Just curious : Is your manual iris wide open or clamped down a bit?

Yeah, you got me on that one but if I am not mistaken, if you buy the 9Ghz unit and then want to upgrade it all to 18Ghz you will pay more to upgrade the cards than if you just bought the 18Ghz to begin with...right?. Upgrades are always more expensive than just buying native.

There are a couple of benefits to 9GHz inputs. They have less issues with older equipment and longer HDMI runs. It is also a significant cost cut if you don’t need all 8 inputs 18 GHz. They are also faster in switching inputs on those devices you don’t have 4K60 or HDR.

I have 2x 18GHz cards and I use only one input per each so I can still use pip/pop when they are available. I have 3x 1080p sources on the remaining 9GHz cards one of which is a Radiance 2144 that has analog legacy devices connected to it.

So does the NX9 cast a noticeably better picture than the NX7? I know it has a better lens, but does that manifest in 4K images?

I have not seen an NX 9 in person so I don't want to speak out of turn. From people who have seen both the consensus seems to be that there is a slightly sharper and Brighter Image for the nx9 but they said for the extra money it is not something that is really worth it in their opinions unless money is not a consideration. Obviously if you have the extra dough the JVC NX9 does throw a better image from all the people who have seen both.

Hello guys hope all is well.

I have a Radiance Pro with 18g cards and 9g cards. I can't get 18g working. says no input, but the 9g card works all the time i plug it in. i tried 0851 / 0850 code no luck.

I tried different hdmi cables all rated for 18g, 4.4.4. etc & 6 foot cable. no luck. i reset the Pro no luck.

What are you guys using/or did to get 18g to work? I have a strato player and sony A1E set up to hdmi 3 which will display 444 18g n enhance mode.

With the strato plugged direct to the t.v. it works , but with the Pro it doesn't. No Input. on 18g. Thanks Guys

I had the same symptom when I first installed my Radiance Pro. I resolved it by changing to a Fiber HDMI cable (RUIPRO). Nothing else changed, but my certified HDMI cable, which worked at 25 feet length without the Radiance Pro, just couldn't get it done. Not a lick of issues since I bought the fiber cable.

What is the length of the cable from your Radiance Pro to display?

Wide open for HDR.

I have the iris two clicks down for SDR. I am liking SDR closer to the 108 (-ish) nit mastering level rather the the commercial theater 48 nit (14 Foot Lamberts) level.

This sounds like something you should be talking with your dealer about. The whole point of working with a dealer is to ensure that they support the product and answer your questions! That is part of what you paid for with the product!!

Your post is confusing. You say you have plugged to 18G and 9G and HDMI 3. What SPECIFIC outputs do you have on the Radiance? Is this a model with four outputs? If so, what output are you using for 9 and for 18? What is the output configuration for those, video only or both?

Did you buy this direct from Lumagen?

Has anyone seen micro stutters - video only - when using streamers such as Apple TV4K and Roku Ultra with the latest Firmware upgrades?
I have Both on Westworld (which is 2K material) and Malaficient 4K HDR on Disney Plus using the same streamers.
I sent a e mail to Jim and he advised I should look at my HDMI cables - which are the same in a rack system from previous firmware and no chance they have moved.
No micro stutters observed when using UHD BD or Kaleidescape.
Was just wondering others experience.

I was reading the @Kris Deering review of the 4K Zappiti system. He noted the following:
Quote:
Zappiti system does not retain HDR metadata, which could cause issues with some displays.
Would this lack of HDR metadata affect the way my Lumagen does DTM? Or one of the newer JVC projector models that has DTM built in?

Last time I checked the Lumagen does pay some attention to the MaxCLL metadata presented; so if you have a test pattern with pixel data at 10000 nit for example but metadata being sent saying only 1000 nits MaxCLL you will see a different result at the top end of the luminance range (more clipped) than if the metadata was correct and stated 10000 nits.

