JVC NX9 ($18k) still too dim?

6241 Views 36 Replies 11 Participants Last post by  markmon1
Ok , this projector doesn’t quite meet $20k gear but it’s close.

I am designing a light controlled / dark home theater , with front row 10.5 feet from screen. Looking at a 150” wide 1:2.40 scope screen (2 way masking, Seymour Screen Excellence TRIM-L 150). The screen material has 0.9 unbenchmarked gain since must be acoustically transparent (Enlightor Neo).

ProjectorPro states even the JVC NX9 (2200 lumens) will only light my screen to 13 fL. If you factor in the real world gain of 0.9 that’s 11.7 fL. Too dim as 16 is ideal. And I assume ProjectorPro uses full lamp power for its calculation.

Do I really need to go the next step up to a $65k projector like Wolf TXF 5000 to get adequate brightness ?

JVC RS4500 would light that screen up. Call around you'd be surprised what street prices go for.
If you don't need good black performance on low APL scenes, you can jump into a BenQ LK series (970/990) which would light up that screen

So much fun to be in the design phase of your theater!! I did my own and loved the process. However when I finally had a real pro in to calibrate he identified some real issues with my projector and screen choice. I was left thinking I wish I had brought him in on the design phase. That chap was Kris Deering, image gurue. You could easily hire him to give you some quick tips, or a full blown consult. He is all over these forums, and is a key consultant for lumagen....

I looked at the JVC RS4500. For $35k, I am disappointed in its contrast (normal viewing one reviewer on sound and vision noted 80,000:1), as well as loud fan noise and slow HDMI switching.

Any recommendations for a 4k competitor that can light up 150” scope screen (0.9 gain) adequately in dark room ? Wolf ? Barco?
If you plan to watch a lot of HDR then a Sony 5000ES would be the way to go.

With the JVC RS4500 you would get just shy of 30fL with a .9 screen, which would be the very minimum I would consider for HDR. With the Sony 5000ES you would have close to 50fL.

The Sony could also be run at far lower power for regular SDR content and would be basically silent.

Like the JVC, the Sony can be also be purchased for way less than retail.

Blake is your screen multi masking or fixed AR frame?

If the later you could go to a 1.3 or 1.5 gain with the JVC.

Not if you’re disappointed in 80k:1 contrast. The next best contrast wise is the Sony 5000ES but that has around 20k:1 contrast and the laser dimming outside of fade to black is not well implemented. The rs4500 laser dimming is incredible. Black performance on space scenes and such are almost as good as my rs640. Far better than the rs3000. Also that review was done before jvc released its big fw update that fixed laser dimming. Lots of others can tell you this in the rs4500 owners thread.

The other projectors you listed aren’t great for contrast wolf often rebrands jvc for a huge price premium. Barco is still dlp etc.

If you are worried about HDR then a device to perform dynamic tone mapping (madVR or lumagen) lets you get good HDR with close to SDR light requirements.

I have the RS3000 on a 168" screen, and have great brightness. However, I went with the Panamorph DCR lens (for brightness and true 4k) and a Lumagen to ensure HDR tone mapping was correct (which is really all that's needed when you consider HDR and brightness).

I went through Kris Deering as well for setup (and for the purchase and calibration of some of the the gear - and worked through him on buying what he didn't sell directly). After seeing Kris's theater and looking at this all first hand, I also picked up his Legacy Audio speakers as he was looking to test some new ones.

Kris has this same setup in his theater room (except for a different screen non-AT screen). I went with the Enlightor screen after comparing them all as I wanted the extra brightness over the Neo.

I'd be surprised that if you have a light controlled room, you won't be bright enough. I have eye sight issues with darkness, and as such, can't see as well as others at night (in many cases I see nothing).

I also put up Protostar on my walls and ceiling around the screen to remove all light bouncing - which is what Kris did in his theater.

I came from a brighter (rated) PJ that wasn't actually brighter. The 3000 can really throw some light when setup right.

But call Kris Deering - tell him you spoke with Adam about his setup and your concerns, and he'll get you sorted.

Was the review by Kris? I don't recall anyone else reviewing the 4500 on SV. You might want to ask what he thinks about the 4500 now.

If you are disappointed in the contrast of the 4500 then a DLP is going to really make you sad.

Yes, the SV review was by Kris Deering in 2017. I understand a firmware update for the RS4500 markedly improved the dynamic modulation ("iris") of the laser, but I have not found any reviews for this projector since 2017.

