Pre listen, screen mirror, vsts standalone

Hi, any way to pre listen the sounds on the headphones as you play on performance mode, like to edit on the go without playing the sounds you making or arranging through the main out?

About mirror the screen to a screen monitor.. if the force/mpc, mirros the pc why we cant mirror the force screen to a monitor? I even mirror my phone with wi fi to my tv or with an app to the pc.

Vst's any news about lauching vst's feom ssd maybe? The processor and memory are good enough. Even if a limited amount per track and even of a certain choosen ones more than just the ones present. Any news about this?

Thanks
