No Anti-aliasing on Extra Monitors

I use three monitors for my FSX-SE set-up. All three display VC view with the two outside monitors panned left and right respectively. This gives me 180 degrees of VC view with little distortion. The problem is I can’t get anti-aliasing to work on those two undocked windows on the extra monitors. I was hoping to have my graphics card do the anti-aliasing but I can’t get my Radeon RX 580 to do the anti-aliasing even with the latest drivers. I’ve already posted a thread about the Radeon card problem.

In this thread I’d like to see if there’s any way to get native FSX-SE anti-aliasing to work on undocked windows that are moved over to extra monitors.
