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.




That 'double scan' business is a reference to the scan rate, ie.
60Hz or 120Hz - an optional viewing feature in the setup menu.
