Minecraft won't fill my monitor when I play in fullscreen. It claims to still be running in 3840x2160 (my native resolution) but it only takes up part of the screen.

I found a solution that worked for me! If you can see the image, make your compatibility settings look like that. (I'm not sure which settings actually solved it, im just happy that it works now)
I turned on Override high DPI scaling behavior Scaling performed by: *(set to Application) and I disabled fullscreen optimizations.
i also ran as administrator, probably won't change the results however.
from what I know, Mojang changed the code relating to fullscreen in version 1.13.0. This causes java to be unsure of how to display the image when going back to earlier versions. I don't know how to fix the issue but hopefully, this helps in some way. I'm currently having the same problem and i will update you on this when I get it fixed.
Hey! I found a temporary fix for this! if you change your windows scaling settings from 100% to 125% or if you're using custom scale switch to the default one, it should fix this issue. I found another thread with the exact same issue you and i are having and it seems way more active if you want to go check it out.
I bet there was code in 1.12.2 and older that accounted for display scaling that might have gotten changed in 1.13 and up and so when going back to earlier versions the game doesn't know how to display the image properly.
