I never got more than ~2000 hrs on my RS600. And then had to re-calibrate each time; a pita!

I know it seems like a criticism and sounds bad to those who already have the RS4500 - it’s not, it’s just a matter of feeling like you’re buying into the tail end of a generation rather than the front end. I’d rather buy on the front end, but hey, if they end up releasing a $60k 5000 lumen monster it may still well be that the RS4500 has the right value and feature for the money.
This is exactly the reason I have my rs4500 on order. I generally have your mind set and avoid buying electronics if the current generation over half the way to an expected refresh. However I think high end projectors are a different category. The key here is the major street price drops, and the fact that 4K HDR seems to have reached a very high level of fidelity and new models are only incrementally improved. As you say, a 5000 lumen DTM rs4500 v2 , back up to $40k etc price range, just isn’t worth it for me.

How long has your RS4500 been on order? It feels like it's been over a month

Each of these needs to be calibrated. So if you're at say -6 and Chad did *not* calibrate 0-3 then you'd lose some calibration moving to 0. But if he did all the steps (and he probably did) then you can just change from mid laser -6 to low laser 0 and be good to go. I made a lumen chart. So if you tell me what your mid laser iris setting is at now, I can look up the low laser equivalent.

1. I am interested in this “lumen Chart” you speak of !
2. I was not aware you need separate calibration points for different manual iris settings. What component of calibration changes with different iris ? Gamma ? Color?

Yeah it’s probably been a month. My integrator/ dealer said early April. We were supposed to take possession of our new house mid April but everything is pushed back probably 5 weeks because they are only letting in one trade at a time to minimize infection (we are not on full shelter in place mode but it’s probably coming). To top it off the theater will probably be done after we move in, because of shipping delay for some components like speakers.

And ATi scrapped the prepro we spec, so no idea what 16 channel unit to use instead! Ugh !l
But this is OT

These are 16x9 lumens in a calibrated preset. You an see low iris 0 is around the same output as mid iris -8.

I get why someone might be hesitant to buy a 3 or 4 year old technology when (they hope) a newer/better/faster one is just around the corner. But that's not me (in most cases) - and I why I have bought 1 year old demo cars for as long as I remember. I still get a 6 year warranty, and all but the very latest of whiz-bang goodies that the newest cars might have.

I would have never paid $35,000 for the RS4500. By waiting a bit, I paid WAY less than that (on the same order as what I paid for my last CRT projector!) and even as of today, I'd have to spend WAY MORE than I did for the 3 piece combo (Lumagen, 4500, lens) to beat the image I get now. And if I were faced with making a projector decision today, I would still buy the RS4500/Lumagen/Panamorph.

This is all true, and truth be told I’m not quite finished with my theater so it’s more like “let’s see what’s out when I get to the end”, which will also help avoid distractions in finishing

If there is no new projector I might go ahead, or if they release a Sony 5000 style that is twice the price I will probably choose the value option. Part of me wonders though if they may just do a minor refresh, a “v2”, update the electronics on the existing model and call it good. Either way I think I have time to see how it plays out.

In my experience that's the most likely scenario. Not only for the RS4500 but just about every projector from every manufacturer.

Morning Mark,

Okay just went and checked the settings Chad B. did.
And yes he went through all the set-up I'm positive that you speak of above.

See below images I just took ............
Am I correct in what I'm thinking or some other Settings ???









I want to give this a try and see if it's still BRIGHT enough compared to the now Settings for Medium-Laser.

Thanks for the assist buddy,
Terry

Terry. The big problem I see here is you have dynamic ctrl set to off. The rs4500 does not look good this way the big plus of the rs4500 is its fantastic laser dimming. The laser dimming improves the dynamic contrast by at least a factor of 10 and it's implemented so well it’s usually invisible.

You have it outright disabled. I run mode 2, but at the very least go set that from off to mode 1. That not only massively increases the life of your laser, but it also significantly improves your black performance. You should go through it on all your presets and enable that. It’s very disappointing to see a professional calibration that resulted in setting that to off. I don’t think there’s any scenario where off looks the best.

