JVC v3.50 firmware

[AVSCraig]

Had same issue with 3 usb thumb drives of various sizes. None worked but a memory card adapter.

That's odd, but whatever works.

I have had difficulty loading updates since the day I received my NX5 last April.  JVC's USB implementation is awful.  I have tried no fewer than seven USB A 2.0 and USB A 3.0 thumb drives as well as multiple computers, all of which fail.  The only thumb drive that actually works is a Vivatar SD/MicroSD USB A/C thumb drive.  JVC technical support is not particularly helpful and acts as though you are either obtuse or incompetent, when it is JVC's poor hardware or software engineering that creates the issue.  This is the first JVC projector I have owned, and am unimpressed with the quality.  The out of the box calibration was awful and I had a bulb explode after nine months of use.

It seems that when you get a USB stick that works set it aside somewhere where you can use it again. My ritual is make sure the projector has been off a few minutes, then turn it on and wait about 5 seconds then plug the USB stick in the service receptacle and clap your hands three times, jump up and down two times, and spin around once. You can probably skip the last three steps but prayer sometimes helps .

It is spin around once clockwise and twice counter clockwise. As other said, once you find a USB that works, set aside and use anytime you need to update. It will work every time.

From JVC - If your using Auto Cal, be sure you turn off the screen adjust.

I had done an Auto Cal, and noticed that I still had a red push. On checking, I had mistakenly left the screen adjust “on” with code 114 for SI Slate 1.2. As soon as I turned screen adjust “off”, the push went away, and I had a nice, neutral grayscale.

It helps to have a test disc or other source with a gray pattern you can use to check this.

Depending on the code that was being used, this could also manifest itself as a green or a blue push.

Is there maybe an overview of these bug fixes? It is mentioned that some(?) of the settings might be reset to factory.

Thanks in advance.

V3.10 to a newer firmware resets many things. V3.50 to V3.52 should not.  


Always take a photo of any important settings.  Even if you never do a firmware update!  Just in case.


There are a variety of small bug fixes from V3.50 to V3.51 to V3.52 that make V3.52 worthwhile.  It fixes an issue with auto cal., and  a possible HDMI synch issue which a few people have experienced.

Thanks for your feedback!

I read somewhere that v3.51 also solved an issue for users with an external scaler (like Lumagen or Envy MadVR) that installed v3.50. Is this true?

Thanks in advance,

It's my understanding (I could be wrong) that neither 3.50 nor 3.51 changed anything with respect to easily configuring the HDR Auto-select Picture Mode for use with the Envy or Lumagen - specifically assigning a 'power' gamma like 2.4.  To do this, you need to use the Autocal Software to have an Imported value of 2.4.

I would like to be surprised that 3.52 fixes this, and makes it easy to assign a power gamma, but I'm not expecting this.

I'm thinking this is probably what you were asking about, but again I could be wrong.

Will not reset the settings.

This is indeed the background of my question (and it is also good to know what bugs are solved... my reasoning: “If it is not broken, do not fix it”). I read in the MadVR manual that they strongly discourage(d) to install firmware v3.50.

Currently I am not using an external scaler yet (I am considering to purchase one). As mentioned, I heard that v3.51 would enable an easier use of an external scaler than going back to an previous version of 3.5.

Best regards, Jan

If you're considering an Envy or Lumagen, there is nothing to be gained by doing to 3.50, 3.51 or 3.52.  These provide improvements in HDR performance with the Theater Optimizer.  But if you use the DTM from either device, you won't be using that anyway, so there's really no point.

I'm on 3.10, with no plans to update, as to the best of my understanding, there is nothing that I would gain, and configuring for the Envy is more problematic.

There are vague references to Autocal tweaks, but until JVC explains in greater detail just what this means, so I can decide if there's anything of real value for me, I'll stick with 3.10.

I purchased my NX9 at the end of last year (so it is was delivered with v3.50 installed). Reason for asking. It would be nice to ‘quickly’ check the performance while comparing with and without an external scaler (and preferably in my own situation). Although many people say that an external scaler is even better, I can hardly imagine  (but there is only one way to find out). For now I decided to change nothing yet, but maybe in the near future it would be nice to do such a shoot-out.


Best regards, Jan

The Envy/Lumagen can still be properly set up to work with 3.5x firmware - it just requires some extra effort with use of the free JVC Autocal software.  So not a big deal.  But I still wish JVC would make the slight change that would be needed to make it as simple as it is with 3.1x.

Making direct comparisons of JVC's DTM vs Envy/Lumagen DTM, in your own home, would be great if you can manage to work that out.  Given that the JVC would need to use different Picture Modes, with an HDMI handshake required, you won't be able to go back and forth between the 2 instantly.  But hopefully quickly enough that you can still make useful comparisons.

I don't recall if you do, but if you have a Scope screen, that would be a pretty big incentive to use an external video processor.  The black bar detection simplifies watching content with any aspect ratio, and in particular with the Envy, has superb ability to handle Subtitles with scope content (if that's important to you).  And if you have or add an A-Lens, the benefit increases even more.

Just trying to spend your money!!
