Right now, the JVC looks to be applying a set 'curve' for each film you put in. We used to have 1 or 2 custom curves in total and pick the best one based on metadata, now the JVC will read metadata and update is own settings on a film by film basis. it can do this with probably millions of combinations since it uses 3 sliders to do it. But they are static, ONE curve per film is possible, thats it.

But what if the Metadata is wrong - I can tell you over 70% of the metadata IS wrong.

What if the title has a 1200 nit pixel for a millisecond and thus its metadata reflects that, but 99% of the film is around 600 nits peak? The JVC will be tone mapping to 1200 nits and the whole image will be darker than it ideally should be.

MadVR will know this and as it reads and measures the peak of every single frame, it can adapt extremely quickly within 1 frame even if you have it set that way, it can also detect scene changes, there is a whole host of algorithms which juggle and decide when to change the curve for a set event.

In fact one of the most recent things we are doing is having MadVR throw away the top 1% measured peaks, the image suddenly becomes exceptionally vibrant just by doing this. Thats one trick.

Lumagen I think is working on this too so should eventually be playing the same game if not already, but the MadVR development has been crazy in depth and rapid on this for months now, its extremely good. It is pretty much indistinguishable from full blown Dolby Vision now. But it will work for every title you put through it.


I have a extra PC laying around. My understanding is MadVR takes quite the graphics card to run though.

Picked up my NX7 today. Made my order maybe 3 weeks ago.

I picked it up directly from the distributor, so it didn't even get to the dealer. While I was there, I happened to see a form showing the dealer costs on these units. If I could get those prices, I may have been tempted to get the NX9.

Probably won't get it up and running for a day or two. I did get my shelf installed today, but still have a fabric panel to modify, and I am hoping that might happen soon. Just a little less worry putting that back up before the projector meets its home.

Would you consider that a win?
It’s a win if you can’t see any convergence problems from your seating in ny opinion.

Yeah sure, I guess. Accuracy is a strange word when talking about HDR though.

Madvr can also select a tone mapping (target nits) curve in the same way the JVC does on a case by case basis, this is different to its rolling dynamic tone mapping. At that point one could probably make the two look very similar. I know I was able to get madvr in the past look almost identical to curves.

There are still heaps of things going on with HDR and MadVR. Development has been in depth for 6-9 Months+ and dynamic is only in the past couple Months.

I'm sure the JVC does a pretty darn good job. I don't think you would need to use custom curves at all with it based on what I'm hearing. That's an achievement for sure. There are no other projectors out there right now doing anything similar.

SDR BT2020 is tone mapping. That's also what the Panasonic if and Oppo does. Along with Lumagen I believe.

When you use madvr tone mapping it actually needs your display to be in gamma 2.2 mode.

Of course! That’s what I’m doin now. From everyone I’ve talked to though they’ve indicated that’s not normal.

Gonna run a few more tests in the morning to see what’s what.

So if you use madvr tone mapping we need to use gamma 2.2 instead of 2.4?

If you are in low lamp and have not closed the iris down, you are running about 35FL for SDR. Your black floor is pretty high.

I’ll run through all that and get back to you.

You think that might be it? I have never adjusted the manual iris at all. Seems like from what I was reading most people left it alone.

You have to tell madvr which gamma you are using. But the tone mapping algorithms are based on a 2.2 working space so it's best to use that.

You could set it to 2.4 in the on the pj and madvr but it will probably not look different.

I thought that gamma 2.2 was only if you were using a 3d lut and not pixel shaders?

Thanks for your input. I meant that there was no further utilization of the auto tone mapping feature within the JVC since it occurs external to the PJ. What I'm trying to ascertain is whether contrast & black levels are appreciably improved with the MadVR tone mapping HDR10 versus SDR BT2020 tone mapped external to the PJ.

For SDR, pretty much everyone adjusts the manual iris to set the light output.

I’m getting it mixed up then. For HDR they set Auto and go. For SDR you’re right. Manual Iris is adjusted.

