Use the table below as a guide.
•
For the maximum projection size, use a 200-type (4:3) depending on the lens performance.
•
As the throw distance and projection size are only accurate to within ±5%, a throw distance adjustment mechanism is
required on the installation platform.

Table: Relationship between screen size and throw distance
When high-intensity projection capabilities are required,
two DLA-M4000s can be stacked in a vertical or horizontal
configuration.
In a vertical stacking configuration, the DLA-
M4000s are stacked one above the other. Using the
power-driven lens shift function, the two projection images
can be superimposed to obtain an image with double the
standard brightness.
In a horizontal stacking configuration, the DLA-
M4000s are placed side by side. The two projection
images are superimposed using the mechanical lens shift
function.
Note:
•
As the two projection images are superimposed,
registration differences appear in the center and
peripheral areas of the screen due to the lens distortion.
Use the center portion of the optical lens to minimize the
registration difference. This difference cannot be
eliminated because it is caused by lens distortion. The
smaller the lens magnification, the less the distortion.
Vertical stacking limit range:
The DLA-M4000s can be stacked within the area from the screen
upper edge to the lower edge.
Note:
•
The data in this table is based on the assumption that two DLA-M4000s are stacked vertically.
When the offset axis of unit A is X% and that of unit B is Y%, X is obtained with Y = 50 to 10 in the formula
Y
1
X = 368/H x 100 (provided that the vertical offset axis of the DLA-M4000 is 0 to 50%).
