ASPECT RATIO CONTROLS
» Aspect Ratio Operations (Manual)
There are four aspect ratios available that can be selected for video signal inputs.
When viewing videos or DVDs:
1. Press the ASPECT button on the remote control.
2. Within 3 seconds...
Press the ASPECT button again.
The screen size switches as follows:
LETTERBOX STD (4:3) ANAMORPHIC VIRTUALWIDE
LETTERBOX mode
The image in the Letterbox mode will be zoomed in, and the top and bottom portion
‘blanked off.’ This ratio is best suited for LaserDisc movies or non-anamorphic
DVD’s.
STD 4:3 mode
The image is displayed at a standard 4:3 aspect ratio.
The input signal will be scaled to fit in the center of the 16:9 screen.
NOTE:
Limit the amount of extended time displayed 4:3 images, as this
can cause a phosphor burn-in. (see page 5 for prevention)
ANAMORPHIC mode
The Anamorphic aspect ratio expands the image in the horizontal direction. The
image is compressed vertically, but with anamorphic software the image will appear
properly proportioned. This is best suited for use with 16:9 DVD’s.
VIRTUALWIDE mode
The VirtualWide mode is an aspect ratio is designed to fill the 16:9 screen with a 4:3
image. The center of the picture is not stretched, and it gradually stretches on the sides
reaching the most extreme stretch at the far edges of the picture. (non-linear scaling)
In addition, we apply a very slight vertical stretch uniformly (no graduation) which
results in a very small amount of cropping of the top and bottom of the image area.
Thus a 4:3 image is transformed into a 16:9 image with minimal distortion.
