Pretty sure the JVC allows setting a fixed IP in its config page, I just never had to do it.

I've never found any issues with black crush on any of the JVC models I've owned. Our eyes have limitations in resolving dark detail when other brighter objects are nearby. This can be a blessing in hiding defects like bright corners, streaking, and reflections but it also hinders calibration with certain patterns. Any patterns which simultaneously display bright elements like text labels on the screen will not work well for calibrating signal levels 17-18 on very high-contrast displays.

I suggest checking out these patterns I made for the OLED TV folks. You should be able to resolve down to 17 even with the default brightness and contrast settings when up close to the screen. Those lower levels are supposed to be very dark if your display is correctly tracking 2.4 gamma.

Sounds nice, Ix.

I intend to get to that. But for now I've just set the Vertex aside and will wait for other hardy pioneers to do the shake down work and a few more firmware updates from HDFury.

I did find it immensely useful, however, in seeing the exact HDMI signal and HDR meta data being sent while I was working on calibration issues.

Well I'm stuck leaving the house with the wifey for Christmas duties lol.

But in was able to sneak in a little more time with the projector. In the end, I had to set a specific ip address for the projector to connect to the internet correctly. Don't know why using the dhcp setting it could not auto config and pull it's own ip address.

Now that's resolved, onto the config files when I get home

Yeah, it's great for that. I have mine hooked up to my HTPC (USB power) even though chain-wise it's in between my AVR and PJ - makes it a lot easier to troubleshoot, update firmware, etc.

The new 1.9 firmware is out (I think you can only get the link in the Vertex thread right now, it's not on their page last I looked) and fixes a lot of auto-sensing problems. HDFury always takes a while to truly dial the firmware in but to their credit they work very well with owners and are always pushing features. We have the JVC RS-232 macro support solely because of members here.

My RS540 doesn't work with DHCP either, I had to hard set an address, for what it's worth.

ARVE TOOL INSTRUCTIONS
EASY / FAST METHOD



UPDATE AUGUST 2018 - 85 NITS PEAK VERSIONS FOR ARVE AND AUTOCAL - SEE HERE

UPDATE FEBRUARY 2018 - V3 CURVES ADDED - SEE THIS FOLLOWING POST FOR WHATS CHANGED

• I have placed everything you need in one folder on my Dropbox, it includes the tool, the curves, and Python:
https://www.dropbox.com/sh/t78y40ijf...4Qr3jevra?dl=0

If you want to download things individually...

• Download these instructions:
https://www.dropbox.com/s/jgqotnzpud...TIONS.pdf?dl=1

• Download the Arve Tool.
https://github.com/arvehj/jvcprojectortools/archive/master.zip

• Download the Arve curves for 1000nit and 4000nit peak white, put them in the same directory as the extracted Arve tool software.
https://www.dropbox.com/s/6vyu55o5he...urves.zip?dl=1

V2 Curves (January 2018) - 0 nits black level (Bar 64 is now black on the pattern) / Tweaked Highlight Rolloff / 1000 nit curve is now 1200 nit curve.
https://www.dropbox.com/s/v0c0t9fmo2...%20v2.zip?dl=1

V3 Curves (FEBRUARY 2018) - 0 nits black level (Bar 64 is now black on the pattern) / Tweaked Highlight Rolloff considerably / 1200 nit and 4000 nit curve.
https://www.dropbox.com/s/xbwz9fyt62...%20v3.zip?dl=1

V3 - 85 Nit Curves (AUGUST 2018) - 0 nits black level, these curves are very similar to the 100nit v3 curves but are designed for those with only 85nits peak white output. There is still a 1200 and 4000 nits version, both Arve versions (recommended so you can set perfect black level) and autocal upload versions.

https://www.dropbox.com/s/aqfg76574j...Curves.zip?dl=1

• Install python. Its the framework the Arve tool is built with, there is also an OSX version it seems but I have no idea if Arve tool will work on OSX.
https://www.python.org/ftp/python/3.6.3/python-3.6.3.exe

When you install it successfully, then Menu.py icon should look like this, and not just a white blank icon.



