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.