It was released in 2016. When is JVC due to refresh this flagship model ?

They've said not this year. RS4500 is the best projector I've ever seen. Sharper than any of the sony's I have had, black performance on par with my RS500 only bested by my RS640. The dynamic dimming is implemented so well. The RS3000 was here in my room for side-by-side and it was also quite good. But JVC's dynamic iris implementation this round isn't aggressive enough for me so the RS3000's black performance just isn't where I'd want it. Still better than any competition but not in line with my RS4500 or previous generation JVC.

If you are willing to spend the money, then a Sony 5000 might be your best bet like ccool said.

There is also the Sim 2 Duo that Arrow reviewed.

@blake I went with the VW5000 for the reasons ccool96 pointed out , for a screen of that size and gain nothing short of the VW5000 or BenQ 970/990 will have sufficient light for great HDR content. I actually viewed the RS4500 and NX9 on a 150" screen 1.0 gain ST100. Even with the RS4500 on high it was really weak HDR, SDR would be ok . The NX9 was just not capable of making this accepatable at all for HDR , that was obvious immediately. The RS4500 running on high is also obnoxiously loud, even from the back of the room the unattenuated noise level was overwhelming, could be heard through all the soundtracks, it would definitely have to be mounted in some kind of hush box. Lastly, the contrast of the RS4500 running on high is the lowest level it is capable of , measures in the 8000:1 range on average from several reviews .When I considered the RS4500 it was going to be used on a 140" diagonal, maximum ,using ST130 ( 1.3 gain) and anamorphic lens would have given descent HDR , kept the laser in the mid laser position which would yield native contrast in the 20,000 range, precisely why the vast majority of owners use this screen size and run mid laser . The NX9 on a 150" screen of .9 gain is not a good combination if you want HDR to pop as it should.



29fl is suggested as minimum HDR, 50-60FL is where HDR comes to life and works best, other high end manufactures well beyond this mark already . I suggest going to see a few setups that have the equipment you are considering, for the money you intend to spend it's well worth the effort . I'm so glad I did this very thing , you get to see with your own eyes what are the results , then you can make the appropriate decision necessary especially considering your personal taste being the ultimate variable. In the end I realized what works and what does not , saved me a lot of headaches and money .



Every projector mentioned is fantastic, all throw a great image when used appropriately. What really matters is what you prefer, unless you see first hand, it's impossible to really make this decision.

What about 2020 ? Historically, how often does JVC refresh their flagship laser ?

You will know when the rest of us know.:)

Since this is their first, I would guess maybe next year. I wouldn't bet on it though, as Sony takes a couple of years between high end refreshes. JVC might do the same.

The RS4500 is JVC's first consumer " flagship " laser projector. So, there is no history to go by. I love mine, but my screen is much smaller and much higher gain ( ST130 ) than what you are planning.

See if you can make it to Cedia this year for a day or two - you might find a projector that will work for you. Nothing like seeing them in person.

SIM2 Nero4S+ I compared it to the Sony 5000 and preferred the Sim2. Its brighter and has a better picture.
I know this is going to seem like a long shot. But the BenQ LK990 4k laser DLP based projector is only $10k (vs JVC 4500 40k) and has twice the lumens (6000 vs 3000) and similar color space. HDR would look way better on this markedly less expensive projector ! I assume the down side will be contrast - how much worse will this laser DLP truly be ? I will have a fully light controlled room.

I am not comfortable spending $40k on a JVC (even $35k street) when it can’t even do HDR properly! I am sure their refresh will boost the lumens and maybe I should purchase a less expensive alternative until that comes out.

And the Sony 5000 at $85k retail is way out of budget. Edit : this is Canadian dollars. MSRP in the states is $60k USD.

I don’t know where you are getting your prices but they are extremely inflated. Actual street prices are nowhere near what you are quoting.

I am with you Craig because i paid less than retail value of an NX9 for my RS4500 - i have a 150" diagonal SI 1.3 gain screen 2,40:1 screen Chad B calibrated everything and i can't see having a much better picture quality/ the dtm in the lumagen pro made a leap in HDR picture quality as well - the Lumagen Rad Pro and Panamorph DCR Lens probably has a lot to do with the overall results with the RS4500 but even with the cost of those items added to the projector is no where near actual retail of the RS4500 - I am sure when JVC decides to upgrade their laser flagship projector it will be no problem selling the RS4500's that are already out there - and i will already have the DCR lens and Lumagen for that next jump in evolution.
