The EBU Tech 3374 calibration chart is designed to rapidly validate some of the most common issues encountered when setting up an HDR monitoring system.
This pattern allows users to:
- Validate that the monitoring system (from the input port to the displayed light) covers the specified dynamic range.
- Have a single solution to visually check all transfer functions independent of which EOTF (e.g. HLG, PQ, SLog3, etc…) and bit depth are used.
- Validate that all EOTFs deliver the same white point on the system.
- Troubleshoot the monitoring system for setup errors.
Note: This chart is NOT intended to accurately measure a display’s Dynamic Range. It is intended as a visual check that code values (CV) are output as intended. Please see § 3 for appropriate usage.
