A traditional monitor is 16:9: that means for every unit of height, there is 1.77 units of height.
It sounds like a small difference, but it means a ~15% increase in height.
ex. my Visual Studio Code would show 70 lines of code instead of 60.
This is an especially good tradeoff for code, because we tradtional line wrap at ~80 characters, which leaves large swaths of width available.
