(adsbygoogle = window.adsbygoogle || []).push({}); Today's high-definition home theaters run on digital audio and video, and HDMI™ is the connection of choice. That's because HDMI (High-Definition Multimedia Interface) delivers crystal-clear digital video and audio via a single cable, dramatically simplifying cabling and helping A/V fans enjoy the best possible home theater experience.

we'll explain what HDMI is and how it differs from conventional analog connections, and include some quick tips on choosing HDMI cables. You'll also learn what the exact differences are among the evolving versions of HDMI, and what kind of HDMI cables you need for 3D TV. And finally, we'll look at some real-world HDMI hookup issues along with solutions and workarounds.
HDMI: The "king" of high-quality connections

HDMI's pure-digital interface is the best way to connect high-resolution components — Blu-ray players, the PlayStation® 3 and Xbox 360™ game consoles, and HD-capable satellite and cable TV set-top boxes — to HDMI-equipped high-definition TVs and home theater receivers.
HDMI ouput HDMI is the connection of choice for high-definition, since it can carry full 1080p video, as well as multichannel audio. It's also the only way to get 3D video signals to your 3D TV.
Single-cable convenience, plus so much more

The ability to send high-definition video and multichannel audio over a single cable is unique to HDMI, but this interface offers other big advantages.

* Superb picture and sound quality: HDMI connections keep audio and video signals in the digital language of 1s and 0s, eliminating the compromised picture and sound quality caused by digital-to-analog conversions and reconversions. HDMI supports video resolutions up to 1080p, which is key for 1080p-capable HDTVs and Blu-ray players. (Although there are a few TVs that accept 1080p signals via component video, it's nearly impossible to find a high-def source that can supply 1080p over anything besides HDMI.) And HDMI's sound capability now supports up to 8 channels of super-high-quality 24-bit 192kHz audio.
* Ability to carry 3D video: HDMI is the only connection that can carry 3D video signals from components like a Blu-ray 3D™ player to your 3D TV.
* More than just audio and video: A standard HDMI connector has 19 pins, which carry not only audio and video data, but also 2-way control and identification information, and even low-voltage power. The most recent HDMI cables, labeled "1.4", can also provide an Internet connection between compatible devices.
* Industrial-strength copy protection: This probably seems like more of a benefit for content owners like movie studios than for consumers, but it directly affects the quantity and quality of what we can watch — now, and in the coming years. HDMI's wide adoption is due in large part to Hollywood's demands for ever-stronger copy protection measures to prevent piracy. HDCP (High-bandwidth Digital Content Protection) is present on virtually all HDMI-equipped devices even though it's not officially part of the HDMI spec. Without HDCP, both the quantity and quality of high-def content available to consumers would almost certainly be more limited than it is.

However, HDCP also has a downside. One of its main jobs is to "authenticate" the connection between two components via a "digital handshake," and problems with this handshake process can result in the loss or degradation of picture and sound.

Quick tips for choosing HDMI cables

Some components include an HDMI cable in the box, but most don't, so plan on buying one to connect your gear for the best picture and sound. You won't see dramatic differences in picture quality among HDMI cables. Unlike analog video transmission, which can display varying degrees of picture quality, digital video transmission typically delivers a clean, clear picture or no picture at all. But you'll still want to choose a high-quality HDMI cable, especially for longer lengths or in-wall installations. Different cables use different materials and construction techniques, and some are rated by the manufacturer to maintain maximum signal quality over longer cable lengths. Some users have encountered interoperability issues when making HDMI connections, but these are almost never the fault of the cable itself.


Choosing the Right HDMI Cable
1.
Step 1

Measure before you buy. It is crucial that you figure out how long your HDMI cable needs to be. So, use a tape measure and figure out the distance between your HDTV and whatever device you'll be hooking up to it. Write this distance down and remember to check and make sure that the HDMI cable you purchase is at least a few inches longer than your measurement.
2.
Step 2

Don't be a conspicuous consumer. Just because an HDMI cable is more expensive doesn't mean that it's better. In fact, all HDMI cables are essentially the same exact product. So, don't pay more for the same product because you assume that the higher price tag comes with a higher quality. If you do, you'll just end up paying for a brand name that won't have any impact on your picture quality whatsoever.
3.
Step 3

Shop online. Even warehouse stores like Circuit City or Best Buy only keep higher-priced HDMI cables in stock because those cables make them more money. Try shopping online instead in order to find the best possible deal. Even if you have to pay shipping and handling, it'll still likely be cheaper than shopping in the store.
4.
Step 4

Check your components before you make the purchase. Although HDMI cable isn't really a big-ticket kind of purchase, it can be relatively expensive compared to other cords and cables of a similar function. So, before you buy HDMI cable, make absolutely sure that both your TV and your peripheral are HDMI compatible.

Tips & Warnings

*
If you buy online, make sure you get the right kind of connection. Most home consumers need the basic male-male HDMI cable configuration, wherein the cable has two male ends. Make sure you don't end up buying the wrong type of configuration by accident.
*
Remember, don't overpay! There's no reason to pay $100 for an HDMI cable that's really worth $10. Do your research and make sure that you aren't being taken advantage of.

Wow nice post.
