Continuing the discussion from Different offset in cms for 2 client same pc:

You will want to open options for your second client and change the hardware key (display id)
where to do this?

All i can see is default.config.xml file which as following:

<?xml version="1.0" encoding="utf-8" ?> 900 0 0 0 0 10 true 2 schedule.xml log.xml stats.xml cacheManager.xml requiredFiles.xml WindowsMediaPlayer DEFAULT yourserverkey COMPUTERNAME blacklist.xml error Bottom Right I 0 10 900 5 5 false true true false true false true false 0001-01-01T00:00:00 false false 0 1 9696 0

You open the Xibo Player Settings application and the Display ID is there. You don’t need to edit any XML files.
