HDMI cables are licensed under two specifications, standard and high-speed, everything else on the label is a bunch of hooey. If you have an HD TV that can support 1080p resolution, then you need the high speed in order to deliver the best quality picture from your blu-ray player. Ignore everything else on the package. Some stores, like Best Buy, have HDMI cables that talk about TV refresh rates on the package. They list specifics like 120hz, 240hz and 480hz. HDMI cables cannot effect your TV's refresh rate. That is handled entirely by the TV's circuitry. It's just a cheap marketing scam to get you to pay more.
Don't be fooled by labeling that says ultra-high speed either. High speed is high speed. Again under the licensing specs, any high speed cable can pass the 1080p and 3-D signal at optimum speed for the best picture. Some of these cables cost $150 to $250.
My suggestion is to by the one on Amazon for $3.99.
