'Sync Mode' provide different methods for different types of display refresh operation.
Frequency mode is best suited to displays that have an inherent low-frequency flicker, typically less than 150Hz, as with CRT displays and some LCD displays with CCFL backlights. A possible restriction is that at extreme low-light levels precision may be reduced, unless the integration time is set to a high value.
(Frequency mode measures the number of flicker pulses over the set Integration Time, and normalises the result by the integration time to attain the flicker frequency.)
Period mode is best suited to displays that do not flicker, or flicker at a very high frequency, above than 5000Hz. On such displays this mode will have higher precision at extreme low-light levels.
(Period mode measures the time between a set number of flicker pulses, within the set Integration Time, and divides the measure time by the number of flicker pulses to attain the flicker frequency.)
BURST mode is an alternative mode aimed at displays with flicker that changes with light output levels, or 'pulse', as with PWM (Pulse Width Modulation) on displays such as Plasmas, OLEDs and DLP projectors.
Note: BURST mode has been depreciated with the introduction of AIO mode on RevB versions of the i1D3, but may still be preferable on some displays with variable flicker/dithering, and for use on RevA probes.
AIO mode is a combination of Frequency and Period modes, and has the capability to synchronize with all displays of any given flicker/frequency, and is the suggested mode for most display types.
Note: AIO mode is only implemented in the later RevB versions of the i1D3 probe.
As with any set of 'rules', in the real world nothing is written in stone. And with displays that use PWM, or other frequency/flicker based technologies, there is potential for the alternative modes Frequency/Period/Burst modes to provide enhanced precision in low-light levels, if the integration time is set to an extended enough duration.
Note: When the i1D3 attempts to measure levels below its minimum capability it may return measurement data that is 'generic', depending on the Sync mode selected. This tends to be more prevalent in Frequency mode.
Intelligent Integration set a nits value below which the i1D3 will perform a second, third, fourth, etc. reading, with increasing integration times, up to the maximum integration time of 6 seconds. The readings will stop as soon as a stable and valid reading is achieved. If no valid and stable reading is achieved a 'zero' value will be returned, enabling LightSpace to intelligently calculate a replacement value when generating a calibration LUT.
With the addition of Intelligent Integration, for many display types the use of Frequency Mode may prove to provide the best possible measurements, as the integration time will be extended below the set Nits level, overcoming the inherent limitation with Frequency Mode when used without Intelligent Integration. But be aware Frequency mode is NOT suitable for all display types - OLEDs for example.
