My apologies, you did mention that in your original post. Did casting from the Chrome Browser work before or has it always had this symptom? Are you just casting over network or are you using a third party extension through the browser?
1. Casting worked before specifically from Chrome. This was never a symptom before and my casting works to other TVs.
2. I am just casting over the network. Ethernet goes to all my TVs.
3. No third part extensions are needed. I can stream to the TV with Windows 10 and it doesn't happen.
