I have a NUC6i7KYK running Windows 10 and have a BenQ XL2536-B monitor attached via HDMI.
As soon as the monitor goes to sleep the Windows start playing the "Device connected"/"Device disconnected" sound over and over again until I wake up the monitor again.
I have tried the latest GFX and monitor drivers with no success at all.
I run EventGhost and I can see the following events when this happens:
System.DeviceAttached [u'\\\\?\\DISPLAY#BNQ7F5C#4&2a735f64&0&UID200195#{e6f07b5f-ee97-4a90-b076-33f57bf4eaa7}']

Hi David,
Thanks for your answer.
I have been using the NUC with other monitors and was working fine. But I have also been using the monitor with other PCs(one with a NVidia 1080Ti graphics card) and was also working fine. It's the specific combination of this NUC with this Monitor that is causing the issue.
I reformatted yesterday to make sure it is not some software issue, but didn't help.
The information you requested are attached.
Thanks,
Stavros

Hi David,
Thanks for your reply. Will try an update and send you the new dxinfo.
I tried different cables, and using the Display Port instead of HDMI, but the problem is still there.
Thanks,
Stavros
