I think it's only 150%, currently running windows on a 28" 4k monitor makes me think 200% would be too much?

Oh I should also add that I haven't ever had any of the DPI issues the parent's parent is referencing. The only problem with multiple display DPI in Windows 10 is the shockingly bad fuzz you get on your secondary display from the thing being rendered either smaller or larger than normal (depending on whether the 4k is your primary or secondary) and then scaled up or down to fit the monitor.

It may somehow be detecting the size of the display. My 13" laptop likes 250% scaling, while my 27" monitor likes 150%.

That would make sense, your DPI scaling is all to do with readability after all :)
