Unable to mirror iMac to smart LG TV
I have repeatedly tried to connect my Intel processor iMac (Sonoma 14.2.1) to my LG Smart TV in order to watch international rugby matches from Europe and totally without success. So far none of the many articles I have come across have solved the problem. When I open the Control Centre and select Screen Mirroring it does not show my TV as I had assumed it would. Both the TV and the computer are on the same network. I had thought my VPN might be interfering and I have tried connecting with this switched both on and off. I have even tried a few commercial programs, such as Miracast and again without success.
I know there must be a solution to this and any help anyone can provide would be very gratefully appreciated.
iMac 27″, macOS 14.2
