Why is my Lumia 830 losing the display when screen sharing HD-10?

[Windows Central Question]

Lumia 830 and microsoft screen sharing HD-10

I can connect. I can play video on TV. BUT after about 5 to 10 mins it simply drops connection, loses video display on TV. then repeats trying to reconnect.

I have disabled the screen lock so it should not cut off from the phone.

does anyone have any ideas.
