Menu:
Zoom Center: Horz or Vert
This menu is used to position the video input when “Video Zoom” is greater than 100%.
The position is displayed in percent. Adjustments are made in the horizontal or vertical
direction, indicated on the top line. The direction is selected by pushing the Knob.
(Note: This setting has no effect if “Video Zoom” = 100%.)
Push Knob to select direction for adjustment.
Use the +/- buttons to adjust in 5% increments.
Use the Knob to adjust in 0.5% increments.
Menu:
Aspect Ratio Conversion:
This menu configures how video images are converted from one aspect ratio to another.
These settings only apply to standard video aspect ratios of 4x3 and 16x9. Some VGA
formats may not be converted.
Use the Knob or +/- buttons to adjust.
The display indicates how both directions are processed for a given setting.
16x9 → 4x3 = [off (anamorphic)]
4x3 → 16x9 = [off (anamorphic)]
Anamorphic:
In this configuration, there is no processing. The image will appear stretched
vertically or horizontally.
16x9 → 4x3 = [16x9 Letter Box]
4x3 → 16x9 = [ 4x3 Pillar Box ]
Letter / Pillar Box:
In this configuration, black padding is added to the image to maintain the original
aspect ratio. For 16x9 to 4x3, black bars are added to the top and bottom to produce
a letter boxed image. For 4x3 to 16x9, black bars are added to the left and right
sides to produce a pillar boxed image.
16x9 → 4x3 = [14x9 Letter Box]
4x3 → 16x9 = [14x9 Pillar Box ]
14x9 Letter / Pillar Box:
In this configuration, a combination of black padding and cropping is performed.
For 16x9 to 4x3, the sides of the image are cropped to produce a 14x9 aspect ratio.
Black bars are also added to the top and bottom to produce a letter boxed image.
For 4x3 to 16x9, the top and bottom are cropped to produce a 14x9 image. Black
bars are also added to the left and right sides to produce a pillar boxed image.
16x9 → 4x3 = [ Center Cut ]
4x3 → 19x9 = [ Vertical Crop ]
Cut / Crop:
In this configuration, portions of the image are cropped to convert to the new aspect
ratio. For 16x9 to 4x3, the sides of the image are cropped (also known as center cut)
to produce a 4x3 image. For 4x3 to 16x9, the top and bottom are cropped to produce
a 16x9 image.
