is off-axis to create an aligned image*.
*Auto keystone only adjusts the image in the vertical plane.
Ideal for digital signage applications; you can rotate your projector 90 degrees to project a portrait image.
Images can be projected over a 360° range* along the projector’s horizontal axis.
