Just to inform people my N5 might also be one of the vertical stripes bug victim. Fw is 2.05 OOB.

However, a little different story how bug was shown. After 27 hrs in the middle of GoT, latest episode, while streaming from HBO app in Samsung S4 tablet green pixels started to show in picture and finally larger areas of greenish blocks corrupted the picture. I opened main menu and it started to show stripes, bluish and pink stripes in menu window and menu itself was also vibrating rapidly. No stripes in picture itself, only those green pixels.
Next I only changed iris from auto2 to manual which didn't help. Power cycle did help and rewatching problematic point in the episode did not show any corruption.

I have Ruipro 10m cable between N5 and Denon AVR-X4500H. Picture mode was in user mode, color profile SDR709 with custom gamma 2.3, brightness -3, iris auto 2, -9, low lamp. Info window showed 2160p,30fps and RGB 8bit. Upscaling in AVR was disabled.

This was first sign of any failure or bug. I think it was not the case of overheating or problem with the cable or in signal path. I had projector on for couple of hours before it happened. Day before it was on for much longer period of time.

Otherwise I am quite satisfied with this projector although it does not have the best convergence. Projector has also so many options that it takes a lot of work to get picture quality right for multiple sources I have. And I have not yet touched 3D.

7.1.4 Dolby Atmos system: Denon AVR-X4500H, Sony DA2400ES(for back Atmos speakers), 2xMonitor Audio Silver RS6, 2xRS1, 2xRadius 90, Radius 225, 4xDali Alteco C-1, BK XLS200, JVC N5BE with Ruipro 10m fibre HDMI cable, Grandview Fixed 4K Edge 100" (1.0), Panasonic DP-UB824, Sony BDP-S790, Topfield cable FHD box, old Sony FHD 46" TV, Denon DP-450USB, Logitech Harmony Hub + Samsung Galaxy S4 TAB, Asus RT-AC68U router

Same bulb, but new housing. I believe you still could remove the bulb from the current housing and place it in the new one.

That makes sense now......Might be easier just to ditch the mount all together now...

That sounds very similar to what I've experience. i've been talking with JVC and they're sending me a replacement since it's still happening with the newer 2.05 software. I'm still not convinced that it's not just a software bug (and not related the hardware of specific units).

I noticed that you use a Denon receiver (as do I) and I'm curious if those that have experienced this issue are using a Denon or Marantz as well. If anything, at least we can rule that out.

Im in Canada, Seymour is almost 3x the cost as I can get the elunevision for. So, its not even a consideration at this point.
There are not a ton of options for us Canucks.
I can get a 135" motorized elunevision for 45% off retail, so theres nothing that will come close to that price/performance for me that I can find.

I have over 200 hours on my nx5 and not a single glitch! Although I’m not using an hdmi pre pro or receiver.
The nx5 is connected to my oppo 205.

Hey guys, for the Chief RPA-281 mount, do I just get that or is the plate connector separate and in addition to that?

Thanks

I just got my plate for my nx5, not cheap but I’ve been using the same mount for 3 different pjs and many years


I will say that I found the screws that were provided with the plate seemed too short and made me feel uncomfortable with all that weight but a trip to the hardware store fixed that!

Perfect thank you. Do you know if it is centred for the projector? I have a mount right now that I don’t really trust because it is very hard to centre it to the projector so that it mounts straight. Right now it tilts down because the centre of gravity is off. Plus it just doesn’t seem strong enough.

Thanks for your help.

Thank you for that. Would you be able to answer my centre of gravity question as well? It is greatly appreciated.

Issue with Dolby Vision Discs

I received my NX5 this week and have been watching some 4K films on Apple TV and on my Oppo player. They all look amazing! Today I put in a Dolby Vision disc and the colors and image is distorted (see screen shot attached). Does anyone know what settings I have to adjust in the NX5 or in the Oppo to get the image to display correctly. I tried a couple of Dolby Vision discs and they all had the same problem. Thanks!

I would suggest you try XYscreens. IMO it’s much better because of higher gain

I've found the RPA to be solid mount with good centering of the mass below the pivot points.

Is this an Oppo 203 or 205? If so, check Setup Menu -> HDR Setting -> HDR

you will see Auto, Forced, Off, Strip Metadata, Dolby Vision

Which setting is the default?

