The fact remains that on a 40-42 inch diagonal display you do not need 720P to produce sharp images. Hook up a standard definition DVD to one display and a Blu-Ray DVD player to an identical display. position the viewers at about 7-9 feet from the display, and 9 out of 10 people will not be able to tell the difference between the two.


Visit <http://www.carltonbale.com>www.carltonbale.com and read the posting titled "1080p Does Matter" for another viewpoint.

This chart is very misleading. It is off by a significant factor - probably by a factor of two at the closer in viewing distances

It suggests that 720P starts to become noticeable at a screen size of about 25 inch. This is absurd. It suggest much the same for 1080P, starting to become visible on a 32" screen. This may actually be true if you sit 18-30 inches away as with a computer display, but not a five feet as the chart suggests.

More important is the fact that people will not choose to sit at the viewing distances suggested. The CLOSEST that most people would sit to a 60 inch screen is about 10 feet, so everything inside that distance is meaningless.


So do you agree or disagree with these statements from the article:

"What the chart shows is that, for a 50-inch screen, the benefits of 720p vs. 480p start to become apparent at viewing distances closer than 14.6 feet and become fully apparent at 9.8 feet. For the same screen size, the benefits of 1080p vs. 720p start to become apparent when closer than 9.8 feet and become full apparent at 6.5 feet. In my opinion, 6.5 feet is closer than most people will sit to their 50" plasma TV (even through the THX recommended viewing distance for a 50" screen is 5.6 ft). So, most consumers will not be able to see the full benefit of their 1080p TV."

I believe if people are trying to emulate a theater experience at home, they will sit closer (THX recommendations) or get larger screens.
