I would agree my indoor scenes look really dark now, was bothering me watching the Queen's Gambit.

 

Guess we'll hold tight to see what JVC says.

 

Also I've noticed the iris click creep back in :/

 

 

If the Iris is still audibly making a "clicking" sound i am afraid you will need to send it in for a fix!!!   Eventually it will completely fail and if at that time if your out of warranty it would be a VERY costly fix!  ☹️

 

RE...New 3:50 Firmware......much talk off the forums.....quite a few issues with it!!! ☹️

well good timing as a new N7 arrived in time for moving on my x7000     UNPACKING Firstly I have to say JVC have VERY much beefed up the packaging on this new JVC series the polystyrene

Got it up but holy smoke it was heavy....... Currently running 1.18 firmware and needed 1 click red and blue to align. Colors are so bright and the blacks look so good. N7 must be bloody amazing. Pl

Another happy N7 owner here. Got mine about 6 weeks ago upgrading from a HD350. Absolutely blown away with the out of box performance. Bought mine aware of potential issues but have been a happy

I know you're right, unfortunately :(

 

Mmm, a bit concerning. I had a look at when you have the iris to manual, I can't move it above 0 so not sure how I'm supposed to set it at 1?

 

I could go back to using HDR10 profile, it has all my calibration settings in it already.

The Iris range is 0 to -15    you CAN NOT  move it "Above"  "0"

That’s what I figured. 


Do you think they mean -1?

I "think" they are referring to using a "Manual" setting of +1  in the JVC DTM interface INSTEAD of using the TO ( Theatre Optimiser)  NOT the Iris...😊

Make sure you turn off Theatre Optimiser :) 

 

Lol, I was fumbling around trying to work out where the heck to make the change. That did it, and found it after that, thanks. I'll let you guys know how it goes.

Hi all,

 

Here's the D.I. noise if you'd like to hear it:

 

https://www.dropbox.com/s/jc27hgvolqswyuo/DI Click.mp3?dl=0

 

I've been in touch with my retailer and he's referred me a few JVC service centers not too far from me, apparently all they need is the invoice to prove it's within warranty period. I will get in touch with them and see what the process is. I'm guessing they won't be able to give me an ETA on how long they'll have it for, sigh.

 

I had a 30 min period today where it was quiet and 'normal' but unfortunately didn't last long.

 

In other news setting the tone mapping to 1 has improved the brightness of indoor scenes considerably. So theatre optimiser is off until they address that.

Yes I heard that clicking. Not good at all.



From Kris regarding TO:

Some thoughts on TO vs non-TO. First, they are the same thing in terms of tone mapping. JVC isn't using different tone mapping algorithms for one vs the other. TO is designed to give the tone mapping more information to work with so that it can (hopefully) make better decisions when it comes to how to implement the tone map (basically trying to get a good idea of how much light it has to work with) instead of making a general assumption to work across all usage cases.

 

For example. If you have say 100 nits, and the non-TO tone mapping is based on the assumption that the end user has about 100 nits you get a tone map that is pretty much ideal to what JVC intended. If you use the TO and JVC's processing estimates that you have about 100 nits based on the parameters, you get the same tone map. Obviously there will be differences based on where you set the levels, but these should be fairly small.

 

Now if you are not using TO and you are way off what JVC's default estimate is, the results could be drastically different than using TO because TO may do a far better job of estimating your actual light. Based on comments here, most people tend to be in a rather small range of light off screen, so I would expect the differences to be smaller rather than larger.

 

I also find that most people seem to prefer a more compressed dynamic range than a higher one (they want an overall brighter picture, not a more dynamic one). I think this is the case with flat panels too. This goes back to my comments about people not understanding that HDR was never intended to be a bright format, but a dynamic one. I think the majority of people don't understand the difference between BRIGHT and DYNAMIC any more than they didn't understand it with audio when you talk about LOUD vs DYNAMIC. When they were given high dynamic range music they didn't like it and found it unusable in most normal listening environments. They are seeing the same thing with HDR and we are already seeing steps being taken to compress the image because once again, people don't like it in normal viewing environments.

