Here's a short snip:
Almost everyone has heard the term “HD” these days, even if they don’t know exactly what it means. The marketing definition is “better looking TV,” and while that’s good enough for most people, actually getting that “better looking TV” can be difficult and quite expensive. Every related product has taken advantage of those two letters. Advertisers have even used it to refer to mundane products such as window cleaners (“for a high definition shine!”). It can be a confusing technology for those just looking to purchase their first HDTV unit, but for those looking to enter the world of High Definition through their PCs, it can be even more complicated.
