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.
