Measurement of Studio Monitors - Supplement 2

EBU Tech 3325s2

This Excel spreadsheet will assist you to calculate the Electro-Optical Transfer Function for (HLG and PQ) HDR when assessing monitor performance.

As the transfer functions for HDR are complex and cannot be represented by a single numerical figure, this Excel spreadsheet is provided to calculate the applicable tolerance in transfer function for HLG and PQ.

To use this Excel spreadsheet, enter the peak luminance and black level measurements and a plot of code value vs. expected luminance is created with acceptable tolerances. Please plot your recorded values on the relevant HLG or PQ plot and ensure they lie within the displayed tolerance limits.

Keywords: Professional Video Monitor, Performance Measurement, SDR, HDR, HLG, PQ.
