That's great to hear. Are you using an RS500 as well? Chad's coming in today to do a calibration for me. I've got a 100" diag Stewart ST130 as well. I've always struggled to get proper light output even taking the iris to 0 from it's usual -9 when trying to display for UHD titles via CMS1 which I've attempted to set up for HDR (encapsulated in SDR).

Ya, I doubt you will get better results going with other curves when Chad was there.

Mine is a RS600 and was calibrated in June 2017. I'm not sure what the differences are between the 500 and 600 but I'm guessing they are negligible?

Just my opinion.....

I like to wait until the second version of a new class comes out. I sat out the rs400/500/600 round and let everyone here pound on JVC for the Gamma D and latency issues. The next round, I jumped on the rs620, which tightened up those items and had fewer overall issues to deal with.

Likewise, you'll see a dog pile soon on JVC for the issues with this next step up to native 4K. When the second round of these come out, that'll be my time to seriously consider an upgrade. Or, if JVC deals with the initial issues with a firmware update (which may require mailing the unit in), then I may consider in a few months when I can get a unit delivered already "fixed".

There are already delivered reports of pixel alignment issues with some of the new projectors. Let that get sorted out.

What we have right now is throwing a great picture. So good that the difference wouldn't be that noticeable in the immersion of a movie anyway.

Upgrade-itis is a real thing, and I have to fight it every time.

Yep, what we have is still great.

I must resist the upgrade disease too!

I think second generation is a good call too actually.

Looking at your gear, I highly, highly, highly recommend you get the Panasonic ub820 (or 9000) in your mix. It's a tremendous match with these JVC projectors.

You'll be able to tone map with the SDR2020 setting and probably eliminate the need for that HDFury device. One less path for the signal to go through.

Yes I must do that.

Main reason I have the Vertex is for auto switching between the uploaded curves. And for the Apple TV.

I just took my Vertex out; I don't have other displays in my theater room besides the pj. I still liked the idea of the macros for JVC projectors for source/profile switching, but there were options missing for broadcast 720p and 1080i that didn't play nice with my blu ray commands. So I ditched it and just change the profiles manually now.

The 820 can disable the HDR metadata now, as well as assign the tone mapping per the disc I'm watching.

I only have the PJ in my theatre also. But I was letting all the curve switching happen for the Panny UHD, Apple TV box and HTPC as well as my satellite run through the Vertex.

Like you say, it isn't foolproof though.

Gray scale drift after 1000 hours on my current bulb.

Peak output is down to about 16fl in low lamp nose, iris fully open — which is what I use for sdr — and to about 75 nits peak in high lamp mode, again iris fully open, which is what I use for hdr. That’s about a ten percent loss versus when the lamp was new.

These are calibrated outputs measured off a Seymour EN4k screen that is 8’ wide, not diag.

My screen is 90” wide, and my bulb is at 780 hrs.

What’s your throw distance?

We've had ours just over 3 years, watch almost nightly unless we're out of town and haven't been bothered by bulb dimming. Though I haven't measured for a while, it's still BRIGHT! I'm surprised we have only about 1600 hours on it. I thought it would have to be way more.

I just changed the bulb two weeks ago on my RS600. I had like 1,985 hrs. The image looked good, but I figured for the inexpensive price of just the bulb it would be worth the cost. I was 100% correct. I can see a difference big time and have no regrets.

Was it night and day, no. Is it brighter yes. How much hard to tell just by eyesight, but yes there is an obvious difference to me. I'm very pleased.

We're in about the same boat. I have an rs620, just crossed 2000 hours on the bulb, 11 feet viewing to a Stewart screen in a dedicated light-controlled room.

I ordered a new bulb because I found a good price on ebay on an OEM bulb (told about it here on AVS). Not really sure why because I still have a great picture right now. I guess too many years at this stuff tells me I'm SUPPOSED to need a new bulb right now. LOL, JVC goes out and builds a longer-lasting bulb, and I'm too stubborn to believe them, I guess.

