ColourSpace can be integrated with LG WOLED TVs for accurate Closed Loop display profiling and calibration.

  • ColourSpace Integration
  • Closed Loop Profiling
  • 3D LUT
  • High-level accuracy
  • DeviceControl Management

Compatible LG TVs include the 2022 C2/G2/Z2/B2/A2, 2021 C1/G1/M1/R1/Z1 (and potentially A1/B1), 2020 BX/CX/GX/WX/ZX, 2019 B9/C9/E9/W9/Z9/R9, and 2018 B8/C8/E8/G8/W8, and 2017 B7/C7/E7/G7/W7 models with Technicolor Studio Firmware.

All ColourSpace users can attain Advanced User Guides for calibration of LG TVs from the Customer Downloads page.

ColourSpace Integration

LG TV operation and function is controlled via the Hardware Options menu, accessed via the Profiling window.


Initial Setup

  • Connect the LG TV to the same network as the ColourSpace laptop, and start ColourSpace
  • Connect the desired TPG to ColourSpace, and connect the TPG output to the HDMI input of the LG TV
    (Assuming the internal iTPG is not being used, due to it not being bit accurate)
  • Set the desired set-up options via the Settings menu, as required
  • Open a first ColourSpace Profiling window, select Hardware Options, and select LG from the Hardware drop-down list
  • Enter the TV's required IP address, and select Connect
  • Open a second ColourSpace Profiling window, again select Hardware Options, and select the required TPG from the Hardware drop-down list
    (Refer to the relevant TPG User Guide for further operational information)
  • To make sure there is no existing calibration data active within the selected Load/LUT/Slot, and associated colour space selection, etc., select Unity Bypass from the Select LUT option, and press Upload
  • The Reset Picture Mode option can be used re-set the selected Profile and all associated LUT and colour space options to the TV's defaults

When Unity Bypass Upload is used only the selected LG Options are effected, with different internal TV parameters being effected depending on the selection of 1D or 3D within Load options.

Profiling Operation

While LG TVs can be calibrated using ColourSpace via a LUT upload, the actual profiling should be performed via a an external patch generator, due to the internal TPG not being bit accurate.

Any patch generator can be used, including direct HDMI/DVI/DisplayPort connection from the ColourSpace laptop.

LUT Upload

After profiling, a Calibration LUT can be generated as normal within ColourSpace LUT Tools, and saved into the library.

With the LUT still held within ColourSpace navigate back to the Hardware Options menu, and select the desired LUT from within the Select LUT options, and Upload into the desired Picture Profile.

There are two LUT slots available with the LG TV, with the 3D option being the normal configuration to use for display calibration.

  • 3D
  • 1D

When a 3D Unity Bypass Upload is performed, the TV's on-screen controls, such as Gamut & Gamma, as well as white balance controls, etc., will be disabled and the processing set to bypass, as they will be defined by the 3D calibration LUT.

The back 1D LUT can be used to pre-set a display's greyscale and/or gamma as a first pass, and then the display can be re-profiled with the back 1D LUT active, and the 3D LUT generated from the second profile pass uploaded to 3D only for the final gamut calibration.
(Note: If using a 3D LUT in conjunction with a 1D LUT, it is imperative Unity Bypass Upload is performed for both 3D and 1D Load options, before any profiling is performed.)

Alternatively, the 1D option can be used in isolation, without first performing a 3D LUT Unity Bypass Upload, and will leave access enabled to the TV's internal gamut management and leave associated signal path processing active, allowing just the 1D LUT to be modified in conjunction with selected TV controls and settings.
