HDMI survival guide for home theater

By | March 20, 2008, 10:59pm PDT

There’s a lot of money to be made in the HDMI cabling and switch aftermarket and unfortunately that means a lot of consumers are getting tricked in to paying outrageous prices.  I’ve spent quite a bit of time helping my friends set up their home theaters recently and I thought I’d share that knowledge with my readers.  If you’re tired of paying high hundreds of dollars for HDMI switches and HDMI cables, read on.

What is HDMI?
HDMI is a high speed digital interface for the transmission of high quality digital audio and digital video.  So if you plug your DVD player, your PlayStation 3, your satellite or cable TV box, or even your computer up to a modern HDTV with a single HDMI cable, then the sound and picture will all work.  The HDMI plug only has a single small connector so it’s nice and simple.  Before HDMI, you had to hook up three separate connectors for just the video and two additional RCA plugs for stereo sound.  Instead of the two RCA plugs, you could also use an S/PDIF optical cable for the sound but it still adds a lot of cable complexity and clutter compared to a single HDMI cable.

Why are there different HDMI types?
There are 4 basic versions of HDMI.  You have 1.0, 1.1, 1.2, and 1.3 and you can get a quick summary of the capability of each version here.  The easy answer is the higher the number, the better.  If you’re shopping now, try to stick with the HDMI 1.3 devices if you can.

Do I need monster HDMI cables?
No, HDMI monster cables are simply a monster rip-off.  If a cable is HDMI certified, it will by definition offer you a perfect digital signal.  Despite the fact that the electrical signals traversing an HDMI cable degrade as a cable gets longer, it will still offer perfect digital transmission so long as the signal loss or distortion is within a certain tolerance.  Analog cables might benefit from extra thickness and insulation because there’s not much you can do to fix analog signal loss or distortion other than to amplify and maybe filter the signal a little to mitigate the bad side effects.  But when it comes to digital technology, the signal is either all there or it isn’t.  There is zero measurable difference in the digital signal quality between the $6 HDMI cable and the $60 monster HDMI cable.

Where do I buy cheap HDMI cables?
There are lots of online vendors that can be found via a quick Google search of “HDMI 1.3 cable”.  These cables suppliers have always been reliable in my experience and they’re many times cheaper than the local retailer.  Here’s a few examples I compiled.

  • Bless you my son.....
    Excellent article George!

    It's about time someone in the media started talking about the monster rip-off cables. I love the fiber optic cable scam as well. Why pay $60.00 for a 3 meter cable when the GE cable is only $8.00 in the same store? Do you think General Electric can?t be trusted to make a simple cable?


    If it is HDMI 1.3 certified (It will have the HDMI logo), then you are good to go. Have any questions about that, see the HDMI website at http://www.hdmi.com .

    Yeah it's a big scam. I've talked before about it but not dedicated an entire article to it before. Hopefully this will help a lot of people.

  • Thanks
    I was treated to a lecture by a Best Buy employee who was
    telling all about millisecond 'signal response time'
    differences and soldered vs crimped connections, all the
    while holding up a 6' $100 Monster cable.

    I listened politely because the kid seemed to truly believe
    what he saying, then said, "no thanks, show me cheapest
    hdmi cable." Turns out Best Buy doesn't see an hdmi cable
    under $60. I ended up getting one at HomeDepot for
    about $30. Still too expensive, but running around
    shopping gets expensive as well.

    All HDTV accessories are outrageously overpriced! Thanks
    for putting the truth out there. Gold plating, soldered
    connectors, thick insulation, slick packaging and racing
    stripes mean squat on a 6' hdmi cable.

    Yeah they don't like to carry the cheaper cables or the switch boxes. That's why it pays to be prepared and just order all the cables you need online. If you wait till last minute and you buy a $1000 HDTV and you're dying to try it out, you might just be inclined to buy that $60 HDMI cable just so you don't need to wait.

  • actually they do...
    You see George-- they DO carry the cheap cables and switches-- they just mark them up SO FRIGGIN' MUCH because they can.

    Once demand drops, prices will too. They just inflate b/c like you said-- customers are hot and bothered at the spot.

  • almost
    Gold plating does make a difference. Gold doesn't oxidize, so in the long run you get a better connection with it than without it. All the other stuff that you get charge big bucks for will usually not make a difference unless you plug and unplug the cables often.

  • Woooow Dude
    Len hit Fry's if you have one. We just bought a Samsung 40" HDTV 1080 (Love the Red framing edge) from best buy then found the same TV lower at Fry's. Called Best buy told them we were bringing it back. They refunded us the difference Plus 10% and at close to $1500 I am happy with the refund. We also got the HDMI certified cable's at a fraction of the price that they were offered at best buy. Plus we bought a Samsung Blue Rey DVD player that was the same model at they carried at best buy but more than $80.00 bucks cheaper... It pays to shop around. We have Dish HD and the picture quality on the TV is actually better than it looked in Best buy

  • Whatever happened to UHV TV?
    Used to be, you could go to your TV and select UHV and turn a knob like you were cracking a safe and bring in those 'fuzzy' stations.

    What happened?

    That is where the digital channels are placed.

    We still got them, but it's blocky when the signal is bad or insufficient. It's called ATSC happy.

  • old tech.
    You must mean UHF and VHF. That just refered to where on the spectrum the channels were. The feature you describe, tuning in the channel with a dial, was available on both frequency ranges. That was fairly old technology before they came out with the self adjusting circuits that would tune in the channel to the strongest signal all by itself. So the dials were no longer needed.
