Dear colleagues,

We are interested in information regarding how to control accurate
stimulus presentation times on computer (video) monitors. In particular
we are interested in the confounding role of the REFRESH RATE (60
HZ), which seems to imply that stimulus durations must be multiples of
1/60th of a second = 16.67 ms.

Is this so ?

For instance, wouldn't it be possible to present a stimulus for an exact
duration of 25 milliseconds?

Any help is greatly appreciated.
