[Edge Adjustment] (4 Corner Keystone)
(Q. Settings)
[Edge Adjustment] (4 Corner Keystone) adjusts the horizontal and vertical sides of the
projected image if the projector is at an angle and not perpendicular to the screen. This
feature ensures the shape of the projected image is not distorted.
Use this feature only when the projector cannot be set up at the optimal angle. [Edge
Adjustment] may result in a loss of image quality.
• The value range of [Edge Adjustment] is as follows.
- [Top Left] (H: 0 to 100, V: 0 to 100)
- [Top Right] (H: -100 to 0, V: 0 to 100)
- [Bottom Left] (H: 0 to 100, V: -100 to 0)
- [Bottom Right] (H: -100 to 0, V:-100 to 0)
[PJT Mode]
(Q. Settings)

calibration of the screen than the [Auto Keystone].
