5120x1440 not displaying as ultrawide

Hello I’ve been all over the interweb looking for a solution but everyone who posts anything even remotely relevant is simply showcasing, not explaining HOW to get that view. I’ve tried nvidia panel, the Samsung g9’s own menu, pc settings, and SoT settings but nothing seems to fit the screen. So I’m stuct at a 16:9 ration with 2/3 the screen blacked out. I’m trying to get 32:9 but can’t seem to figure it out. Please help 🙈
