A Class 101 Question. What is the difference between sets that
advertise: True 1080P HDTV and simply 1080P HDTV?

Found a SONY 46" LCD whose spec reads 1080P(double scan) which
says to me that its MAX source is something less than 1080P.

True 1080P says to me that it will accommodate a non-interlaced
1080 source (1080P). Period. (Plus, of course, other lower
resolution sources for up-converting).

Or maybe point me to a paper which clarifies these points.

Thank You

Whichever marketing *** started using the 'true' word was just
trying to juice up his crap to appear better than the other
marketing dicks stuff. 1080P = 1080P. Full. Stop.
Could it be that some sets will only accept up to a 1080i input, but
will upscale it to 1080p?
I've not looked at each and every HDTV out there, but of those I have
seen, I've not seen one that wouldn't accept just about anything
tossed at it, and displaying the source in it's native format. I've
got a small HD display in another room, and it feeds on a constant
diet of 1080I/P material every day, always producing a lovely image
in it's native 720P format.

And while I do consider progressive is better that interlaced, I don't
consider that improvement to be upscaled given the same number of
lines between the source and screen.

I have a set (DLP) that takes up to 1080i native input and scales it to 1080p, which is the case of some of the models made about 3 years ago.

Even now, most any 1080p input is from a 1080i source that is scaled to progressive scan.



Sounds like we're just dancing around semantics here. To me, 'scaling' is actually changing the number of displayable lines between the source and destination. To me, simply rearranging those lines from every other one (Interlaced) to all lines in sequence (Progressive) certainly improves watchability on a low-res display, much less so on a hi-res display.
