Update on my progress:

I still can't get calman to recognize/connect to the Integral. USB error. Though I can see the correct entry in the Device Manager: USBExpressDevice.

Using the HDFury GUI, I have found that I can force the tv (2017 C7) into both HDR and HLG modes, so that is good progress. I found the infoframe codes by copying from the Spectracal article here: http://www.spectracal.com/Documents/...QuickStart.pdf

This infoframe will force HDR.

Once that worked, then I knew my hardware was working and it was a matter of finding the correct infoframe and AVI codes.

In the course of my searching, I found the infoframe for HLG:

87:01:1a:a3:03:00:c2:33:c4:86:4c:1d:b8:0b:d0:84:80 :3e:13:3d:42:40:10:27:01:00:10:27:fa:00

And that worked, which seems to indicate that the data from the beginning of this thread was not correct, at least for my television.

I am now searching for the DolbyVision infoframe data. I have typed and doublechecked the string from the first page of this thread.

I am now reading through the Vertex HDFury thread on avsforum.

Does anyone have any other suggestions?

Thanks

Latest update:

Following Skood's advice, I was able to connect Calman to the Integral after deleting the SiLabs driver. But, that meant that I could no longer inject the metadata to place the tv in DV mode because the HDFury GUI could not see the Integral at that point.

I've captured all my hardware specs and steps that I took so far, and emailed it off to Spectracal. Hopefully I'm just missing something simple/basic.

I open Calman and go to the Dolby Vision custom workflow. When I open Source, I can select HDFury and HDFury Integral 4k60 4:4:4 from the drop down. When I select Connect the following happens:

Error: Source not found. Check your USB, RS232, or socket connection.

Then Calman automatically closes.

Device Manager does show the HDFury as USBXpress and it seems to be installed correctly.

I have found that if I uninstall the SiLabs drivers, then Calman can connect to the Integral. But, then the HDFury GUI won't connect so I can trigger the Dolby Vision metadata.

All the specs:
Hardware:

Laptop: MacBook Pro Retina Display, mid-2012 edition running Bootcamp
Core i7-3720QM [email protected] with 8 GB RAM
NVidia Driver: GeForce GT 650M ver 416.16
HDFury Integral serial number starts with 02
Television is LG C7

Software:
Calman 2018: 5.9.1.76
SiLabs drivers Ver 4.0.0
HDFury Integral Firmware: 38 (065038)
HDFury Integral GUI v1.14

I have configured my laptop following the instructions from Tyler Pruitt here:

https://www.dropbox.com/s/nwsmfssbw7...Guide.pdf?dl=0

And also the AVSForum thread here:

https://www.avsforum.com/forum/139-d...libration.html

I was able to successfully put the LG C7 into HDR mode with the Integral by following the instructions here:

http://www.spectracal.com/Documents/...QuickStart.pdf

And I was able to invoke HLG by changing the HDR Infoframe with values I found for that.

But, I am unsuccessful with Dolby Vision. Here are the values I'm using:

Infoframe: 81:01:18:36:03:0c:00:20:01:00:00:00:00:00:00:00:00 :00:00:00:00:00:00:00:00:00:00:00:00:00

Custom AVI: 00:08:00:00:00:00:00:00:00:00:00:00:00

Does it matter if I use the top or bottom HDMI port on the Integral? I've tried both.

After much more fooling around with this, and some help from Skood, I'm thinking the problem is my laptop. I'm using a mid-2012 MacBook Pro Retina with the NVidia 650M GPU.

Does anyone know if this laptop will work for Dolby Vision calibration?

My next step is to hit eBay for a compatible laptop.

I have had success getting Dolby Vision working to calibrate my C7 with my mid-2012 MacBook Pro Retina display.

Thanks to MackGuyver for starting this thread, and WifiSpy for his help to me along the way.

