Man, what an kettle of worms. (good OT topic, though)
In your doc, you mention a number of things which need further qualification.
LCD/LED technology is actually "older" than digital TV technology.
(as far as mass consumer devices)
Comparing LCD to a CRT is truely apples vs oranges. You either like apples
better or like oranges more.
I am a bit confused on your image comparison. (with the 4 different overlaying
screen sizes)
Here is how I came to determine that 16x9 was right for me:
A 27" 4x3 TV has ~729 sq inches of viewing. (for 4x3 material)
A 27" 4x3 TV has ~614 sq inches of viewing. (for 16x9 material) [~24" 16x9 TV]
A 30" 16x9 TV has ~900 sq inches of viewing. (for 16x9 material)
A 30" 16x9 TV has ~600 sq inches of viewing. (for 4x3 material) [~24" 4x3 TV]
But, remember, a 16x9 TV will expand the picture to take up the entire screen,
which significantly reduces the apparent loss of viewing. (at also makes a
celebrity's head appear proportional to their egos...hehe)
So, the point of all this wonderful math? Well, if you only watch 4x3 material,
well, you should stick to a 4x3 TV...for now. But, there is omre 16x9 material
coming out each day. Movie houses are moving away from dual aspect ratio
releases and are solidifying on "widescreen" only releases.
As far as cost, well, that is a different issue. Its the HDTV tuner and
progressive scan DVD player that is going to eat up a person's budget.
ALOT of home theater buffs have gone to either rear projection (RP) or front
projection (FP) setups. All the FP setups I have seen in recent months are
consumer grade (or prosumer grade) LCD or DLP "office projectors" that list at
under $2K. (some SDTV FP are selling for $1100!!!)
Folks are making their own 86" (16x9) screens for less than $60.
- 16x9 viewing is on a 7396 sq inch surface
- 4x3 viewing is on a 4900 sq inch surface (equivalent to a 70" 4x3 screen)
Here is what yours truely has wasted time/money/sweat/blood on:

Now, don't get me wrong...a FP (or RP for that matter) do not have the
brightness or contrast that a good CRT has...but, those are tradeoffs you live
with in order to get a really big screen. (and still save money vs. a plasma)
What does all this have to do with TS? Well, for my renderings, I am now
rendering everything in 1600x900 for final output. I can resize this down to
1280x720 and then go right to 720p HDTV signalling. I can resize/crop it down
to 848x480 for anamorphic widescreen DVDs, or crop it for use with 4x3 prints.
[NOTE: the whole 1080i vs 720p battle is way WAY too offtopic...email me
private to get a religious sermon from yours truely]
Hope everyone is confused now...<sinister laugh?
