Totally unacceptable and sad. Their spec sheets are really total frauds from what I can tell perusing this forum. Whether it's fake audio bitrate or 4k resolution support, it really is amazing that these things, which get billed as HTPC's, can't do these things. It really shouldn't be complicated to get 4k at 60Hz to work either, this stuff has been out a while and it's close to their flagship NUC.
Anyway, thanks David. I did downgrade to 4664 and it did nothing of course. I'm on the Creator's Update, latest patch available to the Current Branch for Business ring.
I had to downgrade Windows to Anniversary (the one before Creators) to get 4664 to make any difference for me. Even then, I haven't tested it enough since doing this to really be sure that it does fix the flickering. Still, being forced to downgrade Windows + a graphics driver isn't really feasible for a lot of people.
Also this issue doesn't seem to be unique to NUC devices -- it occurs on Macbooks 13 inch running Windows via Bootcamp, and Surface Pro with 4k 60hz external displays. Hopefully this issue is fixable with a software/firmware update.
I work for Intel Customer Support and I want to let you know that we are aware of screen flashing and/or flickering issue when using 4K resolutions on NUC7ixBN systems.
This issue has been reported and engineering is working on finding a solution for it.
I am trying to locate all community threads related to this issue to refer them back to the following one and consolidate: NUC7ixBN Screen Flashing/Flickering when using 4K resolutions <https://communities.intel.com/thread/116824> We will keep this community thread updated with any progress we make.
I apologize for any inconvenience this may have caused or is still causing and I appreciate your help and patience.
