Two monitor profiles - 1 disable monitors, 2 enable monitors. Enable doesn't work

Hi - I have seen some discussions on enabling monitors in monitor profile, but non fit my problem.

My PC has an Intel i7-3970x CPU, 16gB RAM running at 1833mhz, Windows10 Home 64-bit.
I have a nVidia 1080 card. I am using a 4 monitor setup.
1 Benq 22" - which I use for general office type app use
3 Acer predator 24" monitors - which I use in nVidia surround, at a resolution of 6060 x 1080 (including bexel correction of 150pixels between each pair.
I also have an Oculus Rift VR set.

I suffer the usual issue of nVidia control panel frequently 'losing logic' with respect to the surround setup. It changes the order of the monitors, so the surround is mixed up, it loses the bezel correction and won't boot the Benq monitor. This means that I have to go in nVidia control panel, click on setup surround and re organise the monitors and set it all up again, with new bexel correction; and then go into multiple monitors and enable the Benq, move it to the left side of the surround virtual monitor and apply the settings. The nVidia control panel runs quite slowly so this can take 10-20minutes to complete.
This was why I bought DisplayFusion Pro, hoping it would bring some order to this chaos.

So. I find that the Oculus Rift will not come out of standby.
After much googling, and finding nothing except 'change the cables' type comments, I decided to go it alone :)
If I disable the 3 Acer monitors, the Oculus Rift wakes up and all is ok.
I created 3 monitor profiles

1. A monitor profile that disables the 3 Acer monitors. That works just fine.

2. For the 3 Acer monitors, without bezel correction.
3. For the 3 Acer monitors, with 150pixel bezel correction.

After loading 1. the Acer surround monitors are disabled and oculus rift works fine.
When I finish VR, I hope to be able to load either of the other two monitor profiles and resume a 3 monitor surround + 1 setup.
However, when I load profiles 2 or 3, the monitors stubbornly remain disabled :(

If I load monitor profiles 2 or 3 AFTER nVidia has 'lost logic' and the monitor order is incorrect, the profiles do not rectify that problem.

In both scenarios, I then have to go through the whole nVidia control panel exercise (described above) that I was trying to avoid.

So, I have two questions.
A. Why are the monitor not being enabled in the monitor profiles 2 and 3? (and how can I force a monitor re-enable?)
B. Why don't the monitor profiles place the monitors in the correct order? (and how can I force the monitors to do that?)

The correct order should be (from left to right) 1 Benq, 4, 3, 2 Acer surround.

I mainly play Elite Dangerous, Witcher 3 and Elder Scrolls Online. So having the surround monitor order scrambled makes gameplay impossible. :'(

Many thanks for any help with this annoying problem.

Cheers

Thanks for checking out DisplayFusion! Unfortunately I don't believe it can help here. DisplayFusion doesn't have the ability to enable surround or change the order of the monitors in the Surround configuration because it's all custom stuff in the Nvidia drivers

Thanks Keith.
I understand that Nvidia drivers control much of the monitor and display functions.
I can leave surround up to Nvidia.
However, I had set up a monitor profile that disabled three monitors.
That worked fine.
Can you tell me if I can set up a monitor profile that will enable three monitors?
It seems logical to me (probably wrongly) that if I can create a monitor profile in diplayfusion that will disable monitors, then it should be possible to enable them.
Cheers

You can setup a profile to enable 3 monitors, but they would be in extended mode, not Surround mode. The reason the disabling works is that the NVIDIA drivers seem to detect when the monitors are disabled or disconnected and automatically disable Surround mode, but they don't do it the other way.

Hi,

Based on the very first post here, I'd like to point something out.

the OP specified that when 3+1 are enabled, the VR headset refuses to come out of standby. There is a reason for this. It is a limitation of your nVidia card that limits the number of active displays to no more than 4.

3+1 (even when 3 are set as surround) is still a 4 display setup. Disabling any of the 4 monitors will immediately allow your VR headset to be used. Any time that the VR headset is active as a display, you will only be able to enable 3 of your 4 monitors.

Google isn't always helpful, and DisplayFusion can't override this limitation, so I hope this helps.

Thanks very much, Jason. I will look into that. Sounds like a plan to disable only one monitor when in vr mode.

Only problems is that when you don't want to game on the Rift anymore you'll have to disable the Rift somehow... If you want all other 4 monitors that is...

I don't know anything about Rift, but if it works anything like a normal display, and can be controlled by DisplayFusion, simply switching it to disabled should be enough.

The limitation is only on the number of displays actively in use, not by what is physically connected, or just powered on.

Example: In a 5 display setup, when 4 are in use, and you want to switch to another, simply setting one of the displays to "Disabled" and clicking apply, should allow you to select the 5th, to enable, and configure, in the Monitor profiles window. The now unused display will just get no signal from the 1080, until it is enabled with the appropriate profile.

Hope this helps.

Yeah I know how it works. It uses a HDMI but isn't visible as a monitor in Windows. Might be in DisplayFusion. Gonna hook it back up when I get home. What annoys me the most is that my Aorus GTX 1080Ti has 6 ports where one is shared between HDMI/DVI but still I can only use 4 at the same time... Nvidia logic...
