NUC7I7BNH picture and sound drops out for a couple of seconds

I have an intel NUC NUC7I7BNH acting as a media centre


plugged in via hdmi to a sony STD-DN1080, which in turn is connected to an LG 55UH850V


also via HDMI. I have an intermittent


fault (but it is happening frequently) where both the picture and sound drop


for 2 seconds prior to coming back on again.


It seems to happen most often when scrolling a web page from MS edge,


but will happen at other times as well.

Things I have tried thus far

  1. Change the HDMI cables
  2. I have tried to make sure that all of the


    drivers/software for the NUC, Amp and TV are up to date
  3. Ensure that HDMI control (CEC) is disabled for


    all of the devices
  4. Change the refresh rate of the monitor from 59


    hrz to 60 hrz
  5. I also tried disabling the generic P'n'P


    monitor, but I am not sure that this really worked as I couldn't find a suitable


    replacement drive.
  6. I have moving the NUC to a different input on


    the amp.

But thus far I don't seem to have found the answer. I wondered if there was anyone else 1) having


similar issues or 2) had any suggestions as to what to try next.

I have other sources connected to the AMP none of which exhibit


this behaviour

Elow: Thank you very much for joining the Intel® NUC communities. We are sorry to hear the NUC is not working as expected.

Even though you mentioned all the drivers are up to date, on the link below you will find the latest BIOS version: 0051 and the latest version: 4771 for the graphics driver, please make sure those are the versions currently installed on the NUC

We can also try to do the HDMI firmware update:

Which Windows version are you using?


Just for testing purposes, do you have the option to test the NUC directly connected to the TV, without the receiver? Just to confrim is the issue remains.

Any further questions, please let me know.

This is a common unresolved issue, there are over 400 posts discussing this here:


The bios version is already on 51 and graphics driver also on 4771. I tried the HDMI update but I was already on version 1.66 of the firmware so it didn't update,

I am running windows 10 which has all of the latest windows updates installed.

I tried to connect to the TV by passing the AV receiver and got a slightly different glitch (this time instead of the screen going black, I had it go fuzzy in an old fashioned static kind of way)

I guess I will monitor the thread /thread/116824 NUC7ixBN Screen Flashing/Flickering when using 4K resolutions
