I have never used NVidia Surround (2D) and am considering a monitor upgrade; I want to be sure it will work before I buy. I have an NVidia GTX 1080 Ti and want to play some games I already know are compatible with wide resolutions, like Forza. I want to buy a 40" 4k monitor for the center and then on the sides pivot two 1080p monitors to portrait mode.
I want/expect black bars on the top and bottom (or just top only/bottom only) of the center monitor running at a slightly reduced visible resolution of 3840x1920, and both side monitors will run 1080x1920. That's a combined res of 6000x1920. All connections will be HDMI or DP.
Will NVidia Surround support this as I've described?
(Side note: AMD described how they added support for EyeFinity configs like this years ago, but I can't find any recent reference to whether NVidia supports this.)