• Again, Make sure the extracted curves are in the same folder as the Arve tool files.

Select one of the USER Picture modes on the projector and set it up for HDR, copy the settings your HDR preset is using into this mode, that is because if you select the factory HDR picture mode you will errors in the tool when you try to write the Gamma tables since the tool does not recognise the 'new' HDR picture modes these projectors have. And then select a Gamma slot, Custom 1 / Custom 2 / Custom 3 Gamma - Do this with the JVC Remote..

So for my USER 2 profile, it looks like this:





• Make sure in the custom gamma slot you have selected on the projector you select Correction Value ‘IMPORT’



• Then open menu.py on the PC

A dos window will open,

• type lf 1000nit
(or, lf1200nitv2 or, lf1200nitv3 and so on for whichever files you are trying to loan in at the time - LOWER case L)

• then type Pw (case sensitive) to write the file to the projector.

• It should ask you for your projectors IP address, enter it, and it should work.





• Then on the JVC, select another gamma slot, Custom 2 IMPORT or Custom 3 IMPORT gamma slot, your choice,

• Type lf 4000nit

• Type Pw to write that gamma to the projector.

• You may get an error indicating the Arve tool does not recognise the projector picture mode and if you want to write anyway, just hit ignore. The newest models are not written into the Arve software just yet. If you g et this error make sure you are in a USER picture mode, these modes have less issues.

You are done.

OPTIONAL STEP
SETTING CORRECT BLACK LEVELS


UPDATE - USE THE V2 CURVES AND SET BBO FOR BAR 64 BLACK - BAR 68 FLASHING.


Please see the Waveform thread for more info on why.


HDR UHD Bluray Waveform Analysis

The only thing you may need to do is adjust your black level clipping with a pattern, (Masciola Pattern clip bar 77 and flash bar 81) or Sony 7669 HDR Pattern make bar 0.005 nits black.

I highly recommend buying the Masciola HDR10 Digital Pattern Suite, its $25USD. Small price to pay to get your HDR working the best it can:



http://diversifiedvideosolutions.com/dvs_products.html

If using the Masciola suite, use the pattern 02. BLACK CLIPPING_2_HDR10 to set your BLACK level to bar 64, meaning Bar 68 is very faintly blinking.

You may also want to check using the brightness control on the JVC once you have done that, how many clicks it will take you to reach bar 64 black (bar 68 blinking) since a very small portion of titles have raised blacks.



If you dont want to purchase the suite, all SONY UHD Discs have a secret calibration menu. While the UHD Disc is playing the main menu, type 7669 on the remote in quick succession, then a bunch of patterns should play, it will show a bunch of single colours first, hit next chapter until you see this pattern:

On the Sony pattern, bar 0.005 is what we want to be our BLACK bar, adjust until the next bar up is very faintly visible.



Now to adjust the black level in the Arve tool when you have your chosen pattern open:

To do that you will need the tool open and be looking at a pattern on the JVC. enter the changes, then type Pw again to write it to the projector live, and you can see what it did, still too dark, then try again, different value etc..
If you find the black levels are wrong, best check this with an HDR pattern, then you need to type ‘ga’ then ‘bbo’ after you use the ‘lf’ command and play with the values (these default to 0.0016 - try 0.002 to make the blacks brighter, and 0.001 to make them darker etc...)

That scenario would look like this:



Again you may get an error here, just hit ignore. Or if it asks to write anyway, hit YES.

I put these instructions into a PDF inside the Arve Curves zip file.

If you have a question please dont PM me about it, ask here in the open forum. I might not have the time to directly answer a ton of PM's

That's funny, why is it only in commandline? It seems to me, for the limited functions it provides, you should build a small GUI around that.

No probs.

I just edited my whole instructions, can you edit your post where you quote my old instructions?

