I am looking for a way to use my two 1080p monitors while gaming on my 4K monitor, however I am having issues making them all work with 2x SLI when using GTX 1080Ti cards. No matter what connection configuration I use between the two cards I can only get a maximum of one 1080p display to work.

I am using the latest drivers, Windows 10 Pro x64 with latest updates, etc. The cards are MSI Gaming X if that is relevant.

My optimal setup would be:

GPU 1:

  • Displayport -> 4K monitor
    HDMI -> HTC Vive
GPU 2:

  • HDMI -> 1080p monitor
    HDMI -> 1080p monitor
Any thoughts or ideas on what I could check or issues with this setup are welcome. If there is a way to do this I'd really appreciate it.

Here are some details on my specific situation and how I solved this issue:

For starters, I am using the BenQ GW Series GW2265HM monitors for my 1080p displays. These particular monitors like some other ones like it require a DVI connection to initialize, however after initializing I was able to switch to HDMI after initialization, which I did. However when I switched from non-SLI to SLI it would need to re-initialize, and there would be no DVI connection.

What I did to solve this, is I purchased two HDMI -> DVI cables, so now I can utilize the secondary GPU's HDMI ports, and the screens initialize as I switch between SLI and non-SLI.

Super happy it was such a simple fix.

I have tried all configurations of the different displays, as I said I can only get one 1080p to work with my 4K monitor. All the monitors work fine if I disable SLI

I don't think you understand, the only time I can get more than my 4K monitor to work is with just 1 1080p monitor plugged in GPU 1, without any other display units including the VIVE. As soon as I plug in one more 1080p display (identical to the first) then they both go black and stay that way.
