Initial setup with Lumagen

To begin the initial setup process with Lumagen, it is important to ensure that the latest firmware is installed and that any communication issues are resolved by performing a Factory Reset if necessary. After this, the correct drivers should be installed if needed and the input/output signal cables should be connected to the Lumagen device. Additionally, the Lumagen should be connected to the ColourSpace laptop via USB or USB to Serial cable. This setup process is crucial for the accurate integration of Lumagen with ColourSpace for display calibration.

Initial Setup Steps
– Install latest firmware
– Perform Factory Reset if needed
– Install correct drivers, if necessary
– Connect input/output signal cables
– Connect Lumagen to ColourSpace laptop via USB or USB to Serial cable

Calibration process with Lumagen

Upon engaging in the calibration process with Lumagen, it is imperative to select the desired options via the Settings menu and establish a connection between ColourSpace and Lumagen Radiance through the appropriate COM port via Serial Port. To begin, it is recommended to reset the Lumagen to factory default using the remote control and ensure that no existing LUT is active by selecting Unity Bypass from the Select LUT option. Patch size and calibration patch selection can be set using the Calibration Patches option, either automatically or through the ColourSpace Settings menu. It is crucial to perform set-up checks, such as using a controlled video source to display a zero black image and checking for accurate black levels. The profiling operation involves navigating to the desired profiling mode in ColourSpace and using a probe connected to ColourSpace to measure the patches displayed on the screen. Finally, the Calibration LUT can be generated within ColourSpace and uploaded to Lumagen using the Select LUT option in the Hardware Options menu.

Patch size and selection

Patch size and selection in the calibration process involves configuring the desired patch size for profiling and selecting the appropriate patches to be displayed on the screen. This step is crucial in achieving accurate display calibration. Here are the key considerations:

  1. Calibration patch size: The patch size for profiling can be set automatically or manually configured through the Calibration Patches option. This allows for flexibility in choosing the patch size that best suits the calibration requirements.

  2. Patch color definition: Lumagen, in conjunction with ColourSpace, displays the patch color as defined in the Measure and Characterization menus. This ensures that the displayed patches accurately represent the desired colors for calibration.

  3. Unity Bypass data: Uploading Unity Bypass data may nullify all settings unless the "Disable input reset on NULL upload" option is selected. Care should be taken to ensure that the desired settings are not inadvertently overwritten during the calibration process.

Accurate patch size and selection are essential for achieving precise and reliable display calibration, allowing for optimal color accuracy and performance.

Configuration and set-up checks

Configuration and set-up checks involve verifying the correct settings and connections to ensure the proper functioning of the Lumagen system and its integration with ColourSpace for display profiling and calibration. These checks are essential to guarantee accurate calibration results. To begin, it is important to use a controlled video source to display a zero black image and check for accurate black levels by adjusting the In/Out HDMI options. Generating a New Unity Bypass LUT with a Gamma of 2.0 and uploading a Gamma Change LUT will allow testing of the Gamma LUT without affecting the zero black levels. Additionally, the Display Light Illusion BrightnessCal image can be utilized to assess the performance of the Gamma LUT. By performing these checks, any potential configuration issues can be identified and resolved, ensuring the integration of Lumagen for precise display calibration.

Profiling operation with Lumagen

When conducting the profiling operation with Lumagen, the user navigates to the desired profiling mode in ColourSpace, and the Lumagen system replicates the displayed color using the specified patch settings defined in the Hardware Options and Settings menus.

Profiling Operation with Lumagen
– Navigate to desired profiling mode in ColourSpace
– Lumagen mimics displayed color using patch settings
– Perform profiling using probe connected to ColourSpace and Lumagen
– Lumagen displays patches on the display
– Probe measures color accuracy of displayed patches

During this process, the user selects the desired profiling mode in ColourSpace, and the Lumagen system mirrors the displayed color by utilizing the patch settings specified in the Hardware Options and Settings menus. The user then performs the profiling by connecting the probe to both ColourSpace and Lumagen. The Lumagen system displays the defined patches on the display, and the probe measures the color accuracy of these patches. This allows for an accurate calibration of the display using the Lumagen system.

LUT upload and configuration

To successfully calibrate their display, users can upload and configure the desired LUT within the ColourSpace LUT Tools. Once the LUT is generated, it can be selected and uploaded from the Select LUT options in the Lumagen system’s Hardware Options menu. This allows for precise control over the display’s color accuracy and performance.

  • The LUT upload process ensures that the calibrated settings are applied to the display, resulting in accurate color reproduction.
  • By configuring the LUT within ColourSpace, users have the flexibility to fine-tune the calibration to their specific requirements.
  • The Lumagen system’s Hardware Options menu provides a convenient interface for selecting and uploading the LUT, simplifying the calibration process.

Overall, the integration of Lumagen with ColourSpace enables users to achieve highly accurate display calibration by uploading and configuring the desired LUT. This precise control over color accuracy is essential for users who seek innovation in their display performance.

How Can Lumagen Integration Improve the Accuracy of Display Calibration with Film Emulation LUTs and XYZ Profile Generation?

Lumagen integration enhances display calibration by providing precise film emulation LUTs generation and XYZ profile generation. This results in improved color accuracy and a more authentic cinematic viewing experience. With film emulation LUTs generation, the display can accurately reproduce the intended look and feel of films, preserving the filmmaker’s artistic vision.

Additional options in the Options menu

The Options menu in the Lumagen system provides users with additional settings specific to Radiance Pro and evolving UHD/HDR/WCG capable displays, allowing for further customization and optimization of the display’s performance. This menu offers a range of options that enhance the calibration process and ensure accurate results.

One such option is the ability to disable input settings reset, which prevents the system from resetting the input settings when a new LUT is uploaded. This is particularly useful when multiple LUTs need to be uploaded without affecting the input settings.

Another option is the ability to enable MODE with TPG, which allows the user to configure the system to use a test pattern generator (TPG) for calibration. This ensures consistent and reliable calibration results by using a standardized test pattern.

Furthermore, the Options menu allows the user to select the CMS slot, which determines the specific color management system (CMS) slot to be used for calibration. This enables users to choose the appropriate CMS slot based on their display’s capabilities and requirements, ensuring accurate and optimal calibration.

Overall, the Options menu in the Lumagen system offers a range of customizable settings that enhance the calibration process and enable users to achieve accurate and precise display calibration for their evolving UHD/HDR/WCG capable displays.
