Well, you'll read the test to understand or to try to understand.
I couldn't do better in eco mode, the deltaE close to 3 is obtained with the laser at full power but it's unusable because of the operating noise, so the calibration is in eco mode and you have the result.

Hi, Mike. Thanks for chiming in. Yeah...in my viewing experience, I found that the .47 chip was not as sharp as the .66/.67 chips. And the dynamic contrast Kraine is reporting is the worst I've seen of any of the DLP "4K" laser projectors to date. The Acer and Optoma DLPs just offer up far better dynamic numbers. I know from personal experience that the Optoma UHZ dimming was active at various APL and dynamically had very good contrast performance.

About the DE, I suppose he did have a better DE for Cinema, showing 3.2, although a tad cooler. Anyway, I know from calibrating the UHZ65 that blue is very difficult to control. And I've heard from some who complained about the difficulties in calibrating it to reference standards.

Looking back at reports of the BenQ LK990 and HT9060 and this being a rebadged BenQ, aggressive dynamic dimming shouldnt be expected..

Yes the chip at first and also the high brightness of the projector and other problem like color uniformity.

It sounds like what you are describing is an expensive projector with cheap DLP results. Expensive by comparison to other projectors with similar performance.

The Acer VL7860 and Optoma UHZ65 have no problem doing this. I will stop there the list of defects but you will see in the complete test bench that it does not stop there. As for HDR automation, it is more manual than auto.
I see..
It doesn't come as a surprise to be honest.

Yet, the mystery remains.
What exactly were they thinking, entering DLP territory with such a unit?

Instead of rebadging, it would be a lot better sticking to their guns: offering a decent LCOS experience.

It is surprising that the NZ3 would compare poorly to the LX-UH1:

It comes down to the huge market for reasonably priced, bright, "4K" DLPs and this being laser makes it even more enticing.

As far as "offering a decent Lcos experience," speaking from the NX7, I can say JVC now offers an outstanding Lcos experience.

@kraine , thank you very much for your review. I appreciate your honesty and objectivity. Also, thank you very much for translating from French to English! I have been eagerly waiting for a technical review of this unit.

I noticed you said the projector is unusable on full lamp due to operating noise. Maybe I missed it, but were you able to do any in-depth testing on full lamp mode? Or, did the 50db from the laser light source make it impossible to calibrate and test on full lamp mode?

All my measurements are made in full, eco and dynamic laser modes. It's all in the summary table. For the color temperature on the other hand, the first 3 are with laser at full power and the calibrated version is in eco mode.

The LX-NZ3 has shipped to me. Will be trying it out in a family room with nearly white walls and shooting onto a 127" diagonal 16:9 G2 FireHawk (1.3 gain).

From the review...


Operating noise:

Ouch! It’s a bad start! By activating the laser at full power, the sound level meter panics at 49dB at a distance of 50 cm. Under these conditions the NZ3 is unbearable. It is essential to select the economic mode in order to be able to consider using it over time and even then this operation only reduces the operating noise to 39dB. It’s unspeakable; we’re going to have to review this part, ladies and gentlemen, the designers of this device!


These are numbers I'd want verified. That's a REALLY big deal if it's that loud.

One of the reasons why a laser projector interested me is that I heard that they run quieter. That certainly isn’t the case with this one. I’m looking for a projector that outperforms the 6050UB (at least as bright, contrast, with lens memory) but is under 5k. Not sure it exists.

JVC has many under $5k.

Not sure where you heard that.

Laser light sources take about the same watts as a bulb per lumen. So at the same brightness they need about the same amount of cooling and thus similar fan configurations.

Any JVC RS400 or better will outperform the Epson 6050UB. That's the last 4 years of JVC projectors. Every one of JVC's new line of projectors will outperform your Epson by a large amount. We aren't allowed to talk prices here, but you should call around for pricing on b-stock NX5, NX7 and new NX5 and I suspect you'll find them in your price range given what you've said above.

One thing I've learned since purchasing my Kuro 5080 13 years ago is that contrast/blacks is far more important than sharpness/resolution.

The JVC NX series overall is a better projector than the Epson, but they are not as bright as the Epson’s 2600 lumens. The NX9 comes close at 2200 lumens, but that projector retails for $18k, so its another world price level.

I’m projecting onto a 160” screen from 23 feet so I’m looking for something with a lot of horsepower. So far I’m learning that to find something that out performs the Epson is a huge step up in price. I was hoping this LX-NZ3 would be the answer but apparently it has poor contrast and is very loud.

I would let a few more reviews come out but I would agree the very early word isn't great. Mike Garrett should be chiming in fairly soon with his impression on this board as well. A JVC projector on 160" is REALLY pushing it. I think most would tell you if you get north of 135" to be ready to look elsewhere. I have a 150" screen and the one thing I've learned over the years is unless you want to literally spend tens of thousands you're going to make a compromise of some kind with a screen that size. You either give up contrast or you give up brightness and you have to really look around to find the right blend. To me, that's where the Epson's jack of all trades master of none 5050 is a great fit for screens 140 plus. Those that run around with meters in their pockets who actually measure perfect colors and contrast etc. will tell you that their instruments are measuring a lack of perfection with Epson that they can get with the JVC and I'll respond that if you need an instrument to tell you that then it's probably not that big of a deal. I'll also admit that if I had a 135" screen or less I would go the JVC route but in my case it's VERY likely going to be the EPSON 5050 unless the LX-NZ3 has a few surprises in it.
