What You Should Know About HDMI Cables
To help you learn what to purchase and why, let us briefly discuss HDTV resolutions and their meanings.
HDTV Resolutions:
- 480i (480 interlaced lines of resolution) Also known as what you've watched on normal TV for years
- 480p (480 Progressive lines of resolution) Known as SDTV, progressively scanning images from a DVD player creates a nicer, smoother image on your SDTV/HDTV
- 720p (720 Progressive lines of Resolution) this is your initial step into HDTV. Allowing for 720 lines of resolution, nearly twice that of 480p, provides a much smoother image on a High Definition TV
- 1080i (1080 interlaced lines of Resolution) currently the greatest resolution provided by Satellite and Cable operators, offering exceptional quality picture on a television capable of displaying 1080i
- 1080p (1080 Progressive lines of Resolution) Also known as Full HD, 1080p is currently "IT" in the market place in terms of best quality picture.
Now that you understand the progression of HDTV Resolutions, let's figure out what all those numbers really mean on that new HDTV you've just purchased.
When you are selecting the cables to connect your HDMI equipped devices, these are some elements to keep in mind.
As you will be spending a superior bit on the cable, make sure you get one which is future proofed - even though your TV programs aren't broadcast in 1080p, the latest DVD and game consoles are, so get a cable that is 1080p certified. To make sure that it transmits video on top of lossless audio, make sure the cable is HDMI 1.3. Many cables longer than 10 feet begin to lose quality, so make sure that the cable is certified for 1080p. Lastly, pay attention to how strained the cable is, because most versions don't have any sort of locking device, and it can wiggle loose.
