Hello to All, hoping to get some feedback and advise on this matter. I currently have a Samsung 4k TV, not sure what model offhand, using the Onn 4k box. My go to app for streaming is Stremio/Torrentio w/ RD. I try to choose a 4k stream whenever there is one available for the content I want to watch. But when I start the stream, just before the video starts I get a pop-up message like the one in the picture below. Obviously, that resolution is for FHD and not 4k (3840 x 2160). What can I do, if anything, to actually view the video in 4k? Is there a setting i need to change somewhere? Should I be using an external player, ex. VLC or MX Player Pro? Do I need a special 4k HDMI cable from the Onn to my TV? Looking forward to your replies.