I currently have an x7500 and have been pondering an upgrade to nx5 as the prices seem to have dropped a bit from retail. I have a panasonic ub420 that I use for bluray/UHD. I also have a dedicated theatre room with blockout blind and dark walls/ceiling. The pj is shelf mounted at rear of room and projects onto 120 inch motorized screen over a distance of approx 4m lens to screen, seating position is around 3m.

 

Would I see a significant difference in the proposed upgrade, especially given the new firmware, or should I wait for either further price drops or new pj release?

This one on sale for pre order venno ? JVC DLA-N5 4K High Resolution Projector Black | Klapp Audio Visual (klappav.com.au)

 

Dont expect any new jvc's for ages thanks to covid etc . If you play a lot of uhd blurays the new tone mapping  and TO will help heaps compared compared to the fixed curve tone mapping you have . I would keep an eye out on any posts concerning iris mechanisms and potential firmwares associated 😉

I managed to pick up one of the last N7s. It arrived here a couple day’s ago and am yet to turn it on. 
 

Very excited to see how she looks, although hoping it has no issues that have been bothering some people. 
 

I also have a slide and an Aussiemorphic Mk4 lens ready to go. 
 

I will read back through the myriad pages in this post and see what potential issues to look out for. Wish me luck!

Don't over analyse or you will go nuts.

 Just enjoy the visual goodness.

OK got my N7 mounted and powered up! I have not placed the slide or anamorphic lens in front yet. Will do that tonight. Just wanted to get the vanilla PJ all set up nicely first.

 

OK, so mine doesn't have the latest 3.51 firmware. So I'll download that tonight and install.

 

Quick question - how do I map 'anamorphic mode' to a button on the remote?

 

My old X9500 had a button on the remote, but this new model doesn't, and it's a hell of a pain having to go into the menu to switch to anamorphic to get the slide to trigger and move the lens in place. I'm sure this has been asked before but there's a lot of posts in here!!

Oh - another question, or observation...

 

The N7 is quite noisy in high lamp mode. Makes my otherwise dead silent Theatre room sound like there's .... well... a noisy projector in the room.

 

It's currently mounted on a shelf that's attached to the ceiling which is open at the front and back.

 

Would it be problematic if I were to 'box it in' by covering up the front and back of the shelf and then cutting a larger opening for it to ventilate into the roof cavity? It's a big roof cavity up there so plenty of space for the heat to dissipate into. Or is this considered bad practice?

 

Sadly I can't mount it any further back as that backs out to outside. And switching to low lamp mode is a no go for me, as I don't feel it's bright enough for my viewing preferences if I do that. Running a 165" scope screen.

I don’t use high lamp mode - as you say, too noisy. 
 

The fan kicks in fairly often on mine, the projector gets quite hot & heats the room. Mine’s mounted with nothing surrounding it so I can only imagine if something was.

Ugh, yeah I have run high lamp mode with my previous three JVC projectors, and they have all had a little noise but not too bad. This one is noticeable enough to be annoying though. Movies and shows with constant noise probably would mask it, but any quiet scenes you would definitely notice it. Anyway, I'll add it to the list of things to do when I renovate the room.

Yeah - I find mine bright enough on low lamp (especially now that I actually have the iris set properly again). But I didn't have a previous projector for comparison.

Same here, I run mine on low lamp for a 130” scope screen because high lamp was too noisy and noticeable in quiet scenes.

 

Some people on the avs forum have built a hush box around the projector which keeps the noise down, you just have to ensue it’s well ventilated.

The roof cavity is likely 70+ degrees on a very hot day. As others have mentioned, a hush box with excellent ventilation is a better option. Make sure you use optical glass, not ordinary glass.

Hey Scottie,

 

I have the N7 with the Aussiemorphic mk4 and the slide too. The button you are looking for is "Setting Memory".

 

You can store up to 10 profiles for different levels of zoom, anamorphic modes etc. I have about 4 or 5 set up up for different aspect ratios, sliding the lens in and out, etc, maintaining the image height.

