TCL TVs with 3D LUT capability offer a sophisticated method of calibration, allowing users to achieve a more precise and accurate picture quality. This feature is available in the TCL 2022 C735/C835/C935 series and the 2023 C745/C845 series. However, an essential firmware update is required for the 2022 series to access this capability. The calibration process for TCL TVs involves the utilization of an external Test Pattern Generator (TPG) or a direct HTML connection from the ColourSpace PC. LUTs can be uploaded via a USB stick, and profiling is conducted through an external patch generator, adhering to specific naming conventions for different types of LUTs. Additionally, Dolby Vision calibration necessitates the alteration of a user-edited .cfg file. To achieve optimal gamut calibration, a combination of 1D and 3D LUTs is employed, while only a 1D LUT is utilized for HDR and Dolby Vision calibration. Calibration data can be conveniently updated by uploading the relevant files through the TV’s USB port. For further guidance, calibration guides are available for reference, encompassing 3D LUT calibration and manual calibration. These advanced calibration options cater to enthusiasts seeking superior picture quality.

TCL TVs: 3D LUT Capability
The TCL 2022 C735/C835/C935 series and 2023 C745/C845 series are the only TCL TVs with accessible 3D LUT capability, allowing for advanced calibration options. These TVs stand out from other TCL models as they provide the ability to utilize a 3D look-up table (LUT) for calibration purposes. This feature enables users to achieve more precise and accurate color calibration, resulting in a superior viewing experience. Other TCL TVs do not possess this capability, limiting their calibration options. However, it is important to note that a firmware update is required for the 2022 C735/C835/C935 series TVs to enable this functionality. With the 3D LUT capability, users can unlock the full potential of their TCL TVs and enjoy enhanced color accuracy and image quality.
ColourSpace Calibration Process
ColourSpace calibration process involves using an external TPG or a direct HTML connection from the ColourSpace PC. The calibration process requires uploading LUTs via USB stick and disabling dynamic TV settings, while setting the Gamma to 0. It is interesting to note that full ColourSpace integration is planned for future TCL firmware updates. This means that TCL TVs will have a more streamlined and integrated calibration process in the future. This advancement will make the calibration process more efficient and user-friendly. Users will be able to calibrate their TCL TVs directly through the ColourSpace software, eliminating the need for external devices and manual steps. This integration showcases TCL’s commitment to innovation and providing advanced calibration capabilities to their customers.
Profiling Operation for TCL TVs
To achieve accurate color calibration for TCL TVs, the profiling operation requires the use of an external patch generator and the generation of correct metadata for HDR/HLG/Dolby Vision profiling. Any patch generator can be used for SDR profiling, but for HDR/HLG/Dolby Vision profiling, the correct metadata must be provided. After profiling, the LUTs can be uploaded to the TV using the TCL specific naming convention. It is important to note that 3D LUTs are not supported for PQ based HDR calibration and the 3×3 Matrix cannot be generated via ColourSpace. For Dolby Vision calibration, a user-edited .cfg file is required, which includes parameters such as Tmin, Tmax, Tgamma, and ColorPrimaries. The DV Config File should be uploaded to the TV’s USB port.
LUT Naming Convention
Utilizing a specific naming convention is essential when working with LUTs for calibration purposes on TCL TVs. This naming convention ensures compatibility and accuracy during the calibration process. When calibrating TCL TVs, it is important to adhere to the following guidelines:
- SDR, HLG, HDR, and Dolby Vision LUTs should be named according to the TCL specific naming convention.
- 3D LUTs are not supported for PQ based HDR calibration.
- The 3×3 Matrix cannot be generated using ColourSpace.
By following this naming convention, users can ensure that the correct LUTs are applied to the TCL TV during the calibration process. This level of precision and attention to detail is crucial for achieving optimal picture quality and color accuracy on TCL TVs.
DV Config File for Dolby Vision Calibration
The DV Config File is a crucial component for the calibration of Dolby Vision on TCL TVs, as it contains panel-specific parameters and metadata required for accurate calibration. This file includes parameters such as Tmin, Tmax, Tgamma, and ColorPrimaries, which are specific to the TCL TV panel being calibrated. The Tmin and Tmax values define the minimum and maximum display luminance levels, while Tgamma represents the gamma correction value. The ColorPrimaries parameter specifies the color primaries used by the TV. It is important to note that the DV Config File needs to be edited by the user to input the correct values for these parameters. Once the file is prepared, it can be uploaded to the TCL TV via the USB port for calibration purposes.
Using 1D and 3D LUTs
By combining the power of both 1D and 3D LUTs, users can achieve precise and accurate calibration results, ensuring optimal gamut and grayscale performance in their display systems. The use of 1D LUTs allows for pre-setting greyscale and/or gamma, while the 3D LUT is used for final gamut calibration. This combination of LUTs provides a comprehensive approach to display calibration, addressing both color accuracy and grayscale performance.
Benefits of using 1D and 3D LUTs for calibration include:
- Enhanced color accuracy: By utilizing both 1D and 3D LUTs, users can fine-tune the color reproduction of their TCL TVs, ensuring accurate and lifelike colors in their content.
- Improved grayscale performance: The use of 1D LUTs allows for precise adjustment of greyscale, ensuring smooth transitions between shades of gray and minimizing color inaccuracies.
- Optimal gamut calibration: The 3D LUT provides a detailed mapping of color values, allowing for precise calibration of the TV’s color gamut, resulting in vibrant and accurate colors.
- Fine-tuned HDR and Dolby Vision calibration: While only 1D LUTs are used for HDR and Dolby Vision calibration, the combination of 1D and 3D LUTs in the overall calibration process ensures optimal performance in these advanced HDR formats.
Overall, the use of both 1D and 3D LUTs in TCL TVs unlocks advanced calibration capabilities, enabling users to achieve the highest level of accuracy and performance in their display systems.
Uploading Calibration Data
To upload calibration data for TCL TVs, users need to navigate to the Picture/Advanced settings/Expert calibration/DDC/Import data menu and insert a FAT32 format USB stick containing the calibration files into the TV’s USB port. Once the USB stick is connected, the TV will detect and recognize the calibration data. The calibration mode will be renamed after the data is uploaded, indicating that the TV is now calibrated according to the imported data. It is important to note that for 1D LUTs, the user must manually remove the number of information lines in the file header. This process ensures that the calibration data is accurately applied to the TCL TV, allowing users to unlock the advanced calibration features provided by the 3D LUT capability.
