I am trying to load up the Quick Brown Fox test pattern my current projector (a JVC RS-1). Just as a matter of curiosity (and boredom) I wanted to see what it looked like before my NX7 arrives so I could do a comparison. But I can't seem to get it to display on my current projector.

I have a Panasonic UB820 player and I inserted a USB drive containing the pattern into the player. Initially, I had downloaded form this site (I think from Arrow-AV's signature) the pattern formatted as a PNG file. But then I discovered that the UB820 will not play a PNG file on the USB, so I converted it to a JPG file using the Paint program in Windows. That didn't work. So I then converted it to a JPG file using an online PNG to JPG file convertor. It still doesn't work. The player just says something like it cannot play this format or cannot play this file There are other JPG files on the same USB drive display that display just fine.

Anybody got any ideas on how to get this test pattern to display? Thanks in advance for your help.

So it might be a line wide issue- hopefully something that is firmware fixable - because that panel itself is able to display great quality whites.

I will also call up JVC customer care and ask them about it.

In the meantime if other NX series owners could check for this that would be super helpful

There is indeed some yellowish tint on white subtitles against a black backdrop whenever I invoke the projector on screen menu layer. But once I exit the menu, the yellow tint is gone and back to white. I’m not sure whether that counts? Take note I have experience or come across yellow tint on the white subtitles during normal movie playback.

It may because of the resolution of the image. You'll probably need a 1920x1080 version of that that file because the one floating around here has a resolution of 3840x2160 .

EDIT: It was the resizing that did it.

A 1080p version of that image will counter act the benefits of the comparison. I guess you could load the 4K version into photoshop and resize it to 1920x1080 and save that image and try to display it. You don't want the one created for 1080p though in this comparison.

That's what I did. I was just curious and wanted to get a rough idea of how my current projector handled the pattern. Didn't feel like watching TV or a movie tonight.

I use eshift on with my Xbox one X. On white backgrounds, everything is pure white. Regardless of eshift on or off.

Not sure how to produce this yellow effect.

Mine has been booting normally since the 1.20 update. Mike also helped me, late on Saturday night, to get my projector back up and running after I got confused by the update behavior not matching the docs or the 1.17 update. Very grateful for the help at such an off hour! I know where I’ll be getting my next projector!

I also haven’t noticed any changes in PQ with the update (the picture blew me away before the update, so not sure I would notice blow you away + 1). I did have the iris lock up with the 1.17 firmware, which was resolved by a power cycle. Maybe they resolved that, but it only happened once in about 150 hours of use.

Its very hard to convert to jpg without compression artefacts. Note on your jpg version, there are compression artefacts on the red and blue lines.

HELP!!! RS3000/NX9 vs RS2000/NX7 vs RS1000/NX5?

I started a new thread, but I realize most people are just following this thread, as I am. I've tried to shorten this version of the post.

Ordered a JVC DLA-NX7 a week ago, still have 1-2 wk to wait. Now I'm wondering, should I have spent more for the RS3000/NX9 OR saved money and gotten the RS1000/NX5? I'm looking for the best bang for the buck.

1. RS3000/NX9 owners: value is subjective, but what made you buy the RS3000/DLA-NX9 for thousands more than the RS2000/DLA-NX7? I want the best blacks and HDR possible, but is that worth $6-8K more? (I have a 156" scope screen so I need a lot of light).

2. RS2000/NX7 owners: I read that the NX7 and NX5 are equal in brightness AND both have DI. Is the NX7's higher CR noticeable? Or should I get the NX5 and spend the savings on an anamorphic lens (obviously not the $8K Panamorph DCR)?

Thanks in advance.

JVC DLA-NX9 / 156" 2.4:1 CIH Seymour AT screen / Marantz AV7704 11.2 / Yamaha MX-A5000 11-ch amp
HTPC MadVR RTX 2080 / 24TB PMS Server (direct UHD rips)
Adam A8X monitor LCR / RBH A-610 x 8 / Kef Ci160ER x 4 / HSU ULS-15
Secondary: Samsung UN82MU8000 / Marantz NR1607 AVR / Kef Q150 + Minx Min 10 / SVS SB-2000

I preordered an RS3000, then splurged and got an RS4500 instead. That being said, coming back into this again, I might consider just an RS2000. I think it'll have better blacks than the RS1000 and it at least has the HDR filter for BT2020 if you should want to use it. It has the additional lamp iris that the RS1000 doesn't have. It advertises *double* the native contrast ratio so if you care about better blacks, it seems that is worth the $2k over the RS1000.

The RS3000, lens is going to be better. But as an RS4500 owner, I can tell you that even 7 feet away from the screen you may not notice the difference in the RS2000 to RS3000 lens.

