Comparing an ultrawidescreen monitor to a normal 16:9 UHD monitor (3820x2160), the ultrawidescreen monitor has the same width but smaller vertical resolution. Everything you can do with the ultrawidescreen monitor you can do with the UHD monitor, and more due to the extra vertical pixels. Same goes for games. Games have an FOV slider. You can have the same FOV on the ultrawidescreen monitor as on a 16:9. The only difference is that the 16:9 monitor has more pixels vertically, allowing you to see more in the vertical direction. The ultrawidescreen is actually a disadvantage in this case, not an advantage, due to the missing pixels.
