Here is something as a background info:
Black bars are normal on your TV under certain circumstances. This is because the programmes shown on TV were originally shot in a number of different aspect ratios.
Movies shown in theatres are typically shown in a wider ratio (1.85:1 - very close to 16:9) - or they can be shown in 2:35:1 (a picture much wider than tall)
One way that this has been dealt with is with "pan and scan", which involves removing pieces of the picture to fit the screen. A whole bunch of movies are pressed in their Original aspect ratio (OAR) - as the director intended - mostly widescreen. These are the movies that create bars above and below on
standard TVs. The programming shot for standard TV's creates bars to either side of the image on widescreen TVs.
Here are some basic descriptions of the various "black bars":
- 16:9 High Definition Programming:
True High Definition Programmes are 16:9 and you will see no black bars on your widescreen TV.
- 16:9 High Definition Programming, originally shot in 2.35:1 aspect ratio (2.35:1 OAR).
Some movies will be shown this way and it is normal to have black bars above and below the movie/programme. Most TVs cannot properly stretch HD images, so you are "stuck" with the black bars.
DVD players have a menu for selecting "widescreen or 16:9" TVs. This should be set to 16:9 or widescreen when watching DVDs on a widescreen TV.
- 1.85:1 Enhanced for Widescreen (Anamorphic) DVDs
These DVDs are the correct aspect ratio to fill a widescreen TV. You will need to set the TV to it's "horizontal only stretch mode" to properly see this type of movie. There should be no black bars (or the black bars may be very thin). If you use the vertical and horizontal stretch mode by mistake, everyone will be tall and skinny. Many newer HDTVs do this automatically.
1.85:1 "Standard" DVDs (Not Enhanced for Widescreen (non-anamorphic))
These DVDs are the correct aspect ratio to fill a widescreen TV. You will need to set the TV to it's "horizontal and vertical stretch mode" (zoom) to properly see this type of movie. There should be no black bars (or they can be very thin).
2.35:1 Enhanced for Widescreen (Anamorphic) DVDs:
These DVDs have an aspect ratio that is much wider than it is tall, so it will not fill a widescreen TV. You will need to set the TV to it's "horizontal only stretch mode" to properly see this type of movie. There will be black bars above and below the movie. If you use the vertical and horizontal stretch mode by mistake, everyone will be tall and skinny.
2.35:1 "Standard" DVDs (Not Enhanced for Widescreen):
These DVDs have an aspect ratio that is much wider than it is tall, so it will not fill a widescreen TV. You will need to set the TV to it's "horizontal and vertical stretch mode" (zoom) to properly see this type of movie. There will be black bars above and below the image. If you absolutely cannot stand the black bars, you can use the DVD player's zoom mode to zoom in on the picture and eliminate the black bars, however, you will now miss the "outermost" parts of the movie and you will not be seeing what the director intended.
These DVDs are the correct aspect ratio to fill a 4:3 TV. You will either see bars on the sides, or you can use one of the stretch modes like you do for any standard definition signal.
