Thanks for the feedback. I painted the wall behind my screen in a matte black but never really tested for light passthrough. I may try some material on the back to see if it further improves upon things. My real reason for the change though was considering the switch from 16:9 to 2:35 AR. I have a short throw though ~13.3Ft and have seen some posts with regard to the right size you could fill at that throw so need to test that out because I would not want to go below a 125" diagonal 2:35 screen. If it can't fill that, then I will go for a 120" 16:9 which I am sure I could fill at my throw.

Looks like using the zoom mode to scale to the full 17:9 panel it would work. Looking at this:

http://pro.jvc.com/pro/lens_calc/HTML/jvc_REF.html

If you put in a 2.35:1 125" screen you get 115x49" screen with a minimum throw of 164.96" or 13.75'. Which is just a bit more than you have. Since there is no indication whether it is using zoom to fill the 17:9 panel I switched the screen option to 17:9 and put in the 115" width (130" diagonal 17:9 screen). The minimum throw is now 154.33" or 12.86', which means that using panel zoom you should be able to fill the 125" scope screen.

Whether you want to use panel zoom or not is up to you. There seems to be some concerns over the mild scaling it uses. I use it on wider ARs and can detect no issues, just more light output. Personally I would use the panel zoom and get the 125" scope screen.

Wow. Thanks for the link and the feedback. I am going to test the 17:9 and zoom on my current screen to see if I notice any issues. I highly doubt I will notice enough of an image issue that would sway me from the larger scope screen. At this point the image is so good, depending on the content, that we are just floored with the quality and color this puts out. I am anxious to at least do a gamma calibration for now since I love the image, but know we can tweak that contract to get it even better.

I would be nervous about using all your throw margin on assuming you will use the full width mode. If you only have 13ft and the calc says ~12'10" then you only have 2" spare. JVC have said in various places that these numbers are a guide only, and even had written on one of the N5/N7 brochures recently that the guides for throw were +/- 5%. -5% would see you unable to fill the screen and you wouldn't have zoom mode to fall back on (as you've already used that also).

If you do go for it, I'd suggest telling the supplying dealer your throw requirements and making them stand behind the JVC numbers as being good to go. Then you are fully covered if you can't fill your screen.

Hi guys,

On my rs2000 I’m getting three or so defined white lines curved not quite semi circular that stand out on white backgrounds like clouds. Don’t see it on black background or when pic has color. Any ideas what this might be and is it something I need to be concerned about. Thanks!

Well I am going to go ahead and test the right size by trying the suggestions on my setup currently before I make any purchase. Granted I currently have a 110" 16:9 AR screen but I should be able to zoom on and test what size I get zoomed in using the 16:9, and 17:9 panel on 2:35 content to see where I land in terms of size. I can easily see the image on my walls if I throw up a solid white or colored image, and even just using the gridlines so I will test it out first for sure before I make any purchase. I can likely also get a sense of any scaling degradation to the image, at least for the portion thatch showing up on my current screen, to test out whether I like the zoom option. I appreciate the advice though on dealer requirements.

Bobof makes a very good point, however I think it was missed that you have 13.3' to work with. So that gives you a 4-6" margin to work with. Still close enough that putting the image up on the wall and actually measuring is definitely a good step.

Whenever I see ~ i disregard a bit. You can't include that measurement uncertainty in the JVC margin! (eg screen surface held away from wall, wall not straight, etc)

I think certainly if you can get the PJ first then just work out how the throw of the actual unit works (and still consider to allow for if your unit has to be exchanged and you get one which is still in spec but has less throw).

No that's true and mixing percentages/decimals with ft. doesn't end up all that accurate in a lot of cases. Just trying to be optimistic. Actually measuring is going to be the best method here. Just hope it works out.

I had this dilemma with my NX5 (achieveing the largest screen possible with my limited throw). I decided to leave about 5 inches of wiggle room. In the end, the NX5 was within an inch of what the online calculators said FWIW. I installed the projector, zoomed the image as large as possible from my mounting position (then made it perfectly rectangular), then shrunk the image by about 1" diagonally (for future wiggle room) and then built my custom screen to fit that size perfectly.

