WARNING: Couldn't compute a reliable estimate of monitor refresh interval! Trouble with VBL syncing?!?


----- ! PTB - ERROR: SYNCHRONIZATION FAILURE ! -----

One or more internal checks (see Warnings above) indicate that synchronization
of Psychtoolbox to the vertical retrace (VBL) is not working on your setup.

This will seriously impair proper stimulus presentation and stimulus presentation timing!
Please read 'help SyncTrouble' for information about how to solve or work-around the problem.
You can force Psychtoolbox to continue, despite the severe problems, by adding the command
Screen('Preference', 'SkipSyncTests', 1); at the top of your script, if you really know what you are doing.


错误使用 Screen
See error message printed above

上面是MATLAB的报错信息,请问这个问题有解决方法吗

试试加这三行代码
Screen('Preference', 'Verbosity', 0);
Screen('Preference', 'SkipSyncTests',1);
Screen('Preference', 'VisualDebugLevel',0);

Screen('Preference', 'SkipSyncTests',1);
Screen('Preference', 'VisualDebugLevel',0);
