System Procedures
TwinView Edge Blending
To configure TwinView displays that require edge-blending (refer to Figure 3-4 ) between
the two display channels with a 10% overlap, use the following entries:
Option "TwinView" "true" # turn on dual channel mode
Option "MetaModes" "1920x1200, 1921728+0"
The
+1728
in the option line above commands the graphics card to start the second
channel at 1728 offset from the lower left hand corner of the first channel (the origin).
