Corner Adjustment
Projected images from multiple projectors used in overlapping projection must be precisely repositioned. Positions of each corner in the blending area can be aligned with the blending area of the reference projector.
1 On the reference projector, configure keystone (P145) and edge-blending settings, and then set the edge-blending markers to [On].

2 Select [Install settings] > [Professional settings] > [Edge blending] > [Adjust] > [Corner adjustment].

3 Select a point to adjust, and move it so that the image as a whole looks symmetrical.


4 As you watch the projected images, fine-tune markers of the projector you are adjusting so that they overlap the reference projector markers as much as possible.

Adjust positions of each of the four corners in the overlapping area.
Correcting the position of one point will also move the point on the opposite side of the overlapping area, so that the screen as a whole is corrected.

5 Set the reference projector’s edge-blending markers to [Off]

• First, complete [Side] adjustment 
• Sides set to an edge-blending width of 12 or more can be adjusted when [Keystone] is set to [Corner adjustment] and the aspect ratio is [16:10].
• To reset adjustment, use [Keystone]
• A small edge-blending width may limit the amount of adjustment available
