So [NAME] , then you tried with the driver available from  [URL] In particular, with the 31.0.101.4109 it works on my 3 latitude. For one of my laptop, I tried also another option. I have de-installed the latest "DELL" driver 31.0.101.3959 by installing an older version always downloaded from the intel link above. In fact, these drivers from intel, in its installing program, have the choice to do a clean installation, by completely disinstalling all previous drivers, and I find this choice very applicable to our problem! Then I asked to the OS WIN11 to check for update, and it found the updated video driver 31.0.101.3959, ....so from WINDOWS 11 update and not the "DELL" version!   And actually, until now, it is still working with a dock WD19 and WD15 with three monitors
