Question Mirroring to smart TV from windows 10 times out after 5 minutes

[Diltoid24]

Can't get really more detailed than that.. Every time I mirror my desktop to my smart tv, it times out after 5 minutes. I'm not using wifi, both TV and computer are wired to my router via ethernet. TV is a Samsung series 6 70"

How to you "Mirror"? What OS you're using?