Mid at -5 is brighter than low laser at 0 So you won’t get equal brightness making that change. But you have nothing to lose by enabling dynamic control on all presets. Try mode 1 first. Like I said I like the more aggressive mode 2. You don’t get fade to blacks or anything with it off. And all dark scenes are a bright grey using only the native contrast of your panel which is probably like 20000:1 in your current configuration. Sucky. Also the dynamic laser dimming will lower the power of your laser on darker scenes, which is often. That massively increases the life of the laser and reduces fan noise.

Try auto 1 and go watch some sci-fi and be awed by the difference. You could also test auto 2 and compare. But auto 1 will be a huge difference from what you have now. Auto 2 can be a little overly aggressive at times but you get the pure 100% fade to black.

It took me a while to come back down to reality after the Christie showing, it really was an excellent demo. But I'm back to feeling pretty darned good about my Chadb calibrated 540.

In the calibration reports where I list the settings, I listed that as "optional" because it's a matter of personal taste, not "off". The calibration has to be done with it off, but then I normally turn it back on afterwords unless the customer tells me they don't like it for some reason.

That makes a lot more sense. In this case we know this customer didn’t turn it off since he is leery about making any changes. The rs4500 is not like other machines with dynamic iris that can show pumping effects. On mode 1 you really can’t see any artifacts and in mode 2 a few but not very often. I think the choice on an rs4500 is always do you want it on mode 1 or mode 2. Never off.

Terry.....Mark is spot on... The Dynamic Dimming of the Z1/RS4500 is one of its standout features... having it disabled is really hurting the image..

That then begs the question; What in all reality could they add that would have a marked positive affect on the image quality? I mean really, what?

The only thing I can think of that would even countenance the thought of a further outlay (although it should be free) is a DTM feature.
If it *is* DTM that they sell next, then many of you guys are already using Lumagen or MadVR, in which case it is a moot addition and they will get no more money from you.
It is the only feature I can see that would have a benefit for the older units and that is a feature they could more than likely leverage into software using current hardware, if they really wanted to.

Basically I am struggling to think what they could possibly bring to the table that would make anyone (who doesn't have heaps and heaps of cash lying around) want to upgrade at this stage.
This is a perfect opportunity for all manufacturers to stand behind their customer base (who have already spent disproportionate amounts on what is in essence 'a TV set'), and build up some goodwill.
They will need it.

It will pay off bigger down the road than the cost of charging for something now I say, especially as incomes are likely to dip for years as everyone pays off the debt of keeping things moving through this crisis.

It would refresh the 4500 enough that it would be viable and modern for new purchasers for another four or five years, but not a “you have to go upgrade” like a brand new model with an entirely new laser engine or panel might be. I’m not personally saying this is the most likely scenario

I’m struggling to think of a situation where I’d consider a company simply not refreshing their product for half a decade being considered customer good will. They can’t simply release one product, ever, and never innovate for fear of upsetting the existing customer base. If they don’t release something this September, the 4500 design will be five years old come next opportunity. At this point I think new purchasers are aware the segment might be due for a refresh, they’re buying anyway and won’t be too disappointed if there is one.

Upgrading the electronics might mean just adding a processor that can handle DTM and have overhead for future upgrades, possibly HDMI 2.1. This brings more than just higher bandwidth - there are is high speed source switching, A/V auto sync, various latency improving features, makes dynamic HDR required, and a few other things. Of course this means everything else needs to be HDMI 2.1 as well, so this is again about being a viable part of the next generation of AV equipment, within the next year or so everyone is going to be releasing their 2.1 stuff and people will want to make it all match.

2 things I think would be appealing:

1) Significantly higher native contrast. It would have to be a lot more than what the native panels on the NX series offer to really get one of us to sell off our RS4500 and upgrade.

