Toggling full screen mode on and off in Pavlovia?

Hi everyone,

I just did a bit of research to see whether this question has been asked before but didn’t find a topic.

Is there any way to run Pavlovia experiments in browsers without triggering the full screen display? To just have it displayed like a regular browser tab?

The reason why I ask is I may send my survey to older people who might worry if they see the screen suddenly taken up by an external page.

All the best,


Hi Cameron,

I am not sure if either of these would work, but here is two possible solutions off the top of my head.

Firstly, you can go into the experiment settings, go to the screen tab, and make sure the box with ‘Full-Screen Window’ is empty.

Like so:

Alternatively, and I am not sure if this will work, you could try putting this code in the begin experiment tab of a code component in your first routine:

windowAlreadyInFullScreen = false; 

Sorry I cannot give you definite answers, hopefully someone else can!


First solution seems to work :slight_smile: Thank you !
