I play with 3 monitors - all Dell SP2309W, native resolution 2048x1152 each.
NVidia GeForce GTX 1050 Ti
Windows 10 Pro 64-bit
"Span displays with Surround" is selected in the NVidia control panel
This allows WoWS to run full screen at 6144x1152. The game treats this as a single screen.
My most important game mod is the MiniMap enlarger.
My greatest complaint using this setup with WoWS is the horizontal scaling, i.e., the view gets stretched out more and more the closer it gets to the outside edges. Not the markers, lists, minimap, and all that, just the ships, islands, etc. - "the battle scene". Still, the view of the battle scene is wider overall, so I use it.
It would be great to have this wide view with no horizontal stretching, just a wider battle scene.
After a bit more research, I find:
Game designers generally design for a FOV (field-of-view), or range of FOVs, that is smaller than that of a 3 monitor setup.
The side screen stretching is also call fish eye, after the fish eye lens.
Software is available to even out the fish eye side screen stretching, but it does not increase FOV. Only the game maker can increase FOV.
I'm now searching these and other forums for the terms "FOV" and "fish eye". If I find good info I'll edit again.