I'm sure my bulb has dimmed, but it's been very gradual and hard to notice. I guess I'll still have a good bulb I can put back in the new bulb's box as a backup.

Did you clean your prism when you changed your bulb? That used to really help my RS1 back in the day. I may try that first and see if it makes a difference.

1600 hours in 3 years?

Now I feel like I need some sort of therapy.

Yeah... crazy... I kind of doubt the accuracy of the counter. As I say... most evenings have the question from my wife, "Wanna watch anything?" followed by my "Yes".

I think I hit about 1000 hours a year, max. Typically, I change a bulb before 2k hours. The math doesn't quite work since the 500 shipped four years ago and swapped the first bulb at under 2k hours and am just now hitting 1k on bulb number two. IIRC.

Glad I did that, however, because that means I am still able to hit reference output for SDR while in low lamp mode, which is very nice.

Which is a long way of saying "It depends." My screen gain is c .8 so I hit the "replace" threshold lots sooner than someone with a 1.3 gain screen of the same size (8 feet WIDE, not diag). Heck, I bet changing screens would get me another 1000 hours out of a bulb. But I love my AT woven screen. And that means lower gain.

Sounds like we have a similar screen. I have an SMX AT... 10' wide 16:9. When a bright scene comes it makes me wince, flashlights in your eyes are unpleasant and my wife sometimes asks me to turn the brightness down.

I stand corrected. I preordered in Nov 2015 and received it in January 2016.

What are the advantages in moving to the 40 series from a RS600? If I own a Panny 820 and use SDR2020 to view 4K UHDs are there any features that really stand out to make the upgrade a good move?
I’m going to guess that the HDR mode on the 40 series helps with streaming 4k and the low lag makes gaming much better but any other differences?
What about differences in motion(Panning), CMD, MPC, e-shift....?
The reason I’m asking is I was thinking of picking up a 540 if there have been enough improvements added in the 2 generations that have passed to make it worthwhile. Probably going to sit the first round of the 4k series out until everything is sorted out and grab a mid level 4k from the second generation. So either sit tight with the 600, or grab a 540 for now and see what the 2nd generation 4k brings out.

Someone will have a definitive list but assuming ALL your HDR content is played by the Panasonic and converted to SDR2020, and you are not a gamer, you may not find the improvements to be substantial. In fact, sample to sample variation may mean it gets slightly worse.

If you want to extend the usable life of your current projector, two things are worth considering:

1) a new lamp
2) an expert HDR calibration (eg, what Chad, dnice, etc do)

This won't get you low latency for gaming. This won't get you a workable iris. This won't get you automatic mode switching. (The last two items can be solved using a Vertex.)

In short, if you can upgrade for under 1k, you'll get nice convenience features. But for around half that, you can soup up your current system.

I thought the iris worked on the JVC's using an 820 and SDR.2020 conversion?

Agreed. I've an RS500 and Chad came by last Monday, and even with a lamp that's halfway through it's scheduled life, did his magic -- and it made a world of difference. He uncovered a big problem with my gamma (and as I figured, based on Manni's statements in the past re: the consistency of the Spider, which was likely the culprit), as well as the actual light output of the projector at this stage. Still I've enough light to view SDR and even HDR on my ST 130 100" diag. screen from 12 feet without going up to the higher lamp power setting. He did a great job pulling in dark detail without adversely affecting the detail in bright images. Worth every penny!

What was the specific issue with the gamma? Was it more than the infamous “gamma droop”? The Spyder is usually fine for gamma calibration, it’s the colour accuracy that’s hit-and-miss.

After years of obsessively upgrading my projectors every 2 years, my RS600 is the longest I've kept a projector. And I'm still extremely satisfied and see no reason to upgrade, especially as I was always upgrading for increased contrast and JVC has been going backwards on that. The RS600 finally hit that sweet point when it significantly upgraded the brightness while putting out the best contrast ever. So I'm still sitting out upgrades to the 4K models...I still haven't even started playing UHD on my RS600!

The gamma I'd calibrated before Chad arrived he discovered was far higher than target. Unless it changes quite a bit over time, I've got to blame the Spyder.
