Q. I just bought a new HDTV and everyone tells me I will get a better picture if I use an HDMI cable instead of my old component cables. So, Mr. Answer Man, what kind of HDMI cable should I get and how much should it cost? — Toni, Dayton, Ohio.

Toni, first of all, you are right. An HDMI cable will give you a better HD picture and better sound than Component cables. I won’t say the improvement is dramatic, but it’s noticeable. Plus, the HDMI cable is a more efficient connection; it has just one prong compared to the multiple-prong Component cable set. Plug one end into the HDMI In port of your TV and the other in your cable or satellite box’s HDMI Out port and you’re all set.

So how much should you spend on an HDMI cable?

In the early days of High-Definition TV — and even now in some quarters — store salesmen would swear on a Bible that you needed an HDMI cable that would cost anywhere from $50 to $100. They said that anything cheaper than that would result in a inferior picture.

Well, that was nonsense then and it’s nonsense now. There’s nothing wrong with those expensive HDMI cables — you can even make an argument that some are more sturdy. But they won’t give you a better picture than a solid, name-brand sub-$10 HDMI cable.

And if the less expensive HDMI cable doesn’t last as long as that $99 HDMI cable, big deal. You can just go out and buy another sub-$10 HDMI cable to replace your old one.
