In order for this to be true it would need to be hella' bright which solid state light sources are notoriously not in pjs, but they are improving...here's hoping 3000lm is calibrated (but afraid not...)

I'm not sure what you're talking about, but solid state light sources come in 2 flavors right now: Laser and LED. LED light sources tend not to be extra bright. But Laser light sources are some of the brightest projectors you can buy right now. This is laser.

Ahh I am sure that is correct however my question is will it have the same features and will they add features like JVC has with DTM etc. I can see getting a second projector for TV also however I learned a hard lesson buying Optoma. I will spend the extra money and go with whatever company shows they are giving the right value.

Well, just look here, to see that the menus are also from BenQ and we can assume that the automapping HDR is borrowed from W2700/W5700 :

You seem to reference TVS non-pros a lot. Do you work for the company? I find their reviews about as good as PJC. In other words not good.

Kris discussed the .67 chip in this article.
https://www.soundandvision.com/conte...s-4k-really-4k

Well, the .4"' chip displays 2k pixels in sequence, while the .66" chip uses upsampling.
In a recent comparison between the LG and Optoma UST models, the cheaper .47" appeared to produce a sharper image. Interesting.

Is this supposed to have the latest and greatest super duper tone mapping update the higher end JVC's are getting or is that left for the higher end models only?

I was thinking they probably developed it for the new projector and came up with a port to the older line of projectors.

It has auto tone mapping using the data on the disc. This is the tone mapping JVC introduce when the RS1000, 2000 and 3000 came out last year. It is not DTM.

Thanks Mike. Any chance we can get you to ask about a calibrated lumen total when you are out at CEDIA this week? Not sure if they provide those numbers or not at an expo like this.

According to folks who talked to JVC at IFA the LX-NZ3 will neither support 3D nor creative Frame Interpolation.

That's very disappointing. And weird, if it really is based on the Benq HT5550.

The LX-NZ3B/W was on display at CEDIA and as for a working prototype that is about to get its final firmware... on first inspection it looked quite good. Excellent color, brightness, and detail. Blacks looked pretty decent. Not D-ILA quality, but still quite usable and nothing glaringly "off" about it.


There is an Auto HDR Tone Mapping mode included.


We'll see what the street pricing ends up being.

The sign is a little vague. Is it just a rec709 device?

The Lx-UH1 did ~75-78% of P3, so a bit better than Rec709. If the LX-NZ3 uses a RGBRGB CW then it should do at least 80% of DCI-P3.

Are we upset about that?
I have read the visible difference between rec 709 and 100% P3 is subtle so only adding 5% more should be practically imperceptible. I have heard that HDR vs NonHDR is where the real noticeable difference is.

On a projected image using a single DMD and color wheel, I don't think you can expect too much better until you move to a three DMD chip device.

All I can say is that from what I saw of the 4k HDR footage being reproduced most average viewers would be happy. The JVC rep stated the final firmware should improve the laser unit interface even further, improving overall imaging.

zzzz bring laser to the NX line please, laser really is the next big thing, the brightness, motion and whole image just seems more stable on laser based projectors, ties in well with HDR becoming more utilised.

We just need to hold out until it's more affordable, not many consumers can afford a Z1.

I'm not sold on laser yet. It's expensive and has too short of a life for me. Plus I really don't see that much difference between laser and a really good bulb projector. Also the good really bright lasers are too noisy.

I use my projector for all media, games, sports basically a TV replacement. I put about 3000 hours a year on mine. If I had laser it would be about shot in 7 years and be nothing more than an overpriced paperweight. With a bulb, I can keep replacing it once a year and get a completely refreshed system.

Most likely I will stick with bulb projectors until microled becomes cost effective for big displays.

The stated 20K hr life is with the laser running at a constant 100% output, but since it uses dynamic dimming it will only rarely run at 100% and so laser life will be somewhat longer than 20K hrs. In fact the laser will probably not dim appreciably over the unit's entire lifetime, and it will likely fail from some cause other than the laser lamp.

If you look through the literature on solid state lamps (laser and LED) there is no support for a steady dimming over time as per a bulb projector. Projector vendors are probably stating 20K hrs because they are being overly cautious but similar laser systems have been stated to have ~60K hrs life at ~50% output:

"Installation Flexibility Meets Enduring Reliability

For installation flexibility, the BenQ LK970's BlueCore laser technology also guarantees reliable projection from any angle and a long-lasting 20,000 hours of beautiful operation that beats out lamp-based projectors. Specialized modes optimize the light source for improved energy use and prolonged projector life that's ideal for applications with 24/7 operation. Users can choose from three different light source modes to optimize energy use and extend the projector's life up to 60,000 hours in Eco Mode."

