There is no need to worry about DI artifacts.

Many (most?) users don't experience them with their sources/settings, or don't notice them, or don't mind if they occasionally spot them.

So do NOT look for them.

I don't believe these are due to unit to unit variation, so it's not something that would be improved with a new unit, unlike significant issues with convergence, focus or uniformity for example, but I could be wrong.

You should also know that you're unlikely to get a perfect unit, and any unit could improve on one aspect and be worse on another. So if you have a unit that gives you a good picture overall, without any obvious defect, keep it!

I enjoyed the DI on my RS500 for a long time before noticing these artifacts.

Once you see them, it's hard to unsee them (but you have the option to switch the DI off).

But if you don't notice them (or if you don't mind switching the DI of, which brings great stability to the picture without hurting contrast in most situation), it's very, very easy to enjoy a great PJ. That's what I do with my RS2000.

There are lots of recommended settings in the calibration thread (see my sig).

Have fun and enjoy your new toy!

I would wait until around 200 hours for the calibration just so your lamp has some time to break in. Maybe that is a few weeks for your usage.

First congrats on the new toy!

Let the projector warm up for a good 20-30 minutes before checking convergence and correcting it if necessary. To date most of us have seen good convergence and lens uniformity, so hopefully yours will be great here too.

I use the following:

SDR:
Color - 6500K
Gamma - 2.4 (some use 2.3 which I tried and went back to 2.4)
Wide AR - auto 1 / aperture -6
Narrow AR - auto 1 / aperture -9

HDR:
Color - BT2020
Brightness -3 (this can vary,decrease until you see crush)
Contrast +1
Gamma - HDR PQ - Mapping level 3 (this varies by screen, yours is smaller so probably 1)
Wide AR - auto 1 / aperture -3
Narrow AR - auto 1 / aperture -5

Use the Zoom option in the installation mode (lens memory) to use the full panel 17:9 for aspect ratios wider than 1.85:1 (so for me 2.00:1, 2.20:1 and 2.35:1). This is a 10% or more bump in light for scope films with no scaling artifacts seen. Use Native for aspect ratios 1.85:1 or narrower to avoid cropping material.

I use the iris to equalize brightness for wide and narrow AR material for both SDR and HDR. I know the rule of thumb is wide open for HDR, but I like to keep a little in reserve as the bulb ages and I like the brightness to be more or less consistent when watching different aspect ratios. I can open it up a step after a few hundred hours to get back to what I'm accustomed to.

I'd definitely use the DI and see if you have any issues with it. As I said earlier I've had some local AVS members here for movies and all of them know it's a potential issue, but no one spotted it.

It seems there also is a new MadVR picture mode in the new FW :

Only a rename of User3 for the show ?

It's a picture published on the french homecinema-fr.com forum.

No way can you say if someone can pay (for example) $22k for an RS4500 they're good for $50k for RS4600 its just not similar.
Well see what happens, the RS4600 or what ever they choose to label the new laser projector, may come out at an even more favorable price.

It will be interesting to see what comes after the RS4500. I'd have a hard time buying JVC is going to double the cost on it. Unless maybe they split up the model. An RS4500 successor with modest improvements at the current price point (new panels and DTM) and a bigger brother with something to justify that $60K rice tag. Maybe if they managed to somehow hit 6K calibrated lumens or something crazy like that they could justify that price tag. It would have a lot of appeal to the huge screen/room crowd that can likely afford it. But who knows?

I always assumed a rs4500 replacement with 5000+ lumens for like 50K and a NX9 replacement with a 3000 lumen laser for around 20k.

Most people think the NX are so big as to have room for a laser light source in the coming years.

Yeah the tear down shows provisions for it. That's more or less what I speculated, just with the modestly improved RS4500 being the new NX9. With the same lens I doubt anyone in the market would care if the RS4500 replacement was using the new chassis vs the current one. As long as it was an improvement.

Considering the price that the MadVR Envy just got announced at $5k and $10k for both models I’m even more looking forward to what JVC can doo with their onboard DTM firmware. Just wish they improved upscaling as well with that firmware.

