Continuing the discussion from How do I manually set video quality at streaming video sites?:
Hi, @CKrussell,
The proper way of doing it may vary from device to device, so it’s hard to find a definite guide on that.
I found these instructions on this website: How to Change Streaming Quality on Amazon Prime Video [All Platforms].
How to Change Amazon Prime Video Quality on Samsung Smart TV
If you own a Samsung Smart TV and want to change streaming quality on Amazon Prime Video, then you can head over to the App’s Settings Menu, then click on the Streaming option, and change video quality.
Check if there is an Amazon Prime app’s setting menu where you can change that. Sometimes the “gear” icon appears on the video window itself, on the right side of the bottom bar.
However, since you are part of the data saver
feature experiment, it’s probably not necessary to manually adjust the video quality.