My equipment was:

LG C7
MacBook Pro Retina mid-2012, with integrated NVidia 650M GPU
HDFury Integral, first edition, serial number starting with 02

Here are the key things that I struggled with:

On the MacBook:

NVidia:

Latest driver 416.16
Control Panel ver 8.1.940.0

In the control panel set:
Resolution > 1920x1080; 24Hz; 32bit color; 8bpc; RGB; Full Range
Size > No Scaling button checked; GPU Override checked
Video > Color set to NVidia; Advanced > Full 0-255

Windows10 > Settings > Display

As mentioned before, 1920x1080 in Extended mode. Here's where I got hung up. There are two places to set the scaling in Win10. Here, and also in Advanced Scaling. I had to set Advanced Scaling to 100 and restart the machine. Once I did that, I was able to send the IF string in the Integral GUI. Without this, I could send the string, put the C7 into DV mode, but not pass any video.

HDFury Integral:

I had to put the EDID hardware slider on AutoMix. Doing this from the GUI was ineffective, and setting the slider to EDID Fixed did not work for me.
HDCP slider set to 1.4
Audio slider set to Jack

In the EDID manager, I had Allow YCbCr checked, along with HDR/HLG
In the HDR/IF section, I only had Full HDR mode checked

I am using the latest firmware for the Integral: Version 065038
Also, the 4.0 version of the SiLabs driver
HDFury GUI ver is 1.14

The custom HDR IF I used was: 81:01:18:36:03:0c:00:20:01:00:00:00:00:00:00:00:00 :00:00:00:00:00:00:00:00:00:00:00

Note that there is an extra space in the original post of this IF.
I did not need a custom AVI IF field.
I only had to send the custom HDR IF once. I did *not* need to have the Force HDR Always Active box checked.

After all that, the calibration was as mentioned. I could have saved myself some time/effort by disabling ABSL, but didn't think to do that.

One other thing of note was that I did edit the config file to set the Tmax value to match the value at 100 IRE. I saw D-Nice mention this and it did the trick for me. Prior to doing that, my post-calibration settings were a mess.

I set the Color to 80 and also tweaked the CMS just a little.

Hope this is helpful to someone. I'm happy to answer any questions. I'm not an expert, but have spent 40+ hours getting this to work.

Looks like you have done only rgb balance but not gamma correction?

You left color at 50?

Good catch. I messed up the screen capture. Fixed that.

Also added that I set the Color to 80. I started with 76 as recommended in the OLED calibration thread, then tried higher and lower to see where the error was lowest, then tweaked the CMS a little bit.

Hi, increasing so much the color slider, from 50 to 80, its a chart fix, its not a real fix of the problem.

The TVs are not suffering from any luminance or undersaturation issue in DV mode when they are using the default factory generic DV file LG is loading inside to panels, the problem appear when you will load a DV file CalMAN generates. If you perform manual cal of DV and not load any CalMAN DV file, you will have better results and it will not require to touch the color slider.

There no instruction to any CalMAN DV workflow, which will say to increase the color slider after the calibration from 50 to 75-80 range, so this workaround it a chart fix only users find out after spending many hours.

When you measure Color Checker in DV all color patch values have below 100 nits target luminance (because they have 50% Stimulus level all the targets), so adjusting so much the TV color slider, it can improve the charts when you measure below 100 nits, but increase the errors to higher luminance range since that large adjustment will clip the colors.

How LG with Dolby calculated that DV data file which not introduce any color gamut undersaturaton/ low luminance problem and any CalMAN DV data file is introducing these issues?

Does the purpose of calibration is to reduce dE so to have more accurate colors? But with that CalMAN DV procedure we have more color gamut errors, not only a few more, but a lot of more colors errors (+ 3-6dE range in gamut) more than without calibration at all, just the grayscale tracking is improved only.

Its clearly from all user posted data (I'm excluding any data from my end) that post color gamut performance is worse and since there nothing to do (no CalMAN workflow suggest to do anything after you will load the DV file), users find out that by adjusting manually controls after the AutoCAL DV calibration procedure and tone mapping calculation bla bla), other user are adding color, others are editing manually DV config files with other peak output numbers etc.

