As we all know most BD movies are released in 2.4:1 aspect ratio, which is also known as Panavision or CinemaScope. A popular aspect ratio for major movie releases. Historically, this aspect ratio was actually 2.35:1, but it switched to 2.39:1 in the 1970’s. It is also commonly rounded up to 2.40:1. Therefore you may see any of these three versions recorded on the Blu-ray or DVD box – although they are essentially the same thing.
The 4:3 television will have huge black bars at the top and bottom, and the movie will be that small colourful bit somewhere in the middle! Again, as with the previous aspect ratios, zooming in can reduce the bars but it will also make the image less-defined and cause a loss of the picture at either side.

2.39:1 Image on a 16:9 TV
On the 16:9 TV, this is probably the one that annoys people most. We spend all this money on a huge 60 inch widescreen technological phenomenon, and then when we play a DVD or Blu-ray a third of the screen is covered with black bars at the top and bottom!
In order to play 2.4:1 Blu-ray movie at full frame on 16:9 HDTV without black bars, we need to Crop the 2.4:1 anamorphic image to fit for 16:9 displays.
In this way a portion of the widescreen theatrical image of a film is selected to fill your TV screen. Letterboxed black boarders and partial of the image are cropped out across the widescreen film so that the left image will be just right for 16:9 screen (somewhat like pan and scan).
Pros: you get full-screen display of the movie and not lose aspect ratio.
Cons: this results in a loss of more than 25% of the original image.
