This is so frustrating. Having to jury rig this system to get features that should have been included in the first place.
High Dynamic Range (HDR)
HDR video features significantly increased color range and enhanced contrast between highlights and shadows. This delivers picture quality that is much more vivid and lifelike.
At this time, HDR video is available on the following Amazon Video devices, for selected models from 2015 or later:
Samsung SUHD TVs, and Samsung Galaxy Note 7 Galaxy 8, 8+, Galaxy Tab S3 mobile devices
Sony Triluminos 4K TVs and Sony Xperia XZ Premium, G8141, G8142, SO-04J mobile devices
LG OLED and Super UHD TVs
Roku Ultra and Roku Premiere+ streaming media players
Internet Speed & System Requirements
You need an Internet connection of at least 15 Mbps to watch videos in HDR. You may also need to upgrade your device software to the latest version. For more information, go to About Updating Your Device Firmware.
Amazon Video Title Availability
HDR Amazon Video titles are offered in two formats:
HDR - HDR titles feature an "HDR" label as well as HDR purchase and viewing options in the video details.
Dolby Vision – Certain HDR titles feature Dolby Vision, which is the Dolby Labs HDR standard. For these titles, a "Dolby Vision" icon shows in the video details instead of an "HDR" label.
Note: Amazon Video supports Dolby Vision on selected 2016 LG TV models. If you don't have a supported device, titles offered in Dolby Vision are also available to watch in standard HDR format.
We’re continuing to expand our selection of HDR movies and TV shows, but not all Amazon Video titles are currently available with these playback options.
