1.5.13 Check for Secondary Display Modes
Test Signal:
Analog: 640*350@70Hz; 640*480@60HZ
720*400@70Hz; 800*600@60HZ/70HZ/75HZ
832*624@75Hz, 1024*768@60HZ/70HZ/75HZ
1280*1024@60/75Hz
Digital: 640*350@70Hz; 640*480@60HZ
720*400@70Hz; 800*600@60HZ/70HZ/75HZ
1024*768@60/70/72/75; 1152*870@75Hz,
1280*1024@60Hz/75HZ
- Normally when the primary mode 1280*1024@60Hz is well adjusted and compliant
with the specification, the secondary display modes will be great possible to be compliant
with the spec. But we still have to check with the general test pattern to make sure every
secondary is compliant with the specification.
