SLI + Dual Monitors

Hello everyone,

I have been searching for an answer to my particular question, however, to no avail. I only saw related questions and answers, yet, not addressing my issue.

I have two GTX Titan cards connected via SLI. I also have two monitors, connected to a different card each, using DisplayPort. Enabling SLI disables the monitor which is connected to the secondary card. By me, it is perfectly fine to have one of the monitors disabled while gaming.

Yet, having to manually enable/disable SLI ("Maximize 3D performance" or "Activate all displays") each time I want to play a game is annoying, to say the least: when reverting back to "Activate all displays", display order is being reset, which requires re-configuration of the display order. Is there a way to automate all of this (say, when an SLI-supporting game is launched, SLI enables automatically; reverted when done playing)?

I'd prefer not to switch one of the monitors onto the main card as I prefer using DisplayPort. Got only one DisplayPort port on each card.

Thanks in advance!

Have you tried just loading everything in windows versus full screen ?

i think with the newer nvidia cards the monitors need to be connected to the primary card to remain active when sli is enabled.

connect one to the displayport output on the primary card and the other to the dual link dvi.

Thanks for the prompt replies.

I will connect both monitors to the same card if I will have no other choice. Yet, I wanted to use DisplayPort. Connecting both monitors to the same card will incur connecting one of them using DVI-DL, something I am trying to avoid. Hoped there is a software solution for this.

Also, I don't really mind that the second display be deactivated when playing. What I am trying to achieve is a scenario in which SLI itself will be enabled only during gaming, and then disabled -- automatically. :)
