In the world of visual display technology, the demand for high dynamic range (HDR) monitors is steadily increasing. These monitors offer a wider range of luminance and color, allowing for a more immersive and realistic viewing experience. However, in order to fully utilize the capabilities of HDR monitors, proper calibration is essential. This article provides a step-by-step guide to calibrating BenQ monitors for HDR using the Calman software. The process involves the selection of a suitable meter, connection of an external source, and configuration of calibration targets. Pre- and post-calibration measurements are taken to assess the display’s grayscale and color response. The calibration process includes adjustments to the grayscale 1D LUT and color matrix or 3D LUT. By following this guide, users can ensure that their BenQ monitors are accurately calibrated for HDR content, resulting in optimal visual performance and enhanced viewing experiences.
Key Takeaways
- Calman software can automatically calibrate BenQ monitors for HDR by loading calibration data to the display’s internal 3D LUT.
- In order to calibrate the monitor, a compatible meter must be selected or searched for, and the appropriate meter mode should be chosen.
- A hardware test pattern generator should be connected to the computer running Calman for source settings, and the test pattern source device should be selected.
- The calibration targets should be configured to include Rec.2020/ST 2084 HDR (PQ) targets, with the whitepoint set to D65 and the ST 2084 gamma formula selected.
Calibration Process
The calibration process for BenQ monitors involves using Calman to automatically calibrate the display. This is done by loading calibration data to the display’s internal 3D LUT or using a combination of 1D LUT and color correction matrix. To begin the process, compatible BenQ monitors need to be selected and the appropriate meter mode for the colorimeter or spectrophotometer needs to be chosen. The hardware test pattern generator should be connected to the Calman computer, and the manufacturer and model of the test pattern source device should be selected. Calibration targets are then configured, with options such as Rec.2020/ST 2084 HDR (PQ) targets and preconfigured D65 whitepoint. Pre-calibration measurements are taken to measure the display’s grayscale and ColorChecker response. The desired display mode for calibration is then chosen, and the AutoCal button is pressed to begin the calibration process. Post-calibration readings are taken to document the display’s condition, and the calibration is saved to the monitor. Finally, the Calman session file can be saved and a report can be generated or additional validation tests can be performed. This entire process may take up to 15 minutes.
Compatible Monitors
Compatible BenQ monitors for HDR calibration include a range of models that can be automatically calibrated using Calman software, with the calibration data loaded to the display’s internal 3D LUT, providing precise color accuracy and enhancing the visual experience. These monitors offer a seamless calibration process with advanced features that ensure optimal HDR performance. Here are four key points about compatible BenQ monitors for HDR calibration:
-
Calman software enables automatic calibration, simplifying the calibration process and ensuring consistent and accurate results.
-
The calibration data is loaded into the display’s internal 3D LUT, allowing for precise adjustments to color accuracy and HDR performance.
-
The combination of a 1D LUT and color correction matrix can also be used for calibration, providing flexibility in achieving the desired results.
-
BenQ monitors support various calibration meters, including colorimeters and spectrophotometers, allowing users to choose the appropriate meter mode for their specific needs.
Source Settings
Source settings are an important aspect of the calibration process, as they involve connecting a hardware test pattern generator to the Calman computer, selecting the appropriate manufacturer and model of the test pattern source device, and configuring the necessary options such as the com port. This ensures that the calibration process is accurate and reliable. By connecting the hardware test pattern generator, it provides the necessary signals and patterns for the calibration process. Choosing the correct manufacturer and model of the test pattern source device is crucial for compatibility and accurate calibration. Configuring the com port allows for proper communication between the test pattern source device and the Calman computer. These source settings play a key role in establishing a stable and reliable calibration environment, resulting in precise and consistent calibration outcomes.
Post-Calibration Readings
After completing the calibration process, taking post-calibration readings allows for documentation of the display’s condition and ensures the accuracy and effectiveness of the calibration.
Post-Calibration Readings:
- Read Series: Click the Read Series button to measure the display’s grayscale and ColorChecker response after calibration. This provides quantitative data on the display’s performance and helps identify any remaining color inaccuracies.
- SDR Calibration Completion: Once the post-calibration readings are obtained, the SDR calibration process is considered complete. This means that the display has been calibrated to accurately reproduce standard dynamic range content.
- Saving and Reporting: To preserve the calibration settings, press the Save Config button to load the calibration to the monitor. Additionally, press the Save and Report button to save the Calman session file and generate a report documenting the calibration process.
Taking post-calibration readings is an essential step in the calibration process, allowing for the assessment of the display’s performance and ensuring that the calibration is successful. By following these steps, users can achieve a highly accurate and effective calibration for their BenQ HDR monitors.
