Test PATTERNS
19. CROSS HATCH 8 (2 VARIATIONS)
The
Cross Hatch 8
pattern is a full field black & white pattern of crossing vertical and
horizontal lines dividing the screen into (8) sections in each direction. This pattern is
primarily used to check for color convergence and pincushion issues in projectors. There
are (2) variations: Normal (white lines, black field) and Inverse (black lines, white field).
20. CROSS HATCH 16 (2 VARIATIONS)
The
Cross Hatch 16
pattern is a full field black & white pattern of crossing vertical and
horizontal lines dividing the screen into (16) sections in each direction. This pattern is
primarily used to check for color convergence and pincushion issues in projectors. There
are (2) variations: Normal (white lines, black field) and Inverse (black lines, white field).
21. CROSS HATCH 32 (2 VARIATIONS)
The
Cross Hatch 32
pattern is a full field black & white pattern of crossing vertical and
horizontal lines dividing the screen into (32) sections in each direction. This pattern is
primarily used to check for color convergence and pincushion issues in projectors. There
are (2) variations: Normal (white lines, black field) and Inverse (black lines, white field).
22. DIAGONAL 1
The
Diagonal 1
pattern is a set of (3) diagonal colored lines (red,
white and blue) within a white square in the middle of the screen. This
pattern is used to check for distortion and alignment issues in the
center of the screen.
23. DIAGONAL 2
The
Diagonal 2
pattern is (2) diagonal lines that travel from the
corners to the exact center of the display. This can be used to check
for alignment and geometry issues, particularly with projectors. The
outer border of the screen also has a white outline to verify that the full
image is being displayed.
