I had a chance to spend an hour with both the Jvc N7 and the Sony 695ES (570ES here in Europe).

We were in a light controlled room and the projectors were placed at 7 mt. (23 feet) from the screen.

The screen was an Elite screen Dark Star 9 - 0,8 gain 123” in 16:9 format.

We had to switch from one to the other, it was not possible to run them together at the same time to split the screen.

I personally own a Sony 695ES and I was considering switching to the N7. I previously owned both JVC and Sony projectors.

I had my i1 Display pro that I brought to measure the light on screen but there was not time to calibrate the projectors.

So I set the Sony to Reference profile, D65 color balance, Gamma 2.2, dynamic iris on to full.

The Jvc to Natural profile, 6500K color balance, Gamma 2.2, auto iris 2, manual iris full open.

Regarding the light on screen I measured the Sony to have 37 Nits in low lamp mode and 63 Nits in high lamp mode. The Jvc was at 50 Nits in low lamp and 62 in High lamp. So at high lamp both projectors have the same light output.

We compared the two projectors with Sony in high lamp and Jvc in low lamp to match the brightness.

We looked at some SDR material (no HDR): Dark Knight returns (motorbike chase), Oblivion (library scene) and Paradise beach (sos flare scene).

Well it’s very hard to find some differences between the two. The contrast look almost the same with both projector exhibiting a very pleasing deep black.

The technicians before my arrival measured 18.000 contrast for Sony and about 19.000 contrast for Jvc (with both zoom lens at max and Jvc with manual iris full open), so they are very close.

I could really not see any significant difference in contrast. Maybe the Sony looked a little bit more contrasty in some scene while the Jvc exhibited a slightly better black floor, but again very very hard to notice.

Looking at some test pattern the Jvc seems to have a better lens but while watching movies the reality creation do a better job than the MPC.

Regarding colors Jvc has a wider gamut with the filter inserted, but this takes away so much light (20%) that is almost useless. Without the filter Sony regain the lead.

Fan noise is bearable on high lamp with Sony, I can not say the same with N7. In high lamp mode the fan is VERY noisy. Looks like an airplane during take off, great downside for me.

My wife that is ad “advanced” casual viewer could not see any difference at all between the two projectors.

A customer who visited the store one hour before me and had the same shootout bought the 695ES (they have the same price here in Europe).

I personally could not decide. They look almost the same and both projectors exhibit a stunning picture.

I was considering the Jvc because it has more calibration option but also because I like to run projectors in low lamp mode (for the noise). On my installation in low lamp mode I have the Sony with 47 Nits (that is ok now but when the lamp will lose light?) and I think I could get more than 60Nits with Jvc and maybe close a bit the manual iris (rising the contrast) and reopen it while the lamp lose light with use.

The fan noise scare me a lot, it is very noisy with Jvc while bearable on Sony when I watch HDR movie.

I was expecting to find a great difference between the two projectors instead it is a very tough choice.

I read a lot of bad comments in this forum regarding the poor black and contrast on Sony Projectors and after this shootout I can certainly say that they are unfounded and misleading.

Hope this helps.

Did you compare the dynamic contrast systems of both projectors?

What is the price difference.. if they both look the same i would just go with JVC plus it has the tone mapping..

I'm also have previously owned both Sony and JVC projectors, now I'm having Sony VW1100 and I ordered JVC RS3000 to replace it.
So, I never will be back to Sony because of their very dissapointing issue - so called SXRD degradation.
Sony VW1100 had a great picture quality out of the box, but few hundred lamp hours later contrast and colors start very noticealbe fading away, and after 1500 hours It become impossible to color calibrate the unit and I measured about 1500:1 native on/off contrast. Out of the box it was about 15000:1 native on/off with the same screen and enviroment.
As far is I know - Sony never admitted this issue, but I they replaced optical block of my unit twice(!), and now when It's out of warranty with the third optical block issue are the same.
Because of that looks like this problem affects most of the SXRD units, it's never been totally elliminated for the old projectors series, and there is no confidence that this degradation doesn't affect new models.

So, I think make sense to do second test after 1000-1500 lamp hours on both Sony and JVC units, maybe difference will be much bigger, specially in contrast.
Until the test like this - I'm not risking to purchase Sony projector and do not advise on anyone iether.