 

I'm same as you, I'm finding the N7 very noisy on high lamp. Don't generally notice but actually was a bit annoying watching "A Quiet Place" last weekend in the quiet sections.

 

I'll be interest to see what you find out investigating the hush box.

 

Cheers

A Quiet Place is the worst movie for hearing the high lamp thats for sure :)

Ah legend! OK so I'll have a play with that button and see how I end up. Thanks mate. Hoping to have a better play with it tonight. I have done the 3.51 firmware update earlier today and everything seems OK. 

 

What do you think of the Aussiemorphic MK4?

 FWIW I am going to try these guys...

 

Amazon AU free shipping, $122AUD Shipped. Says Original, Spec and pics are correct NSHA265JK bulbs... Looks like they come from China, but I am sure they are made there anyway. I might confirm they are actually USHIO first.

 

https://www.amazon.com.au/gp/product/B08CZV3B2L/ref=ox_sc_act_title_1?smid=A2H2E7OAWC994G&psc=1

 

Else, you can try these guys in Europe, 115 Euro and only 6 euro shipping. Ushio brand though its the NSHA250JK. Will work out less than the US deal Dominic was doing.

 

https://www.beamer-parts.eu/projector-lamp/ushio/ushio-nsha250jk/

 

It always pissed me off that the JVC lamps and specs list 265w bulbs, and EVEN the housing states 265w bulbs, but the bulb itself in the 3 housings I have here are 250w.

 

There IS an Ushio 265W bulb, so I am going to do my best to actually get one of those.

 

 

Hi Javs,

 

Did you end up trying these bulbs? My N7 is getting dim and thinking of getting a replacement soon.

Well, I waved a sad and sorry goodbye to my NX-7 today to try and get the D.I. issue sorted. 

IMG_5779.thumb.JPG.d23c263155c22dc84116310913342bf0.JPG

 

 

Bye bye love, goodbye happiness, hello emptiness .... ;)

 

It actually almost was cry-worthy, since I don't know when I'll get it back (backlog due to Covid, Christmas/NY etc etc).

 

I also got a flat tyre just as I got there as well, just to top it all off!

 

Anyway ... first world problems I suppose.

Decided to go with beamer parts. 

Will take measurements on the brightness and how it drops off over time. 

I also just ordered a lamp (just the bulb) for the N7 from Beamer. Should be here in a few days by DHL. I found them great to deal with.

Received my bulb on Sunday! Took about 6 days to arrive which is pretty impressive. 

 

Unfortunately, the bulb's performance is really underwhelming.

After calibration, it was only able to produce 18ftl at 0 Iris. This is on a 100" screen at 3.5m distance. 

Pretty sure the JVC bulb it was replacing was brighter even at 1200 hours. 

 

The build quality is also poor.

The seal around the bulb is sloppy, and there are water spots all around it. 

 

Let's see how Beamer responds.

Not too surprising I wouldn't have thought? That's why I just bought another original bulb in housing. But disappointing for you, for sure!

Well, people have been pretty happy with Dominic's bulbs and I think these Ushio bulbs are supposed to perform about 80% of the original bulb.

My bulb is below that sadly. Will see how this performs after a few hundred hours. 

 

I'll keep testing bulbs from other suppliers, and eventually get a legit JVC bulb if these aftermarket bulbs keep disappointing me.

So I am wondering people's thoughts on this. The projector has been with the repairer for nearly 1 week in regards to the noisy D.I., and I called them today. Apparently, they can't find anything wrong with it, they can't hear the iris and reckon it's one of the quietest they have heard. I am not sure if it's not doing what it's been doing at home (and has been fixed) or it is doing it, and what I've been hearing is normal.

 

They've said I am welcome to come and pick it up (super tempting as I am missing it) but at the same time I am worried that when I get it home, it's going to have the same issue. I could swear it wasn't making this noise when I first got it. What I am hoping they will allow is for me to go there and take a listen and rule out whether it's just not doing it, or whether it is, and that's just the way it's going to be.
