2. Edge Blending Adjustment Method
Project a cross-hatch of the projector's test pattern, and determine the image size using
zoom and shift.
One square of the internal cross hatch pattern is 32 pixels on all our DLP projectors.
Matching the overlap with a multiple of this 32p raster makes setup very efficient and is
highly recommended.
By keeping the minimum of 10% of the horizontal resolution there are some "industry
standards" for the overlap size:
128 pixels for XGA (D5700) equal to 4 squares of the internal cross hatch pattern
160 pixels for SXGA (D7700,D10K) equal to 5 squares of the internal cross hatch
pattern.
192 pixels for 1080p (D10K) equal to 6 squares of the internal cross hatch pattern.
Check and correct trapezoidal distortion in the vertical and horizontal directions and vertical
linearity caused by the projector's tilt.
Parallelism of the two projectors is easily checked by projecting a cross-hatch pattern from
each projector and separating the grid lines by a dot in the horizontal and vertical direction.
In the menu, turn on edge blending and the marker, and determine the width of blending. In
this case, the blending width of the two projectors should have the same number (for
example, 128 dots).
The starting point of blending is shown in green and the width in red. Overlap the two
patterns using the lens shift to form a single line in yellow (red + green).
The basic rule of blending is to use the same number, which becomes the range of the
image overlap. Use of a blending width smaller than the overlap width makes the blended
range brighter, while a larger blending width makes the area darker. This technique is used
in a rear projected screen when the brightness is felt to be insufficient.
