Thank you for all the info. After learning from your comment, it seems that would be an actual devices issue instead of the content/video issue.
I would have to advise you to contact the Help Team in live chat and discuss this further. As @ContentTeam and myself are not trained for devices output issue to provide you advices.
Thank you for your comment.
