how i did it was:
1. open the EMC .lua installer and press "Install"
2. start up EMC and make a new .lua profile or open one that was working before
3. place displays how ever you want
4. save the .lua profile with the EMC proggie to the dcs location
5. go back to the EMC .lua installer and then press "Uninstall"
6. start DCS and set your resolution and load the profile
7. go kill bad guys :pilotfly:
hope this is helps everyone .I'll try to post pic later if need be.
let me know if this works for ya
