Like the title says. For some reason I CANNOT get this card to duplicate its displays (in Windows XP.)

Unticking the 'extend desktop onto this monitor' box, which normally reverts to mirroring, just disables the second video port instead. None of the options in the Catalyst Control Center allow mirroring either.

Note that extended desktop works absolutely fine, no drama. The card is a Sapphire dual-DVI version (one monitor on each DVI port, no dual-link cable or anything like that.) I'm running the last driver that supports this card - driver v 8.970.100.0 / Control Center v. 2014.0107.544.10171 . Is there just no way to do mirroring on this card/driver revision?
