Hello!
This is my newly purchased system:
2 x Nvidia GTX 780 (SLI)
2 x Benq W1500 (Full HD)
Since I was switching from AMD to NVidia I could not imagine that spanning/surround/eyefinity with 2 x 1 displays would be a problem. What a nightmare when I realised this. Even with a 2 projectors and a third full HD display (monitor) I cannot get surround to working (re: sync polarity, I've tried to "trick" the monitor into being a projector without being able to enable Surround/Spanning. But that is another story).
However, I read on this forum yesterday about a device from ZOTAC that might save my setup. I need to have it confirmed.
Can the ZOTAC DP to 2xHDMI adaptor work for me if I need to do surround gaming with my setup?
Sometimes I would like to use only the TWO projectors (left channel 1920x1080 + right channel 1920x1080) and sometimes I would like to also use a third channel (like DCS setup with left channel 1920x1080 + center channel 1920x1080 and right channel/instruments 1920x1080 touch screen).
My typical needs:
Flight Simming:
On WALL: out the window display 2 x projectors
On Monitor: instruments, a touch screen monitor
Typical DCS, X-Plane, Prepar3d, FSX
Gaming:
On WALL, 2 x projectors
I'm not interested in 3d Vision at the moment (or whatever the term is for stereoscopic display).
So, As I understand, the ZOTAC will enable me to have a desktop/spanned output of 3840 x 1080 for my two projectors? That would solve the situation with gaming situations (Arma 3 etc) as I can use SLI and have the game in fullscreen mode projected on the wall only.
But, why is not Surround/Spanning working for me with 2xBenq W1500 (projectors) and 1xBenq XL2420T (monitor)?
The projectors are connected with HDMI and the Monitor is connected via DVI. It should be supported as in Option 1 in this guide.

However, I understand that the displays must match not only in size and refresh rate, but also SYNC POLARITY?
I've tried this guide: http://hardforum.com/showthread.php?p=1038794194 but was not able. However, I will try again later this week because I did not fully follow the guide
Any help and clarifications appreciated!
