I've seen some torrents incorporating both standards in their description and I don't get it. It's either 1200p (1920x1200, WUXGA) or 1080p (1920x1080, Full HD).
Yes, I've seen a video file that changes resolution mid-video, but it's more of a party trick since not all players handled it well
Specifically, I saw a group chat program rendered it "correctly" (Discord? I don't remember), so the embedded video would re-flow the rendered chatroom while playing
