Version 4.0 adds High Dynamic Range (HDR) and Wide Colour Gamut (WCG) for both UHD and HD monitors. The HLG and PQ HDR Systems described in ITU-R BT.2100 are included.

To give Members clear guidance the Grade 1 Monitor specification has been split into 1A and 1B. This reflects the current capabilities of monitors to display HDR and WCG images. There are now four monitor grades: 1A, 1B, 2 and 3.

Can consumer televisions meet EBU Tech 3320?

They are unlikely to do so.

In general there is a large difference between professional grade monitors ("measurement devices") and Consumer Electronics (CE) devices. In practice CE Televisions may be close to EBU Grade 3 monitors in terms of display characteristics, but they typically differ from professional monitors in terms of interfaces and robustness.

Interface capabilities are evolving. For now the EBU requires HD-SDI interfaces as a minimum (see section 1.5.22). Users are advised to carefully check the capabilities of any other interfaces that may be provided (e.g. HDMI), as implementations may not support all desired formats.

See sections 1.1, 1.2 and 1.3 for more details.
