Novice trying to learn as much as possible before an Autocal of an RS420. I note that there are new versions 9 of the software and JVC instructions for the 2017 models. I realize that this forum is for V6/7 of the software, but as for as I can tell there is not a separate thread on calibration of the 2017 models. I am wondering if all the same DIY procedures discussed in this forum are applicable or necessary for the RS420? For example, when Javs posts...[with the RSX20s] "You can fully calibrate the hdr gamma preset and it works". Thanks in advance for any thoughts on this question.
