Again, this distorted image is unacceptable. A few

high-quality standard video displays will allow for

the vertical size of the picture to be decreased,

restoring the proper image geometry. But since

nearly all standard displays lack any type of aspect

ratio control, this capability is instead built into all

video disc players.

By selecting 4:3 Letterbox for the TV Aspect Ratio

setting in the On-Screen Setup Menu (see page 68),

when a widescreen disc is played the player will

automatically squeeze the image vertically to restore

the correct geometry while adding black bars at the

top and bottom.

Additional Factors

So far everything has been relatively

straightforward. However, there are a few more cases

to consider that introduce some complexity to the

situation.

Very Wide Films

Many films are made with aspect ratios even wider

than 1.85:1, such as 2.35:1. Even on a widescreen

(1.78:1) video display these films would be distorted

if they were simply allowed to fill the screen.

Instead thin black bars are added to the top and

bottom of the image on the disc itself when the

transfer from film to video is made.

On a widescreen display these thin black bars are

perfectly normal and there is no distortion of the