Could anyone kindly point me in the direction of where to purchase a new NX-7 bulb (preferably online) and at what price?

Hubby is going to Miami FL for a conference later this year and hoping to get one for significantly less $ than they are here in Australia.

Sorry if this is not allowed in main thread, please PM me if not.

So the NX7 is made in China?

I would not be holding my breath for an RS4500 replacement. I don't believe there is anything in the works for such an animal. Nor would I be expecting a big brother.

It's a picture published on the french homecinema-fr.com forum.
The "MadVR" picture mode in that picture is most likely a renamed USER3. This is probably because they are using a DCI-P3 calibration (which madVR or the Radiance allow), when all consumer sources expect BT2020 when sending HDR or HDR tonemapped to SDR, which is what you have by default in the HDR10 picture mode. This probably allows them to select the proper baseline calibration depending on the source used (madVR on an HTPC or a consumer source).

If anyone knows different, hopefully they'll post here.

Two questions about your settings (thanks for sharing):
  1. At what AR do you switch to Wide AR aperture (= -6)? Starting from 2:1?
  2. Are brightness and contrast working with BT.2020 and HDR? I thought they weren't considered, at least that is what I read. I actually experimented a little with brightness and I saw no changes...

Exactly. Depending on what it streets for I may just look to pickup a used Lumagen down the track.

Ya, perhaps other folks are in the same boat... it would have been within reach at $2.5K-$3K, but the base model at $5K is a bridge too far. Especially after the expenditure for the NX7 itself (not cheap!).

That's doubly true with JVC coming out with per-frame dynamic tone mapping for free. JVC's algorithm might not be as good as MadVR's, but I'll try it first, and depending on its performance may stick with that, or perhaps go the HTPC route. (Now if JVC would improve the frame interpolation in a future update, that would be wonderful.)

That said, I wish MadVR the best and hope they sell a ton of Envys. It's great to see innovation in the HT industry.

I switch to Wide with 2.20:1 (haven't ran across 2.10:1 yet, but hear it's out there). Brightness and contrast both work. Brightness is pretty subtle. I had to pause on a scene with full black, get close to the screen to try to block light pollution from the menu elements and adjust down until I couldn't see a change. Not terribly scientific, but I'm getting a professional calibration in November so I'm not terribly worried. I don't see any black crush.

Oh I'm not. The question was just asked by someone cross shopping the NX9 and RS4500 what they should be worried about. That spiraled into when/if it would be replaced. A lowly peasant like me isn't likely to afford a $10k+ projector anytime soon. I'm lucky the Minister of Finance (wife) allowed the NX7

While we wait for dynamic tone mapping, I've been using the NX7's (fixed) auto tone mapping and getting very inconsistent results. Some 4k HDR content I watch looks great, others not so much. Most episodes of Amazon's Carnival Row, for example, look very flat with elevated black levels on my screen. However, a couple of episodes looked pretty good with better contrast. Is this down to the show having wonky metadata?

Netflix's The Spy is also problematic. Much of the show takes place in the bright Middle Eastern sun, and whites are often severely clipped and blown out. Episode 3 is particularly bad in this regard. At first, I wondered if this was an intentional stylistic choice to evoke the scorching sun, but when I switched to 1080p/SDR, that looks very different. The scene still feels "bright," but there's much more detail and less crushing in whites.

My current settings are:
SDR: Low lamp, Iris at -12
HDR: High lamp, Iris at -5

Anyone else experiencing this?

The Spy is 2.10:1 for some reason.

My first thought would be to go in under HDR(PQ) and adjust either the overall mapping level or the tone controls. For the overblown whites you're probably going to be reducing the mapping level or the bright level. Dark level should help with the black floor. You're most likely correct in guessing that the metadata is the culprit here.

bring on DTM...Static metadata sucks...its built for the worst case scene which may be 5 sec in length and the whole movie gets compromised...MI Fall Out look crappy on my N7 compared to my Sony 900F, altho something like Mortal Engines looked awesome on the N7...hit and miss...

Agreed. DTM is a game changer.
