I have an x7900 and a tw9300. The latter should be the EU equivalent of a 5040ub.
In my opinion Epson is brighter and has a very good intra image contrast.
JVC is better in terms of definition (DILA vs LCD) and black floor.
It really depends on the environment. JVC is a good choice if you have a totally light controlled room, a batcave while Epson is perfect for a living room.

Edit: I also have The Lego Movie 2 3D as well as How to Train Your Dragon 3 3D pre-ordered. I like to plan way ahead lol.
On the TV side of things you are right. They bring 3D to market and say look at this, look at this. Then one day they just take it away......

So happy that projector companies are still including it. I hope they do for as long as possible.

I did that very upgrade. My conclusion was that the Epson 10.2gbps limited bandwidth was the killer and I'd have otherwise kept it.

I was happy with the Epson when I had my projector in a living room, but I recently bought a house and now have a dedicated room. In my experience the JVC is the better projector as there's much more perfection to squeeze out of and appreciate it. The gamma adjustments, black levels + 18gbps all make it what I'd consider the best quality projector for the price.

Im really, really, REALLY hoping that they do a 3D release of Alita:Battle Angel. My local theater didn't show it in 3D so I missed out there. I seen on Film-Tech they would not send a 3D DCP to theaters unless they could prove they where hitting enough light with their 3D systems. Weird they had them take it with an iphone but more info is below.

Me to!, I’m looking every day to try and pre order Alita battle angel, preferably the 4K 3D combo I’m sure it will eat a release. I wanted to see HTTYD 3 at our local cinema but it was only in 3D for one weekend, I was hoping to see it after work one evening. Gosh that’s not very scientific is it!!, looks like they are just driving home another nail.

Here’s the link to Nut job 2, I’m not sure of the region coding though if your not multi region,

Re: calibration; there would be a question as to whether the lamp iris was actually in the "true" position when calibrated or not. It might have just been in "a" position. To know this you'd need to reload the settings and compare the light output.

If you had a cheap meter and reloaded all the settings, doing a basic check of the gamma, gamut and white balance would give you a good idea if the calibration had moved across successfully.

Unfortunately it is all a bit black box and no-one (who publicly posts here on the matter) knows. The last time a service manual and procedures escaped into the wild was around the DLA-X3 age of projectors (6-7 years ago). This showed that at least one adjustment on having a new CPU board fitted required the use of a colorimeter to set, or an EEPPROM backup, which could lead to some fluctuation / omitted step that could render calibration settings sub optimal.

Your best bet would be trying to talk to an actual engineer at JVC or their service provider if possible who might be able to tell you exactly what the current procedures are when replacing a mainboar. Do feed back if you get some info out of them.

FYI this is from the old X3 service manual, so I'm sure this level of detail exists...

Sorry for the delay responding with the requested info - just a bit too busy on some other projects. I have attached what I think is the relevant information from the service menu.

For now I have decided to wait for another ChadB calibration visit in the future and not attempt to resurrect the projector settings.

Darn that same thing happens at my local plex too. Lots of times after 1-2 weeks they quit playing in 3D. Of the 8 houses only 2 are 3D capable.

Thanks for the link. I only can play Region Free or Region 1 discs. I do have The Nut Job 2 in regular 2D bd. I havn't done anything to my Oppo to modify its ability to play them yet either. I don't think I will.

Was looking and Im still waiting on The Grinch 3D. It doesn't release on 3D in the UK until the end of March so I double dipped and got the 4K UHD pack as well.

Have you guys found that, when going from an HD projector to a UHD projector, that your original screen works ok with the higher resolution? Or have any of you guys had to upgrade your screen too?

No need to upgrade here. My screen doesn't know it's getting a 4k image projected onto it.

I have had a couple of oppo’# in the past, I would definitely recommend the region free mod or even the external plugin mod which is about £60 in the UK.
We watched Small Foot 3D yesterday, it was ok but would of been better with stronger 3D for some pop out.

What is your serial number? We can turn this into manufacturing date.

Thanks. So far everyone Ive talked to has said about the same. I have a little worry in the back of my head on how my new RS540 will look on my screen once it gets here for another reason too. The first projector I used on this screen was a BenQ W7000 single chip DLP. With the DLP I could make out my screen weave in bright scenes but with the Sony LCOS it looked perfect. I think something about the DLP mirrors made my weave light up in a sort of moire pattern. Have never seen anything like that with the Sony 40ES and hopefully not with the JVC. If it does im gunna start shopping for a new screen.

I don't know much on the process of doing that, but Im almost tempted to do it. Ill look into it. Oh cool I loved Smallfoot! I made the mistake of buying it on BD before seeing if there was a 3D release or not. If I come across it cheap Ill get it in 3D. I double dip a lot in the pursuit of collecting 3D titles as well as UHD titles too.

Higher for main iirc it was 12.1.4 (there was a four in it)
And iirc higher for hdmi drv also. I'll check soon and take a pic for you. Not sure about the serial number but I'll check for that too.

Question regarding suggested settings based on calculator (projected) fL.

I will be throwing onto a 100" spandex screen (gain of approx .7)



Is this "too bright" or is that impossible? This will be a blacked out room.

I like bright image "pop" etc. and will get by with black levels as they are.

Any recommendation out of the box settings would be appreciated for the 540.

