After sporting component video cables on our HDTV for more than a year, we've seen the clear, crisp light and made the move to an HDMI setup. Ok, the switch was made for us by the Comcast guy when he hooked us up with one on his last visit. But seriously, the picture's great. Grab an HDMI cable next time you head to the stores, but beware of overpriced versions. Experts say there's no reason to pay an inflated price.
Back before the world went digital, there were ways for manufacturers to improve the signal coming through analog cables. A "better" cord might have gold-plated connectors or be shielded from EM and RF interference.
But the signal working it's way through your HDMI cable is 100 percent digital. The cable either works, or it doesn't, and no amount of gold is going to make it work better, as you'll learn from this handy infographic over at the Mint.com blog.
What does downgrade the quality of an HDMI cable's digital picture? The length of the cable. When buying, go for the shortest length that your theater needs to ensure a strong image (a 6-foot cable is perfect for almost any setup), and don't pay more than $10.