But I am certainly using the 17:9 zoom mode to get another 4-5 inches of width out of my screen which is nice.

It's one of those situations I don't think optimism has much place - but then my screen was significantly more money than my X7900 new, so there was no 2nd chance option.

oops... I still use the White Clipping Pattern from the HD set, not the UHD set.

The similar pattern is in:
01 Basic Setup Patterns
05 White Clipping
03 White Clipping 80-100%
It has what you need, unless you want to check light fall off at the 4 corners.

Well your bringing it to our attention so I would say its concerning you and that is all that matters. I am assuming that is in all content? The bottom line is you are still within the warranty I would guess so if you want to use your unit and see what happens you have plenty of time. If you want to call JVC about it, you can, which might lead to an exchange if you are in the USA. Uniformity issues are present in all display devises, it can be worse, could be better. Its a roll of the dice and that's the scary part.

I’m thinking of buying an NX7, but read a review that mentioned its upscaling left a bit to be desired. I watch a fair bit of sports and TV shows on the xfinity X1 platform on my Sony HW55es. Will the NX7 not perform well in this situation?

I have the NX7 and beside movies, the only tv I watch is sport. I can confirm that the NX7 have no problem at all with tv upscaling. Something better do exist I agree, but the upscaling on the JVC is not weak in any way,

Before the JVC I was using a Sony 885. Sony is supposed to have one of the best scaling and the difference between the Sony and JVC for sport viewing are very minor. A poor signal is a poor signal even the best scaler cannot do miracle.

Until TV signal get better we would have to live with that, but for your movies watching you will be in heaven because the JVC NX7 perform really well.

Thanks Cleveland for the thoughts. The thing is though, as I understand it, I don’t think it’s a uniformity problem——it’s actually three distinct clear white lines that show up (wish it were clearer in my pic, sorry) almost as though something in light path causes that pattern just on that one small part of screen. Otherwise I think my white and color field uniformity is pretty good. My dealer is coming to finish off a bit of work on my installation so I guess I will show him and go from there. Thanks again for your opinion on this.

I see like 4 or 5 lines in your photo. Its almost like some lens reflection (the lens is round). Is that centered on where your lens hits the screen? Is your lens dirty at all?

NVC's upscaler isn't terrible. It's just standard. That content will look "fine". It won't look 4K. I didn't think Sony's upscaler was any good either. I liked its reality creation processing but never thought it upscaled 1080p content to take on any aspects of 4K. A good upscaler can make 1080p content look a lot like 4K. So far, the only "good" upscaler I've ever seen is madVR's A/I Neural network trained upscaler.

The Dynamic Range Adjustment control does not touch the black level at all. See the measurements from Stacey Spears:

Thanks buddy...wholly crap...tooooo technical for me...what I found was as I adjusted the Dynamic range slider on the Panny 820, the black level rose around 3 or 4 as bar 68 became more visible...I have my JVC brightness set to -2 and contrast set to 7 (clips at 1000 nits according to R.Masciola patterns)...

Does any of this “sound” right?

Hi markmon

I too thought it looked like a lens reflection. Can’t tell just looking at the outer lens if it’s dirty or not. Everyone says to avoid cleaning outer lens if at all possible so I have avoided that so far. Do you think it would be worth giving the lens a cleaning and how would you suggest doing that safely. Thanks!

Did you confirm that it isn’t your screen? You probably did, but if you haven’t I’d recommend confirming that first before additional troubleshooting.

If you can pause an image that shows the issue, try flipping and/or inverting the image. That might help clarify if it is something in the lens (which shouldn’t change) or something in the image itself.

Level 68 becoming more visible is not unexpected when you increase D.R.A. I was replying to your original question, i.e., D.R.A. should not “raise black floor” which is level 64.
