I'm very sorry to read about the problems that you have with your new NUC. This is very new product and looks that the drivers are not fully debugged. I'm believe that in nearest future, Intel with cope with all problems. I've read in an other thread : Problems with 4k resolution on NUC7i5BNK that there are still different problems. In the mean time Intel suggest to roll back the latest graphic driver to the previous version: https://communities.intel.com/external-link.jspa?url=https%3A%2F%2Fdownloadcenter.intel.com%2Fdownload%2F26772%2FIntel-G…
I've got similar problems in a more or less similar environment - NUC7i3BNK, LG 55EF9509 on HDMI out and Yamaha RX_V1071 on USB-C due to not being capable of 4k and HDCP 2.2.
I did all the updates suggested by the intel driver update utility plus the HDMI update.
1. 3D doesn't work.
2. If I enable HDMI ultra deep HD color (in my TV's config menu in order to be able to show HDR) the resolution is automatically set to 3840x2160@60FPS and the screen starts to flicker. If I set to 30FPS for instance manually afterwards, flickering is gone. I guess this is a driver issue because UHD resolution and 60 FPS works when playing videos (from Power DVD 17)
3. If my UHD LG TV is connected to the HDMI port and my Receiver (hdmi 1.4) to usb-c (in order to be able to have HD audio and UHD) neither the Cyberlink Advisor will pass the HDR test nor the HDR mode will be enable when playing a HDR video in PowerDVD 17. If I disconnect the Receiver both will work.
4. ARC won't work if HDR is enabled
5. Even if resolution is set to 1080p I get short flickering sometimes
as the original poster, I tried several premium high speed cables with the same results.
Thank you for contacting the Intel community.
I’m really sorry for the issue you all have experience with the Intel® NUC, in this case if you already updated to the graphics driver version 184.108.40.20678, I suggest you to down grade to the version 220.127.116.1164, I have confirm that there is flickering issue with the latest driver 4678 because I have tested it myself and this has been already reported.
I also recommend update the HDMI 2.0 Firmware, you can download it here:
Note: This Firmware update is only required if an HDMI 2.0 device is being used. An HDMI 2.0 device must be connected when you run this Firmware update.
I have already down grade to 4664, and have no flicker now, but other power saving problems still exist.
I’m glad that the flickering issue has been resolved with the previous driver; please allow me to further investigate on this issue.
Turisto did the previous graphics driver solved the flickering issue for you, and does the video issue after waking the system from sleep mode is the same? If so, would you please attach your system information, to get your system information you can use the Intel SSU (System Support Utility) https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility:

- Download the utility
- Run the exe and select ‘Scan’

I tried 2 graphics drivers: 4664 and 4678.
Both have the same issues with HDMI signal after sleep. As workaround I had to setup power button to Hibernate instead of Sleep. After Hibernation the signal is back.
So each time I switch TV+NUC I have to Hibernate NUC first and switch it on again.
Flickering is gone, but I guess this is because I manually setup refresh to 30Hz. With 60Hz refresh rate I had flickering on 4664.
3D MVC playback doesn't work on both drivers.
Also very annoying issue: when Windows 10 initialises graphics after Hibernation or Power On, it always switches my TV's input to HDMI1.
But the problem is HDMI1 not connected to anything. My receiver is connected to HDMI2 ARC TV input.
So as result after windows loaded I don't have any signal on TV and have to manually switch it to HDMI2.
This is something related to CEC, but Sky Lake NUC didn't have this issue.
Mine flickers on 60hz too! is the problem being looked at by the tech team?
Thank you all this information and for your patience on this matter, please be aware that we will be investigating this behavior and ones we have a solution it will be post it here.
I have had may standby sleep problems in my NUC7i5BNK. Especially when there are USB mass storage devices plugged.
Thank you for the information WW6302, if you don’t have USB storage devices plugged is the system able to wake up without problem?
Would you all please provide me with the RAM part number that you are using on your Intel® NUCs?
Also, most of you are having this issue when connect to a receiver; if you connect the unit straight to the TV do you get the same problem?
Thanks for your help in this matter. My NUC is attached directly to the TV and I do have all the problems mentioned above.

Since I am waiting for my support case 02861457 being updated, and I have too much works to do with NUC, so I have set my NUC to NEVER standby and NEVER sleep. Without standby or sleep, my NUC is working normally. I will test what I posted as soon as my support case completed.
