How to enable fullscreen?

I want to make it as fullscreen as possible but the game only covers a small portion of the screen.

The screen resolution is 1366x768 and I want it to fill up a bigger 16:9 screen. How do i do it without making it windows mode?

What do you mean with

Do you want to stretch the screen to cover it entirely? I think native games do it by default, and for web games the action to enable the fullscreen has an extra option to stretch (don’t keep aspect ratio) :slight_smile:
