I alway thought full 1080p meant 1920x1080. Tv's at Best buy that are Full 1080p have native res of 1920x1080. I bought a few days ago a Samsung LN32B550. It has a native res of 1920x1080.

I'm sorry I was under the impression Blu-ray was Full HD like the TV's that are advertised say Full HD 1080p. So let me get his right the movies might be full 1080p vertically but horizontal it's lower that than 1920 more like around 1280 from what I'm seeing.

I'm not really sure what you mean. Are you talking about letterboxed movies?
Yes, the VAST majority of movies are encoded at 1080p, ie, 1920x1080.

Your off topic. Yet another person not reading the full topic.
Did read anywhere in my posts about ''aspect ratio'' ?

Resolution is the key word here.

Yes, all Blu-ray movies are encoded at 1920x1080. Does that answer your question? The answer really doesn't get any plainer than that.

Valid resolutions are 1080p, 1080i, 720p.

1920x1080
1280x720

The vast, vast majority are in 1080p. You can check the stickied specs thread to find some of the weird ones if you want.

Topic done...

He's not off topic, your question is...odd and shows a lack of understanding of HD material.

Most blu-rays are 1920x1080, or 1080p (same thing). there are a few oddballs that are at 1080i but those are the exception. Not sure what you could possibly mean by you are seeing blu rays at 1280x1080 unless you are seeing movies at 2.35:1 AR and thinking that means something different.

All Blu-ray feature films as far as I know are encoded at 1920x1080.

Though the resolution it was recorded in or the true resolution of the source could be lower, like "28 Days Later" was mostly videoed in standard definition but that's still encoded at 1920x1080, but it's not really got 1920x1080 of real resolution because it was shot in standard definition. It could also be that a film encoded at 1920x1080 has a true resolution of only around 720p.

You could have really blurry/soft focused/DNRed films that are low resolution but encoded at 1920x1080.

And, because of the aspect ratio many films will have hundreds of black lines encoded into the picture. eg. if a film was 2.40:1, it would only have about 1920x800 pixels used for the actual motion picture, the rest would be used for encoding the black bars. Also, because Blu-ray titles are encoded with 4:2:0 colour, the colour information is not stored for every pixel. Because of compression, the actual real resolution that could be stored could also lower.

Helps to distinguish format resolution, (1920X1080 for Blu-ray), and resolvable detail or effective resolution (http://archive2.avsforum.com/avs-vb/showthread.php?p=5667245&&#post5667245). For a "HD misconceptions" thread under development, I just proposed (http://www.avsforum.com/avs-vb/showpost.php?p=17095240&postcount=12) a highly condensed summary of this topic, which really needs follow-on to the sublinks, expert attributions, and subsequent posts. But the gist is that ~1280 horizontally (effective, not format resolution) is likely too optimistic for many movies. And the "full 1080p vertically" only takes place with test patterns (non-sampled), as outlined in this recent post (http://www.avsforum.com/avs-vb/showpost.php?p=16986584&postcount=12). -- John

There should be enough information/links from John and others to get you started. If you feel the information does not answer your question in general...please PM me and I'll reopen the thread with very specific follow questions you may have.
