We are running on macOS.
We use a device called dualhead2go from Matrox to connect our video port to 2 external monitors. It creates a stretched desktop across two displays.
BlockquoteThe Matrox DualHead2Go Digital SE external multi-display adapter adds up to two monitors to your laptop or desktop computer. It connects to the video output of your system and uses the system’s existing GPU to provide high-quality, uncompressed graphics and video across all monitors. Ideal for business and professional users looking to increase their productivity with a dual display setup, this little black box lets you run different applications on each monitor or view one application across two monitors.
The problem we encounter is that when we use screen(‘openwindow’), it doesn’t open the right size. We want the screen to be stretched across two monitors, so that we can use stereomode 4 for the left/right eye viewing, but instead it always shows everything on the first monitor then duplicate it onto the second.
An illustration here is when calling Screen(‘Rect’), the system reports a size of 3840x1080, which is exactly the size of our stretched screen provided by the dualhead device. However after opening the window, it shows the window size is cut in half, meaning all the images are displayed onto the first screen, and duplicate to the second. This happens no matter what rect size I use in the open window command.
Is there any setting in the screen command that can help us stick to our original screen size?
