Is it possible to transfer / mirror YouTube videos from a smartphone to a TV that has NO internet with a cable like the one in the link, or does the TV have to have internet for this?
It's all about watching the videos on a bigger screen, I don't really want internet on TV.
Quote from customer question:
Can you connect your mobile phone to the television?
Answer: Definitely. I have the Samsung S8 and I haven't had any problems so far. Your mobile phone screen is then completely displayed on the TV, just like with the Smart View.
It depends on your smartphone. Not every device can mirror the screen via USB Type-C or output an image.
As a guideline, it can be said that all smartphones with a USB 3.1 port and Type-C connector support this function.
Which smartphone do you have?
However, you will get a better user experience with e.g. Achieve a Google Chromecast.
