After updating the BIOS on our Dell Latitude 5420 laptops from BIOS 1.4.9 Release date 4/12/21 to latest version BIOS 1.5.2 it seemed to have broken the dual monitor functionality using the Dell D6000 docking units.
It also appears I cannot roll back 1.5.2 to 1.4.9 either. So how am I suppose to resolve this issue.
DELL please provide me with an new BIOS Update. Anyone else experienced this issue?
