I'm talking with my dealer now, but yeah, i'm gonna push for a replacement or a swap. This is kind of a bummer, after re-doing the panel alignment and focus last night, i am really happy with the picture it's throwing. Lucy, especially the beginning sequence with the guy in the suit, is razor sharp.

btw, I am also using a peerless mount, there is definitely some movement with it. I am using a fairly long extension. I'm gonna look into alternate mounting solutions and possibly build a ceiling box, shelf for it instead. It's been really windy in the Dallas area these past few days. when the wind kicks up it must be shaking the house very slightly because when it does i can see some slight movement on the projected image. I might look into a chief mount, but i really love the peerless adjustment knobs. It makes setup such a breeze. 50lbs is definitely its limit though.

I honestly don't know what these are. I had no pixel alignment 'problem' .

Red was shifted by one pixel and all it took was one nudge in area alignment to fix this.

There is no DI now atleast not that I have noticed while in operation. Only time there is a noise is when HDR kicks in or when I changed the manual iris (and going to Auto afterwards)

That means that it isn't inherent within the projectors, which is good. However, the recurrences suggest a slight quality control issue and repairs and exchanges for quite a few folks.

If all's in order by summer, I might have a decision to make on this one.

Has this been demonstrated objectively anywhere, one way or the other?
JVC uses it when going around doing RS4500 demos.

Personally I don't like flush mounting. I like a little space above my projectors. I'd get a CMA101 ceiling plate and a 1 1/2" threaded " close nipple " from a hardware store or plumbing supply. That gives you a little space above for air circulation but only costs maybe 1 1/2" - 2".

Thanks for the reply, Mike. I think you had alluded to this in prior posts on this topic, which is what I was vaguely remembering.

Dominic and I had an exchange in the 20LTD thread that he linked to above, which does demonstrate fairly definitively that making zonal adjustments can negatively impact the picture quality, at least when viewing test patterns. Dominic indicated there that "To be fair, I can’t say I’ve seen the issue when watching movies."

To which I responded:

"It then makes me wonder: if the initial misalignment (that using zone adjustments is intended to correct) is also not evident when watching actual content (and I understand that isn't what you just said, but might be the case), and the negative effects of zonal adjustments to the misalignment are not apparent, then are we just chasing our tails??

In other words, do these adjustments, whose need is determined by 'pixel-peeping,' have any net positive impact on picture quality when viewing actual content? Or does it just satisfy the OCD that so many of us (myself included!) suffer from?"

Who knows??

I strongly agree with you...and with a NX9 going up in the air on Friday, I'm hoping I'll get a pass on that issue. If not, the individual concerned will not tolerate such since that pricey big girl will almost be directly over the seating (just ahead actually).
I received my RS3000 late last week and have only spent about 8 hours viewing it. My box was not double boxed, however all the Styrofoam caps were intact and it appears that the projector didn't take any rear hard impacts. My PJ also didn't have to travel as far since I'm out in Colorado and not the east coast. I also haven't heard any clicking of the iris and I've operated the PJ in both Auto 1 and Auto 2. When I have more time, I plan on taking a closer look at panel alignment. So far what I've seen without taking into account warmup, is a very slight misalignment that can be seen when up extremely close to the screen. My projector also came preloaded with FW 1.17. Hopefully the noise some are hearing is not an indication of a common issue with the iris.

I believe the RPA version (pictured) can also be used for flush mount. Note that there are 4 holes surrounding the threaded section. I believe that 4 bolts go through these holes into whatever is above.

This mount looks like it is really easy to adjust. I have the cheaper version (RPM?) which is more difficult to adjust. If I was doing it now, I would probably get this version, but it's not a great problem to adjust the RPM version and once it's done I never have to mess with it as long as it's a solid flush mount. (A pole mount, especially with a longer pole, might be a different story.)

It does. I used the test pictures from these test patterns - https://www.diversifiedvideosolution...uhdhdr-10.html flipped convergence correction on and off, and I could see the difference from my seat. I have good vision. Now, if you can't see a difference from your seat, then one can argue not to use convergence correction.

On that same subject, my RS4500 displays the 4K single pixel test pattern perfectly. But when I scale video to 4096 x 2106, that mangles the test pattern. Makes it look closer to what the Optoma UHD60 displays. However, 4K movies scaled to 4096 and watched with the DCR lens look stupendous. Better than without the scaling and lens. So, at the end of the day, I really only care what the final result on the screen looks like.

