I understand that you are currently experiencing flickering problems when connecting the HDMI to DVI cable to the first HDMI port on the NUC.
Regarding this, I would like to begin by requesting an System Support Utility report, this is a report that you can create with our tool, you can download said tool in the link below:
Note: You can attach the report as a text file.
Also, I would like to request, if possible, a picture of the HDMI port labeled as "Protected UHD". I would also like to mention that, to me it looks as a problem with the adapter and the port you are connecting it to, the port seems to be a port dedicated to provide UHD, and the adapter's bandwidth seems to be insufficient to provide that kind of image/resolution.
I want you to please try to connect the NUC HDMI to HDMI straight, and see if the flickering issue continues, this is a testing step necessary to isolate the problem that can be affecting your unit.
Let me know the outcome please.
Thank you, David.
It does seem to be a cable/monitor issue. When I connect this port to other monitors it seems to work ok now. I am guessing the monitor I have is too old and not compatible. It is a Dell S2409 and I checked the label --- manufactured in 2009.
I had the problem on another monitor before but maybe the BIOS update or driver update cleared it. Seems to be working fine now. Thanks
