That's kinda "screwy," wouldn't you say? I wonder if it was germane to yours or whether they're all like that. Either way, I'll watch out for it.

(But here's the $64,000 question: "Why were you inspecting the lamp compartment?" [Oh..no, I'm not taking my eye off the ball.]) Nice anecdote and thanks for the post!

I guess I could build the system I have in mind and then you would see what I am talking about, just another way of moving the lens when you don't want to use it. Nothing would roll without you wanting it to of course, if built right. I myself have been custom woodworking for 37 years, started when I was 10, ya I guess I was the woodworking dork

How does the LLDV mod work and what would I need to be able to use it myself? PM me if easier.

Those look great!!! And keep in mind the upscaler in your UB9000 is doing a great job too. I couldn't believe how clean the images from my Panasonic player looked.

It's a tone mapping modification advocated by Dave Harper and relies on a player and a coding device like the Vertex. Bytehoven gave it the ol' college try and reported it improved the image. I haven't tested it yet, so I'm not sure whether it's technologically dynamically active, but they would be the ones "in the know."

Hi Archi...

In a nut shell... Dobly has a Dolby Vision (DV) solution for displays which by design lack the processing power to deliver the DV experience. Both Sony and LG have such displays. The particular display, maybe the 1st, was/is the Sony A1 OLED.

The solution was to have the source device provide the DV processing and output an HDR10 signal which has been tone mapped. This process is known as LLDV Player Led DV processing.

TheLLDV capable source devices known so far are:

OPPO 203 and 205 players (not sure about the variants)
Sony x700, x800m2 and x1100es players
Apple TV 4k 32 & 64 streaming boxes

These devices, when connected to the Sony A1 OLED, would enable the Dolby LLDV (player Led) DV processing.

Enter the HDFURY.

As in previous EDID challenged situations, a HDFury Vertex, Vertex2, Diva and Maestro, have the capability to spoof these sources devices to think they are connected to the Sony A1 or other LG displays, depending on which HDfury device you have. The older Vertex has the more limited LLDV support, but it works well enough to support the Sony A1 LLDV EDID on it's two input/output connections. Which I will use with the Sony x800m2 and ATV4K 64.

Now, the consensus at 1st was, the LLDV process might only work with DV mastered content. But it turns out, the DV tone mapping process, also works with HDR10 mastered content. So in both cases, it appears the LLDV process is working frame by frame, establishing a histogram, to process the source and provide an HDR PQ10 (EOTF) compliant output signal, which would work with any HDR10 compliant display OR projector.

In my case with the x990... my setup is the x800m2 -> Vertex -> x990. I set up the x990 with my best st2084 tone map, which is either my ChadB normal or bright custom curve, making it ready to receive the HDR PQ10 signal. With Chad curves active, I then use a DM HDR10 White Clipping pattern to increase Master Contrast on the x990, so that the projector just resolves the 712 bar, just below 1000 nits. This allows me to increase my master contrast from a normal +2 to +12, which significantly increases peak white lumens, while retaining white highlights of the DV and HDR10 content I have tested so far.

The caveat... my ability to increase peak white lumens, is limited to the point where I will actually begin to crush white highlights. I figure my setup with LLDV at +12 master contrast, is similar to the UB820 with the Dynamic Luminance slider at +6, which honestly is enough. I'd also note, while leaving master contrast set at +12 is working with most titles, this process still benefits from some hands on tweaking for some titles, but the tweaking is available and does work, and is not very different compared to adjusting the dynamic luminance slider on the ub820.

I'd note, for any content where the MaxCLL is below 1000 nits, the master contrast can be pushed even further, still preserving white highlights while further increasing peak white lumens.

I'd also note, the x800m2 in DV/LLDV mode, is remapping source content to a 1000nit MaxCCL, not unlike what the ub820 optimizer is doing, while preserving higher nit highlights. This remap is right in the ball park of the x990 st2084 controls and custom curve range.

Bottom line... the image quality using the LLDV hack, is superior to the best I can get with the ub820. The thread linked in my sig, or posted by sky, givens some observation examples.

I may upgrade to the Vertex2 or Diva, just to have access to some of the LLDV macro features missing on the Vertex.

10 years ago I have back room with a hole professionally done which projects into my home theatre room.

The shelf is 600mm side by 700mm depth.
 
Should it be okay ? Looking at specs projector is 500mm wide.
 
