Upon completion of the AutoCal 3D LUT calibration process, CalMAN automatically loads the optimized
65x65x65 point LUT calibration data into the Dolby monitor. This takes a while.
If you have used the Dolby internal test pattern generator to perform the calibration, power cycle the
Dolby monitor after the LUT finishes loading, to reset the Dolby signal processing.
5. Display Validation section
The Dolby internal test pattern generator does not feed through the 3D calibration LUT, so the internal
patterns cannot be used for calibration validation.
Test Pattern Source Note
The Dolby PRM-4200 has an internal test pattern generator, which can be used to calibrate the Dolby’s
internal 3D LUT.
However, the Dolby internal test patterns have a significant switching delay when each new test pattern
is accessed. Also, the internal test pattern generator does not feed through the 3D calibration LUT, so
the internal Dolby patterns cannot be used to validate the 3D calibration LUT.
For these reasons, you may wish to use another test pattern source, such as the CalMAN Client 3 or a
hardware test pattern generator for both the calibration and the validation.
