4k Fullscreen Borderless = 3200x1800 windowed?

[Alacrity Fitzhugh]

So, trying to make this game run full screen borderless on a 4k monitor, and it shifts to 3200x1800 windowed mode? Why? (4k Fullscreen works fine)

It's silly Unreal 4 shenanigans.

You need to set your desktop to 4K.

Edit gamesettings.ini for the correct resolution and Fullscreen=2

That will give you 4K in LiS:R
