Can't connect dual display GTX 750 Ti

Hi guys,

It's my first post here and also my first instalation of El Capitan.

After the instalation, i tried to plug my 3 monitors, but the only one that works it's the one connected to VGA. The DVI Monitors don't show any image. I installed the web drivers, my Graphics name appears correct and everything else works except the other 2 monitors connected to DVI.

Any tip?

Thanks
