I should note I misstated not being able to enter fullscreen mode, I can enter the mode, it just isn't displaying in a usable manner either in windowed or full screen.
The opening splash screen is normally sized, but when I pick any options, like generating a new world, after the message where you hit ESC at the end, the text completely disappears leaving the screen blank. I can zoom in and out but it's still off center, like this.

It's also somewhat the same in windowed mode, except instead of being stretched on the x and y axis, it's just excessively wide, about three times as wide as the monitor.
This is a generic, fresh Win10 install, and I've set resolution both in LNP and init.txt
[WINDOWEDX:80]
[WINDOWEDY:25]

You may disable window resizing if you wish.
[RESIZABLE:YES]
Full screen info. The 0s below mean that the game will choose a resolution for you, but you can set it yourself as well.
[FULLSCREENX:1920]
[FULLSCREENY:1080]

If this is set to NO, tiles will be stretched to fit the screen if there is a resolution mismatch.
If this is set to YES, the tiles will not be stretched, but rather the game view will be centralized, surrounded by black space. Tiles that are too large will always be compressed rather than running off the screen.
[BLACK_SPACE:YES]
I've also tried turning BLACK_SPACE:YES to NO to no avail.
And I can change tilesets, and text modes, but none of them, even 2D with or without TrueType are a usable size. While the visible area is different, it's still always unusable and never 1920x1080, which is what the display adapter's resolution is also set to.
