Appendix A – VirtualForge Test Patterns
The VirtualForge reference software pattern generator provides any RGB color in a full field or window
pattern, as requested by CalMAN for display measurement and calibration (16.78 million 8-bit colors or
1.07 billion 10-bit colors).
VirtualForge also provides specialty test patterns for visual display performance testing or for optimizing
the adjustment of display Picture controls (contrast, brightness, etc.). When CalMAN is connected to the
VirtualForge software generator, these patterns are available from CalMAN’s specialty pattern icon, as
shown below.
