Again, misconception and marketing hype. The only display type for which the
distinction between 1080i and 1080p matters is a CRT one (the good ol'
cathode tube, or a CRT projector).

You should be clear on what frame rate you mean. 1080p/24 or 60(50)
Hz?

Every other display out there (DLP, LCD,
Plasma) is putting out a progressive signal and performing de-interlacing
automatically anyway.

If you mean that from 24Hz material it is quite possible to transfer
the information in interlaced format with the double field rate, I
agree.

When de-interlacing video from an interlaced source, you don't need
much motion until the attempted de-interlacing gives artefacts and
reduced image quality.

Seeing as there are no traditional CRT televisions above 40", and only a
limited number of CRT projectors (which are quickly becoming obsolete) with
large screen sizes, 1080i vs 1080p is a moot point. From a de-interlacing
point of view, 1080i from XBOX displayed on a progressive-scan panel (DLP,
LCD, Plasma) will not strain your eyes more, or look inferior in any way to
the same signal coming to the TV natively in 1080p from a PS3, _IF_ the TV
itself has a native resolution of 1080 lines.

Now if you compare 1080p vs 720p (most of the flat panel displays on the
market right now are 720p ), surely there'll be a difference because of the
extra resolution, although it may actually look worse on an 1080p display if
the source material has a resolution of 720p!

The most common flat panels use 768 lines. Only a few of them displays
720p over 720 lines, leaving 48 black lines. The rest zoom the picture
to cover the screen (plus somewhat overscan). The point being that
most of them scale also a 720p signal. It is howver, less problamatic
to scale a progressive signal than an interlaced.

For gaming purposes, frame rates and having a TV set whose native resolution
matches exactly that of the game(s) you're playing (so that the TV does not
need to upconvert/downconvert the signal - which can degrade the quality and
introduce processing delays), are much more important than 1080i vs 1080p.
Wake up people.

I agree that matching the signal is important. So when when 1080p/50
or 60Hz original material is transmitted in that signal format it will
be an advantage to skip the reduction to 1080i or 720p provided that
the screen can make justice to the high resolution. 720p might
otherwice be a better choice in order to maintain the frame rate.
