• Download the Arve Tool.
• Download the Arve curves for 1000nit and 4000nit peak white, put them in the same directory as the extracted Arve tool software.
• 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.
• 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.
• 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.
• 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.
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.
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:
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.
