Test Images (continued)
“converging” at the same point, the red, green, and blue components
combine exactly to produce white. When the RGB guns are
misaligned, the white lines appear to have “ghosts” or “halos”, or in
extreme cases, separate into individual red, green, and blue lines.
To adjust convergence:
1. Select the Crosshatch test image.
2. Evaluate the image on the associated display device.
3. If the white vertical and horizontal lines appear to have color
edges, adjust the display’s RGB gun controls until the white
lines are aligned and appear to be white.
To adjust display geometry:
1. Select the Crosshatch test image.
2. Observe the display geometry on the associated display for
proper alignment and position. The image should fill the
display and appear centered, with all edges visible.
3. If the horizontal and vertical lines appear to be shifted vertically
or horizontally, the test pattern is not centered, or all edges are
not visible, adjust the display horizontal and vertical controls
until the image is centered and all edges are visible.
