Suppose I have 3 monitors but 2 are in another room. I want to be able to see and interact with what is on the other two from only the main monitor (to move window around). Any way to accomplish that? On a Windows environment. No Internet Access and no network access. And no hardware modification, only software allowed.
Hold Shift, press and hold the Window key, and press right or left arrow. The window will switch monitors. Interact with it as you wish then send it back.
