I am trying to play games from my laptop on my Bravia without having to connect HDMI every time.  I tried the SteamLink App but the picture cuts out briefly every 10 seconds or so.  I tried connecting using the Wifi Direct function without success, and although the advice from Sony is to use the screen mirroring App, I can't find any such App on my TV.  The TV is connected to my home network via ethernet.  My laptop can 'see' the TV as a device but can't connect.  I have connected my laptop via the Wifi Direct Wifi network but still no successful connection.  Any suggestions?
