Disney+ has been streaming movies with an IMAX aspect ratio for over a year and support for DTS is being added this year. It is still unclear when exactly this support will be available.
In the press release few details are shared from Disney, such as whether there will soon be support for DTS: X as a counterpart to Dolby Atmos, or whether it will remain with DTS-HD Master Audio or DTS 5.1. This addition will only be available at before Imax Enhanced certified devices, such as televisions from Sony and Hisense; not all televisions support DTS. In addition, it will be available through AV receivers from Denon, Marantz and JBL.
Disney + mainly broadcasts Marvel movies in the IMAX aspect ratio, which the company started in November 2021. These are shown with an aspect ratio of 1.9:1. This gives the films on TVs smaller black bars than with the regular versions, which have a wider 2.35:1 ratio. No specific supporting devices are required to watch movies in this unusual 1.9:1 aspect ratio. The IMAX Enhanced films also support Dolby Atmos, so viewers will probably soon be able to choose between DTS or Dolby Labs sound.
