A certified high speed cable is all you need. The problem is finding one that is really certified. Trying to do it on eBay is hopeless unless you are buying a known brand (and it isn't counterfeit). Buy from a reliable source, like monoprice, Blue Jeans Cable, or AV Science, and you will be safe. They all have 15' certified high speed HDMI cables that will handle any signal currently supported by the HDMI specification.
