Can anyone confirm the command to load a lens memory on these would be:

x21/x89/x01/x49/x4e/x4d/x4c/x(30-39)/x0A


Looking to get my iRule setup, and reading the control documentation, and thinking that's what it comes out to for those. Or am I reading it wrong?

The codes I downloaded from iRule have a single Lens Memory command, and it looks like it's a remote control command, so I'm assuming that is just to bring up the lens memory menu and not to load any directly.

My ~1 minute above is on an RS2000. 1.20 firmware. I wonder why there is so much variability.

I have the same firmware. Not sure, everthing works well otherwise. It does concern me a little bit though. I've only powered it up 3 times and didn't even notice the first two times I powered it up because I was doing other things but, with the 3rd power up I timed it with the stop watch on my phone. I'll check again tomorrow night.

Wow! So I guess if one is going to watch a movie on the NX7, you turn it on and THEN go use the bathroom.

Sure hope the next update makes the start up time more reasonable.

You turn it on, eat dinner, and then start watching.

The purists would warm up their projector for 45 minutes so that they can enjoy the movie in the projector’s calibrated state.

I’m not kidding. There are those who do that.

There's probably a big overlap between that group and those MadVR kooks.

I have never timed it, but the 540U we have takes 1-2 minutes for sure. Just enough time to get settled in I guess.

I’m not even sure how long it takes my X790 to start up. I usually grab the remote, turn everything on, walk away and come back in a few minutes when everything is ready to go.
To me that´s definitely an issue. A couple of minutes ( I interpret that as 3+ minutes) is nowhere near acceptable. Imagine you get home late, the final is on and you sit there and pray for your projector to start up...

Sounds like a very bad thing to me.

You are missing my point, which is probably my fault as I am not explaining it right or something.

The way you are saying things, it makes it sound like you felt your rs4500 was a piece of junk without MadVR. Bottom of the barrel and if you had to rate it on a scale of 1-100, you would give it a 50, meaning it could be easily twice as good overall. Boy, you had a really crappy projector before MadVR made those changes a few weeks ago and made it twice as good, bringing it up to a near 100 out of 100. Night and Day, Twice as good, easily, right?

But we both know that is a load of hooey. Your rs4500 is easily considered one of the best projectors you can buy for under $100k. So adding MadVR doesn't make it twice as good, it makes it incrementally better as a whole. We have top notch theaters, and while one particular aspect might gain significant improvement with an upgrade, the overall performance of the theater doesn't suddenly skyrocket. If one small aspect change suddenly makes it "night and day" better, then it sucked ass before.

So if you already feel like your HDR performance with a custom curve or tone mapping is excellent, 95% of perfect, and almost as good as it can get, improving it doesn't suddenly make it twice as good. It makes it incrementally better. And even if your HDR was crap before and suddenly it is better by an order of magnitude, your top end projector didn't suddenly get better, only one small aspect of it did. That is also an incremental change.

All that being said, I do understand what MadVR is doing, and I am not trying to take away how much better it is than regular static data based tone mapping. I won't even argue that the producer or director or cinematographer may have wanted it to all be based off a certain set of parameters, leaving dark scenes dark and some bright scenes overly bright and blown out, because it is all semantics. The fact is, between the way you view content and the way your theater is set up, adding MadVR with an HTPC *added* and didn't *subtract* from your theater. That's awesome!. In my setup I would be sacrificing one of the major properties of my theater, something I have spent a lot of money and time to make work nearly perfectly, and for an incremental improvement in the overall quality of my theater, it isn't worth it, especially when you consider that it would only affect 3% of my total viewing experience. The JVC built in tone mapping is an incremental improvement for me over my current custom curve, one I could make without sacrificing my simplistic setup. The DCR lens will be an incremental change in viewing scope, one that in some respects will simplify the operation of my theater even further (more because of the JVC memories than anything else). I am getting two very nice incremental improvements to my theater (which I already feel is worth the money), and the last thing I am going to do is think it is all suddenly crap that can be twice as good with MadVR.

Now, if the internal tone mapping of the JVC ends up being a step down from what I had with the Epson using the custom curve, then I will have to rethink some things, starting with why I made such a bad decision buying the JVC. I hope it doesn't come to that.

