Can we use Xrandr to configure two monitors as one big display using Nvidia Drivers.

I have three GeForce GTX 690 graphic cards with the latest Nvidia Driver version 340.46 installed on a Linux machine and we have two monitors attached.
Can I configure both the monitors to set as a single display using Xrandr instead of using Xinerama with Nvidia Drivers?

Does this have anything to do with CUDA Setup and Installation? You’re more likely to get help by posting in another area that is more suited to your question.
