My devices ( Xbox and Kindle), can't display 4k videos, which all tutorials now seem to auto-launch in. I get a scrambled green screen and it sometimes crashes my browser. I have to reset the video to 1080 in order to watch every single time. I've had a look in the settings but can see any way to disable 4k or launch at 1080 as my preference instead.
Does this option exist, or can it be implemented?
