Cloning 3 2K monitors + hot keys to switch to single 4K display

Hi,

Sorry if this has been asked before - I've searched the forums to achieve my ideal set-up but haven't found exactly what I'm looking for. I have a trial version of DisplayFusion Pro and am trying to figure-out how to get the following set-up, if possible

FIRST ISSUE

My PC has 2x980Ti GPUs, running in parallel with 2K 60Hz resolution to all displays during normal use:
    1. 1x2K monitor (connected to DisplayPort on GPU1)
    2. 1x4K TV (connected to HDMI on GPU1) + Surround Sound 1
    3. 1x4K TV (connected to HDMI on GPU2) + Surround Sound 2

Windows 10 / DisplayFusion is only able to clone #1 & #2 or #1 & #3, not ALL three like I want. From reading the forums, it seems like all three need to be connected to the same GPU to achieve this cloning (which is weird since I can still clone #1 & #3 on different GPUs??). If that's the case, all I need is a DP to HDMI adapter to be able to connect all displays to GPU1 and I'm good, right?

SECOND ISSUE

Once I am able to clone all 3 monitors, I'd like to set-up this as the default profile with the option to switch to the following "movie mode":
    1. Switch to only displaying on Display #3
    2. Switch to 4K resolution
    3. Switch to Surround Sound 2

Is this all hot-keyable?

For the first issue, that's actually surprising that you're able to clone 1 and 3! Maybe a recent Windows Update or NVIDIA Driver Update is helping there. As for cloning all 3, I would imagine if they're all connected to the same card it should work, but can't guarantee it, as some cards/drivers seem to have their quirks.

For the hotkeys, you can definitely do that. Setup a Monitor Profile for each configuration, and then you can assign key combinations to them in the Manage Monitor Profiles window

Hope that helps!

The DP to HDMI adapter worked! I am able to clone all three displays. It didn't work through Windows 10, but Nvidia Control Panel allowed me to do it.

That said, when I tried to save the profile in DisplayFusion, it forced me to "apply" settings first. Since Windows 10 can only clone 2 displays, I believe DisplayFusion doesn't recognize that all three monitors are cloned (see attached). When I click "apply", DisplayFusion switches back to cloning 1+3 and extending display 2 -- which is not what I want.

Any ideas on a workaround?

DisplayFusion has to use the Windows API in the backend, so if it's not working in the Windows display settings, it won't work in DF either

Most likely the NVIDIA Control Panel is doing something driver-specific to make this work.

Ah, bummer. I'll just have to set-up the 1+3 and extend 2, then manually change it to clone all 3 using the Nvidia control panel. One extra step won't kill me... I guess!

Thanks anyways!
