Multi Screen stimulus presentation #1

Open Giaco-am opened 5 months ago

Giaco-am commented 5 months ago

Hello, I've an experimetnal setup which counts one workstation (with an NVIDIA RTX 4060 GPU) connected via 4 HDMI cables to 4 TV monitors which are selected by PsychoToolbox as 4 different screens through the Screen function. I want to present Drifting sinusoidal gratings on each of the 4 TV monitors at the same time (or rather in a seemingly continous manner). Is there a way to change the code to generate the stimuli on the 4 tv screens instead of just one? Thank you in advance, Giacomo

Hi Giacomo. Unfortunately, I have not tested in multiple monitors. It may be a good idea to duplicate your screen, in that case you do not need to do anything else to the code. My program uses psychtoolbox. Their documentation says that you need to configure “displays for exactly the same color depths, resolution, and refresh rate if you want to present stimuli across multiple displays” (http://psychtoolbox.org/docs/SyncTrouble). Let me know if this is useful.

Hello! I have an experimental setup where a computer controls 2 monitors and plays different raster stimuli at the same time, I wonder if this can be achieved by modifying the code? Thank you very much and look forward to your reply.

Thank you for your reply! Thank you for writing the program! It really helped me a lot! Hope to have a chance to communicate with you more in the future! Wish all the best！
