With this in mind, would a setup like this be possible where the VR headset alone counts as two monitors? I have been getting conflicting information on this, so I am looking for clarification. If I go with an Nvidia card, I had been planning on going with a 1080 TI, I am however not familiar with the modern Radeon cards from after they stopped using the ATI name.
it doesn't matter what video card you got with, none of them can handle Surround View of 4x 4K display
so, needless to say 4x 4K screen + VR headset is definitely a no go
now lets step back a bit so you can understand.
Because I already tried, and the result is grotesk at best.
The performance of 3x 4K screen is already super laggy, even with SLI GTX 1080.. even with 2x GTX 1080 TI, it won't change that.
To get decent performance you can only got 1x 4K screen, or 1x 4K screen + VR headset.
Now lets revisit again why the 4x or 3x screen + VR headset is a no go
I currently have that setup, and I had to move my VR headset to another computer (home theatre PC) so it can work properly, because when you have 3 or more screen setup, the VR headset will simply "mirror" the physical setup, and that generates a squashed view of your screens, and makes the picture very tiny.
so imagine 4x 4K resolution downgraded to 1080p in your VR headset, that will make a very narrow lane across your eyes, and everything in it squashed.
That's how it looks like to me.
When I ran the 3D mark VR test, i didn't quite understand why it was doing that weird thing, until I realized
So to get the VR to work properly I had to unplug all my extra monitors, to basically have either 1x 4K + VR or 1x 1080p + VR.... as long as it's a combination that generates a proper scaling of 1080p then it can display properly on the VR.
Now this might just be an issue with the Steam VR, but other VRs might work the same way.
From what I understand it's actually the video drivers doing the work, so it might actually be the video card doing that.
Another thing to note.
at least with nvidia cards, you can only do Surround + Accessory display, or Surround + VR, but not Surround + Accessory + VR ... because I tried and it won't do it.
Now there is a work around if you really want an accessory display to see heat temp, fan, and OC data, or walkthrough guides, etc, get one of those USB monitor display, and plug the extra monitor via the USB, that will count as a separate video card
so you can still have the 3x screen + VR... but as mentioned before the 3x screen looks horrible through VR, because the VR will only render the center portion of the 3 screens.
That's why... I decided to run VR on a completely separate machine (my HTPC) so that it's a 1:1:1 ratio.
while I keep my gaming rig on the 3+1 display setup.
on the HTPC I have a single GTX 1080 that runs great on all big screen TV 60" + the VR + the Projector for the 50 ft wall
