Don*t get confused::

Dual link is about supporting 1 monitor beyond 1920x1200@60 something that wasn‘t asked for.

Every card dating back to Rage has 2 outputs and can run 2 monitors indepentent, but only very few have that feature supported in MorphOS.

With the 256MB 96x0 you could indeed run 2560x1600 + 1920x1200, the 128MB 9600 will only d 2*1920x1200.