I don't have any buyer's remorse for the RS4500. I love solid state dimming. But I feel the NX7 / RS2000 is probably the best bang for the buck.

Maybe you remember that I had some noise from the DI on my N7 (loud clicking sound). I was expecting the replacement unit last week, but since it did not arrive and I didnt want to spend a weekend with a 42" telly, I unpacked the N7 and put it temporarily on the living room table. Guess what, after about 15 hours of usage during the weekend, there was not a single noise from the DI. Now this makes me suspect the noise developed when it was ceiling mounted. I am stumped Yes the unit was power cycled multiple times and firmware re-loaded. I still believe there is an issue with the DI on my unit, maybe the DI internal parts were not seated correctly or some other thing mechanical. New unit should be here wednesday and I will replace it, just to make sure.

Still makes we wonder, how many NX7 / NX9 with DI "noise" has their units ceiling mounted?

Hey Drem,
Would be interesting to see what happens if you are able to 'invert' your unit on the table, & see if the issue returns? That would possibly indicate a problem with running it inverted, as it would be when ceiling-mounted...
Just a thought.

Yes I was planning on trying that, but the unit is now packed into the box again.

WHAT?

Next thing we know, you're gonna give a 665es another look!

No? I go to far?

Ok, but can't fault one noticing your progress.

It advertises *double* the native contrast ratio so if you care about better blacks, it seems that is worth the $2k over the RS1000.

The RS3000, lens is going to be better. But as an RS4500 owner, I can tell you that even 7 feet away from the screen you may not notice the difference in the RS2000 to RS3000 lens.

I don't have any buyer's remorse for the RS4500. I love solid state dimming. But I feel the NX7 / RS2000 is probably the best bang for the buck.
Have a question that I thought you may be able to answer. What exactly is "Native" contrast? Is that measured with no iris in place just the difference between the blackest black level and the brightest white level? In other words if you took a RS1000 and a RS2000 and didn't use the iris would the RS2000 have double the native contrast of the RS1000? Or is native contrast figured by measuring the brightest level possible using no iris against the blackest level possible with iris in maximum position?
The reason I'm asking this is for playing 4K HDR it seems a lot of owners are using no manual iris to obtain the highest lumens possible and letting the lens iris work its magic in dynamic mode. It seems if this is the case that there might be very little difference playing 4K HDR between a 1000 and a 2000 as the 2000 will not be using its lamp iris and both will be using the lens iris dynamically.
I'm sure we'll know more when Arrow gets all the measurements but I was curious how the native contrast number was determined. No iris or No iris against the maximum closed down iris possible which obviously would give the 2000 the double contrast figure as it has a second iris to further dim the black level.

It's a fair point. JVC said sometime ago that the difference between the native contrast of the RS2000 and RS1000 was *not* just the lamp iris. I guess we will need to see open iris measurements to confirm.

But yes, I would say native contrast is the difference between blackest black and whitest white on a given iris setting where the iris does not change between the two measurements.

No iris (or open iris) white against fully clamped down iris would be considered dynamic contrast.

Going all the way back to the X3/X7/X9 range Cine4Home reported differences in the selection of devices based on the behaviour of the wire grid polarisers.
From: http://www.cine4home.de/tests/projek...chsspecial.htm
Quote:
1.6.1 Upgraded WireGrids
However, as with all optical components, there is a margin for perfection in production, that is, some WireGrids work a bit more precisely than others. JVC took advantage of this fact and chooses Quality Assurance: WireGrids, which allow a minimum native token ratio of 50,000: 1, qualify for inclusion in the X3 model, starting at 70,000: 1 for the X7 and only starting at the magic limit from 100,000: 1 for the X9.

It is easy to see that the compensation requirements for the WireGrids of the X7 models are significantly higher and that of the X9 even higher and it is correspondingly harder to meet these demands in production. And as with all goods, the closer the manufacturing precision is to the technically feasible maximum, the higher the committees, the lower the possible number of pieces, the higher the manufacturing costs.

I was looking at this thread about JVC iris operation started by Mozen a few years ago and got me thinking:

https://www.avsforum.com/forum/24-di...n-writeup.html

It would seem that the iris can close further than the -15 position when it uses the dynamic function so perhaps that is where the additional 10x factor for dynamic contrast comes from. Just trying to get lowdown on how these contrast numbers are arrived at.

Interesting, so if that is the case of a difference in chip yields then you really have no idea what you are getting except minimum allowed performance. If the new chips have a good yield there may not be large differences possibly.
I guess the counter to that is where the top tier projector from prior generations that supposedly had hand selected parts did not always perform as such.