You are too fast

These instructions are now in a nice clean PDF inside the Arve Curves zip file.

• Download the Arve Tool.
https://github.com/arvehj/jvcproject...ive/master.zip

• Download these curves if you haven't done so already, put them in the same directory as the Arve tool software.
https://www.dropbox.com/s/4of1twv73c...urves.zip?dl=1

• Install python. Its the framework the Arve tool is built with,
https://www.python.org/downloads/

When you install it, then Menu.py icon should look like this,



• Make sure the curves are in the same folder as the arve tool files.

• Make sure your projector is on and is in Custom 1 / Custom 2 / Custom 3 Gamma - Select this with the JVC Remote..

• Make sure in the custom gamma slot you have selected on the projector you select Correction Value ‘IMPORT’

• Then open menu.py on the PC

A dos window will open,

• type lf 1000nit

• then type Pw (case sensitive) to write the file to the projector.

• It should ask you for your projectors IP address, enter it, and it should work.



• Then on the JVC, select another gamma slot, Custom 2 IMPORT or Custom 3 IMPORT gamma slot, your choice,

• Type lf 4000nit

• Type Pw to write that gamma to the projector.

You are done.

OPTIONAL STEP
SETTING CORRECT BLACK LEVELS

The only thing you may need to do is adjust your black level clipping with a pattern, (Masciola Pattern clip bar 77 and flash bar 81) or Sony 7669 HDR Pattern make bar 0.005 nits black.

I highly recommend buying the Masciola Digital Pattern Suite, its $25USD. Small price to pay to get your HDR working the best it can:
http://diversifiedvideosolutions.com/dvs_products.html

If using the Masciola suite, use the pattern 02. BLACK CLIPPING_2_HDR10 to set your BLACK level to bar 77, meaning Bar 81 is very faintly clipping.



If you dont want to purchase the suite, all SONY UHD Discs have a secret calibration menu. While the UHD Disc is playing the main menu, type 7669 on the remote in quick succession, then a bunch of patterns should play, it will show a bunch of single colours first, hit next chapter until you see this pattern:

On the Sony pattern, bar 0.005 is what we want to be our BLACK bar, adjust until the next bar up is very faintly visible.



Now to adjust the black level in the Arve tool when you have your chosen pattern open:

To do that you will need the tool open and be looking at a pattern on the JVC. enter the changes, then type Pw again to write it to the projector live, and you can see what it did, still too dark, then try again, different value etc..
If you find the black levels are wrong, best check this with an HDR pattern, then you need to type ‘ga’ then ‘bbo’ after you use the ‘lf’ command and play with the values (these default to 0.0016 - try 0.002 to make the blacks brighter, and 0.001 to make them darker etc...)

That scenario would look like this:



I put these instructions into a PDF inside the Arve Curves zip file.

ARVE TOOL Instructions PDF here:

https://www.dropbox.com/s/d5dui0jisj...TIONS.pdf?dl=1

If you have a question please dont PM me about it, ask here in the open forum. I might not have the time to directly answer a ton of PM's
Thanks Javs that is a great write up. This may be a silly question but are there custom Arve curves for SDR or is it best to just use one of the Gamma presets?

There are no 'curves' for SDR... the best curve for SDR is a flat line

Stupid questions: I can’t load these with the JVC software can I? How do you decide which curve to use? Is there a way to set the PJ to default to a custom gamma or do I need to program some harmony macros?

Does the tool kit dial in red, blue and green individually to make sure they are equally adjusted to the same clipping values?

Yes of course, it uses the same table as the 33pt gamma autocal table. Full resolution.

For maximum accuracy, your projectors NORMAL base line gamma needs to be calibrated 33pt with the Autocal software.

The Arve curves are offsets to this baseline gamma and are not based whatsoever on the JVC's ST.2084 gamma. So if that is drooped or drifted, the arve curves are going to be incorrect also.

No, you need to load these using the Arve tool. You need to use the tool anyway to set your black level if you want to do it right.

