I personally have the Xiaomi 34 inch ultrawide monitor and the size is perfect. It covers up so much of your peripheral when you are watching movies or playing games.

Most games and movies can fill up the entire screen even on the 21:9 aspect ratio.

Keep in mind when you get such a wide monitor it’s going to have a really wide stand as well which can cover up your desk quite a bit.
