Windows display update breaks HD Graphic 530 second video output

[FRich2]

Hi,

I have installed 10 industrial PC with the following specs:

- ASRock IMB-191 with Intel HD Graphic 530

- Intel i5-6500TE CPU, 8 GB

- Windows 7 Pro 64-bits

The 1st PC video output is connected to the PC internal monitor with DisplayPort.

The 2nd PC video output is connected to a remote display with HDMI.

All the PC have been running fine with the 2 displays during a few months, but the customer recently complained that they lost the 2nd remote display on the 10 PC after installing a big batch of windows updates.

I suspect the following update from Windows Update:

Intel Corporation - Display - 12/10/2016 12:00:00 AM - 21.20.16.4565

The issue was solved after rolling back the video driver to the old version:

- "Old" driver working: 20.19.15.4300 (1/10/2015)

- "New" driver not working: 21.20.16.4565 (12/10/2016)

Even though this issue is solved for now, I would like to check if this issue is known by Intel, and if future WIndows graphics update will break or not the 2nd display again.

I enclose the Intel System Support Utility results.

Thank you,

Fabien
