Windows Update Display Driver Breaks PortFlex IO HDMI - EliteDesk 800 SFF G4 - Win 10 2004

EliteDesk 800 SFF G4

Win 10 2004

We use 1 of the 2 built in display ports for the monitor and then we have HDMI in the PortFlex IO port.

Yesterday some of the computers started getting from Windows Update Intel Corporation - Display -


Even before the restart of the computer, it kills the HDMI (PortFlex) port


Upon restart the driver fails to install per the Windows Update Settings page but is listed on the display adaptor itself.

The display adaptor is Intel 640 UHD 


Device Manager Rollback driver and restart; nothing

Device Manager Remove device and restart; nothing

Go into display setting and detect monitor; nothing

Go into Intel Control panel and detect monitor; nothing


Only way I was able to fix it was 

1) Install latest driver from Intel (100.8853) and Shut Down <--not sure if this is needed or not


2) Unplug all monitors on the built-it display port and plug a monitor into the HDMI (PortFlex)

3) Turn on computer and boot into Windows


You can then plug in all other monitors and everything will work. 


Anyone have an idea on whats going on here?