Let's agree that it's not normal. But if your unit is good otherwise, then who cares? Also, I bet more people have those types of things and just don't know because they're properly zoomed to their screen bezel

This is what I do, FYI. 2.4 in projector, 2.4 in madVR. I just never thought to try 2.2 on both. I'm happy with how it looks.

If madvr is as good as it is, then JVC should license it and incorporate it into their future projector models. Sounds like a match made in heaven.

Enter in screen size, screen material, screen gain, nits level, and madvr would dynamically optimise the HDR picture in real time.

I think most people turn on the projector and go. The dynamic iris handles contrast.

I can totally get down with this, but I’d argue that we’re all on this forum due “good otherwise” not being....good enough.

So my new projector (RS3000) landed today. I'm letting it acclimate from the 20 degree outside temp to my house temps. So I need to make a few decisions before hanging the PJ. I have a couple questions that I hope someone can help me on.

Here are my system measurements. 16:9 AT drop down screen with top of screen height 8.5 inches down from the ceiling. I can raise it another inch maybe or lower it 4 or 5 inches if desired. The throw distance will be about 14.5 feet. Now for the PJ side. My current mount is set such that the lens center will be 10.5 from the ceiling or I can change the 3" down tube to a 6" down tube. The later would give a 13.5 inch drop from the ceiling.

So what would be the best setup for vertical Len shift positions? From reading posts, some have mentioned halos or barrel reflections and being at 100% of V shift might not be advised. The next question is about horizontal lens shift. Here I can get very close to being centered. Or I can move the ceiling mount to take it off of center if desired.

So those are the first two decisions and questions I'd like to get some feedback on. What are your recommendations?

I would just start with whatever is most simple for you or makes best use of the space (projector not hanging down too low) and only adjust from there if there is a problem. My vertical lens shift is at the maximum on my RS2000 and the picture looks fantastic. The people in this thread who have seen internal reflections have indicated that the problem is worse toward 0% lens shift. Some have hypothesized that using a lot of lens shift may cause uneven focus or other issues but others (like myself) see no detectible detrimental effects.

I would also start horizontally centered. That gives you the most vertical shift range and if there are any slight asymmetries they will tend to be less noticeable vertically than horizontally.

I kind of feel like we're all here to learn about our projectors and enjoy them. It's hard to enjoy your projector if you're obsessed with things that aren't that important
I'd stick to caring about problems that matter or impact the actual performance in a noticeable way.

Enter in screen size, screen material, screen gain, nits level, and madvr would dynamically optimise the HDR picture in real time.
Except madVR only runs on Windows and through DirectX on a relatively powerful nVidia or AMD GPU. How would you put that in a projector? Even a console like a Playstation isn't allowed to use DirectX because it's completely controlled by Microsoft. Now if madVR was written to run on OpenGL then maybe we would have something.

Im doing exactly the same as welll, 2.4 gamma on the NX9 and 2.4 gamma in madvr, it looks beautiful on SDR and HDR. All the shadow detail is there right down to 17 and 234 which was harder to achieve on the X9900.

I don't think the issue is directx or licensing to microsoft. JVC would need a very power processor with capabilities similar to a GTX 1080ti I think. If JVC wanted to work with madshi and provided a proper hardware platform and dev kit, I'm sure he could make it happen. It wont.

To not use DirectX madshi would have to completely rewrite madVR and how do you know he knows as much about OpenGL for instance? He’s heavily utilizing The DirectX framework to handle the complex processing.

I mean anything is technically possible, but yeah it would be quite a different functioning system and a rework of all the code to remove DirectX from the equation.

Also, if it was just for doing tone mapping you don’t really need anything near a 1080Ti. My laptop's 65W GTX 1060 max-q has no problems with the latest builds and dynamic tone-mapping with all the trade quality for performance options unchecked. Though of course it would be nice to have some of the other features built into a display as well.

I'd stick to caring about problems that matter or impact the actual performance in a noticeable way.


Right, but then again what we think is important is subjective also. I’m still using the crap outta my projector. Just want to make sure I’m not missing anything. I’m anal about little details.
