I’ve been wondering when this was going to happen. Just as widescreen TVs and computer monitors have become standard, more and more video footage is being shared, whether on broadcast TV, social media or whatever, that was captured on mobile phones in *portrait* mode. So you get the awkward problem of filling in the gaps on the sides of the screen with something useless but unobtrusive (heavily-blurred portions of the actual content seems popular right now), and wasting all that display resolution to boot. Seems like going back to 4:3 monitors, or even an orientation-neutral square 1:1 shape, is not an option. But Samsung has the solution: a TV that can rotate to portrait mode! <https://arstechnica.com/gadgets/2019/04/samsung-embraces-vertical-videos-with-a-16000-vertical-tv/>
