How do i run minecraft on my second screen. I have laptop w/ monitor connected. Minecraft doesn't want to play on second monitor. Please?

Press Win key-P and select the screen that you want.

Please reread the graphic requirements for minecraft. Does your second monitor meet them? Does your laptop?

Most full screen programs default to whatever screen is set to be the main screen by Windows.

Your options are basically run Minecraft in Windowed mode so you can move it between screens, or change the default screen in the display settings.

Make the monitor the "primary screen" in the display settings of whatever operating system is running that laptop. Minecraft may run on that one.

Spawn so many mobs
