Remarks

This property reports the vertical refresh rate in Hz of the display system.

The vertical refreshrate shows how often the current display screen can be refreshed per second and thus, how often different stimuli can be presented per second by your script. RefreshRate and refreshInterval are interconnected; e.g. a 60Hz monitor can present 60 different stimuli per second with a presentation duration of 16.67ms each (refreshInterval).

Examples

The following displays the value of refreshRate in a text stimulus:

<text myText>
/ items= ("refreshRate = <% display.refreshRate %>")
</text>

The following displays how to store the refreshRate in the raw data file.

<data>
/ columns = (display.refreshRate)
</data>
