Test PATTERNS
1. BORDER
The
Border
pattern presents (4) equal-sized squares dividing the
screen into (4) quadrants, forming a central white cross, with red,
green, blue and white inner squares. Ideal for testing screen boundary,
alignment and pincushion issues. All lines should be straight, and edge
transitions should be sharp.
2. CHECKERBOARD
The
Checkerboard
pattern displays a repeating black and white checkerboard image.
This is ideal for checking the alignment and corner convergence of TVs or monitors.
Bandwidth can be checked by observing the vertical transitions. Transitions from black
to white should be sharp. There are (3) variations: 8x8, 24x24 and 48x48.
3. CIRCLE 1
The
Circle 1
pattern provides a single white circle in the middle with a
white cross and a white outer border line. This pattern is designed for
quickly confirming that the geometry of the scene is correct and that
the full source is being displayed, edge to edge.
4. CIRCLE 4
The
Circle 4
pattern provides (4) smaller white circles in each of the
(4) corners of the screen. This pattern can help confirm that the display
is maintaining correct geometry at the edges of the screen.
5. BLACK
6. BLUE
7. CYAN
8. GREEN
9. MAGENTA
10. RED
11. WHITE
12. YELLOW
These patterns are full screen purity tests offering (8)
different full field patterns:
Black, Blue, Cyan, Green,
Magenta, Red, White, Yellow.
The color patterns should
display an even distribution of brightness and consistent
color tone across the screen. The 100% white pattern
should display evenly across the screen and not cause
the display’s overall brightness to lower, or for the image
to become instable. The black pattern will give a good
idea of the display’s true minimum brightness capability
and is helpful for setting the viewing room lighting levels.
