Anybody that is wanting the free spare lamp, had better be ordering before end of this month.
To get the free lamp you have order by 3/31/19 and mail in the original projector UPC barcode from the box no later than 4/30/19. With them still working on filling pre-orders would you expect projectors ordered in the next 2 weeks to be delivered before 4/29?
I posed these questions on the other forum, but thought I'd do here as well, to pick the brains available here. I'm trying to grasp what these new Panasonic-specific "Color Profiles" bring to the table, as well as exactly what they are, and what they do.Previous to the new JVC Firmware update, bringing the Panasonic specific color profiles, if you were using the UB820/UB9000, you had 2 main choices (actually more, if you include turning the HDR Optimizer On or Off, but they're not important relative to the questions I'm asking):1. Output HDR from the Panasonic, set the JVC Color Profile to HDR, (or BT2020 if you want to use the filter), and Gamma to HDR(PQ).The Tone-Mapping takes place in the JVC's Gamma adjustments in the HDR(PQ) curve, with a slider to tweak to a given screen/room/preference (and also the Panasonic when choosing the appropriate Display type for 350 or 500 nits, but let's also ignore that for the purposes of understanding the basics here).2. Output SDR-BT2020 from the Panasonic, set the JVC Color Profile to HDR, (or BT2020 if you want to use the filter), and Gamma to 2.2.The Tone-Mapping takes place in the Panasonic, and is based on seeing a plain Gamma of 2.2 in the Projector. The Projector supplies a Color Profile, but there is nothing "HDR-like" in its Gamma, since it's plain old 2.2Now, we have new Panasonic-specific Color Profiles in the JVC's, but the Gamma is still being set to 2.2. As Mike pointed out in the other thread, the Panasonic will be doing the Tone-Mapping, and the JVC is still using it's 'regular' Gamma of 2.2, so not doing anything "HDR-like" at all.The question then is how is this new approach different from Option 2 above, where the Panasonic is outputting SDR-BT2020? Doesn't it have to be doing this, since the JVC is still set to Gamma 2.2, as it has to be in that situation??It has been my understanding that the Color Profile in the JVC is addressing color gamut and color space type issues (with WCG being one dimension of UHD content), while Gamma addresses the HDR component of UHD content. If that is the case, then it seems that the new Color Profiles only operate to impact color gamut and color space, and *not* the HDR component (which is a Gamma function).Further, how are these new Color Profiles different from the current HDR (no filter) and BT2020 (filter in use)??There may not be sufficient data or knowledge of these functions to provide an answer yet, but I would really like to understand how Tone-mapping is being handled in this new set-up, if the JVC is set to 2.2, whether or not the Panasonic outputting HDR or SDR, and if/how this is different from the SDR-2020 currently available with these Panasonic players.Thanks!
See attached for instructions.
The HDR gamma data is reflected inside the above Projector Color Profiles. As a result, the HDR Gamma mode is not used.
Is anybody familiar with just what's going on here? How are gamma adjustments made inside a Color Profile?
You can specify a gamma curve (1.8 to 2.6, default 2.2) when you create a colour profile, along with the gamut primaries and white point coordinates. See attached.Only a power gamma curve though, PQ is not selectable, at least not in the JVC Autocal software.
Have you checked to see if this limitation on Gamma selection is still present in the new version of Autocal they just released?
I'd like to give a quick thanks to those of you that helped me find this new forum. Hopefully better than the AVS BS that we've had to put up with. Although this confirmation with the letters and question is getting old.
