MANAGING BLACK BARS

WHY ARE THE BLACK BARS STILL THERE SOMETIMES?

Motion picture film and cameras, and later television screens, were originally designed around a screen size that was almost square - it was one-third wider than it was high (another way to say this is that it had a width-to-height ratio, or aspect ratio, of 4:3. This ratio, 4:3, can also be expressed as 1.66:1.)

When widescreen movies using technologies like Cinemascope and Panavision became popular, new aspect ratios were used

for them - 1.78:1, 2.35:1, and even 2.55:1. When high-definition television was developed, a screen shape of 16:9, or 1.85:1, was selected as the best compromise for viewing widescreen movie images.

When you watch widescreen movies on a standard 4:3 television, there are “black bars” on the top and bottom of the screen. This is often called a “letterbox” image. The alternative is called “pan-and-scan”, where the edges of the image are “cropped” off.

This system uses a widescreen 16:9, or 1.85:1 display - the same aspect ratio as high- definition televisions. This means that when viewing widescreen DVD’s, these black bars are either non-existent, or greatly minimized.

There are three possible reasons for black bars to appear on the top and bottom of an A10 display:

1)You are watching a widescreen movie with an aspect ratio greater than 1.85:1. (For more options on dealing with this, see below). Check the disc jewel box to determine the DVD’s aspect ratio - if you see 2.3:1, 2.33:1, or 2.35:1, this applies.

2)The internal DVD player has been set for a 4:3 display instead of a 16:9, wide display. See DVD Setup on Page 23 to correct this.

3)The “widescreen” DVD movie you are viewing is not “anamorphic” or “enhanced for widescreen televisions”. These films, often older DVD conversions, are not recommended for viewing on widescreen displays. You can usually determine if your DVD was produced for optimum compatibility with widescreen televisions by looking for the word “anamorphic” or the phrase “enhanced for widescreen televisions” on the box.

WHAT CAN I DO?

First, Rosen recommends that for best results you use DVD’s that say “anamorphic” or “enhanced for widescreen televisions” on the box. However, this system can get rid of black bars with just about any DVD, by following the steps on the next page.

Note: To watch “fullscreen” DVD’s or broadcast television (using an optional TV tuner), you can use the DISPLAY MODE button to select “STANDARD”. This will properly size the image, instead of stretching the image across the wide screen. In “STANDARD” mode, you will see black bars on the sides of the image.
