    Windows display update breaks HD Graphic 530 second video output

    Fabien_r

      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