2) Significantly higher lumens. If the RS4500 is 3000 lumens, they'd need something in the 5000 lumen range I think. 3500 lumens wont cut it. 4000 is getting closer. The higher lumens would allow for us with smaller screens to crank our manual iris down further for a massive increase in native contrast.

2) Significantly higher lumens. If the RS4500 is 3000 lumens, they'd need something in the 5000 lumen range I think. 3500 lumens wont cut it. 4000 is getting closer. The higher lumens would allow for us with smaller screens to crank our manual iris down further for a massive increase in native contrast.
I agree, those would be appealing.

Contrast increases are always to be welcomed of course. However to get users away from these great devices that already throw superb images, the difference would, as you say, have to be massive. Especially for you guys with DTM devices.

More lumens is always good but it also has its downsides.

I was more saying that the things that they usually tout to get TV owners to upgrade (more brightness and 8K etc) just aren't that marketable in the projector arena at present. (Especially as good DTM is now giving superb imagery to even modestly bright devices).
I shudder to think what they would charge for a native 8K projector that had the same blacks and general performance as some of the of the current, very accomplished units.

I dont consider 8K a worthwhile reason to upgrade. After having to move my whole theater around to get to about 7 feet from my screen to benefit from 4K, I can tell you that 8K is just too small to notice the difference unless you're around 1/2 screen width away. No one sits that close.

What could they realistically add that would make the new model significantly appealing than the current model, really?
There are things that would be compelling, but they all hinge on current satisfaction levels rather than a hankering for new standards and tech.

At this point I think new purchasers are aware the segment might be due for a refresh, they’re buying anyway and won’t be too disappointed if there is one.
They can sell any product for as long as they want without refresh if (as happens on here) it is still being hailed as basically the best on offer (for less than the price of the moon that is).
The price will creep down as it ages but until it gets to the stage that REAL tangible new tech is here that is a compelling reason to upgrade, it can simply keep on selling as is.

Of course this means everything else needs to be HDMI 2.1 as well, so this is again about being a viable part of the next generation of AV equipment, within the next year or so everyone is going to be releasing their 2.1 stuff and people will want to make it all match.
That is all true of course, but What is the actual need for HDMI 2.1 on PJs when HDMI 2.0 is giving such great results on what we have already? Games is the top of the list of course for high frame rates and there will always be those that simply *must* have the latest thing regardless of the cost or what improvement it truly brings, but I would say that the ones who will shell out for something that would doubtless cost more than the 4500 was at launch, will be few enough in number for it not to make enough sense to release any model like that until it appeals to a larger customer base.

Until these flagship units are truly surpassed by something costing a tiny fraction of their price, they can and should (in my view) continue to be sold for as many years as possible.

I think the days of bi- or even tri-annual (or more) releases has come to an end. The environment was the first reason why things now need to last longer, but now this pandemic will probably put some economies on the back burner for many, many years giving people a lot less money to spend than previously. I hope I am wrong on that front mind. Nobody likes paying more tax.

You have it outright disabled. I run mode 2, but at the very least go set that from off to mode 1. That not only massively increases the life of your laser, but it also significantly improves your black performance. You should go through it on all your presets and enable that. It’s very disappointing to see a professional calibration that resulted in setting that to off. I don’t think there’s any scenario where off looks the best.

Mid at -5 is brighter than low laser at 0 So you won’t get equal brightness making that change. But you have nothing to lose by enabling dynamic control on all presets. Try mode 1 first. Like I said I like the more aggressive mode 2. You don’t get fade to blacks or anything with it off. And all dark scenes are a bright grey using only the native contrast of your panel which is probably like 20000:1 in your current configuration. Sucky. Also the dynamic laser dimming will lower the power of your laser on darker scenes, which is often. That massively increases the life of the laser and reduces fan noise.