In either the projectors HDR picture mode, or any custom mode you make, you can select whatever Gamma table you wish and the projector will respect the selection and not override it.

If you dont use the HD Fury Linker or other device to disable the HDR Autodetection, which is probably most of you, then you should set up the HDR picture mode with these curves sine the pj will switch to that picture profile when it detects HDR.

What I do,

Custom Gamma 1 / CORRECTION LEVEL / IMPORT is my 4000 nit curve.
Custom Gamma 2 / CORRECTION LEVEL / IMPORT is my 1000 nit curve.
Custom Gamma 3 / CORRECTION LEVEL / 2.3 is my SDR Gamma I use for all SDR content.

I leave it in Custom 1 majority of the time, or when I feel the content is a bit on the dark side (usually indicating the title is actually 1000nits not 4000) then its a quick hit on the menu button and then just hitting 'right' on the gamma tab and it will select custom 2. Couple clicks, really quick.

You could also obviously check the info screen to see MaxFALL/MaxCLL and if they are both well under 4000 nits then just select the 1000nit curve.

Just remember when you install these curves, and while using them, you NEED to select 'CORRECTION LEVEL' to 'IMPORT' under the respective Custom Gamma slot in the JVC.

Awesome guide Javs, thanks again. It took me a long time to piece that together on my own and you cleared a couple things up still.

Worth pointing out again that the (optional) section you list re: black level is imho important Also that if anyone wants to go to this level then autocal for baseline gamma, as you also point out, is seriously recommended.

I.e. it's not a magic solution for the average user that just makes HDR "better". The default settings that come with this new PJ line are actually pretty decent..... but if you have a meter, can calibrate gamma, get through using Arve's tool correctly, understand the basics calibrating black levels, etc. and (in my opinion) also have a Vertex so the profiles get loaded automatically and correctly based on the source... then this is the way to go.

If most of that doesn't apply then probably not worth the trouble to do only some of it. Could end up making things look worse, even.

Thanks so much for the excellent write up Javs. My 540 only has 40 hours on it but I plan to do the autocal 33pt at around 200 hours and then go through Arve again. I’ll also buy the digital HDR patterns you recommended.

Do you watch more HDR content than SDR? I would love to be to that point but there’s just too much for me that’s not HDR yet.

Nah most of what I watch is SDR since I watch a lot of stuff I have already owned over the years from bluray.

FYI the Arve tool once done never needs to be run again after you have done any calibration work.

I works on offsets to the existing baseline gamma and assumes from the start that your gamma is correct.

So there is no right time to play around with the arve tool, just jump in!

These are the two errors I got when trying to push a gamma profile to my projector.

This is the first error with just the projector on, nothing else.

After the first error, I thought maybe I needed a source to be on, just like how the JVC auto cal software will not connect to the projector unless there is a source input. After turning on a source, this is the second error I got when trying to push the gamma profile.

Do you have the picture mode set to user 1 or one of the other user locations when you run Arve?

I've not encountered either of those.

But, here's how I got success.

JVC on with a signal being fed to it which will neither go off nor change modes during 'the operation'.

Set JVC to User 1 Gamma Custom 1. (Or 'x' instead of "1" per your preference.)

*Then* start the Arve tool, load the .conf and write it to the JVC.


NOTE: I usually "ping" the JVC before starting the Arve tool just to ensure no network issues are present.

I'm an idiot.



Picture mode wasn't on user 1 or user 2. Could of sworn I had it on those modes.... but it was a long day of Christmas shopping so my mind is a little warped.


SIGH

both 1000nit and 4000nit are now pushed to the projector. Time for black adjustments

Thank you for your help!!!


So last question would be, how does ones decide if the 1000nit or 4000nit is more appropriate? Is it just preference or depends on how the HDR was mastered on the bluray? I assume I'd figure it out by switching between the two and seeing which one looks better while watching a movie. Just curious if there is a easier way to know before hand.
