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.