If you keep a laser projector 20,000 hours, it will certainly dim quite a bit by then, even if mostly used in low laser mode. This applies to all laser projectors, no matter if made by JVC, Sony, Epson or BenQ. I do agree with your comment, some other part of the projector will most likely break down before 20,000 hours. I think this whole talk of light source lasting 20,000 hours is really not even relevant, because 99.9% of buyers are not going to keep their projector that long. I also do not understand why people like to claim this as gospel when we don't believe the lamp life spec from these same manufacturers. To me, if the light source last 10,000 hours, that will be more than plenty for me.

I've heard all different stories on this. Some say that the laser dims progressively over the life of the projector, others state that they use some sort of capacitance system to constantly increase output to offset the dimming over the laser's life. Also the 20,000 hour is an estimate. Bulbs often state 5000-7000 hours of life but rarely do I get over 2500 of reliable light output.

There is a good possibility that when laser projector owners start hitting 10,000+ hours on their light engines that we will hear of failures and dimming. So far the laser projectors are too new and not many have more than a few 1000 hours if that.

I know they pre-test these products in controlled lab conditions but often times with new products, life estimates can be in error for real world usage.

I stated that the lamp will not likely run at full power and thus likely last far longer than 20K hrs. If the lamp lasts 60k hrs, then, at 3K hrs/year the projector would have a life of ~20 years. However, more than likely, some other component would fail before 20 years. Even lamp based DLP projectors that have dynamic lamp dimming, have lamp lives well in excess of 10K hrs.

I agree with you but it also depends on how much you use your projector. Some one like me may not want to spend $20k+ every 5 years because their laser died. At least with a bulb projector if I put 15,000 hours on the projector in 5 years, I can put a new bulb in it and at least sell the projector for something. A dead or weak laser in 5 years would be worth nothing.

I think the laser technology is great and I hope it improves. I am just saying that I don't know if it brings enough to the table yet to warrant the price increase over a similar equipped bulb projector.

But you may have a point. My last projector, A Sony, lasted 1 year and then I sold it and bought a new one this year, JVC RS3000. I think this one is going to last a lot longer given that I really like it and now it is going to be improved for free by JVC. Thanks JVC. But I guess you never know. If a brand new improved fantastic quality projector comes out late 2020, I might consider it.

If the nz3 has a p3 color filter shouldnt it be able to hit 70-80 of rec2020 with fairly high calibrated light output?

How would the light source effect motion? And for better motion, shouldnt we be rooting for dlp with better contrast since lcd/lcos pixel response can never compare to dmds?

If I had laser it would be about shot in 7 years and be nothing more than an overpriced paperweight. With a bulb, I can keep replacing it once a year and get a completely refreshed system.
I do the same, the projectors on 12 hours a day 7 days a week. On my w1070, I would get 7-8000 hours before the bulb was too dim. I use the dynamic and low lamp modes, and use the blank/hide function often throughout the day. A big cause of decreasing bulb life is the striking of the lamp. The laser has no loss of life from turning on and off, and using the dynanic dimming and that blank feature to turn the laser off but keep the unit on should hopefully provide a very long life.

Its actually for this reason that im leaning more towards laser for the next purchase. As using a lamp projector like that with more expensive jvc lamps can really ramp up your costs.

There is a good possibility that when laser projector owners start hitting 10,000+ hours on their light engines that we will hear of failures and dimming. So far the laser projectors are too new and not many have more than a few 1000 hours if that.

I know they pre-test these products in controlled lab conditions but often times with new products, life estimates can be in error for real world usage.
Only way the projector can do this, is if you run the projector at less than half capacity the whole time. Also the projector would have to be designed to be able to do this.

The JVC RS4500 comes from an industrial / commercial / simulation model that no doubt has seen many thousands of hours of actual use.

Most likely I will stick with bulb projectors until microled becomes cost effective for big displays.
If you are good with a bulb projector like in the NX series, that means you'd be also good with laser being on mid laser. That increases your laser life to 30000 hours instead of 20000 hours. If you use your NX projector on LOW then you'd also be able to use the RS4500 on low which increases the life to 40000 hours. Then, if you watch scifi or content that is dark, the laser dimming kicks in to increase the black performance but this also increases the laser life as its driving the lasers far less.

One guy had about 7500 hours on his running all on high lamp and measured lumens didn't drop *at all*.

At 3000 hours per year, your NX series projector will have a broken dynamic iris far before the laser unit dies out. Most likely you could get to about 7 years on an RS4500 with your current usage then go a couple more years with it on high laser. I also watch tv, play games on my projector and put about 2500 hours a year on my unit. I ran a spreadsheet and using even dimming to half life it puts me at about 9 years before I have to start using high laser. But since some actual users did measurements and reported no laser change at as much as 7500 hours, I think the drop off will be better and not gradual to the end.

You could be right and I am sure that you love your RS4500. It is an excellent projector. However, I am very happy with my RS3000 for now. Who knows what I will be thinking in 5 years? I'm sure Mike would like for me to purchase a new projector every year. Maybe my next one will be a laser. There is something appealing about having a toy with "Frik'n Laser Beams".
