Notice!!
In some situations,  installing the Duo View driver will cause your screen to be 
distorted and possibly unreadable.  ATI, the maker of DuoView, is currently working 
to correct this problem.  Once the new version is released, we will update the driver 
as soon as possible.  If you experience this problem with the DuoView driver, we 
suggest that for the time being you use the Single View driver and request an update 
when it is available.
