NUC6CAYH /screen turns occasionally black for a second

Mikkis: Thank you very much for joining the Intel® NUC communities. We are sorry to hear the NUC is not working properly.
 
You mentioned the latest BIOS version is already installed, just in case here is the link to download it, version 0040:
https://downloadcenter.intel.com/download/26899/BIOS-Update-AYAPLCEL-86A-?product=95062

Is this problem recently, did it work fine before?
By any chance, do you have the option to test the NUC with a different VGA cable?
 
We will try to reproduce this issue in our lab, as soon as I get any updates, I will post all the information on this thread.
 
Any further questions, please let me know.

Mikkis: Thank you very much for providing that information. I just wanted to let you know that we tried to reproduce this same issue in our lab using the same NUC and the VGA port and there were no flickering problems, the NUC worked just fine. And yes, you should be able to use the native resolution of the monitor.

So, in this case, it could be a defective unit. Remember the Intel warranty is for 3 years and if the problem persists then we recommend to replace the NUC.
If you are interested in that option, please get in contact directly with Intel:

I have the same issue. My display resolution is 1440x900 @60hz. I don´t have any hdmi display to try that connection.

I had upgraded bios and drivers to the latest but still the same problem

Coutma: In that case please submit your inquiry on a new thread, the reason for that is that every scenario is different, even if the same product is being used, so, for us to better assist you to try to fix the specific problem the computer might have, please submit a new thread:

Hi Mikkis: No problem at all. Thank you very much for letting us know those results. From our end the next thing to do will be to replace it, based on the fact that it works fine with Linux and when you used the HDMI port. The problem could be related to the VGA port itself.

Any questions, please let me know.

I encountered the same problem. On 2 different NUC6CAYH, same issue with VGA connection. Happens with different VGA cables, different screens, different resolutions.

No issue when using HDMI.

Hi.

I am having exactly the same issue with the same NUC model when connected to the VGA monitor at 1280x1024 60Hz. Running the Win 10 Pro and installed the latest BIOS and display drivers from Intel site. NUC has a date of manufacture 02-2017. Have not tried a HDMI connected monitor yet.

I did not want to create a new thread as the issue is exactly the same as described by original poster and sufficiently unique to make me believe that it is having the same cause.
