Edge Blending Setup Procedures
Note:
This manual used 1x2 edge blending as an example.
1.
Set up your projectors
Make sure the projectors cover the whole screen evenly and proper overlap is formed.
2.
Connect DS2 to projectors and other devices
Ensure the ‘
LAN
’ port on DS2 is connected, not the ‘
RS232
’ port
3.
Find
the edge blending overlap positions on screen
a.
Calculate the overlap width using the equation is:
𝑊 =
L∗P
T
W: Edge blending overlap width
L: Length of the projection screen
T: total pixels of the projection
P: edge blending area total pixels
b.
So, the right edge of projector A is
L
2
+
W
2
and the left edge of projector B is
L
2
−
W
2
c.
Example:
i.
L is 300cm
ii.
Project A and B output resolution is 1920 x 1080,
iii.
Edge blending area pixels is 240 pixels
iv.
So T = (1920*2-240) =3600 pixels
v.
W = (300*240)/3600 = 20cm
Therefore, the edge positions for project B A is 0 at left and 160cm at right. The
edge positions for projector B is 140cm and 300cm at right.
