In mine too given a good quality display...

OK - So lets take your stance then ... why should the world settle for
just 1080 if there's a 1125 line format available?

Strange that you see a parallel between those two examples but there you
go.

PC screen resolution is a matter of personal preference ... I tend to like
higher resolutions (I use 1920 x 1200 on my laptop, 1560 x 1024 on my home
destop and 1024 x 768 on the 15" LCD I have on my desk at work) but
one
person here has a 17" 1280 x 1024 LCD that they run at 800 x 600 -
that's
her preference.

Strangly for broadcasting to an *AUDIENCE* we need standards that
everyone's receivers can adhere to as a minimum spec.

Taking your PC example as a point of reference, what would happen if you
tried to display the same 1280 x 1024 image on everyones monitors at the
same time - those people with monitors only capable of 1024 x 768 wouldn't
see anything. So to try to make sure that everyone gets to see something
they come up with these things called standards and the *STANDARD* they
have reached for high definition broadcasting in Europe says that anything
that can handle either 720 or 1080 lines fits within the standard as
"high
definition".

Now, if you had said "I prefer 1080 to 720 and I think it would have
been
better going that route" then I would not have disagreed with you but
you
simply made the statement that the world should go 1080.

You are the one making pointless statements which are simply your opinions
dressed up and spouted out as facts.

Ahhh ... so you're now making the jump to film from your broadcast spec TV
cameras?

Good - so were a number of other people. Honest.

I'm sure the world mourns the fact that you are unhappy ...

...however the *FACT* remains that your original *STATEMENT* that 720p
isn't high definition is *INCORRECT*. If you feel that this is in error
then please provide me with the appropriate information or URLs to show me
that 720 lines has been removed from the European standard for high
definition broadcasting.

720p and 1080i are both perfectly valid formats in the European high
definition standard and therefore any display capable of displaying
*EITHER* 720p or 1080i at are high definition *CAPABLE* as laid down by
the latest agreed European standard. Similarly any display able to accept
a 720p or 1080i source and downscale it to its own native resolution (e.g.
a plasma display with 480 resolution) is - although unable to display at
native resolution - high definition *COMPATIBLE*.
