Timestamps do not fit with Hz of monitor
I have an experiment where words should be displayed for 28.5ms. Unfortunately I only have a 60Hz screen, so in the best case only 33.33ms would be possible. However, my timestamps show me sometimes 29 and sometimes 30ms, how can this be?
Another question is whether anyone has experience with overclocking the monitor? Is this advisable?
I use the xpyriment backend. Thanks a lot!
