Hmmmm, perhaps some others can chime in...I know it sounds stooopid, but just double check u r using the 3D blu Ray not the regular blu Ray
Lol your good, stuffs hard to explain. And I have made that mistake, but it’s the 3D disc.

It DOES go into 3D, glasses work.. it just stays in natural mode so I have to manually switch.. I’d switch to a 3D Picture mode but there isn’t one.

Trying to make one.. So far high lamp wide open, gamma 2.4 and Xenon 2 color temp seem the best, but I’m positive it can look better.

The more things change, the more they stay the same.

Yes, u should create a 3D picture mode...I use gamma 2.4, high lamp, iris wide open, natural mode, color temp 6500...looks awesome!

Edit: u will need to manually switch to the new 3D picture mode if you switched picture mode between 3D viewings...

I'd like to believe that, but I am afraid it's wishful thinking. Maybe I'll measure mine again when I crack 2000 hours.

Frank, I only have the Vertex 1, but I've set it up to do a long-term test of the DV hack. So far so good.

Yes and no...my one issue with Frame Adapt (which works great most of the time) is when the metadata on the disc is incorrect...you'll be fussing with settings between Auto, Low, Middle, and High. With the DV hack thus far, when a DV disc is detected, it looks like Frame Adapt without any of the hassle.

It's not just JVC LLDV. Any HDR10 display can be fed LLDV - low latency Dolby Vision. The display just needs to be in an HDR picture mode whether selected manually, by having the HDfury device include HDR10 metadata, or by using the HDfury device JVC RS-232 command macros.

The AVS thread is here where you can find instructions on configuring the HDfury device, including downloads of custom LLDV EDIDs:

https://www.avsforum.com/forum/465-h...rojectors.html

There is a similar thread on the "European" AV forum.

Some want to call this Dynamic Tone Mapping. It is Dolby Vision and if you want to call DV DTM that is up to you. I prefer to not do so.

LLDV was introduced by Dolby and Sony. Sony TVs cannot process a full Dolby Vision signal. With LLDV it is the player that performs tone mapping using the Dolby Vision content scene by scene metadata layer and not the display. There is also a Dolby Vision data block in the EDID that a display presents to the player that includes whether the display prefers DCI-P3 or BT2020, its RGB X/Y values, its maximum and minimum luminance nit values, and other information regarding the display's capabilities that the player uses to tone map.

LLDV is output from the player as a 4K 4:2:2 12-bit signal that closely follows ST 2084. While we don't know everything about how Sony TVs process this signal, we can apply an HDR curve in our TV or projectors to the input and get good results.

With an HDfury device you can configure it to present an EDID to the player that reports support for LLDV but not full Dolby Vision. This will trigger any player that has support for LLDV to output LLDV when playing a Dolby Vision title.

The newer HDfury devices, Vertex 2, Diva, and Maestro include more LLDV related capabilities than the earlier ones.

- All models include the built-in custom Sony A1 LLDV EDID. You would need either a DCI-P3 color profile applied in the JVC or load a custom color profile that matches the values in the EDID. Dominc Chan created such a custom profile.

- As I mentiond earlier markswift2003 created a custom BT2020 LLDV EDID from the 4K HDR10 full audio EDID in the HDfury device and added an LLDV data block. You can load this EDID to any of the HDfury models.

- The newer models include the ability to configure your own custom DV data block using the browser based web server interface that gives advanced users the ability to fine tune the LLDV related EDID values presented to a player.

- The newer models also have the ability to include custom HDR10 metadata only when the signal is LLDV. With older models custom metadata is either on or off that is sent with all input including SDR and HDR10 that you don't want. Like I mentioned the only reason to send HDR10 metadata is to trigger the display into an HDR picture mode. I don't send any metadata as I use the JVC RS-232 macros for user mode switching based on content type. The newer models have an LLDV macro. The older models do not.

Some players also have the ability to convert SDR and HDR10 content to Dolby Vision that can then be ouput as LLDV. These include the Oppo 203, newer Sony UHD players, and the Apple TV 4K. Players like the UB820/UB9000 can output LLDV for Dolby Vision content but cannot convert SDR and HDR10.

I use MadVR to tone map all of my UHD and HD discs so I do not output LLDV for these. The rest of my UHD viewing is from my Apple TV 4K. With so much DV content available on the ATV4K, it is a good choice for LLDV. I was never satisfied with HDR10 from my ATV4K. The Vincent Teoh video I posted details some of the shortcomings of HDR10 from the ATV4K. With LLDV output instead, the ATV4K is now my go to streaming player.

