Not sure why but my first choice, Display Fusion, recently messing up screen refresh on high res Nvidia card 4k. especially Adobe Acrobat. Don't think it's incompatibility with Fences, but not sure.
DF had an indispensable function of setting independent Win 11 taskbars on each monitor.
Saw some posts in Oct that MS was going to add that feature soon. Is it in the beta or slow release versions?
