I have a really strange behavior.
Plugged to my LG Monitor, I do see the flickering as well on my NUC6CAYH
Other configuration, when I plug the NUC on my yamaha receiver which is connected to my sony tv, I do not see it anymore. BUT when I start or stop the NUC, My TV is switch automatically to HDMI1 . The funny part is I have no cable connected on HDM1 .... the nuc does on entry #4 of my receiver . The amp goes to entry #4 of my Sony TV.
needless to say, all drivers are up to date.

Thank you for joining the Intel® NUC Community. I am really sorry to hear you are having issues with these units.
I would like to take a closer look to the components and drivers of one of the units in questions, running the Download Intel® System Support Utility for Windows* will get that information. Regarding your questions, from our end we have not experienced this behavior is our CAY units; therefore, the replacement can actually address the issue. The only way to know for sure is to replace those units.
I purchased the Intel NUC6CAYH a couple of days ago, because it looked to be a solid HTPC with support for UHD HEVC 10-bit playback.
But instead I've been struggling with the HDMI display flickering all weekend, each flicker happening between a couple of seconds and up to several minutes.
When it happens I experience a full black screen and a full picture drop, then the display is restored again.
I've updated everything I could find; drivers, bios, HDMI firmware, TV firmware, AVR firmware.
Heck, I've even tried custom Windows 10 monitor.inf files.
The only workaround I've found (so far) is to set the refresh rate in Windows 10 to 1080p@30Hz instead of 1080p@60Hz.
I've been able to get a couple of hours of totally flicker-free viewing doing that, so I guess it's a good thing most media is ~24 fps.
Here's hoping someone at Intel figures this thing out, it seems like it's been happening for months.
