Guys, I know that you're kidding, but of course the bottom line of those articles is that with a given HD set you have to sit closer when you're playing 720 or 1080 material than you'd need when playing 480 material, in order to be able to see the full resolution. You don't move back when playing 480 on the set, you just don't get the HD resolution at the same distance.

Still trying to understand all this, John. When you feed a 480 signal or, for that matter, a 1080 signal to a 720p HDTV, isn't the signal converted (scaled?), by the TV, to the TV's native resolution (i.e., in this example, 720p)? Actually, we're joking (sorta) about needing seating with wheels or rails because the two articles disagree about the optimal seating distance for a given set of any resolution. That's why I said: Quote:
...if you compare the formula in the article Nick provided to the formula in the article I provided, for a 56"/1080p set, one recommends a viewing distance of 7.2', and the other 11.43'.
HOWEVER! I must stand corrected (while remaining seated). The formula in my article was meant only for 720p sets not 1080p. With that in mind, for a 720p set, the formula in my article recommends a seating distance of 11.43' and the formula in Nick's article recommends 10.8', which is only a difference of about 8.5 inches. So, actually, the formulas don't disagree to any significant degree. Apologies to all.

So we only need short rails then ?
Whew, that's a relief.

Yeah Jack, those two rules-of-thumb are in close agreement on your 56/720 example, and also with the S&V graph, which shows about 11'. On your first point, note that it's the "real" resolution of the program material, which isn't increased by upscaling, which limits the observable resolution. For example, the S&V article states in discussing an example(beneath the first graph): "...so a high-def program on a 720p HDTV-or a 720p program viewed on a 1080i or 1080p HDTV...", indicating that the 720 program material is the controlling factor with regard to resolution on the 1080 set.

Yeah, I vaguely had the concept that 480 or 1080 material converted to 720p wouldn't quite look the same as 720p material on a native 720p set. Somthing is lost in translation, I guess (filling in pixels; removing pixels?).
