If you are unable to adjust the static iris and would like to use dynamic iris adjustment, please note the following:

The dynamic iris function detects both ambient light and the content being played. When the projector starts up or when the Iris setting is switched to "Auto", the system checks ambient light changes three times within the first three minutes to calibrate the iris for optimal brightness according to the current ambient light. Of these three calibrations, approximately 30% occur within 2–3.5 seconds, and the remaining 70% within about 20 seconds. This timing is primarily affected by the CPU utilization of the GTV chipset, leading to dynamic adjustment intervals.

After these three checks, the calibration process stops until the next startup

or the iris setting is changed to "Auto" again.

 Note:
Currently, the software only supports manual iris adjustment. In "Auto" mode, only the maximum iris opening is supported at this time. The above-mentioned dynamic iris function will be released in future firmware updates.

If you have additional suggestions or ideas, we welcome further discussion!
