Q: I’d like to purchase an HDMI cable for my new HDTV, but the 6-foot cables at the electronics store are $50 each. I’ve found some cheaper cables online for only about $10. Is there any advantage to paying for the more expensive cable?
A: An HDMI (High-Definition Multimedia Interface) cable is a type of digital connection that can transmit high-definition video and high-resolution audio over a single cable, rather than using a bundle of analog and component-video cables. Regardless of what the salesman at the electronics store may tell you, there is no significant difference between the $10 cable and the $50 version. The digital information transmitted by both cables is exactly the same, and no HDMI cable will make the picture any better or worse than another HDMI cable.
