HDMI cables – Things you need to know |
| Vic Metten |
So there you find yourself, standing in your local Retailer, taking in all of the awesomeness of High Definition amazingly displayed on 100 different Televisions in front of you. Truly, this can be confusing. You make your choice, buy it, and take it to its new home. You unwrap and plug in your device to get a picture that looks... nothing at all like it did at the retailer. So miracle of miracles, you get so upset you actually open the manual, where you see a reference to a connection for High Definition called HDMI (High-Definition Multimedia Interface), and you think to yourself: that's what I need.
You return to the local store, only to hear of DVD players that do upscale conversion, HD-DVD players, Blu-ray DVD players, Video Game Consoles, and a host of other items which use this new interface connection. You thought you understood your new HDTV, but new technological choices have you baffled.
HDMI cables are great for high definition since they allow both Audio and Visual to travel on the same cables, and HDMI cables transmit more bandwidth which allows higher resolution than Analog connection. HDMI is the necessary connection that you will require in order to display a Full HD picture on a Full HD capable television. Why fuss with multiple cables when one will do? HDMI combines digital audio and video in one convenient cable.
If we quickly review HDTV resolutions and their meanings, that should help with learning what to buy and why.
HDTV Resolutions:
* 480i, which refers to 480 interlaced lines of resolution - this is what you've been watching on normal TV for years.
* 480p, 480 progressive lines of resolution, or SDTV, refers to the technique of progressively scanning images from a DVD player to create a smoother image on your SDTV/HDTV.
* 720p, or 720 progressive lines of resolution, which is the first real step into HDTV.
* 1080i (1080 interlaced lines of Resolution), furnishes a better picture by allowing for 720 lines of resolution, almost twice that of 480p; giving a superior picture on televisions that can display 1080i.
* 1080p (1080 Progressive lines of Resolution), right now it is the most resolution provided by Satellite and Cable operators. For the finest picture, 1080p, best known as Full HD, is number one in the market place at this time.
After this tutorial about the progression of HDTV Resolutions, you'll finally be able to translate those mysterious numbers on your brand new HDTV.
When you're getting the cables you need to hook your HDMI-enabled devices together, these are things you must keep in mind.
The best cable to buy will be the future proofed 1080p certified variety, which, while not necessary for your TV, will work on the latest DVD players and game consoles. Only cables rated as HDMI 1.3 certified will carry video and lossless audio, so make sure your cable is certified at that level. Also, ensure that your cable is certified for 1080p if you use cables over 10 feet long, since many cables degrade once they reach that point. Periodically check the cable strain, because they can wiggle loose as most lack any locking devices.
That's all it takes! The only thing left to do now is get an HDMI cable. Then you can sit back, relax, and enjoy the crystal clear audio and video!
