Three displays with GTX 670 -- duplicating desktop problem

Jul 30, 2012 5:56 PM

Just got a new computer with an Asus GTX 670 card.   I am running 3 displays:  1. (Main) Dell U2412M via DVI port,   2.  Old Samsung LCD monitor via DVI port with VGA adapter,  3. Samsung 59" plasma TV via HDMI port.  I am trying to duplicate the desktop on my TV, but the card will only allow me to extend the desktop to the TV.  TV goes blank when I try to duplicate the desktop.  I am able to duplicate the desktop on the TV when my third monitor is not connected.  My old Samsung monitor displays an extended desktop which is what I want.  

 

If anyone has figured out the workings of this new card, I'd like to know if it is possible to duplicate the desktop on my TV with my setup.   Thanks

    I don't believe Windows or the Nvidia driver allows you to extend/independent display 1 monitor and then duplicate the other. You will have to decide 1 or the other. BTW will the 670GTX handle all 3 displays as extended/independent?

    Yes, as I mentioned in my post, the GTX will extend the desktop to all 3 displays, that is, I can move a window from the main monitor to either of the other two displays.  I am trying to duplicate the desktop on my main monitor to the TV so they show exactly the same thing, as one would do in a presentation with a projector.   This is possible if I don't use a third monitor.

    Windows wont let you extend 1 monitor and clone the other. If you want to clone then you have to stop extending the 2nd monitor.
