while at work i plug in my Yoga S730 and use it as 3rd monitor. While at home I use it with Razer X Chroma (Red Devil rx580) and 3 4k monitors. 

how can i turn the internal screen off? even tho the laptop is closed, the internal screen keeps popping as the 4th screen (well screen #1 in this screen shot)...

cannot close inernal screen
