Bezel correction and multiple displays

Graphics / Linux Linux

I am using a GeForce GTX1080 card but I would be happy to change to the Quadro if that is simpler. I am wondering how I can compensate for bezel sizes with multiple monitors (same brand and model) when using 3 monitors on this card.

I currently have TwinView setup which works awesome. I get a large X-Display and the 3D application I am using renders beautifully in it. However, because it sees one large 4320x900 monitor, the bezel splits the scene unnaturally and I am trying to correct for that so the bezel will essentially conceal the portion of the scene it would naturally cover.

I have done that successfully using SLI in spanning mode on Windows, but I have no idea how to even go about it on linux, especially on one card where SLI is not available.

I think setting up a metamode in xorg.conf with offsets larger than display width/height should suffice, like for two FHD displays:

Option "MetaModes" "GPU-0.DFP-0: 1920x1080 +0+0, GPU-0.DFP-1:  1920x1080 +1950+0"

That works. It has complications, but I can manage them. Thanks!
