This worked a few weeks ago, but, like a fool, I do not recall how I managed to get full screen mode to take up the full screen.

I have Optifine 1.12 installed, but disabling Optifine doesn't fix this. Pressing F11 to enter full screen with 'Fullscreen' set to 'On' or 'Off'.

Disabling high DPI optimizations for javaw.exe.

Disabling Optifine and repeating the above.

Setting a resolution of 1920x1080 in the 'Full Screen Mode' setting in the Video Settings menu.

Toggling 'Fullscreen' in the Video Settings.

I set the resolution to 1920 x 1080 in the launch options, but the window is still 1024 x 768 or something - I have no idea what I'm doing wrong. Pressing F11 enters 'full screen mode' but this only occupies a subset of the window. My display is set to 1920 x 1080, and the game was able to run full screen a while ago, but, I forget what the workaround was - any ideas? I haven't updated my graphics drivers in ages, so, it wasn't a driver update that broke things. Does anyone know how to make Minecraft run in full screen mode?
