Someone recently gave me a Polaroid HD LCD TV (2010). I didn't know what to do with it so I decided to use it as a second monitor for my PC. I went out and bought an HDMI cable and just assumed it would connect right away. I'm using WIN7 (don't make fun.. I like it.) But no matter what I do, I can't seem to figure out why it won't connect. I can usually figure out computer-type things but I'm stumped.
