    HDTV "Sweet Spot" Chart

    Hey fellaz,i'm puttin this chart up so you can experience...if ya haven't experienced this already, but there's a viewing distance "sweet spot" where the extra detail in 1080p is much more apparent.

      so, for my 1080i CRT HDTV, this is suggesting I need to be sitting less than 5 feet away? That's really close and awkward. I current sit about 8 - 10 feet away on the couch. Our living room is pretty small, so there really isn't any other option. I'd have to move the couch or the TV to the middle of the room to sit only 4ft or so from the TV. That seems way too close.

          Now, with that HP I just bought, should I look at the 720 because it's a 720 or should I look at the 1080 because it can take a 1080 signal? It's a 32" btw.

              Why is the 1080i and 1080p on the same line? Is there no visable difference between these two?

              Anyhow, I got the perfect set up - I'm sitting about 10 feet away from my 46" 720p TV. I guess I don't need that 1080p after all.

                  My bold-printed, big-lettered breaker above is a little sensationalistic, but, as far as movies are concerned, this is basically true. Here's why. Movies (and most TV shows) are shot at 24 frames per second (either on film or on 24-frame-per-second HD cameras). Every TV sold in the United States has a refresh rate of 60 hertz. This means that the screen refreshes 60 times per second. In order to display 24-frame-per-second content on a display that essentially shows 60 frames per second, you need to make up or create new frames. This is accomplished by a method called 3:2 pulldown (or, more accurately, 2:3 pulldown). It doubles the first frame of film, triples the second frame, doubles the third frame, and so on, creating a 2-3-2-3-2-3 sequence. (Check out Figure 1 for a more colorful depiction.) So, the new frames don't have new information; they are just duplicates of the original film frames. This process converts 24-frame-per-second film to be displayed on a 60-Hz display.
