The user manual is here, @7pip and the rest of the community are welcome to edit and build upon what is there:
@luix It sounds like you have Memory Palace in external sync mode. You can only select the NTSC/PAL format in internal sync mode. In external sync mode, Memory Palace will detect the sync format from the external source (patched to sync input on the rear.)
@gaeljaton Not sure. Which model power supply are you currently using and what is the total current load on it?
