I have a surface book, Mini DisplayPort to HDMI adapter, and a HDMI cable. Yesterday I was able to connect my pc to my TV, but now all of a sudden I can’t. I tried it with my old MacBook Pro 13 and no issues, but now with my surfacebook it doesn’t even detect it. The cables haven’t moved from yesterday so I don’t know what’s wrong. Please help me I need a solution, as my Macbook isnt good and wont last long and I want to mirror my movies to my TV.
