Section 4: OPERATION
• Color wheel Index (3x): Set Color wheel index to Speed 3X. This setting
only needs to be used when the Main Board is changed, and should be
adjusted to optimize picture quality.
• Error log: Show the projector error log for debug.
• Mode Adjustment: Fine tune the H and V start position for a signal in the
EDID timing table and record the values in the system to override the timing
table. The settings must be "Saved to Record" before exiting the menu, or
they will be lost. To revert to original timing table settings, each setting must
be manually cleared. Factory Defaults will not clear these override settings.
• High temperature warning: Show the warning message when the ambient
temperature is over 35°C.
• DA Mode: DA mode helps user to fine tune the DA offset if it is biased
according to serious vibration, heavy dust or improper operation.
1 DA offset
Manually adjust the DA offset to get the correct aperture. User can
change the value of slide bar and observe the projecting image.
Find the value corresponding to the maximum brightness.
Recommended value would be within 10~16.
2 DA calibration
This is the general switch to enable the advanced DA offset calibration.
Enable the advanced algorithm to overcome the DA problems.
3 DA check
Trigger one shot advanced DA offset calibration right away to get the
maximum brightness step.
4 Always calibration
With "DA calibration" being enable, operate the advanced DA offset
calibration automatically in every startup.
This item can be automatically checked if DA failure has ever been
detected.
