Aspect Ratio
There are several options to set the image's aspect ratio depending on your input
signal source.
Auto: Scales an image proportionally to fit the
projector's native resolution in its horizontal or
vertical width.
4:3: Scales the picture so that it is displayed in the
center of the screen with a 4:3 aspect ratio.
16:9: Scales an image so that it is displayed in the
center of the screen with a 16:9 aspect ratio.
Wide: Stretches a picture in a horizontal direction to
fit the screen width. It does not alter the height of a
picture.
Letter Box: Scales a picture to fit the projector’s
native resolution in its horizontal width and resizes
the picture height to the 3/4 of the projection width.
This makes a picture greater than the screen height.
The top and bottom edges of the displayed picture
are cropped. This suits the contents which are
produced in letter box format (with black bars on
the top and bottom).
Wall Color
Corrects the projected picture’s color when the projection surface such as a
painted wall which may not be white, the Wall Color feature can help correct the
projected picture’s colors to prevent possible color difference between the source
and projected pictures. There are several precalibrated colors to choose from:
Light Yellow, Pink, Light Green, and Blue.

Position
Displays the Image Position window. You may use the directional arrow keys on
the projector or remote control to adjust the position of the projected picture.
The values shown on the lower position of the window change with every key press you made.
This function is only available when the PC signal is selected.
Overscan
Adjustment
Conceals the poor picture quality in the four edges.
The greater the value, the more portion of the picture is concealed while the
screen remains filled and geometrically accurate. Setting 0 means the picture is
100% displayed.
