Yow! The minimum spec'd *storage* temperature for the projector is 14 degrees! Normally I'd take it out of the box and let it acclimate for a few hours when it's merely "pretty cold" out but with that much of a temperature swing unless it's delivered from a heated truck I think I would leave it in the box to warm more slowly and maybe even go through a few stages - a few hours in an indoor room that's not fully warm but warmer than outside (like a mudroom, root cellar, or crawlspace) and then a few hours in the box within a normally heated part of the house, and then a few hours out of the box in the HT room but not powered up yet.

Be patient and let it stay in the sealed box for at least half a day to equalize to the room temperature. That way you will avoid condensation from forming on the inside of the projector and lense which could cause you problems.
^^ Matt’s idea sounds good too.

That's far too cold, I suggest you send it to me to look after it until summer-time

Thanks, patience it is. Mick, maybe I can come live at your place until summer and you can come look after the projector here for me.

-45 degrees? Brrrrrh.


You should check the package and the complete content. Is anything wet or clammy?


Then - to be on the safe side - it is a good idea to leave the N7 unused for an hour. And then it should be ok. to use it, I guess.

Well at least you have it figured out. Hard to push that much light and keep those blacks dark......

There are tons of factors here and 4k vs 1080p cannot really be isolated outside of running an HTPC for side-by-side comparisons.
The bitrate HAS to increase if there is more information (i.e. 4x more pixels to display). BUT, from what I have seen, UHD blu rays don't end up with 4x the bitrate of the 1080p counterpart, it is usually a lower number (typically I see about 2x the bitrate), meaning that for the number of pixels, there is more compression. So in effect, you have lowered the bitrate per pixels in typical UHD content.

You are correct, there is MUCH more to 4k UHD vs 1080p than just pixels, and that is part of my point. We aren't just talking about a 1080p static image vs the same image upscaled to 4k while sitting at a specific distance from the display. We are talking about more image information: a higher resolution source stock, a wider color gamut, and more dynamic light range, and combined this becomes far more than how well your eyes can resolve pixels from your seating distance.

When people are talking about "4k" in the context of a home theater, they are talking about the whole package, not just the number of pixels. So telling them that they will gain nothing by going to 4k because they don't sit a specific distance from the screen for the screen size is simply bad advice, IMHO. As a rough guideline, I buy it, but as a hard and fast rule, my eyes tell me it is wrong.

I do understand that at some point, higher resolution will become moot as you can no longer resolve more detail, but I don't think that point is the same for everyone, and I don't think it has anything to do with whether you can make out individual pixels. When I go to the eye doctor and read that bottom line, I can score 20/20 despite the fact that the letters are blurry. There is just enough detail that my brain can resolve it and determine what it is. It's still blurry though, and someone who also scores 20/20 could easily have better vision than me. Likewise, if I am trying to look at one pixel in 1080, and then the corresponding 4 pixels in 4k that make up the same dot, I wouldn't be able to tell you the difference between those pixels. But create a larger image from those pixels, and my brain starts to see the difference even though I couldn't spot a difference on the smaller scale. The point here is you can't just say that you have to sit close enough to be able to resolve the pixels in 1080p in order to be able to gain from 4k. You need to look at the images yourself and determine if you can or cannot see a difference.

You can all disagree, but I know what I can see, and the charts don't accurately represent whether it is "worth it" for me. YMMV.

If your microwave is large enough, put the NX7 in and set defrost at mid level for 10 minutes. J/k! I would just let it adjust to room temp for a half to full day.

Take it out of the box, turn the heat up to 74 degrees, and WAIT until the projector has totally come up to room temperature,otherwise you could end up with condensation INSIDE THE LENS (and elsewhere inside the projector) like another AVS member did when he got his new NX 9 and impatiently fired it up before the projector had time to properly warm up, reaclimate to room temperature!

Yes this really happened, he had a dull, fuzzy picture because of water condensation INSIDE THE LENS!

BE PATIENT, otherwise you can damage your brand new toy.

Again, take it OUT OF THE BOX so that it can warm up quicker and pet it warm up naturally, no hair dryers!

You need to double the contrast to really see a difference. So you will not see the difference between 130,000 and 160,000.

With a 120 degree temperature differential I would worry about condensation even if you don't turn it on. I've left a cell phone in a cold car overnight before and when I brought it in the house it immediately formed a layer of condensate on it's exterior. Even a glass of ice water forms condensation and that's with a differential of only ~40 degrees. The safest route to go here would be to leave it in the box to keep moisture out and just wait longer for it to warm up.

This isn't a valid comparison. UHD is using the more efficient H265 video codec vs H264 on Blu Ray. This bump in efficiency means you can have the same or better quality using less bandwidth. It's the same reason Blu Ray switched to H264 and VC1 from MPEG-2 used on DVD. You're not comparing apples to apples. You need someone well versed in one codec vs. the other to really say if UHD is actually compressing the information more.

Yes condensation will be an issue...put the box in one of those big contractor trash bags and tap it shut to keep out the moist air in your house out of the box. Let it sit overnight to acclimate.

Well, anamorphic lenses never wear out, so once you buy a good one, you are set pretty much for life.

Don't get me wrong the Sony is a nice picture but I think with the auto-tone mapping etc we feel the the overall picture is better. BUT it was not in our environment so totally subjective. Price is a whole other issue and the JVC for us was a much better value.

