Test PATTERNS
42. NEEDLES
The
Needles
pattern is a standard needle pulse test. The top half of
the screen is black and the bottom half is white with (2) thin inverse-
brightness lines crossing from top to bottom. This pattern allows for
analysis of the sharpness, blooming and screen distortion issues that
a display might have.
43. OVERSCAN
The
Overscan
pattern provides a quick way to determine how much
overscan, or clipping, is being caused by a display. It consists of (5)
concentric rectangles moving in from the outer edge of the signal. They
are positioned at 0%, 2.5%, 5%, 7.5% and 10% of the screen size.
44. PLUGE (2 VARIATIONS)
The
Pluge
pattern is used to perform the accurate and consistent
brightness and contrast configuration of a display. Typically you will
want to adjust the brightness control of the monitor so that the first bar
is just barely indistinguishable from the background black while the
second bar is still clearly visible. Next you should adjust the contrast
so that all four segments of the greyscale box are clearly visible and
distinguishable. There are (2) variations: Full RGB range (0-255) and
Limited RGB range (16-235).
45. SQUARE H8 (2 VARIATIONS)
The
Square H8
pattern is a full field black & white pattern of squares
dividing the screen horizontally into (8) sections. This pattern is
primarily used to check projector linearity. There are (2) variations:
Normal (white lines, black field) and Inverse (black lines, white field).
46. SQUARE H16 (2 VARIATIONS)
The
Square H16
pattern is a full field black & white pattern of squares
dividing the screen horizontally into (16) sections. This pattern is
primarily used to check projector linearity. There are (2) variations:
Normal (white lines, black field) and Inverse (black lines, white field).