I'm at a point in life where I could, but I know me, and I'd sit there every movie stewing over "How much did I pay for this stupid thing?"

I look back on my original projectors - I had an Infocus, then an Optoma H79 originally that I actually bought from AVS - that couldn't even remotely compare to a blu ray image.

My rs620 throws an absolutely stunning image beyond what I could have imagined 15 years ago, and now thes new NX machines are tickling my interest.

It never ends.

I let it settle a bit more today and was able to set red pixel adjust to 0, but blue needed -2V. I didn't look super nitpicky but to my eyes this was pretty good across the entire image. Granted I've now installed my Paladin DCR so some adjustment may be due to the lens?

Oops, read too fast. Thought "feet" when I saw "meters."

Yeah, that's a pretty good poke, but I'd bet there's some cable that can handle it. Did you get recommendations from the Mike or other AVS guys here? PM them.

I would only use 3/4" plywood for the shelf and also install a piece of 1x2 or trim on the front edge to reinforce the shelf.

As someone else just noted, please share your thoughts on the image. Are you loving it? Any initial buyers remorse?

Yup, i promised myself i wouldn't pixel peep and yet, here i am, obsessing over test patterns because "i paid x amount for this machine, it better be perfect, blah blah blah". And then i actually watched some content after getting everything setup and i was amazed. Honestly, i'm surprised that even 4500's have panel alignment issues, even if it's minimal. My theory is that the panels are perfect after manufacturing and it just gets banged around during shipping. I'm going to assume that the super high end gear like the 100K+ christie projectors, probably have mechanical panel alignment that can be done on the unit itself or from a service menu.

I hope all with the clicking noise reports this to their dealer / JVC so it comes to light. My dealer is still waiting a reply from JVC.

Lucy, especially the beginning sequence with the guy in the suit, is razor sharp.

I checked my RS3000 while standing on a stool so my head is directly below it. I'm watching the DI change (both Auto 1 and Auto 2) as I go from dark to a fairly bright scene. I can hear the fan (low lamp) and I hear absolutely NOTHING besides that.

Coming from a 990, here are my thoughts:

- Better motion handling during panning scenes
- no black crush
- 990 had deeper blacks but less shadow detail
- Amazing color and image sharpness
- NO lamp flicker that i can tell
- Auto one mapping works reall well, even when using atv4k/infuse or netflix/amazon.
- improved sync times.
- calmer image
- More brightness
- No more lightpath fan noise, or at least its volume has been greatly reduced.
- No eshift noise if you turn off 8k, which you should, but even with it on, the noise is less than my 990.

Con's
- It's a heavy beast. Definitely a two person job to mount unless you are The Rock or John Cena.
- You will pixel peep because all the cool kids are doing so these days.

I'm projecting onto a 135" 16:9 elite screens cinewhite with 1.1 gain. Batcave that is painted with SW tricorn black superpaint flat, no velvet, yet. I do plan on adding black velvet to my room. THis should improve contrast quite a bit more.

Oh I'm loving this machine. For me its like a new set of speakers that are revealing things in content you thought you were already familiar with. I have a new Ruipro fiber cable arriving today to replace what appears to be a defective Ruipro cable. I've had to you use HDMI cables that do not allow this to display above 1080P/60Hz. I hope to utilize its full capability tonight in some UHD content. Even at 1080P, the image looks fantastic compared to my Runco Video Extreme series 3-chip DLP it replaced. My Runco must have way higher fan noise than the JVC because I really cannot hear the JVC much at all and I am having to run it in high altitude mode since I'm at 7,000 feet. Love it and can't wait to get more time with it. My wife also without hesitation saw the difference and she is a casual viewer.

I would only use 3/4" plywood for the shelf and also install a piece of 1x2 or trim on the front edge to reinforce the shelf.

Yeah, that's a pretty good poke, but I'd bet there's some cable that can handle it. Did you get recommendations from the Mike or other AVS guys here? PM them.
I didn't check with anyone in particular from AVS. I thought I reviewed on AVS a posting that had many people testing HDMI cables at various lengths and using specific content to test the cables and verify that they are stable and do indeed work for all that the RS3000 will require of it.

I might look into a chief mount, but i really love the peerless adjustment knobs. It makes setup such a breeze. 50lbs is definitely its limit though.
The better Chief mount has gear adjustment. You loosen one set screw and stick a #2 phillips screw driver in the hole and turn the gear. Then tighten down the set screw.
