Wire Free Life

So, if I wanted to make changed with our cable... would I need to use something like an HDMI splitter? My husband and father in law were talking about splitters and cables and what not over the weekend and it all sounded like Greek to me! You know how on Charlie Brown all the adult voices sounded like "wah, wah, wah, wah?" Well, that's how I felt like they were talking when they started in on that! I mean I get confused just looking at the cables behind the TV... and thinking about hooking up a computer or anything technical like that makes me cringe. It makes me so super thankful for the husband I have... I don't have to fool with stuff like that!
