Test Signal:

Analog: 640*350@70Hz; 640*400@60Hz;640*480@50/60/67/72/75/85Hz;

720*400@70Hz, 800*600@56/60/72/75/85Hz;

832*624@75Hz, 1024*768@50/60/70/72/75/85Hz;

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.
