Yeah, don't use full screen, use windowed mode. There is supposedly a mod that removes the top bar of the window too.
If you have two identical resultion monitors, you can 'split' the view and just stretch the monitor across two screens.
I have used fullscreen dual monitor, with the actual set-up in the game for a while, but it's just not stable making you loose all epic long-lasting games because the stuff freezes. I now just use one 30" 2560x1600 monitor with the game in windowed mode.
The other monitors have my discord, FAF client, Outlook... anything really.
