What is Dolby Atmos and HDR on streaming services?

HDR improves picture quality by showing more brightness levels and colours at the same time. Dolby Atmos improves sound by adding height and movement. Both need compatible hardware and the right streaming plan to work.

HDR (High Dynamic Range) makes pictures look more lifelike by showing deeper blacks and brighter whites at the same time, instead of one or the other. Dolby Atmos makes sound more immersive by placing audio above and around you, not just in front. Both are optional upgrades that look and sound better, but they require compatible hardware — your TV or soundbar needs to support them, and your streaming plan needs to include them.
