Ive got an Multiscreen setup on my Retropie(RBP4) and I want to use the second screen for the seccond DS Screen. Out of the Box drastic allready does this, but with a big flaw, which makes it unusable to me: the main TV gets scaled down to 720p instead of its 1080p and drasic than creates a fullscreen wiondow over both screens, resulting in a big missing part of the game on the main screen. Sadly Drastic also doest use the defined display config in which Ive set everything up perfectly.
It would be cool if drastic could support multi monitor out of the box or atleast allow to do some basic screen config that will be run on startup (for example done with xrandr)
