Select the picture version on the film page
Disney’s help says selected films use the expanded aspect ratio automatically, either throughout the film or only in selected sequences. Where offered, the Versions tab provides IMAX Enhanced and Widescreen choices. Read that tab’s description for the specific film.
If the picture changes shape partway through a film, check whether it has selected IMAX sequences before changing the television’s zoom. A mixed presentation is not automatically a display fault. Compare the chosen version and the relevant scene rather than expecting every frame to occupy the same area.
Check the sound format independently
The reviewed help says the expanded picture is supported on Disney+ supported devices, while IMAX Enhanced sound with DTS: X is restricted to selected Android TV devices from named manufacturers. It also excludes With Ads plans from that sound feature in the reviewed guidance.
Open the film’s Details to inspect its audio formats and look for the DTS: X badge where available. A manufacturer’s name alone is not a model-level compatibility check. Confirm the actual television and applicable plan rather than assuming that every device showing the IMAX label can output the associated sound format.
Change one relevant condition at a time
For a picture complaint, record the chosen version and whether the film description promises expanded framing throughout or only in particular sequences. For a sound complaint, record the listed format, exact device model and current audio route. These are different evidence sets.
A useful comparison keeps the same title and scene while checking the relevant setting. Buying audio hardware solely because an IMAX picture version plays would skip the device and plan checks. Conversely, missing DTS: X does not require abandoning the expanded picture if that version otherwise suits your viewing. Use Disney’s current device-specific instructions for the audio route you actually own.
Questions about this guide
Does expanded IMAX picture prove DTS: X support?
No. Disney documents broader picture support and narrower sound requirements.
Why does a film expand only during some scenes?
The help says some titles contain selected expanded-aspect-ratio sequences rather than using that framing throughout.