Should you send LLDV instead of using the JVC Frame Adapt DTM? Probably not in my opinion, but that is your choice to make. Frame Adapt can examine each frame. LLDV is dependent upon the scene by scene DV metadata, but does allow for display device capabilities to be considered in tone mapping.

One final note. I think it was either Kris Deering or Stacy Spears that reported that there are issues with Dolby's LLDV implementation.

I believe it was markswift2003 rather than markmon1 who created the BT2020 LLDV EDID.

Correct. There is no auto switch to a 3D mode. If you want custom, will have to make your own and select it when playing 3D disc.

Who exactly measured it and with what instrument ? Also, for every person on here that swears their lamp hasn't dimmed one iota after 3000 hours, I've got a lamp that isn't bright enough after 1000 hours of my own. So I will believe it when I measure that on my own projector after 6000 hours. Besides, there can be a lot of variables when it comes to something like a projector.

Hope for the best but plan for the worst is my motto.

1. What HDR curve do you apply on your projector and how is this setup ?

2. If you use the LLDV trick and the Sony A1 LLDV EDID, do you not have to change that edid to match all the parameters of your projectors ? Does HD fury have custom profiles for the current JVC 4K projectors (that you would use instead of Sony A1)?

Okay - I'm hopeful I'll get the same. I don't take anything in home theater for granted, but I wouldn't mind having a far longer life for my RS4500 !

Since I have an older JVC RS500, I use a 1000 nit custom Arve curve. And have the Max Lum value in the Dolby Vision block of the EDID set to 1000.

The Sony A1 LLDV EDID has RGB values that are very close to DCI-P3. And Dominic Chan created a custom color profile for JVC projectors that that matches the A1 LLDV EDID.

If you have a newer HDfury box you can set the EDID values to whatever values you want. DV Data Block page of the newer HDfury devices attached. The default values are those of the Sony A1 EDID:

Why 1000 nits max when projector can’t go near that ? Is this another value where you have to factor in projector “scale factor” (although these are usually 4-6x the PJ max nits)

Hey, what about my custom gamma profile?
Of course, setting gamma to 2.4 is a quicker approach to compensate the overall reduction to 2 that I reported to you. However my custom profile was thought to compensate the gamma deviation more precisely. Have you tried it then?

If I remember right there was a user at 7500 hours 100% high laser and another around 6000 hours high laser and both reported zero light loss.
You're running mid and low laser with dynamic dimming on top of that. You'll get a lot more life.

Thanks, sorry have not been in my theatre for a week now as we are starting my summer hobby now (Car season) and my Porsche has a short circuit which is draining my battery so I’m deep into diagnostic mode and it’s driving me crazy...another anal hobby!

I suspect I’ll load your custom 3D gamma next time I run Autocal again...can you please refresh my memory on how to import a custom gamma curve? I eventually will give it a try but have not been in movie mode of late...thanks again

But feel free to experiment with the Max Luminence settings in the DV tab.

The point is, the settings in the DV tab and the projector settings should match.

By the way, my JVC X7900 has a decent factory installed ST.2084 PQ curve, which is made for MaxCLL of 1000 Nits.

I suspect I’ll load your custom 3D gamma next time I run Autocal again...can you please refresh my memory on how to import a custom gamma curve? I eventually will give it a try but have not been in movie mode of late...thanks again
So home cinema is not the more expensive hobby you have
You have to load it by using JVC software. Click on 4th icon "Import/Export" and select "Gamma Data".
After having imported it, make sure to select the right custom curve and the "import" option within the VPR menu.

Thanks, trust me I’m on the Porsche boards also asking stoooopid questions..,

When I import your custom gamma, do I need to have my projector in my custom 3D picture mode and the gamma set to custom also and then do the import? I’m trying to remember as I use to import Arve curves all the time...Thanks, sorry for the questions and if u know how to debug a short circuit, please let me know

I usually do like you described. However make sure to select the right gamma slot in the software. That's important.
Have you created a custom 3D picture mode?

Arve’s Tool loads the curve into the picture mode and gamma currently selected on the projector, so the projector must be set up accordingly including the Correction Value (must be in Import) when you load the curve.

Autocal behaves differently. You have tell the software which gamma slot you want the curve to load into, regardless of the current selection in the projector.

Ahhhhh, so there is no need to set the projector up accordingly before the import? Simply tell Autocal which gamma slot and then after the import chose my 3D picture mode and the new gamma based on the import?

if you set the VPR first, you will see the results immediately
