Check for Secondary Display Modes
Test Signal:
Analog: 640*350@70Hz; 640*480@60/67/72/75/85Hz;
720*400@70Hz; 800*600@56/60/72/75/85Hz;
832*624@75Hz, 1024*768@60/70/72/75/85Hz;
1280*1024@60/75Hz
Digital: 640*350@70Hz; 640*480@60/72/75/85Hz;
720*400@70Hz; 800*600@56/60/72/75/85Hz;
1024*768@60/70/72/75/85Hz; 1152*870@75Hz,
1280*720@60Hz, 1280*1024@60Hz
- Normally when the primary mode 1280*1024@60Hz is well adjusted and
compliant with the specification, the secondary display modes will also 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.
