Novice mac experience so please help! In terms I can hopefully understand I need to connect my old Mac mini to my dell monitor. Info below on what I'm working with. I have to order a power cord for the monitor and I think I have chosen the correct one. I'm robbing my Apple TV of the power cord for the Mac mini (hope this is ok since it fits) (I know, I'm a nightmare) anyway I need to understand if I have wifi capability from the mini to the monitor or if I need to have a physical cable to connect them, my guess is yes. But I'm not sure what kind of USB I need to purchase to connect these two. Any assistance is welcome! Thank you!!!
