jchapple: Thank you very much for joining the Intel® NUC communities. We are sorry to hear the NUC is not working as you expected.
You mentioned, the latest drivers and the HDMI firmware are installed, just in case here is the link where you can find them, the driver version is 4729:
We can also try a BIOS update to the latest version 0049:
Just for testing purposes, do you have the option to test the NUC with a different HDMI cable?
In order to better assist you:
What is the model of the TV/Monitor?
Are you using graphics converter/adapter? If yes, please provide the model of them.
Please describe the connection you are working with, for example : “NUC is connected to the HDMI input of the receiver; the receiver is connected to the HDMI input of the TV”.
Any further questions, please let me know.
Many people having these issues including myself.
To get all the 6 digital audio formats to work (no Atmos for my avr) and audio settings in Kodi set to Wasabi:Default and passthrough, then under that the capabilities of the avr all 'boxes' ticked. I had to set the sound properties on the NUC set to default which is 16 bit 48000 hz,
I am still experiencing the issue. As I already mentioned in my original post, all drivers and HDMI firmware are up-to-date. Already outlined the setup in original post. Not prepared to bother trying out cables as previous setup with same cables was 100% OK.
Other people experiencing the issue.
Clearly a Graphics driver / HDMI firmware issue.
Can I provide any more help?
Also, my initial suspicion about the cause being due to overall HDMI bandwidth is probably BS, as also occurs on ordinary bitrate streams (e.g. 1080p, 24hz, stereo PCM).
What I *have* possibly noticed is that restarting the machine may temporarily alleviate the issue, but its intermittent, unpredictable nature makes it hard to say for sure. There are periods where it does seem to get very bad (blacking out maybe 4 or 5 times every minute), which is when a reboot is required.
jchapple: Thank you very much for providing that information and we apologize for any inconvenience. We will do further research on this specific scenario in order to try to find a possible solution for this issue. Based on that, you mentioned you are using a Vizio TV, could you please provide the specific model of it?
Any questions, please let me know.
Certainly. It is the VIZIO D65u-D2.
jchapple: Thank you very much for providing that information.
Yes, it could be related to that same issue on the link you gave us, and since you already updated the BIOS to 0049 version we will start a research in order to try to fix this issue.
Just to complete the information about the configuration that you are using, what is the model of the memory RAM on the NUC? If it is possible please provide the size and speed.
Also, what is the model of the hard drive/SSD on it?
As soon as I get any updates on the research, I will post all the information on this thread.
Any questions, please let me know.
Thank you for looking into this.
The memory used is Crucial 8GB Kit (4GBx2) DDR4 2133 MT/s (PC4-17000) CL15 SR x8 Unbuffered SODIMM 260pin (Mfr part code: CT2K4G4SFS8213).
The SSD is a SanDisk Pulse 64GB SSD (SDSSDP064G).
I know that you are aware of the following issue described in this forum: NUC7ixBN Screen Flashing (screen turns on and off) when using 4K resolutions
..and this is what I recently posted:
"The best combination for now is BIOS 49 (latest) Download BIOS Update [BNKBL357.86A] and Graphics Driver 220.127.116.1164 (Previously Released) Download Intel® HD Graphics Driver for Windows® 10 for Intel® NUC Kit NUC7i3BN, NUC7i5BN, and NUC7i7BN. Make sure all other drivers and firmware (specially HDMI 2.0) Download HDMI 2.0 Firmware Update Tool for Intel® NUC Kit NUC7i3BN, NUC7i5BN, NUC7i7BN, NUC6CAY are updated to latest version. This combination seems to work fine and it has been reported as stable by folks here is this community thread and I have also tested it and had no flickering (thanks TX for your recent post with this recommendation)
I have not been able to find any corelation to Windows 10* updates, I am running Windows 10 1703 https://support.microsoft.com/en-us/help/4018124/windows-10-update-history with the combination mentioned before and I have no flickering but Fire00 is also recommending Windows 10 16xx version, this may also help (thanks Fire00 for the recommendation)."
Is it possible that you roll back your Graphics driver to 4664 and see what is the result?
I am not saying it is the same issue but it seems 4664 is a lot more stable than newer releases.
