640x350@70Hz
800x600@60HZ / 75HZ
1280x768@60HZ / 75HZ
- Normally when the primary mode 1440x900 @ 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.
● Memory Recall
After final QC step, we have to erase all saved changes again and restore the factory defaults. You
should do "Memory Recall" again.
● Power Off Monitor