Try auto 1 and go watch some sci-fi and be awed by the difference. You could also test auto 2 and compare. But auto 1 will be a huge difference from what you have now.
Auto 2 can be a little overly aggressive at times but you get the pure 100% fade to black.
Mark,

I almost Forgot to mention your Right changing the settings I Posted in the pictures did nothing of a Positive-Nature.
I watched all different things with those settings Changed.
Then went back and put them back where they were and it was an (Immediate-Improvement) so like I said your right buddy.

You my AVS Long-Distance Internet (Friend) are a Life-Saver No-Doubt.
See further comments below on what you have said to me and YES I'll make the Necessary Change Today thanks to you catching this !!!
I Thank-You kind Sir ...........

Hey Chad B. once things settle back down and my guy, Charles, "Wolf Hill Technologies" does my Atmos install and the new 4 SVS PB-4000 Subs.
(See link in below Signature for those installs Chad)
I'll send you and your Dad an E-Mail to get on your List to do BOTH my Video as well as the Audio.
I look so Forward to you Returning once everything is Installed ...........

And if you by chance think I am even remotely a tiny bit concerned over the (dynamic ctrl set to off.) I 100% promise you I'm not in the least buddy.
I'm going to change it to Mode 2 as I really doubt I'm going to even be able to recognize any Negative-Video-Effects.
If I do by chance see Negative-Effects which in my case I Highly-Doubt then I'll switch it back to Mode 1.
I sit something like 12' or so from the 123" 16x9 screen so it's not like I'm right on top of it.

The rs4500 is not like other machines with dynamic iris that can show pumping effects. On mode 1 you really can’t see any artifacts and in mode 2 a few but not very often. I think the choice on an rs4500 is always do you want it on mode 1 or mode 2. Never off.
Your right buddy I don't Ever-Change-Any-Setting or Settings especially if Chad B. did the Custom Calibrating !!!

The types of artifacts you’d see in mode 2 is like on a few dark space scenes maybe the laser turns off for 1-3 seconds as it doesn’t have enough data on the screen for its algorithm. This may not ever happen to you depending on what you watch. You’d notice it from any distance. The trade off is you will get absolute fade to blacks on transitions and darker blacks on very dark scenes. I’m excited to hear your impressions on the change.

Mark,

I did Edit the post above with the below comments to you.

I almost Forgot to mention your Right changing the settings I Posted in the pictures did nothing of a Positive-Nature.
I watched all different things with those settings Changed.
The pictures on all content were a Gray look and Dull !!!
Then went back and put them back where they were and it was an (Immediate-Improvement) so like I said your right buddy.
They then were Super-Bright once again !!!

I'm going to chance it to Mode 2 as I really doubt I will see anything that will be all that much of an issue.
As you say if I do then simply chance it to Mode 1 ............

Hey Mark, seriously, I'm glad you caught what you did on the 1st picture I posted and saw the setting was Turned-Off.
Honestly I would have never-ever even recognized that much less thought to change it.

Your an OKAY fellow ..............
Terry

Actually, the RS4500 has only been shipping for just over 3 years. I got one of the first ones - Released January 2017 https://www.projectorcentral.com/JVC-DLA-RS4500.htm

The Sony VW5000 on the other hand has been shipping for 4 years come April ( Released April 2016 ) - https://www.projectorcentral.com/Sony-VPL-VW5000ES.htm

I know we've had this discussion before, but for Terry, I find the less aggressive Mode 1 to work better in my setup, as it never shows objectionable artifacts - except during the movie " Get Out " on 4K. For that film I just turn it off.

I could give you a list of scenes in movies where Mode 2 over-dims things. I don't like that.

I don't like that.
Craig,

Maybe since mine has always been Turned-Off I should actually try the Mode 1 1st as it seems it will be a Bigggg improvement over mine being Turned-Off.

I'm going to be really interested to see if there is an obvious improvement over the below images that were with mine Turned-Off all this time.








Guys, comments are welcome ???

Terry

I’m going off the Sept 2016 announcement. If they announce one in 2020 it may have a similar lag and may not ship until early 2021, that would be four years as it is. If they don’t, next window will be five years.
