Hi Psychtoolbox Community,
I have a ViewPixx and a console monitor that I am attempting to mirror. My setup works fine with multiple x-screens (showing the task on the ViewPixx and the GUI on the console.
I’ve tried to instead create a configuration for a single x-screen with ‘AsyncFlipSecondaries.’ The console monitor has a native resolution of 1920 x 1200 @ 60 hz so it is a higher resolution than the ViewPixx (1920 x 1080 @ 120 hz).
From the help, it looks like the higher resolution display is selected as the primary display. When I use: PsychImaging(‘AddTask’, ‘General’, ‘MirrorDisplayToSingleSplitWindow’,0, 1920, 1080]);
I end up with mirrored displays at 60 hz. However, I haven’t been able to get the mirror to instead prioritize the ViewPixx 120 hz display.
If I set the resolution of the console monitor to be equal to the ViewPixx and select ViewPixx as the primary monitor in the display settings, I get errors that it is not able to measure the vsync and synchronization fails. I’ve pasted my X11 configuration below. My graphics card is a Radeon WX4100 and I am using Ubuntu 22.0.4 with Psychtoolbox 3.0.19.
