My desktop has 2 HD 6450 graphic cards, each of them has one HDMI, one DVI and one VGA port. I connected 2 of my screens to the 2 HDMI ports on 2 cards, and I'd like to duplicate my 2 screens.
However, Windows doesn't let me do it, as there's no option to:
I can only extend the displays, or show the desktop on one of them, but cannot duplicate them!
Even if I connect one screen to the DVI port on one card and one screen to the HDMI port on the other card, it still won't let me duplicate.
If I connect them to different ports on one card only then it works fine - I can duplicate the screen.
Is there a way to duplicate the screens if they are connected to different graphic cards?
