which video card support dual head, opengl...

Hi,

Any one runs opengl application one dual head
video cards, and fast rendering in both display? My inno3d tonado Geforce2mx400’s
opengl driver can only accelorate the primary
display. Opengl is only optimized for one head for this card.

Need advice on this. dual head, both support opengl API and compatible with 2nd video card. (3 monitor system) which card should I
use.

Thanks,
Hillxy
