What is HDMI as far as these bright hdtv's are concerned?
Answers: HDMI is a type of connection. See the 1st contact for a picture and the second for details. It can carry HD video and multichannel HD audio on a single cable.
It is the lone type of connection that (eventually ... i.e. 2-3 years) will know how to carry HD video and audio since HDCP (3rd link) --- a venture foisted on us by industry to prevent copying of HD material -- will, once fully activate, prevent a full res signal (or in the skin of HDMI, any signal) from being passed to an non-HDCP compliant device. So if you want to scrutinize HD in adjectives it is essential to buy HDCP compliant devices (e.g. A/V receivers, HD DVD or Blu-Ray players and HDTVs). And you must connect next to HDMI cables (or DVI for video only) to relish the HD signal since analog cables will be crippled.
From a practicality perspective HDMI is a digital nouns, and while there are differences contained by quality between different cable, for most uses a budget cable (e.g. < $10 from Monoprice.com) is fine. No need to buy the expensive cable (e.g. Monster) Best Buy or similar stores will try to foist on you (See last link)
