I have a 2014 Samsung Smart TV UE40HU6900. I can successfully stream video content wirelessly via an app (Metro Media Player Pro) on my Microsoft Surface Pro 2 Tablet using Windows 8.1 so I do not think I have network problems.
My problem is with Screen Mirroring using Multicast in Win 8.1. It connects and runs fine for a short time (5-10 mins.) and then the TV disconnects.
My TV software and Windows software are all up to date.
Any ideas?
