LG 2017 OLED & LCD Dolby Vision Calibration

I thought I'd take my post from the main LG 2017 OLED Calibration and Settings thread and start a dedicated post here. I'll start with a simple re-post and will add more detail and some attachments as I have time. If others want to share their experiences, ask questions, or add information, please do.

------------------------

3/23/2018 Update: Added link to the Intel GPU Configuration Guide

4/2/2018 Update: Updated with information from @zoyd that the HDFury Vertex works using the same process. and added a Requirements section.

4/19/2018 Update: Updated to include 2017 LG LCD televisions based on verification from @Anger.miki that it works with his TV.

For those wanting to brave the world of Dolby Vision calibration with your 2017 LG OLED/LCD TV, here's what you need to know:

After much help from @WiFi-Spy , I was able to get my Dolby Vision calibrated and CalMAN works beautifully for that purpose. It’s almost entirely automated and the thumbdrive configuration file load gives excellent results.

Requirements
  1. 2017 LG OLED or LCD Television
  2. CalMAN 2017 Home Theater (aka Home Enthusiast) or higher (click on the product box photos on this page to get the latest versions)
  3. HDFury Integral 4K60 4:4:4 600MHz or Vertex 4K60 4:4:4 600MHz
  4. HDFury Silabs drivers (4.0.0 or higher) and PC Windows GUI Software (Click on the Download tab in the above links to find them)
  5. 2 x HDMI cables (Certified HDMI cables recommended)
  6. Laptop PC with Intel Integrated GPU (Intel HD or later). Dual GPU / i.e. Integrated + Quadro do not work.
  7. FAT32 or NTFS thumbdrive with a capacity of 32GB or less
  8. Lots of patience
Lessons learned - At the moment NVIDIA Quadro GPUs aren’t working with CalMAN, only Intel (integrated) GPUs. I'm hoping this will change in the future, but for now, it's not supported.

Here are the settings & sequence I followed, which must be followed, EXACTLY, for those interested:

My Configuration Details
2016 HP Pavilion Laptop with Core i5 CPU:
OS: Windows 10 Fall Creators Update 2017 x64 (1709)
GPU, Intel HD 5500: driver version 15.40.37.4835
CalMAN 2017 Home Theater (aka Home Enthusiast) 5.8.2.85
X-Rite i1Display (OEM) purchased from SpectraCal
HDFury Integral 4K60 4:4:4 600MHz (02 hardware version)
Firmware version: 0.62.0.37
Silabs Driver 4.0.0
HDFury Integral GUI version 1.14
Certified HDMI 18Gbps cables between laptop & Integral & Integral & 2017 LG OLED65B7A TV

LG TV Settings
Cinema mode
Warm2 white balance
Follow instructions on this thread regarding turning everything "auto" or that changes the picture off, particularly Dynamic Contrast

Video Settings

Detailed Intel GPU Configuration Guide from @WiFi-Spy (summarized below)

Windows Display settings: scaling off

Intel Display settings:
  • General Settings/Basic:
  • Resolution: 1920x1080
  • Refresh rate: 24p Hz
  • Rotation: 0
  • Maintain Display Scaling Checked
  • General Settings/Advanced:
  • Quantization Range: Full Range
  • IT Content: Disable
  • Color Settings:
  • Color Depth: 32 Bit
HDFury Switch Settings
  • HDCP 1.4
  • Audio replaced from jack
  • EDID Fixed
CalMAN Setup Steps
  1. Warm up TV and position & warm up meter as well
  2. Connect your HDFury Integral via the Top Port if you have a serial starting in 02 or bottom port if your serial starts in 01, making sure the USB port is connected as well to power it
  3. “Extend” your Windows desktop to the TV
  4. Open CalMAN (ensure HDFury GUI is closed)
  5. Select Dolby Vision Custom Workflow
  6. Open HDFury GUI
  7. Select your meter (in my case the i1Display, with LCD LED as the meter mode - the OLED meter mode is for phone displays)
  8. Under Source, open the pattern window, drag it to the TV, and click in the center to maximize it
  9. Select Dolby Vision Relative Override for HDR Mode
  10. In the HDFury GUI, make sure your settings are as follows:

    • In EDID MANAGER tab: Under AUTOMIX:, only Allow YCbCR and HDR/HLG should be checked, and FIXED EDID should be selected based on the hardware setting
    • In HDR/IF tab: only FORCE HDR ALWAYS ACTIVE and Full HDR mode should be checked
    • Other tabs don’t matter
    • Paste (but don’t do anything for now) the follow HEX code into the CUSTOM HDR IF: field: 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
    • Confirm the following code is in the CUSTOM AVI IF: field: 00:08:00:00:00:00:00:00:00:00:00:00:00
  11. Click Next to advance CalMAN to the Verification of Correct Display Mode screen showing the correct and incorrect display. At this point, you should see the red/yellow test pattern on the TV
  12. Go back to the HDFury GUI and in the HDR/IF tab, click on the Send IF button
  13. The screen should now turn black with a white test box and the Dolby Vision should pop up in the upper right-hand side of the TV screen
  14. Click Next to read the overview of the DV workflow, then click Next again
  15. Now you're in the White Balance screen. Use the White Balance setting in the TV selecting the Low sliders for the 30% pattern and the High sliders for the 80% pattern. From my experience, it seems that the Red makes the smallest (read, best) adjustments, while the Green is a little coarse, and the Blue causes huge swings. Using the Read Continuous mode helps as it's a good idea to let the reading settle for 10s or so between adjustments. Shoot for the lowest delta E (dE) value in each measurement, and be warned, they do interact, so you might want to go back & forth until you get the best result.
  16. Once you have it dialed in, click Next to go to the Grayscale - Multi screen.
  17. Click on Read Series button to automatically read all of the points to see where you need to being your adjustments. Use the 20-pt white balance settings in the TV to fine-tune by manually select the luminance value you want to adjust in CalMAN and the TV. Re-run the Read Series to ensure you haven't impacted the other settings. Once again, shoot for the lowest dE, under 3, and ideally somewhere around 1 or less. Click Next.
  18. Next, you'll need a FAT32 or NTFS USB thumb drive. Insert it into your laptop, click on the Create Dolby Vision Config button. Once you select your thumb drive (don't put it in a folder, use the root, i.e. E:/) and click Ok, CalMAN will run an automated set of test patterns and a pop-up telling you it's finished "File written successfully" will appear.
  19. Insert the thumb drive into the TV, and turn on some Dolby Vision material (I just go to the Dolby Access app and select the first demo. A few seconds into playing the video, a pop-up message will appear on the TV asking if you want to replace the Dolby Vision configuration. Click Yes, and it will tell you that the settings will take effect next time you watch something in Dolby Vision. To be on the safe side, I stop and then re-play the video. Click Next.
  20. CalMAN will now tell you to switch the Source to Dolby Vision Relative Override in the HDR Mode. Click Next.
  21. CalMAN will verify your calibration, so click the Read Series button until complete, then click Next, Read Series until complete, and Next and Read Series one final time.
  22. Now you're done, so click View Report.
  23. Enjoy your favorite DV movie or TV show :)
If anyone has any questions, please let me know. I've learned a whole lot from all my troubleshooting and will be happy to share what I've learned.

Thanks again to @WiFi-Spy from Spectracal for the awesome customer support to get this working!

What laptop model would be good to install HCFR, Calman, or Chromapure for calibrating a LG OLED? I'm looking for a basic laptop to use primarily for calibration purposes, but with accurate video output (able to run UHD patterns).

Thanks,

Best bet is one with native HDMI port and Intel GPU.

A MacBook Pro retina with intel CPU and windows running on virtual box is going to work?

CPU or GPU? Currently, the GPU (graphics processor) has to be Intel. The CPU doesn't matter.
True and @MrRobotoPlus likely has an integrated Intel CPU/GPU, so he should be good. I'm trying to find Tyler's Video Card setup to attach to this post as he'll need to do that to get it to work. I put some instructions about the settings used, but Tyler's guide has lots of screenshots and is easier to follow.

I just want to make sure he has the proper GPU. If his computer uses an add-on card from another maker, he could be SOL...:(

Kudos to McGuyver for providing this great Workflow, it worked fine for me so far.

The "so far" said, because a friend ended up with a purple Image - by using a different workflow, that to be said.

I now have done all Steps until Step 18, so a USB Thumbdrive is ready to go, but before I go on i have two Questions.

1) If I end up with the same Issue (purple Image) ist there a way to roll back to my "old" Setting, by performing a Factory Reset?

2) As i have done some minor changes to RGB Levels in Step 15 to 17, do i leave them as set in Step 15 to 17, after performing Step 19 "Uploading the new settings"?
I am asking because until now i thought by uploading the File from the USB thumb drive, changes will take affect "under the hood", and by leaving the Settings as performed in Steps 15 to 17 I end up with double performing the changes a) via the File Upload + b) my Settings performed manually in the Steps 15 to 17.

PS: Special Kudos to TED for being such a great Guy and always helping me out over the last 2 Years!

1) My understanding is that you can reset the default DV settings by choosing "No" when you load the thumb drive and play DV material. Obviously you would have to play it again to do that, and I haven't done it, so someone else will have to confirm that. If you're friend is getting a purple screen, it sounds like there's something off on the metadata / Integral settings.

2) I'll have to check, but I think the WB settings get zeroed out when you load the DV profile via thumbdrive.

I have confirmed that the same process can be used with the HDFury Vertex.
Thanks, and I'll add that to the top post. That's good news as there are many more uses for the Vertex vs. the Integral.

Will get my hdfury integral in 2 days.
Anybody else had success calibrating DV? Anybody can confirm that the settings can be resetted if the calibration attempt fails (for whatever reason) ?

Dont want to screw up this, have a lot experience in calibrating displays - but DV is completely new to me, and it will be the first time I have the chance to do DV-calibration ;)
@MackGuyver
Maybe you should add the points that the display will drift like hell cause of the high luminance and heat it produces (at least I think that it will for sure)...
So:
1.Pattern Insertion Function should be enabled in Calman (I am using 50% full field window, every 10 seconds, duration 2 seconds while calibrating SDR)
2. Betwenn the readings (while analyzing the readings) you should feed some various content to let the display "cool down" (I have special "displaywash" pattern on my Pattern Generator)
3. Disable ASBL in SM if possible, turn back on after calibrating.

Maybe the more experienced calibrators can add something to this...

For HDR it's better to use much more "aggressive" Inseration Values

I recommend every 5 seconds a 10% Window (everything higher doesn't help to cool down the display and has the opposite effect) for at least 5 seconds.

Stupid question: is it possible to use a different pattern generator than the internal GPU? I am asking cause I have a RPi as pattern generator, but Point 11 says:

11. Click Next to advance CalMAN to the Verification of Correct Display Mode screen showing the correct and incorrect display. At this point, you should see the red/yellow test pattern on the TV

I think my PG cannot show this (only windowed pattern), or is it only to be sure that youre calibrating the right display and does not really matter? I can test that tonight, but maybe I can save time if anyone can answer me this question ;)
