Projection > Output Setup > Keystone/Warp
You must create a keystone/warp setup for each output in a multihead setup. To to this, select Create Keystone/Warp
from the Options pop-up to enable Keystone or Warp functionality. The interface will default to Keystone mode.
Switch to Warp mode by clicking on the relevant radio button at the bottom of the window.
Keystone mode is shown as a 3x3 array of rectangles, with five of the rectangles having large, blue points and the
other four rectangles having small blue points. The points are a visual reference for the amount of transformation of
that area of the keystone surface. Keystone mode allows you to adjust the four corners by changing the position of
the four corner points and to adjust the linearity of the entire image by changing the position of the center point. The
smaller points will reposition themselves to remain on a straight line between adjacent corner points. You cannot edit
these intermediate points.
Click inside the rectangle that contains the area you want to adjust. The corresponding point turns yellow indicating
that you can use the mouse to click and drag to adjust the geometry. You may also use the keyboard arrow keys to
move in a more precise fashion, using the [option] key for even finer control. Note that the points can move outside of
their original rectangle in any direction, and that it is the selection of the original rectangle (their "home base") that
selects the point, rather than a selection of the point itself.
Double-clicking inside a rectangle will reset the geometry for that area of the output. Pressing the "Reset All"
button will reset all geometry.
