Showing Attract Mode Displays on multiple monitors?

[wrybread]

I have two different monitors, each a different resolution. I'm wondering if it's possible to show a Display on both simultaneously?

I've enabled multi monitor support, but currently it simply blacks out the secondary monitor.

I see the "fe.monitors()" function in the layout docs, but it's not very clear how to use it:

Is there some way to make a second instance of the RomList on monitor 2? Or some other clever way to mirror the RomList Display?

Solved by simply drawing elements outside the range (to the right) of monitor 2. Works great. The only problem is that it keeps the Display on monitor 2 when playing arcade games. If anyone knows how to mirror a MAME game on monitor 2, I'd love to hear it. (And running my displays in mirror mode isn't an option).
