I’ve encountered a problem with my Custom Position Projector screen setting not being followed by Quelea until I turn off the Custom Position feature, then click OK, then turn the feature back on. This process is currently necessary every time Quelea is started, prior to displaying songs, etc.
It took a lot of experimenting with the settings on that Options screen before I figured out what worked best initially (earlier today when hooking up our Windows 10 PC in our A/V booth). My large screen monitor does not display proper alignment unless the settings I manually entered into the display screen in Quelea (2020.0) are in effect.
I think the problem noted above started after I tried selecting the Apple Play option on our external Projection Display switch box and then switching back to display the PC’s output. I did this because it is not unusual to do this during a service to facilitate showing a presenter’s wireless Apple based materials on the projection screen.
I’ve tried adding the “use.auto.extend=true” statement to the quelea.properties file without any visible change resulting.
