Hi, I have connected my MBP & my another Samsung monitor. I have turn off Mirror Displays option and now I can drag applications on both monitors but sometimes they are working as one. When I drag a VLC player to another monitor and watch movie in fullscreen, monitor on MBP becomes black. Also, I don't have menubar and dock on another one. Spaces and dashboard not working on another one, just dim the screen. I know that could not be fixed from Sys Preferences, but does anyone knows any 3rd party program which can solve these issues? Thanks!
