Changing size of content that is displayed full-screen on a second monitor


OS: Windows 10
PsychoPy version 1.85.6
**Standard Standalone? ** Yes

We were trying to use the monitor in the fMRI scanner as a second monitor to run our psychopy experiment.

However, a problem with the scanner’s monitor is that it cannot display all the content within the 19201080 monitor of our computer. This is because whereas the scanner’s monitor has resolution 19201080, the edges of the monitor are partially covered by a frame and the effective display size equals 1688* 1080 instead of 1920*1080. In other words, contents on the far left and right sides of the computer screen will not be visible to the participants on the monitor inside the scanner (as they will be covered by the monitor’s frame).

Therefore, we are wondering if there is a way to “shrink” the displayed content on the second monitor inside the scanner, without exiting full-screen mode, since otherwise it might be distracting for the participants. Is it possible to achieve it by changing the monitor resolution settings, either in PsychoPy or in Windows?

The only way I can think of to solve this problem is to change the size of the displayed content in PsychoPy; that is, to use texts and images that are smaller. However, this approach is not ideal, because it will require great effort in adjusting the polygon positions (which have been tuned to the current size and position of the images and texts).

Thank you so much for helping us solve the issue!
