We have resently put into production ProOne 400 G2 with an HP Elite Display E-202 connected via Display cable.
a few of the machines upon restart lose the second screen, yet the machine know's its there.
Only fix is disconnect the E-202, restart the machine. After the user logs back into the machine reconnect the E202 at the point, everything works as normal.
I suspect a driver issue.
Any Idea's?
