The game does support only 16:9 resolutions. But using 16:9 resolution, the game cuts interface, It seems the game is designed for 16:10, but 16:10 is not supported by the game, only 16:9.
If you use fullscreen, which is pretty unconfortable for this kind of game, where you are most time afk, you can use the monitor resolution, whatever it is.
Also the game does not support windows fullscreen.
If you use 16:9 resolution, the games does not fit into the screen, but 16:10 is not supported by the game in window mode.
