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 (3 variations)
8×8 24×24 48×48
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: 8×8, 24×24 and 48×48.
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.
