Exclamation 2.40:1 1080p -- Is somebody lying???

So I was reading the back of my BD case for Deja Vu, and just happened to notice that it was in 1080p, as expected, but at the same time 2.40:1. Wouldn't this mean that the movie was either 2592x1080 or more likely, 1920x800, which would make it NOT 1080p? Either way, nobody's TV would display it in the proper aspect ratio at the same time as 1080, right?

Have I missed some explanation of this somewhere?

The video is stored as 1920x1080, the highest resolution available on HD DVD (or any consumer format). Some of that resolution is being spent on black bars, but those black bars are part of the picture information on the disc, they are not added by the player or anything like that.

Your Blu ray is indeed 1080p. On your tv you can check the formats available such as wide screen and others, find the one that fits you.

Because some movies are shot in 1.85:1 which is near enough 16:9 hence fills a screen. Many other movies are 2.35:1 which means that in order to keep their original aspect ratio as it was in the cinema (i.e. see everything on the screen as you want to) it means you still get the picture letterboxed even on a "widescreen" display, because the film was shot in "even widerscreen"

Like HiramAbiff explained already, the transfer is indeed 1920x1080 but the area with black bars counts as vertical resolution as well. The part with the film itself is indeed "only" ~ 1920x800.

If your tv offers an option to zoom into the picture, thatīs more or less the only way to *get rid* of the black bars.

Itīs the choice of the director to have the movie presented in widescreen ~2.4:1. When watching 2.4:1 film at the theater, maybe you have noticed the curtains in front of the screen to open more to the sides right before the main feature starts? Thatīs the moment when the theater is adjusting the aspect ratio from the ~1.8:1 commercials to the ~2.4:1 feature film.

Tvs canīt do this (though it would be cool) since they have a fixed aspect ratio of 16:9. Hence the black bars to keep the original aspect ratio.

That would be realy cool.

Completly off topic but I watched a documentry about LG last night and hadn't realised before they were the ones who invented the HD tuner and just how many Plasma/LCD TV's they make, acording to the documentry as well as their own they manufacture screens for every other brand name in the west.
Anyway part of the program was a look at their R&D there was a prety cool wierles LCD, the new organic LED screens and then one of their senoiur engineers stated they expected to have a fully working prototype holographic TV by 2010!!

I alredy want one and am going to start saving.

Thought it would be worth pointing out that if you do take advantage of the TVs "zoom" function you will be stretching and distorting the picture and it will make everything look out of proportion. Bothers some people, doesn't bother others.

Actually it was Zenith who invented the HD tuner but since Lucky Goldstar bought them they can say they did.

Zooming the picture won't distort it, but you will end up losing picture off the sides and it will look less sharp as you are magnifying the pixels.
