The Aorus FO48 supports ultrawide resolutions, and because of its overall size of 48 inches would actually be bigger, than other ultrawide monitors out there except a particular 49 inch samsung ultrawide monitor. A 34 inch ultrawide monitor would have a substantially smaller picture than a 48 inch 16:9 set to ultrawide resolutions. So why not have the best of both worlds?
If using ultrawide resolutions on an Aorus FO48U, you would have black bars above/below the picture, however being an OLED the bars would be pure black devoid of any light bleed, and therefore cause no distractions. see here: My New Gaming Monitor - AORUS FO48U - YouTube
I have zero regrets with this panel.
