Hi @Robert1872, let me see if I can help you out.
I have translated your question to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.
How are you trying to connect to your TV? Screen mirroring trough Miracast directly to your TV? Or are you doing it by for example a Chromecast?
Are you getting any error messages at any point?
Give me more information regarding this and i will do my best to help you out!
