The HD badge
Every poster carries the cream HD badge: the title exists in high definition on the services that stream it. What you see depends on the offer, your plan and your screen.
Resolutions
HD is 720p, Full HD 1080p, 4K 2160p, often with HDR. Big productions such as Avatar: Fire and Ash, Kalki 2898-AD or Interstellar are worth 4K; a comedy like Panchayat looks fine in HD.
Data
An hour uses about 1 GB in HD, 3 GB in Full HD and 7 GB in 4K. On mobile data, pick the data-saver setting in the streaming app.
