Can't get display from Win10 PE on newer Dell Laptops

I tried to boot WinPE on Dell Latitude 7450 and Dell Pro Max 14 but can't get display from GL KVM.
But it can work well with old Dell Latitude 5410.

Wonder if this repair environment has secondary display enabled? Guess I'd try it with a monitor. You'd think it would have been enabled.

Might be how one made or got or uses the PE build??
