I can confirm that in Windows 10 display settings and in NVIDIA the main monitor is there and selectable. I have 3 monitors. They worked until I got a new main monitor. Now the left is fine and it shows a center main but it is not selectable in Display Fusion Taskbar Shortcuts. When I click the main monitor it shows the shortcuts on the right monitor. This is a problem since nothing I pin to the main monitor will work. Correction, some do but there is nothing obvious why some work and others dont. I have deleted all the pins based on other threads I have found that say to add them using taskbar shortcuts in Display Fusion but since it is apparently seeing the monitor but I cant click it and doing so only enables adding shortcuts to the right montior I have no clue what to do?