There is no price difference, both cost the same. I already own a 695ES and I have a Panasonic UB9000 for tone mapping.

I know, I had the same problem. The reseller swore to me that in the latest model they have not found anymore degradation.

Well, my dealer sworn to me that problem is solved after every optical block replacement)

How many lamp hours do you have at your 695ES?
There is no signs of degradation by now?

100 hours. Too soon maybe. My dealer has a lot of trade in for projectors so they measure every time the used projectors, from what they say they haven't seen anymore the degradation after the 3rd 4k Sony generation.

Also there is a potential risk that Jvc may have a similar problem...who knows?...after all it's their debut in the real 4k line.

In my case I start to notice changes at PQ about from 500 hours.

If I remember right - SXRD degradation issue also affected old Sony 1080p projectors, so I think that reason is not 4k resolution but a flаw at SXRD technology itself.
Also, I heard about this issue from VW5000 owners, don't know that generation It belongs to. Though maybe its not so dramatic like at VW1100.

JVC projectors from other side as far as I know always had stable image quality thru the years of usage.

This degradation are very unpleasant ussue, seeing the picture quality slowly drops, and also it is difficult to prove your dealer that something wrong with the unit (at my experience anyway).

I'm sincerely hope that Sony did solved that problem and your unit is allrigth.
I'll be very gratefull if you will give some more feedback after 1000-1500 hours.

Something does not add up. You said they measured 63 nits in high on the Sony and 62 nits in high on the JVC. So high lamp would match up well between them, but the comparison was made with Sony in high and JVC in low, so that brightness could match. Sounds like the JVC was at a severe disadvantage, running low lamp 50 nits vs 63 nits on the Sony.

That was not the question. He asked if the dynamic dimming system was turned on, on the JVC. You stated that it was on, on the Sony, but did not state if it was on, on the JVC. Also the JVC was measured in it's worst case.

I was also scratching my head on this one... Doesn't add up (for a fair head to head comparison).

JVC debuted their first native 4K projector at CEDIA in 208. Sold that model commercially for several years. Then at CEDIA 2016, JVC showed their second generation native 4K projector, RS4500. These new models are 3rd generation. None of JVC's have ever had a contrast degradation problem.

Yes you are right but as I wrote I was there to see the jvc in low lamp as I'd like to use it at home in that way, the Sony was too dimmed in low lamp (one reason I'd like to change it).

They measured native contrast. During vision they both had dynamic iris on (auto 2 for Jvc).

Also there is a potential risk that Jvc may have a similar problem...who knows?...after all it's their debut in the real 4k line.

Client's VPL-VW295ES showed blue panel degradation of SXRD after only 70 hours of operation.😧

Just some hypothetical observations? Has anyone seen degradation in the 4500, with laser as the lightsource? I can't remember any.
The chances of the panels being the same panels as in the 4500 are very high, although I don't know what the delta is between the static operating temps in the real world is.


Jeff Meier has a disclaimer on his page currently saying he will not work on Sony projectors or Samsung QLEDs:

"We do not work on Sony SXRD projection products at this time because of very poor product durability. We do not work on Samsung QLED displays."

If you trust this man as many have said, this post speak volumes based on that experience.

Hope this helps.
Oh no, a positive Sony review AND someone not praising the Emperor's new beamer.

By contrast, in the US - the Sony is $10,000 and the JVC is $8,000.

Only negative (not by me) I see brought up about the Sony was the degrading contrast and the guy you quoted said he experienced that with his earlier Sony projector. The rest of the questions were just trying to clarify if they were compared apples to apples. That is why he was asked about the dynamic iris on the JVC. Poster clarified dynamic iris was on. But poster did confirm that the JVC was in low lamp and the Sony was in high lamp. So not really an apples to apple comparison. Would have been nice if compared with both on high, along with what was done. I will say, if I had a VW695, I would not be replacing it with an NX7. Not enough difference to justify making that move. Both are really good projectors.

My 295ES has 80 hours already and no blue panel degradation. My VW40 and HW40ES showed some blue panel degradation after 200 hours, though.

I know people with 285s and 385s with more than 1500 hours operation and none of them have reported blue panel degradation.

If I had a 695 I would probably not replace it at this time with the N7, too similar. Contrast in only a few scenarios will be just about the only difference.

Forget about the tone mapping if you have the Panasonic it's going to be far superior anyway.