Does the initial notice for HDR calibration was to not touch contrast/brightness/color/OLED Light, because based to these settings the internal tone mapping work, right? (they work as bypass settings), so because results were not good now we are changing plans and recommend to use a color setting which looks better?

LG Engineers and CalMAN Devs must pay more attention and spend much time on testing before they release such features, in the calibration world we need solutions that work, if they don't work, they should not be released...or improved first internally and then being released.

A CalMAN DV PDF file has to been written (it has to be written from 2017, now in one month the 2019 models will be announced) also to describe the steps of DV calibration/setup using CalMAN Software Patch Generator + HD Fury Integral (which has been discontinued already....CalMAN has to add support for Vertex/Integral 2...the API for Vertex is a lot of months out to HD Fury site for developers to download).

At lease there a lot of valuable/helpful info to this thread about how to setup (from users).

Thanks for the detailed post. I have a couple questions. I am asking from a perspective of seeking to learn, and in no way disputing anything you posted.

I have read many times not to adjust OLED, Brightness, Contrast on HDR, but never saw a reference to not adjusting Color. Is this true as well?

What would be the best procedure for those of us who want to attempt DV calibration?
a) Use the Calman workflow and just not adjust color?
b) Reset to factory defaults, then place the C7 in DV mode and adjust only the greyscale? How would we do this without using the thumbdrive procedure to upload the new file?

Thanks for your help.

Yes, its true, Color will affect the gamut mapping.

CalMAN workflow don't say anywhere to adjust color after uploading the CalMAN's generated DV file inside the TV. Its users trick to improve the charts, not official workflow approach.

Since the default generic DV file any TV has inside provide better gamut tracking from the one CalMAN generates, but the factory Grayscale is not that good, you can try to display 10% Window Grayscale HDR10 patches and enter to Service Menu to adjust White Balance of Medium color temp which will affect the White Balance of DV mode also when you will select Warm1 color temp.

Hi,
Just got the HDFury Integral 2 and trying to make it work following the guide. I’m able to trigger DV but the screen shows nothing is just black, I can only see the DV pop up then nothing. HDR is working. Any kind soul can give me advise on this?

I cant get anything to work. I dont see a Dolby vision logo. I get to the red and green incorrect screen, try to inject the HDR IF and get an error message. I'm stuck and lost.

I try to follow the steps as close as possible but not sure if I'm missing something as my laptop setting dont mimic the ones in this thread at all

::Error Writing Infoframe values:: is what i get every single time. I feel like i just wasted 250$ on this damn thing

I may be able to help. I have to run to work now, but faced the same challenges.

Are you using Windows 10? See my post where I say you have to make sure both places in the Win10 Settings are set to 100% screen size. Once I did that, everything worked. I fought the same red/green issue.

PM me if you want to discuss more. I'll be late tonight, but may have more time tomorrow evening.

Are you using Windows 10? See my post where I say you have to make sure both places in the Win10 Settings are set to 100% screen size. Once I did that, everything worked. I fought the same red/green issue.

Thanks Jon,

But I'm an idiot. After 5+ hours of fiddling around and giving up, I took the damn thing to work and just realized that the USB plugs were labeled and I had them inserted backwards. I'm back home this morning and will begin again, with everything hooked up correctly to see where I get. If I run into anything I'll shoot you a message.

Thanks again

I have this problem. I use WIN 10 and settings are 100% and 100 for custom scaling. DV is triggered but the screen is blank, no video. Maybe I have to set up the Integral in Calman as the source? this won't work I got an email today from spectracal support saying that integral2 desn't work with Calman in anyway.

This is the problem I am having now too. After setting up everything correctly, I throw my display into Dolby vision. The Dolby vision logo appears and disappears over and over and the screen remains black. Anything I extend to the TV from the laptop can not be seen, but can be extended.

Do you both have the Integral 2? I was using the Integral 1 (gold color).

Also, review my post. I found success by using slightly different settings than the thread starter for the Integral button positions.

I'll have more time on SAT to review with my own gear if needed.
