Okay techies I need some quick help. I'm looking to purchase a 37" Vizio LCD (from WalMart or Sams) for my employer. We're wanting to be able to hook it up to one of our computers to use as a video screen. As you know most of these new LCD's have 2 HDMI ports as well as the old S-video port and RCA outputs. Our newer computers don't have an S video or HDMI connection but do have several USB ports. My question is what do I need to make this setup possible. My first thought was an HDMI to USB cable but I can't seem to find one online. Help!!!!!!
