Expensive cables aren't worth it
If you walk into your typical electronics store to buy an HDMI cable, you're likely to see prices upward of $50 with promises of better performance and faster speeds. Do you really need to spend that much money on a single HDMI cable?
Absolutely not--those cables are a rip-off. You should never pay more than $10 for a standard six-foot HDMI cable. And despite what salesmen and manufacturers might tell you, there's no meaningful difference between the $10 cable and the $50 cable. Unless you see something obvious, such as dropouts or a flashing screen, the digital information transmitted by both cables is exactly the same--no cable can make the picture any better or any worse. We've used cables from many different companies in the past--such as Belkin, Accell, Monoprice, Monster, and SimplayHD--and have not run into any consistent issues with any brand of cable. With working cables and solid connections, we've seen no dropouts and "sparklies"--just consistent, dependable, high-quality audio and video. It's that simple.
Even a heavy-duty, high-end Monoprice cable cost us less than $20. But feel free to buy a cheaper one for a standard home theater.
