Well there's a difference between "High Definition", a term used mostly to describe consoles and TVs, and "High Resolution", used mostly to describe video cards and computer monitors. With a computer monitor, you're (usually) sitting very close to the screen, where as movies and console games are enjoyed from a couch, bed etc. several meters from the screen. This means the requirements are completely different and you're comparing apples to oranges. I'ved used 1024x768 (nearly 720p) ever since the Voodoo3 nearly ten years ago. When I got the original Radeon 64MB a little later, I switched to 1152x864 (slightly faster than 12x10 and more natural aspect ratio) and then 12x10 when I got a 19" display in 2003. Noone called that "High Definition", because the term wasn't coined yet. We just said that the new cards allowed for "high resolution" gaming. High Definition is just a buzzword invented by the HDTV and gaming console industry because it's easier for people to understand the word "Definition" than "Resolution". "High Definition" on the PC has been around for over 10 years.
