Analog Way Di-VentiX II - Manual (Page 60)

In Edge Blending mode, Di-VentiX II can drive 2 video-projectors for horizontal or vertical Soft Edge. Used
as an 8 input switcher.
IMPORTANT: Before doing the following adjustments, make sure the 2 projectors are the same (mark, mo-
del, type) with same lenses. The projector matrices should be imperatively at the same reso-
lution. The parameters of the 2 projectors should be homogenous (color, gamma, lamp life-
time...). The screen projection should be vertical and perpendicular to the projectors to avoid
geometric distortion like bow or keystone. Use only mechanical lens shifts, and avoid using
them in their maximal values. Don’t use wide-angle lenses.
1) Connect your Computer & Video sources to the inputs of the Di-VentiX II and connect the two projec-
tors to the MAIN & PREVIEW outputs.
- Output #1 = Left projector in horizontal SEB configuration & Top projector in vertical SEB confi-
guration.
- Output #2 = Right projector in horizontal SEB configuration & Bottom projector in vertical SEB
configuration.
2) Select the input signal type.
3) Select the output format corresponding to the native matrix of the projectors.
4) Display the centering pattern (Output tab > test pattern > centering).
5) Adjust the test pattern in full screen (matrix) of each projector, with the Auto adjust, position or size
adjustment of the projector. Then align mechanically the projectors to have a covering area between
10 and 20% (of each matrix) and to have the test pattern well aligned one on top of the other. As re-
quired, you can use the burst pattern available in the output tab to adjust your projector.
• Example: Test pattern in horizontal SE configuration.

Projectors well aligned.
 Top and bottom not aligned.
 Too small covering area.
 Edges not paralleled
