Very similar. Same generation just refined for two more years?

I'm still not chomping at the bit for another projector - it would be very hard for me to give up the contrast/black levels I'm used to.
imo it still is. I recently calibrated and measured the contrast with a Minolta T10

wide open iris Native 48K:1 and 500K+:1 with the DI. When I had the RS2000 here, the DI was in the ~220K:1 range, the dynamic iris doesn't close as much as the RS600 (by quite a bit) and left me wanting more in the low and very low APL scenes. The reduced clamping of the DI in the native models was done to reduce pumping but I don't have any concerns with the RS600 DI and use it all the time with SDR and HDR content. It digs down deep when it needs to for a convincing black floor in the very low APL scenes.

This is still one of my favorites over the years and picked up a low hour spare in case something happens to it.



There are many years of life left in these projectors

Wow, so is that significantly more than the 500?

hi, not really, i've seen RS500's in the 40K-43K:1 range and ~430-450K:1 DI. It really depends on the sample quality of the specific unit which can vary quite a bit sometimes.

These RS600's are very nice copies. excellent focus across the entire screen, no convergence corrections needed and very good panel uniformity.

Thanks zombie, that's what I figured.


I love the automatic iris on the RS600. I can certainly see it working in certain conditions, especially some credits, but otherwise it does a really nice job. If you have a night scene with some high contrast elements the contrast effect makes the black level appear deep. Then if that's followed by a low APL night shot, the lack of contrast without a dynamic iris reveals higher black levels to the eye. But with the dynamic iris, it closes down making the black levels deeper again. The effect is that deep black levels appear more consistent across varying scenes, with an over all impression of better black levels. I watch lots of sci-fi and horror movies, so the contrast and dynamic iris of the RS600 reap very nice benefits.

So I was debating too weather ‘upgrade’ to a RS500 from a 420. In a not dedicated room with white walls but completely dark what difference I would definitely see between the two let’s say when both properly calibrated and with the lens wide open in both? I am trying to understand weather keep the 420 or try the 500. Any suggestions? Thank you very much. Ps. I am not a gamer and I can calibrate the projector

Which has more hours on it? Any repairs on either? How much to upgrade?

What are the trade offs?

What other upgrades are on the table? Paint? A second sub? Room treatments?

It’s not a big upgrade so there are possibly far more impactful ways to spend a thousand dollars.

The 500 has almost 600 hours on the original first lamp. It has also custom curves upload in. But since I am using a Panasonic player 420 I don’t plan to use the high lamp on the jvc. In this way I could only keep lens wide open but in low lamp for SDR2020 ‘mapped’ by the player. In other words I think I may have much more contrast even in a living room environment. The point is will I notice this difference? Of course not switching on HDR mode high lamp on the 500 will exclude also the filter which is actually one of the pros of the 500 compared to the 420

It's weird to me to again hear this... just going by the stated specs, it should be a significant improvement in picture quality.

Custom curves are great. But the curve that works best in one room, for one screen size and one particular amount of gain, and even one particular amount of white ceilings, is going to be different than the curve that works in another room, with a different screen size, with a different screen gain, etc. and it drifts over the life of the bulb (gamma droop).

And of course if you map to SDR then you won’t use the custom curve, you’ll just use a regular SDR gamma like 2.4 or 1886 etc.

And if you want to use low lamp mode then my experience, even with a professional calibration, is that rec2020 is not worth shooting for.

Maybe buy the second projector and try it out and sell one of them?

Hopefully some other folks will chime in.

Early in this thread I believe some folks shared impressions and measured results....or maybe that was in the RS400 thread?

The filter has nothing to do with lamp power. It is engaged automatically when a colour profile requires it is selected.

Does the JVC x9000 have a debanding filter? I was watching the Meg in 3D last night and the underwater scenes had lots of banding. That's in the original Blu-ray and on a HTPC I get rid of it with MadVR's debanding. But I was using a Popcorn Hour VTEN for playback so hoping that the PJ has a built in banding filter in one of the noise controls. Anyone know which?

It depends on the projector model.

As I mentioned previously, the BT.2020 profile on the x570 doesn’t use the filter as the projector doesn’t have one. On the x770 and x790 the BT.2020 profile uses the filter; the x790 also has the HDR profile which does not use the filter.

Thank you Dominic. And what about RS500 and 520? Do they automatically use the filter with BT2020 profile? Is it possible to enable the filter once automatically switched on? And how much of the light output will be absorbed by the filter once active? Thank you for your help

The RS520 is the same as the x770.

As mentioned previously, the filter is engaged automatically when the profile requires it.

Question from a newbie:

I have an rs600 paired with a denon 6500 and a panny ub820. I’d like to start watching some of our 4K movies. Do I need to set the projector on certain settings or can I just pop in the 4K disc and let the ub820 do everything for me? Thanks for the help!

If you have not loaded any custom curves for the RS600, the easiest setup would be to have the UB820 output SDR/BT2020, with the RS600 matching it (Gamma 2.4, Colour Profile BT2020).

