I just installed DF hoping it will resolve an issue I have with Windows 11. I have 3 exact same monitors all connected via Thunderbolt. The issue I have is monitor number 2 and 3 keep swapping their ID's. Pretty much every time I reboot these two monitors will swap IDs. I have DF setup to run my Monitor profile on startup but it doesn't do any good if monitors 2 and 3 are swapped. How can I fix this?

Is there anything that I can do to tie a physical monitor location to port or something?

How/when does DF get the monitor IDs from Windows? Please see the attached screenshot for the source of my confusion.

I too have the problem where taskbar shortcuts keep switching monitors. I figured the IDs were getting shuffled due to race conditions at startup (especially since I sometimes run up to three monitors through USB). For example, in the screenshot, the shortcuts for Windows's monitor #1 are being displayed on DF's monitor #1.

In any case, the screenshot clearly shows that DF's numbering is different from Windows. Restarting DF doesn't change anything. Is there a way to sync them up? Are the deactivated monitors somehow confusing DF?

Edit: I did some experimenting. Unplugging the USB connections for the two deactivated monitors, and then restarting DF, changed the DF numbering from 4-5-1 to 2-3-1. Only when I then rebooted Windows did the two sync up.

Any clarity on how this is meant to operate would be appreciated.

Interestingly, one of my USB monitors died on me. With only two USB monitors it doesn't seem to be an issue, or at least I haven't been able to reproduce it. I'll post again if it changes before or after I replace the monitor.
