I have a laptop and I want to play minecraft in full screen on my extra screen, but when I open minecraft it appears on the laptop.
My OS is Windows10
Press F11 to bring Minecraft from full screen mode to window mode.
Move window to second screen.
Press F11 again and reactivate full screen.
You place your mouse at the top of the window and drag the window to the 2nd screen.
Otherwise, you can also use the second screen as the main screen, or have it set.
OK thanks
Thank you
