Does anyone know where I can find documentation for what input I can use for skipping the synchronization tests? I am unsure what the difference is between Screen(‘Preference’, ‘SkipSyncTests’, 1) and Screen(‘Preference’, ‘SkipSyncTests’, 2).
help SyncTrouble gives some background, but basically: Level 1 shortens the startup correctness tests for timing, and makes PTB continue even if it detects visual timing problems in your system. Level 2 disables all tests and calibrations - a quick startup, but visual timing can be considered broken/untrustworthy. For proper data collection where timing matters, only default level 0 is acceptable for full tests and error abort if anything problematic/wrong is detected.
