My Intel HD Graphics 620 driver just updated and killed my external display.
My system spec is:
System Model HP Pavilion Notebook
OS Name Microsoft Windows 10 Home
Version 10.0.16299 Build 16299
Processor Intel(R) Core(TM) i3-7100U CPU @ 2.40GHz, 2400 Mhz, 2 Core(s), 4 Logical Processor(s)
BIOS Version/Date Insyde F.25, 12/12/2016
SMBIOS Version 2.8
BIOS Mode UEFI
Hardware Abstraction Layer Version = "10.0.16299.15"
The Intel HD Graphics driver that causes the failure is: 184.108.40.20649. The symptoms are the external monitor goes black and reports that it cannot the resolution or refresh frequency. Altering the resolution and refresh frequncy makes no difference.
The way I resolved this is rollback the driver to 220.127.116.1142. Here is the procedure:-
1. Open the Device Manager - Type 'device manager' in the bottom left search box
2. Click and expand 'Display adapters'
3. Right click 'Intel(R) HD Graphics 620' to display the drop-down menu, and select 'Properties'
4. Select the 'Driver' tabs, then click 'Roll Back Driver'
This will rollback to the last version
