Windows 7: Is it possible to see the same thing on one screen while using 2 card

Is it possible to see the same thing on one screen while using 2 card

I have GTX750TI connected to the HDMI port of my monitor and HD4600 connected to the D-SUB port of the monitor.

What I'm trying to achieve is to see the same thing while switching between HDMI and D-SUB modes.
With Win+P I can switch to "Duplicate" but then the D-SUB shows black screen.

Does duplicate work only if you are using the outputs of one card not two?

Do you have only 1 monitor? If yes, then why are you trying to duplicate the screen? What are you trying to accomplish?
Try duplicating from Screen Resolution window (right click empty desktop area)

What`s the purpose of the HD4600 and what`s the purpose of duplicating the monitors ?

I mean, you`re not gaining anything.

Do you mean the cpu graphics (HD4600), and the vga port on the motherboard ?

To duplicate one monitor onto another they need to be on the same graphics card.