You aren't comparing apples to apples when going from 1080p to 4k in ANY regard, which is part of the reason you can't just boil it all down to distance vs screen size for a given resolution. You will always be comparing 1080p streamed to 4k streamed, or 1080p blu ray to 4k UHD blu ray, and that is as close to "apples to apples" as you can get.

To your point, I might argue: if you can display 4x the information at only 2x the bitrate of data, then there is more compression. But also to your point, the question there would be whether the compression is lossy or not. H265 is not a lossless compression, but it is probably better than H264 at the same bitrate. Either way, I view the content as it is available - exactly as it comes in the blu ray disc. So whether the higher bitrate adds to the sharpness or not is irrelevant - the fact is, the chart is telling me that since I sit too far back from my 65", it is not worth upgrading to 4k UHD, and I don't see it that way at all. The chart is wrong (for me) because I DO see a significant difference that adds to the quality of the media, and enough of a difference to warrant the cost of a 4k display, media player, HDMI cables, and a source that is 4k.

The charts are a guideline, that is all. And just because one person doesn't see a benefit to higher resolution unless they are 3 inches away from the screen doesn't mean the next person won't either. Take the advice you get with a grain of salt and if at all possible, go see for yourself before making a decision. That's all I am saying here.

I disagree with this, the projector is in a box surrounded by plastic that will do a relatively good job of keeping the humidity inside the plastic fairly stable. PLUS, there is a BIG packet of silica pellets that will absorb moisture and keep the humidity down. If you take it out of the box in your humid room while the lens and circuit boards are cold, they will instantly start forming condensation.

Leave it in the box to warm up before taking it out. At least a few hours, maybe longer if it is that cold.

If the Delivery Truck wasn't heated, and at -45 degrees there was any Wetness or Clamminess, it would be because they packed it in Anti-Freeze.



The PJ needs to acclimate for at least 24 hours in it's sealed box at room temperature. Even then, once unpacked (...be careful with that Ice Pick...) it should be left unused for another 24 hours in a dry, non-humid location because the interior Circuit Boards and Lycos Panels will still be pretty well sealed up and insulated.

I was only referring to the codec/bitrate part of your post (thus I didn't quote the whole thing). I'm not trying to debate the validity of the chart you're referring to or whether you see a benefit. My comment was to point out that your statement that UHD having 4 times the pixels but only twice the bitrate of Blu Ray means that it was more compressed (thus suffering from more compression artifacts) isn't necessarily accurate. H265 is definitely more efficient. Whether that efficiency is enough to offset the bandwidth available, I can't say (I'm not a compressionist). My experience is that UHD Blu Ray has always looked better than it's SD counterpart and I have not observed more compression artifacts.

Tell that to the AVS member who reported a "fuzzy", opaque image due to condensation IN THE LENS of his brand new $13,000 NX9 after basically following your advice and not letting his projector naturally come up to room temperature.

Leave it in the box to warm up before taking it out. At least a few hours, maybe longer if it is that cold.
Sound advice, makes sense, I stand corrected.

I think maybe you are reading a bit too quickly or responding to someone else. I am very much in the "leave it in the box for many hours until it has equalized with indoor temps" camp.

Seems like a very 'apparant' problem to ship the projectors with.
Fixes for stuff like this does not happen overnight. Made JVC USA aware. They in turn will confirm the problem. Then problem has to be presented to JVC Japan engineers. Then solution has to be engineered and update issued.

I let my RS3000 sit in the house for a full day before bothering with powering it up at all. You will kick yourself if something goes wrong in not waiting. Everyone has waited a long time for these so how bad is waiting one day really

Forgot that JVC Japan holds all the strings.

I hope JVC USA at least acknowledges the issue - it would be unfortunate if they didn’t

I have an RS2000 sitting in front of me ready to be powered on in a few hours.

Warning! Dumbass questions follow!

1. What are the first 4 or five things I should check on it?

2. I notice people have been indicating that they needing to adjust a specific color pixel left/right/up/down etc. What is that in reference to? How do I check that and how do I adjust that?

3. Convergence? Wait 30 minutes with the unit on to check it? How?

4. Something specific I should pick up for test patterns?

5. Auto 1 or 2 on the DI shows yellowing?

Wow! They actually do deliveries at -45? Here in Minnesota, the post office didn't send their carriers out on the day we reached -30.

1. Put on the Lens adjustment on your screen. Turn off CMD, Turn on Auto Aperture - Auto 2 and then play your favorite movie and watch it - without a care in the world :-)

If you are playing HDR go to Gamma setting and based on your screen adjust Auto tone map (if larger than 100 inch 1 gain move slider to right, if smaller or higher gain move to left)

2 and 3 are the same: let the PJ run for 30 minutes go to INSTALLATION menu - select pixel adjust - Select Whole screen. It will show a white pattern. Pixel peep at the screen start with the center and see if you see any red or blue lines if you do make a few clicks on the remote to adjust. Then move to the sides and see if there are any major variances.

4. There are several patterns- I picked up the free Mehanik HDR patterns just for kicks but I find that even without any adjustments the picture is quite good.

5. Yes with DI engaged there is a yellow tint - best not to check it because is you see it once you can’t unsee it
