I'm trying to get this to work as well. I have two monitors, and if I use live and EQW2 I can configure it to send an instance to my second monitor. I configure it to run with SoD and I can send an instance to my second monitor (best I can tell... it's confusing) but my keyboard doesn't work in it.
This only happens upon loading my second instance of SoD, no matter the account or .ini file I'm using.
Here's something I'm going to try (as I've dedicated my morning to getting this to work). I'm going to load a SoD into 2 folders, so the instances aren't sharing files as much (or at all, I'm not completely sure the differences between the live loader and the SoD one).
I know that an older version of EQW is supported, but as far as I can see, there's no command or .ini line where i can tell it which monitor to send the instance to.
If anyone has any input, I'd love to hear it, because having 2 monitors running full screen is a nerds dream =)
