CONFUSION
While HDR technology can greatly

become frustratingly complicated.
In fact, there are now four main
HDR formats: HDR10, HLG,
HDR10+ and Dolby Vision.
The only consistency comes with
HDR10. This ‘basic’ format is
supported by all HDR playback

sources. The HDR10+ and Dolby
Vision formats default to HDR10 on
displays that can’t support them.
Most TVs don’t support both,
despite sources typically being

other. So the HDR10+ Alien.
Blu-ray will only play in HDR10 on
LG TVs, as they only support Dolby
Vision. Samsung TVs only support
HDR10+ so don’t make use of the
extra data on Dolby Vision titles.
