1080p supports more then double the pixels of 720p. That is why there is such a price difference between the two. You get what you pay for. Are you saying that you should buy a 720p TV and move further away from the TV to minimize the discrepancies the human eye can see? I have a problem buying anything for this much money and knowing off the bat that I am purchasing something sub-standard.
I used the formulas and came up with 37-42 inches.
This is like buying a 302 HCI package... yeah you can get an e-cam and throw it into an explorer motor but why not get an FTI grind, AFR heads, and an Eddie RPM II manifold? I know that I'll never buy another 42 inch TV for a very long time because I bought top shelf and didn't compromise. And as all the networks and channels start to move toward HD broadcasts, I highly doubt they will be using a 720p standard.
That article you posted is somewhat foolish in that all of the conclusions sound like "probably" and "most likely" and "for most of us." It didn't convince me of anything. I'll take the facts please.
Cable type and length affect the information being passed along it. There are several different kinds of fiber optic cable. The 107 turbine windfarm I am designing in Michigan uses two kinds depending on what type of info needs to go from A to B. Cable is not just cable.
I suggest anyone thinking of this purchase read consumer reports.