Who said anything about 135" wide? I just saw '135"' or '120"' mentioned. Screen measurements always indicate diagonal.

I can't find a pic of your setup but should be something like this without AT screen.
Maybe in reality it's not bad but the closer you sit the AT screen is more likely needed to keep the middle of the screen as close to your eye level as possible to avoid this looking up situation.

Any owner here with AT screen who's sitting relatively close?
I sit 7 feet from a 135" screen. Screen is 4" from ceiling. Even on scope movies, I move the image to the top, not the bottom. This allows me to recline on my recliner, which points me more towards the ceiling.

Wow that close, then you really can't have AT screen not just because of the weaves but also with low screen position your head might block the projection. It's all about personal preference, also sitting like that the higher position make sense

But good to know that there are many big AT screen owners here so this N series is bright enough for 130+ inch size.

Since the Jvc has no Dolby Vision compatibility i think you may be using some sort of "forced" DV output that cause the issue. Just disable DV or put it on auto and it should be fine showing the hdr layer.

I'm convinced that series N has software issues. I'm also convinced that Jvc will iron out all those issues, eventually. The fact is that issues are so random and apparently not related to a specific enviroment tha is very hard to trace and reproduce. I've done extensive tests to find out what was causing the blue vertical bars and similar. I think that is something related to CMD and/or low latency setting. For some reason the low latency is on by default but apart from the fact that i can't see no use for normal movie viewing i'm pretty sure is the key factor or at least one of the key factors in causing the random issues. Since i have disabled all cmd options including low latency and motion enhance i've had zero issues.

If I remember correctly (I need to check this later) I have Motion Enhance set to low, CMD off and low latency off. However, I tried CMD setting 'low' during streaming but that was at the start of the episode, some 30-40 min earlier. I disabled it after noticing some artifacts (not green pixels). If glitch happens again I'll try the following in the order

1. change the input from HDMI1 to HDMI2 in projector. If no help then
2. disconnect HDMI cable from the projector
3. bypass AVR and connect source directly to projector

Hopefully I can check this way my AVR is not the culprit. I checked earlier that upscaling in AVR did not cause any detrimental effects on PQ but anyhow I disabled it when using projector.I use upscaling with my FullHD TV to get 1080p resolution (source 1080i or lower).

7.1.4 Dolby Atmos system: Denon AVR-X4500H, Sony DA2400ES(for back Atmos speakers), 2xMonitor Audio Silver RS6, 2xRS1, 2xRadius 90, Radius 225, 4xDali Alteco C-1, BK XLS200, JVC N5BE with Ruipro 10m fibre HDMI cable, Grandview Fixed 4K Edge 100" (1.0), Panasonic DP-UB824, Sony BDP-S790, Topfield cable FHD box, old Sony FHD 46" TV, Denon DP-450USB, Logitech Harmony Hub + Samsung Galaxy S4 TAB, Asus RT-AC68U router

Your specific issue seems related to source and/or connections. IF we're talking of the well known issues changing input, disconnecting cables and/or bypass avr will not change anything. Anyway disable enahnce too in cmd and try again.

I have the 203. I'll check the settings when I'm home tonight. Before I got the NX5 I had the Epson 5040UB and it played the disc without any issues.

Thanks! I'll try this when I get home tonight.

That's encouraging. Makes me think it might be more of a compatibility issue or something.

I've done extensive tests to find out what was causing the blue vertical bars and similar. I think that is something related to CMD and/or low latency setting. For some reason the low latency is on by default but apart from the fact that i can't see no use for normal movie viewing i'm pretty sure is the key factor or at least one of the key factors in causing the random issues. Since i have disabled all cmd options including low latency and motion enhance i've had zero issues.
Unfortunately, I've had low latency and cmd turned off since I first powered up the projector and I've still been victim to the issue. I agree, I think it's a software issue so hopefully they'll get it worked out sooner than later. Btw, are you using a receiver for the HDMI switching? If so, what brand?

Low latency needs to be switched ON, not off, in order to disable all CMD processing. Motion enhanced should also be switched off.

Not sure if this is enough to prevent the issue from happening, but this is what you want if you want to prevent any unwanted processing.

Whatever the size, my comments still stand. I was asking "are you sure?" about your suggestion for two center speakers to have an educated discussion about the pros and cons of the approach. I didn't expect it to be shut down like that. Oh well, I will look elsewhere for friendly educational discussions...