Should that be fine ? Or should I place projector back into room ?
 
The specs say projector needs 300mm space on the side to the wall.

I would use your port hole and place a non reflective high grade glass there at a slight angle.

I have a room for that purpose and it is quite small but is open to a storage area through my AV rack so it is naturally circulated. My set up is similar to yours with a shelf that is close to the ceiling and another wall on one side.



Here is a close up of where the projector sits. It is shocking how much heat is thrown out the front of the unit and I would not put it any closer than 4-6 inches unless you are very careful. I use a little PC fan with a 12 volt trigger and it moves the hot air out from the front of the unit quite well. On the left side of the unit I have around 8 inches to the wall and I do not feel it getting hot there in any way.



With my first JVC projector the front of the unit was only 2-3 inches from the port hole and I started to notice this strange hazy shadow being swirled onto the screen. I thought it was malfunctioning but after reading I realized I was seeing the heat phase phenomena that is warned about in the JVC user manual. That led me to my current solution and it has not been an issue since. But that projector will heat up that little room quick so be careful.

Why Remove DCR lens

I am just wondering why you need to remove the lens for 16:9 content. I thought Anamorphic D setting was supposed to solve the 16:9 format with the JVC NX series. I understand that for 3D movies it may be necessary but why for just plain 16:9 content?

Craig has the RS4500. The RS4500 hasn't received Dynamic Tone Mapping firmware update which also included the support for the Anamorphic D lens setting.

Because in my case it's easy to do, and then I don't need to re-scale the picture to watch 16:9 through the lens. I can watch it as native 3840 x 2160.

But I do have the Lumagen Radiance Pro, so I could re-scale 16:9 with the lens in place.

Agreed, no reason to throw out resolution and detail if you don't have to.

Now that the Frame Adapt HDR feature in firmware 3.10 has been out for about a month, has anyone found any good reviews on it? Sadly, I haven't been able to find any reviews.

And I usually watch nothing but scope movies for days or 16:9 content for days anyway. But since the lens is literally at eye level, it's easy enough to remove. I don't care so much for the convenience of leaving it in place as having the best picture possible. I tend to like playing the role of projectionist running a ( tiny ) theater anyway. Also, I like to play being a sommalier - sometimes in the theater too !

Plenty of real world feedback in this thread and this one: https://www.avsforum.com/forum/24-di...rojectors.html

Synopsis is that it's excellent and for many it's providing the best 4K picture we've seen.

The DCR is a compression lens. If you move it, the image will no longer fit your screen. You would have to reduce the image size. So you would need to use lens memory also.

I still cringe when I see fixed lens set-ups and I think about how we have gotten to the point where we have these gorgeous 4k projectors and people are happy with throwing away 20% of their 4k resolution when watching 16:9 content.

Also, I like to play being a sommalier - sometimes in the theater too !
So what do you like to serve your quests? I understand now. I thought there was some issue with the DCR lens as i will be setting up a RS2000 with DCR lens once my theater is done (hopefully before Thanksgiving).

I've been keeping up with the other thread. In your initial observations there were some titles that the Panasonic handled better and some LLDV did. Was it just experimentation that led to you determining LLDV was better in all cases? For other projectors or JVC projectors without a custom gamma curve would this solution be as effective? Are you finding that most titles need no tweaking once the base settings are determined? Is it working well with titles without metadata and DV (sorry if this was answered and I missed it)?

I'm mostly curious about how much benefit this has for projectors that don't have custom gamma curves available and how much tweaking is involved. Seems like something that could have big benefits in those cases.

Synopsis is that it's excellent and for many it's providing the best 4K picture we've seen.
Thanks. Yes, I've been reading good user reviews in that one. Hopefully, we'll start seeing some official reviews from the respected calibrators in the AV community. Thanks again.

I think the fact that this is something added to an existing product has kept it off the professional radar. They seem more concerned with reviewing new products. Though Kris Deering has weighed in on it with some very positive comments. So it's not been entirely overlooked. Might be a few others I'm not recalling too.

Yes, I was thinking the same thing. It's a shame too, cause the Frame Adapt HDR feature is a big deal and a game changer, in my opinion, at least.

Indeed. I think it would be nice for the pro's to go back to their reviews and update them for the new Sony and JVC firmware.

Depends. If I feel like splurging, Brunello or Barolo. But my guests bring plenty of local Zinfandels to drink.
