I am having a problem understanding your "1/2 to 1/3 viewing distance"
Follow Ups:
The best formula for viewing distance for a high scan and hd projection sets are 2x the diagonal dimension. This is because the internal line doublers/quadruplers create finer scanlines on ntsc signals, and virtually nonexistent scanlines on hd broadcasts.i.e. 61" set, ideal distance is 61"x2=122" or about 10 feet. From
my personal experience, minimum is 9' to about 11' max
53" set, 53x2=106" or about 8.8 feet +/- 1'
The idea is that the DTV resolution is good enough to give you relative screen size perspective comparable to movie theatre screens. For example, on a (small) 30" widescreen set, the actual dimensions of the screen are about 26" x 15". Multiplying the vertical dimensions by factor of 3, you get 45" or about 4 feet. So, the optimum viewing distance for a 30" widescreen is about 4 feet. Now, that seemed too closely to me at first, but after trying it out myself, I became convinced that it actually works. So, for a person viewing the TV from 10' away, the larger RPT unit is probably a better choice.
