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

- 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.
