Casting from PC to TV

I had been unable to cast photo’s from my PC to my TV until I disabled Avast. Would like to keep Avast enabled and just turn off the feature causing the block. Would anyone know what that feature might be? Thanks.

Whilst I don’t use Cast feature on my phone.

The most likely interaction (my opinion) would be the connection between the PC and TV isn’t Private but Public and not trusted.

Check the Avast Firewall and Network Inspector functions.

Will look at that this weekend, thanks!