Already replied multiple times. Some profiles require the filter, some don’t. You can “force” the filter On/Off manually using RS232 or IP control, but the profile will no longer be correct when you do that.

I also finally figured out how to use my AEMC CA813 light meter and took measurements of my lamp at 4000 hours (RS400, 108" 1.78:1 measured, 136" 2.35:1 screen):

I may even follow your example and take a reading of my lamp...

Anyway, I think that I'm caught up now. Mainly I wanted to know the significance of the "Lamp Replacement" message, and whether the projector might be giving that warning because of some underlying condition about the state of the lamp that it was sensing. But you have confirmed that, no, it is strictly a warning based on the Hours on the Lamp.

Thanks a lot!

- s.west

p.s. While doing some of my searching I came across a number of very helpful guides that you have posted in the last couple of years. I have bookmarked them. Thanks also for those!
Greetings again Dreamliner,

FYI, it is now late May, 2020 and we last communicated about the RS600 lamp back in September of 2019. I finally decided to quit my risky behavior and replace my out-of-ours lamp. I'd only gotten it up to about 3900 hours, but since I have one of Dominic's replacement bulbs, I figured it was time to dispense with the risk.

Anyway, using the pictures that you, and Dom, had provided at various times, I managed to do a successful replacement. I reset the hours and all is well. And, yes, I see now that even after 3900 hours the lamp had not dimmed significantly. I didn't take actual measurements, which I really should have, but just eyeballing it I can see that, while it is brighter, it is not remarkably so.

Bottom line: All is well, and hopefully I will get another five, quality, years from this projector.

I think I will, almost certainly, order a new replacement bulb, so that I have a spare on hand at all times. I looked at Dom's thread where he has those bulbs, and I think that they are currently available. So, that's my next stop.

Hope all is well with you and that you have weathered the covid-19 storm, as it were.

Cheers,

- s.west

Back when Manni used an RS500 he created REC2020 color profiles; a filter version and a no-filter version. This was before JVC released an official BT.2020 color profile.

To load Manni's no-filter version go to this page, and scroll down to the REC2020 heading for the zip file link.

https://www.avsforum.com/forum/24-di...500-rs600.html

3) Rec2020: these profiles were created using standard rec-2020 coordinates, as rec2020, unlike DCI-P3, isn't an option in the software. [EDIT: there is now an official BT2020 profile from JVC, see link to HDR settings and f/w update at the top of the post. It should be identical to mine but I haven't checked yet.] [EDIT2: confirmed, they are identical]
Same, pick up the version you want to use depending on whether your model has a filter or not. You can also select a version without the filter to use in a model with the filter if you want to try to reach as far as possible without losing too much brightness.
REC-2020F (with filter):
REC-2020NF (no filter):
I haven't done extensive tests with this one but it seems to be working fine.
Like the rec-709 profiles, this profile tracks better if you autocal it after importing it.


As Manni mentioned you might want to calibrate with Autocal after importing the no-filter color profile. I found that blues tended towards purple in my RS500 without recalibration.

FYI, it is now late May, 2020 and we last communicated about the RS600 lamp back in September of 2019. I finally decided to quit my risky behavior and replace my out-of-ours lamp. I'd only gotten it up to about 3900 hours, but since I have one of Dominic's replacement bulbs, I figured it was time to dispense with the risk.

Anyway, using the pictures that you, and Dom, had provided at various times, I managed to do a successful replacement. I reset the hours and all is well. And, yes, I see now that even after 3900 hours the lamp had not dimmed significantly. I didn't take actual measurements, which I really should have, but just eyeballing it I can see that, while it is brighter, it is not remarkably so.

Bottom line: All is well, and hopefully I will get another five, quality, years from this projector.

I think I will, almost certainly, order a new replacement bulb, so that I have a spare on hand at all times. I looked at Dom's thread where he has those bulbs, and I think that they are currently available. So, that's my next stop.

Hope all is well with you and that you have weathered the covid-19 storm, as it were.
Dominic's bulbs were the brightest of the generics I tried. I ultimately decided to go back to the genuine lamps as the were the brightest and most stable. I lucked out and got one with only 2000 hours on it (from someone on this forum who's projector died) and have been running that since January. I have two genuine lamps sealed in a box but cannot get myself to open them, I just might end up with an N7 before I ever need to...

I need to sit down one of these days and figure out the best way to calibrate this projector. I wrote a guide about it but when I did it recently the before/after pic I took of a test image were 100% identical, even though the calibration showed the drooping blue line...

I think I am missing an essential detail. I am sorry for being very naive but don’t 500/600 include in their default/factory settings BT2020 color profile? Or you have to upload them ? Just know. I was thinking about switching from a 420 to a previous 500 but that could impact my decision. Thank you

The earlier models didn’t have it and the user had to load it (Manni’s or JVC’s). The newer models came with it pre-loaded. They are identical, as claw said.
