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.
All Modes Reset
After final QC step, we have to erase all saved changes again and restore the
factory defaults. You should do “All Mode Reset” again.
Power Off Monitor
Turn off the monitor by pressing “Power” button.
