Warp
About
Image warping is the process of digitally manipulating an image to compensate for the distortion of the screen, typically by non
perpendicular alignment of the projector versus the screen. The image will then typically occur as shown inimage 8-2.
While an image can be transformed in various ways, pure warping doesn’t affect the colors.

Installation / Warp / 4 Corners Adjustment
Basically, this type of warping adjusts each of the four image corners in the X and Y direction, if you have a typical trapezoid picture
of the screen as shown above.
To have a successful Warp correction, the size of the screen must be entered. The size are expressed in the X and Y measured
values, independent of the term of the measurement. (mm, inches, yards or whatever), but must be expressed in whole numbers
without decimals. This means that the accuracy are higher when given in mm than in inches. The projector then calculate the aspect
ratio.
All four corners can be adjusted and the image correction is calculated accordingly using perspective algorithm. This can be used
for keystone correction.
Use the navigational arrows to adjust the image.
Changes occur dynamically to the image display.
How to adjust Warp
Enter the Warp menu, Enable the Warp button, and select the corners that must be adjusted.
Use the arrow keys to move the corners.
When
fi
nished, exit the menu.
