How to go fullscreen in PowerShell

Is there a way of making powershell appear in fullscreen? Not only maximize it over the screen, but hiding the top-bar as well?

Also, since this is probably hard to do, how to maximize it according to current resolution?

Try typing the following command:

mode 300

after the window opens

Right click the top bar and select properties. Then depending on your screen resolution select the appropriate size. (under the layout tab).

ALT + ENTER will full screen the powershell window in Windows 10

If this doesn't work right click the title bar > properties > options and make sure "Use Legacy console" is unchecked:
