Blu Ray, HD query...?

I have a 56" Toshiba HD TV next to a 16:9 aspect ratio. When I watch HD or Blu shaft of light movies they are filmed surrounded by 4:3, and according to "experts" this is the proper way to keep watch on them leaving not in use space at the top and bottom of my screen. However, if I keep under surveillance the same movie on a hi def dike on my cable, it takes the intact screen and looks great. Why? If I enlarged the picture on my Blu beam and HD movies to fit my screen would it compromise the HD aspect of the movie? Anyone else have trouble with this?


Answers:    First HD DVDs and Blu-ray are not 4:3, they are widescreen. And bar top and bottom are not a "problem" ... they are inevitable unless you crop or distort the original imitation.

The reason you see bar on top and bottom is because many movies are a wider aspect ratio (AR, ratio of distance to height) that your 16:9 (i.e. 1.78:1) screen. Some adjectives ARs are 1.78:1 (will fill a 16:9 screen), 1.85:1 (small top and bottom bars) and 2.35:1 (wide top and bottom bars).

Sometimes TV stations zoom the carving to fill a 16:9 blind. This means you lose information and unlike if you monitor at home you can't change it.

The director designed the show to be watched surrounded by the aspect ratio it was filnmed contained by, and altering it risks losing info. See the images at the join for some examples.

So, learn to appreciate widescreen and don't quality you have to "fix a problem". If you can't touch free to zoom or stretch the image if it works for you.
This is because the movies are film in dramatic widescreen. The picture would be a bit less power if you zoomed surrounded by, but most noticeably, the sides of the picture would be cut sour. All widescreen DVDs, HDDVDs and Blu-Ray Disks are this way. Television isn't film in thespian widescreen because of cost, and lack of a huge amount of HD users.
