Best FOV for FPS games when using a 4K 28 inch monitor?

[Daddy Gibby]

Title. I own a 4K monitor that is 28 inch wide. I have never messed with the FOV slider before, but I want to see what would generally be the best with what I'm using now.

Whatever fov means you enjoy looking at it.

What works for you might not work for me, so what works for me (70) might not work for you.

Like Zekiran said, it's down to personal preference. There's no "right" number, otherwise most games would just use that fov as default.
