2.4.2 Black Level
With a luma signal at black level (digital level 64 in 10-bit narrow-range. In ITU-R BT.2100 black level
for 10-bit full-range is defined as digital level 0, however in SDI-based systems digital levels 0-3 are
used for timing references and not allowed for active video), with a full-screen black test signal, the
luminance level measured from the screen in accordance with EBU Tech 3325 should be capable of
adjustment down to:
Grade 1A, 1B HDR Monitor: 0.005 cd/m2
Grade 2 HDR Monitor: 0.01 cd/m2
Grade 3 HDR Monitor: 0.02 cd/m2