The Lumagen uses the metadata to establish some pads so it doesn't have to guess as much. It doesn't actually need to do this, but in testing we found that it helped with titles that are in the lower nit values for most of the movie (Blade Runner for example). So there could be some minor differences in performance. Zappiti tried to fix the metadata problem but it hasn't been yet.

Thank you. Possibly good news for me. I also have some audio calibration clients who have the the current JVC PJ's that have an internal DTM capability. I would assume that those projectors would lose some or all of the DTM capability if they were to purchase a Zappiti??

JVC claims that their projector's don't rely on the metadata for their DTM solution, but I found that it did in fact change what mode was used. So at least in my testing, the metadata is used. But again, JVC claims it doesn't not.

Thanks again and congrats on your new relationship with JVC on their RS4500 + Lumagen + DeepDive AV calibration package. Does that mean you may end up going back to an R4500 from your RS3000? Just curious.

Not really a relationship per se. JVC is just promoting the combination of a 4500+Lumagen+setup/calibration from Deep Dive AV as the best video performance from their lineup. They were going to include the RS3000 in the mix as well, as it applies just as much (really to the whole lineup). I'm sticking with my RS3000 though.

unfortunately also I have noticed micro stutters never seen before the latest firmware. the cables are ruipro and for two years now they have never given problems. this only happens with streaming content

If you install the previous firmware and the micro stutters go away please post and I will do the same.
Thanks in advance.

I've not seen this, watched a fair bit of Netflix in recent days. Worth noting I run with genlock on, which shouldn't ever have Radiance-added frame skips or doubling. If you don't run with genlock on you would always potentially see them at some point but I guess it is feasible that this has got more prevalent?

Worth noting too that there is a growing amount of 4k/24.000p content on the Netflix service. AppleTV cannot play this content correctly at 24.000p and instead plays it at 23.976p. This drops 1/1000 frames (or a frame approx every 42s) which looks like microstutters.
Other players may have the same issue or the reverse issue (24.000 playback instead of 23.976p). This might appear to fit the description of a microstutter.

There is an ever-growing and non-exhaustive list of titles here:
https://www.avsforum.com/forum/39-ne...000-video.html

Might be worth reporting what the Lumagen UI is saying for the inbound and outbound refresh rates when seeing the issues.

I have mine set to Auto-Fast. Cards are all 18G, projector is JVC X7900, cable to PJ is Ruipro hybrid fibre 10m. Rack cables are all 2m monoprice 18G certified slim cables.

My AppleTV setup is different to some folk in that for AppleTV I run the ATV to the AVR (Arcam AVR550) and then video out of that to Lumagen. I only do that for the AppleTV to work around some audio issues I sometimes note on AppleTV with Atmos and audio muting / dropouts due to HDR metadata changes. It works for me, but accept it's not the most recommended of setups.

I should add I'm not recommending any of the above but it "works for me".

For micro-stutter, we have seen this sometimes be due to HDMI cabling. However, it can also be frame drops or repeats due to the mismatch being input and output rate as bobof suggests.

Video content really should be 23.98 or 59.94, and not 24.00 or 60.00. To eliminate output restarts going form 60.00 (OSD) to 59.94 (Content), our direct commands for 4k output turn "Rate Match" to Off. While 60.00 is a legal video rate, I consider it a mistake for any consumer content as it runs against defacto usage which is either 59.94 or 23.98 Hertz.

Unfortunately if sources are outputting video content a 24.00 and/or 60.00, and the drops/repeats bother you, you need to set "Rate Match" = On, to reduce the number of dropped frames.

If you have not used a direct output mode code (MENU 087X) to manually set the output you can change this in the active output style (MENU  Output  Styles  Styles0  HDMI Format  Rate Match by default). However, if you have used one of the direct output mode codes (MENU 087X), the Rate Match is forced off and you need to undo the command with MENU 0870, and a Save. Then you would set the output rate using the Menu. Please note I am talking to Patrick about either new manual output mode command that do not turn off Rate Match, or a way to again enable Rate Match after using a MENU 087X manual output mode code.

