u know if we use HDMI in function in XBONE, and if we get TV app in it we get what ever on the other si,de of the HDMI. i use my PC GPU hdmi out to xbone but cant get a screen. why? must do some stuff before ? my pc screen keeps black outs like it keeps detecting a new screen.. final moment update: i got the visual on TV now. which is connected to XBONE. this is a new tv. only has TWO HDMI INs . yeah lame but 2015 LG soemthing 4K great. anyway. but screen on TV now is extended. i pressed windows + P keys. and made it duplicate. but now tv screen is gone again.
