As a triple monitor user, one of the most frustrating aspects of my setup is the inability to quickly toggle SLI for gaming purposes. I run triple monitors when working, but I game on a single monitor with SLI enabled.

Display Fusion solves half the problem, in setting up hotkeys for monitor configurations... At least now I can swap between a gaming config and a working config.

If you could add a hotkey, either separate or integrated with the monitor configuration hotkey, to toggle SLI on or off, I would gladly give you my money!

If it helps, I have read that there are command line options to manipulate NvCpl.dll to achieve this outcome, so if you could could find the proper documentation it might not be too hard to implement. I'll see if I can get some more details if you'd like.

I did some more digging into this, and it looks like the best chance of developing this feature, maybe the only way, is to have the NDA version of the NVAPI. This version houses the specific operations for SLI control on the video card.

This is could easily be a highlight of DisplayFusion should it be implemented, as currently there is no software available to toggle SLI whatsoever! Be the first, and I'll spread the word like wildfire!

Just got my third monitor set up and would definitely love to see this feature implemented. I've been experimenting a bit on my own with whatever public documentation there is of Nvidia's NvCpl API but so far I've been unable to achieve any noteworthy results. I fear, as Chad mentioned, that developer access to their API is needed to make this work.

Mr. Lammers and team

I have been using your wonderful program on every computer i have, even if it only has one monitor.

Needless to say I was hopping you could look into adding Spaces, or Mission Control (in Mac 10.7) or something like it, just as an example.

Thanks for getting back, I will certainly utilize that feature a lot!

I'm in the same situation and looking for a solution. Is there any progress regarding this topic?
If displayfusion could manage SLI i would definitley give it a try.