The only way to completely eliminate the frame drops and repeats completely is to turn on Genlock for the rate(s) you notice with the "micro stutter." If you still see the frame drops/repeats with Rate Match = On, then you should try Genlock on using MENU  Input  Options  Genlock  (Off, Auto24-Normal, Auto24-Fast, Auto-Normal, Auto-Fast, command. Frame drops/repeats are more noticeable at 23.98 Hertz. If you do not notice them at 59.94 Hertz, try Auto24-Normal, and if you do notice them at 59.94 Hertz try Auto-Normal.

Genlock should eliminate the frame drops/repeats, but be aware of the following:

- If a 60.00 source is active and "Rate Match" is Off, the output is 59.94. Genlock will not lock on in this case, and so it will be disabled due to this small, but significant, difference.

- Genlock increases switching time. If you have a projector with a long lock on time (most do it seems), this will be a very noticeable increase.

- I recommend having one memory with Genlock Off (e.g. MEMA), and a second with Genlock On (e.g. MEMB). Then you can switch and channel surf as before using MEMA. Then when you get to a program you want to enable Genlock for, press Pause, then switch to MEMB, wait for the picture to return, then press Play.

- For sources that are mostly used for 24 Hertz content like Bluray players, I suggest you consider using the Radiance Pro's Output Setup Menu to program a Output Style for that specific input to always outputs 24/23.98. I program our Radiance Pro this way for our Oppo 203, and our Strato, players. Since I am always starting and stopping content this means I pay the projector HDMI restart time when I first select that input.

- If you have an Oppo 203, I suggest you consder programming the OSD to always output at 24 Hertz if you are like me and use it to view movie content. This allows the movie to start without changing the rate out of the player to the Pro.

JVC and Lumagen Team Up

From AVS Insider Email
(glad to hear about collaboration)

JVC and Lumagen Team Up For Unmatched HDR Performance

In a recent press release, JVC announced it was teaming up with video processing powerhouse, Lumagen, to bring unparalleled video performance to JVC's native 4K DLA-RS4500 laser home theater projector. Chief among the upgrades offered is a reference HDR dynamic tonemapping solution which allows for frame by frame analysis and compensation. DTM elevates the already stellar performance of the RS4500 to a new level.

To get the most from this combination of hardware, both JVC and Lumagen recommend Kris Deering of Deep Dive AV for setup and calibration. While the RS4500 and Lumagen Radiance Pro video processor are intuitive enough for end-user setup, ensuring the absolute best performance requires a knowledgeable calibrator such as Kris to get the most from the hardware.

Kris Deering added that his "goal is to optimize the visual experience through advanced calibration and comprehensive system setup. The Deep Dive AV-JVC/Lumagen combination provides the best of both worlds: stunning picture quality and minimal operator intervention. Simply turn the system on, select an input, sit back and enjoy."

The press release went on to state the specific performance upgrades the Lumagen processor adds:

1. Dynamic Tone Mapping for 4K HDR material – Dynamically analyzes HDR images on a frame-by-frame basis and automatically adjusts the brightness and color to optimize HDR performance for each scene, and each frame.

2. Superior 4K Upscaling – Lumagen is renowned for the quality of their No-Ring™ scaling.

3. Advanced Calibration Capability – Allows for comprehensive 1D and 3D LUT calibration to extract the best possible performance from the JVC projector and any input source.

4. Custom sizing and aspect ratio geometry controls for optimal display of all content.

5. Auto Aspect Ratio Selection for UltraWide Screens – Properly display any aspect ratio within the UltraWide screen automatically, preserving the source’s intended aspect ratio.

6. Non-Linear Stretch – Automatically adjusts 16:9, and higher, aspect ratio sources to fill an UltraWide screen.

I feel extremely fortunate to have a JVC RS4500, a Lumagen Radiance Pro, a Panamorph DCR lens and to have had my system calibrated by Kris Deering too.
