3.3.6 Aspect Ratio

The aspect ratio of any picture is its height divided by its width. H ÷ W = Aspect Ratio

The native aspect ratio of the Bay Cat screen is 1.77,

which is sometimes referred to as 16:9. This is the

HD1920 picture format.

1920 × 1080 pixels

1920 ÷ 1080 = 1.77

Many pictures do not have this aspect ratio. Stan-

dard television is 1.33 and HDTV is 1.77. Movies

from DVDs vary depending on the original film for-

mat, often 1.85. The larger the number, the “wider”

the picture seems.

When the incoming picture is a different aspect

ratio from the screen, Bay Cat gives you four choices

to make it fit. (These are “radio” buttons; you can

only choose one.)

Fill Both Ways makes the picture fit top-to-bottom

and left-to-right regardless of how this stretches or

compresses the picture.

 Fill Both Ways distorts the picture, when the aspect

ratio of the incoming picture is not the same as the Bay

Cat screen, 1.66. The other three choices (below) do

not distort the picture.

Keep Aspect Ratio/ Fill One Way fills the screen

top-to-bottom or left-to-right, whichever way fits

first. If the aspect ratio of the picture is less than

1.77, such as normal TV’s 1.33, the screen will show

blank areas on the left and right.

If the aspect ratio of the picture is greater than

1.77, such as wide-screen movies of 1.85, the screen

will show blank areas at the top and bottom.

Keep Aspect Ratio/ Crop fills the screen completely

without distortion, but crops the picture on one side

or the other. If the aspect ratio of the picture is less

than 1.77, such as normal TV’s 1.33, the picture will

be cropped (chopped off) at the top and bottom.

If the picture’s aspect ratio is greater, the picture

will be cropped at the left and right sides.

1 to 1/ Keep Original Size maintains the original

size and aspect ratio of the picture. This may leave

blank areas on all four sides. For instance, a VGA pic-

ture (640 × 480) will occupy only a small area in the

center of the screen. For UXGA sources, this will crop

the picture top and bottom.