Strange thing happened last night. I had the projector running for about 4 hours. Watched a movie and then played some Xbox One X. While I was playing, the screen went black, I looked back at the projector and all the lights were flashing. I gave it a minute, and clicked the power button again. The projector turned back on but I'm not sure what caused it to shutdown that way.

You'll be happy with the JVC auto tone mapping. When given the right metadata it works great and any other processing including MadVR is just for taste and probably is changing the filmmakers original intent.

When the metadata is incorrect then it might take some adjusting but honestly it is pretty easy to dial in a good presentation with a little tweaking.

All of it boils down to personal taste in the end.

You reached the 3 hour time limit of the JVC.

I find this interesting, since the NX7/rs2000 was used by Lygren to demo a 13' wide v6 dreamscreen at the last couple shows. That is a ~.83 gain screen, roughly the same width as mine (I'm at 150"), not a ~1.2 gain Stewart (basically the same gain I am using). He said the image was fantastic, specifically on Blade Runner 2049. This example is one I used to feel better about my purchase... https://www.avsforum.com/forum/24-di...l#post57412026 Previous to this he used the Sony 5000 light cannon, and he prefered the far cheaper JVC with far less light just because of the tone mapping that is built in (and the better contrast).

But hey, it's all subjective. Some people are totally satisfied with the tone mapping in the JVC, some aren't. I will reserve my judgement for the cold day in Hell when my rs2000 finally arrives, lol. As long as it is better than what I have now, I will be satisfied with my upgrade.

Maybe there are some markets where they aren't the best, and another theater ups the ante, but I cannot believe for an instant that they would ever be anything close to "the worst experience ever."
One of the best theaters is the Silver Spot in Naples FL
They use very dark exit signs, no spillage and great pic.

Thats not right Mike, the iris is working different when you use the JVC tone mapping, it doesnt fade to black, others have mentioned this also. When you play SDR the iris closes all the way down, JVC need to fix this for HDR, but doesnt worry me as I dont use its tone mapping.

Im sure you will be more than happy with the tone mapping on your new NX2000 when it arrives. I was also very happy with it on my NX9 as it was the first time I had used my HDR titles with a good result. However since I had been using madvr for many many years and having over 1500 BDs on my Nas, I thought I should try the new dynamic tone mapping on madvr since it had just become public round two weeks ago, thats when I noticed the "night & day" between the two. I stumbled across it by shear accident, but thrilled I did.

Its different for you, you have never used madvr so you dont have any comparison how it upscales to 4K or tone maps dynamically, when you cant compare one is always happy with the results they currently get.

I was like that many years ago, hearing how good madvr was all the time,...... it was very frustrating just wondering how something could be better than the great results I already had, but in the end I feel down the rabbit hole and got hooked

I once had a Lumagen Pro, I dont use it in my system now. But then my system is simple, just madvr with 1500 BDs on a Nas, dont stream or do anything else

I would not get hung up on it. By mid March, I suspect it will be different.

Sounds like it over heated. Is your projector mounted so that it has sufficient clearance and room for the exhaust vents? Are you at a location that is above 3000' in elevation? If so then you need to be running your fan in high altitude mode.

I asked my dealer his thoughts on these models getting replaced so soon and his comment was:

"No, haven’t heard anything. And I would literally bet real money that there will not be any new models coming at CEDIA."

As for problems, he's delivered all three models and had zero complaints so far.

On long boot times "Projectors always take quite a while to boot up, and 4K HDMI handshake issues prolong it further" So possibly the variances in boot times could be due to handshaking? That's just me speculating. It shouldn't vary by much though I wouldn't think.

He also hasn't been informed what the cause of the initial delay was but thinks the CPU overheating claim is "pure internet conjecture". He was going to ask JVC if there's any validity to the claim, however. Probably after I get my RS-2000, it'll be confirmed and new replacement models announced.

Given the cost of these projectors, particularly the NX7 and NX9, and given that some projectors received by Arrow have not been within spec, does it make sense to purchase a light meter to check that your new projector is giving you something close to the specified lumens? If so, what light meter that is economical would you guys recommend? And is it correct that the meters that are compatible with the AutoCal software (e.g., the Syder 5) would not be suitable for this purpose?

As an absolute measurement device the Spyder isn't very good. It only works well for gamma because all the measurements end up being self-relative to its own measured peak white.

I think for absolute light measurement you'd want a light meter or a much better colorimeter / spectro.

So would something like this be sufficient just for measuring projector lumens?