I have the X790 projecting on a 100" diagonal Studiotek 130 screen and have no issues with the brightness. For SDR I had to set the DI at -11 and that gives me plenty of brightness. For HDR I have the DI set at -2.

My SDR settings comprised of setting the black level and changing the default eShift settings. I believe I use 3 for the first one and have the other two set at 0.

For HDR you will need to learn how to use custom curves or refer to the first page of this thread for more settings.

With these projectors “too bright” is generally not an issue, as you can simply use the Manual Iris control to reduce the brightness to the intended level.

See the first post for suggested settings.

So I finally hooked up my Panasonic 820 to my RS540 yesterday. I had a UB900 previously. ChadB had calibrated the projector late last summer with custom curves.

So I do have the SDR settings that included a 2.4 gamma.

What is general consensus for setting up the 820?
Currently I have created a mode under User3
That is basically the SDR mode ChadB had done with the colorspace changed to BT2020 and then I also changed the DI from -9 to 0 with Auto 2.

I set the Panasonic to SDR BT2020 and set the Optimizer to ON. I liked the results for the little bit I had to use it yesterday.

Those of you that are using the 820 with a JVC in SDR BT2020, are you configuring in High lamp and maximum opening for the iris? Is high lamp necessary with SDR BT2020?

Unless I’ve got this wrong but I thought the Di was the auto iris and the manual Lamp iris was the one you manually adjust (-11 or -2 etc) ?.

In the manual setting it impacts both iris assemblies. They work in conjunction. In either Auto mode though I believe the Lamp Iris is static (does not change position) and only the lens iris is actively moving.

The manual iris works so that whatever you set the DI level to, for example -11 for SDR it means that the picture will get no brighter or darker then that setting. If you then switch it to Auto 1 or 2 then the DI will now be active and the picture will get no brighter then the -11 setting but will be able to get darker.

The wording was confusing. It should have said “Iris” instead of “DI”. The latter is indeed only controlled automatically.

Here is the software info. I have taken a pic of the serial number also. Is that something fine to post or...?

I dont have a way to calibrate yet. I live an hour from Chad B. so maybe i'll skip doing anything myself.

I have Nvidia shield working well pretty much out of the box using the SDR settings from page one on the thread. Watched FBI on youtube TV. Looked great for ABC air channel. I watched grand tour on Prime in HDR. Was watchable with the settings from page one. I will get custom curves going for that soon I think.

For movies, I have DSPlayer running MadVR. All the info seems scattered related to MadVR. Does anyone have anything to point me to get HDR tone mapping going? I'm not even sure what best JVC settings to start with. I believe I need some an add on or beta of MadVR for tone mapping?

Any help appreciated. This thing is amazing so far for the price.

Just another update on my exchange experience. My old unit has already been sent back, and the new unit is in position and adjusted but not calibrated. Have run it about 50 hours now.

Current status: I shouldn't have done the exchange. The convergence may be SLIGHTLY better overall, and the eshift noise has quieted down to about where my previous unit was. Bright corners don't seem to be an issue.

However, the one thing that really matters at the end of the day is focus, and this one is pretty terrible. The entire right 2' or so of my screen, if the center and left is sharp (and by sharp I mean as sharp as I can get it, it's still way less sharp than my previous), is blurry to the point of barely being able to see pixels. The bottom right corner is just a blur entirely, can't see pixels at all (with the center as sharp as I can make it). I actually can adjust the right portion of the screen to be sharp-ish, then the rest is blurry to the point of not being able to see pixels. It's almost like the lens was ground wrong. Sadly, compared to some of the pictures I've seen on here, I didn't even think my previous unit had as good of focus as was possible, however it was miles beyond this one.

I could easily make out the "4K" pixels on my previous unit when e-shift was on, not really on this one even in the areas that are focused the best I can manage. They just kind of blur together.

Worth noting, this unit is in EXACTLY the same position as the previous one so nothing has changed about the overall geometry.

I suspect a fight if I try for another exchange, they'll probably say this one is in spec, but given this one doesn't even have the purported iris fix (as there's another documented unit with a later serial number that failed), I'm pretty disappointed.

So, just did a pretty interesting test with my X7900 and profile off, engaging and disengaging the filter manually using the IR commands.

My X7900, in low lamp, loses approx 10% uncalibrated light output in Profile off mode when you flip the filter into the light path.
But if you use the RGB sliders to adjust the white point to D65 for profile off for each mode there is seemingly no loss of light output for white; this is because for filter off you have to adjust the sliders to remove yellow light which is in excess (have to reduce green and red to remove yellow). The light being culled by the filter really is wasted if calibrating to D65 and only useful for the purpose of getting a higher max (uncalibrated) lumens rating.

If there are light losses in the other (non profile off) modes this must be coming from the way the various modes are set up by the JVC internal colour management. But this does appear to show that on the X7900 at least if you can use profile off filter on mode with a 3DLUT you don't incur a brightness penalty. This makes it hard to see a downside to using the filter if you have access to a 3DLUT, because you also GAIN contrast thanks to the increased amount of panel dynamic range used and the improved black level.

I need to check that you can still hit the right colour luminance levels for each primary, but I'm pretty sure you can.

Has anyone else played about with profile off and filter on?

I really wonder now how the new N7 and NX9 fair (if they can also have the filter flipped in while in profile off mode).

Wait for Chad if you can. An hour away means if he's working around his home base you might find good availability.

See ya. Dave
