It was an iffy system and might be on the outs.
I have upgraded my win 7 to win 10 and I am trying to miracast to my smart tv but to no avail.
in dxdiag I received the following message - Miracast: Not Supported by Graphics driver
However, I can cast a single MP4 and youtube to my smart TV.
I am using an old AMD Radeon HD 6700 Series. If I will upgrade my card it will help or I will have to buy a dongle.
Any thoughts will be highly appropriate.
