I was having a lot of problems with 2.4 that I won't get into at the moment so I decided to give 2.2.1 a try as our church is in a transition to Linux from Windows. The only real issue I'm having is OpenLP-2.2.1 won't detect my connected 2nd monitor. I have to use override and set dimensions that way. What would cause the app to not detect my 2nd. My second monitor is connected through Displayport -> HDMI adapter cable. Not sure if that means anything. I should also add that 2.4 detected the monitor without a problem.
