NUC6CAYH /screen turns occasionally black for a second

Jump to solution

Hi!

I'm having some issues with my brand new NUC6CAYH: The screen will randomly turn completely black for a few seconds.

This happens almost every minute. The NUC is hooked up to a display via VGA (resolution: 1920x1080@60 Hz). I'm not experiencing the same issue when I'm using an HDMI display (different resolution and refresh rate).

I have Windows 10 installed with the latest updates. The BIOS version is AYAPLCEL.86A and I applied this HDMI firmware update: https://downloadcenter.intel.com/download/26609/NUCs-HDMI-2-0-Firmware-Update-Tool-for-Intel-NUC-Kit... Download HDMI 2.0 Firmware Update Tool for Intel® NUC Kit NUC7i3BN, NUC7i5BN, NUC7i7BN, NUC6CAY .

I have also installed the latest graphics drivers (15.46.2.4729) but I got the same problems with the previous drivers.

Any workarounds? Thanks in advance!

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:

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.

 

 

Regards,

Just to be clear, I just purchased the NUC and the problem was there from the start.

The BIOS version is indeed 0040.

I didn't get the chance to try a different VGA cable. However, the previous PC that was connected to the same display with the same cable didn't have these issues.

I tried lowering the display resolution from 1920x1080 to 1600x900 and I'm not experiencing said flickering any more. It would be nice to be able to use the monitor's native resolution, though

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:

Hi!

Sorry for the late reply! I didn't replace the NUC yet since other people seem to be having same issues.

Just for fun, I tried running Linux Mint (live USB). The hardware setup was exactly the same (other USB devices, monitor etc.) but I didn't experience the same flickering @1920x1080. However, I only ran the live USB Linux for a very limited amount of time.

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.

Let us make sure we are using the same language: Flickering is an effect that happens constantly. Having a black screen appear for a moment from time to time is NOT flickering. So, what are you seeing?

Hello again. Ok, it´s nok flickering, but the screens turns black for 2-3 seconds, and then back on. One screen has just the VGA input, and another one has DVI/VGA where i use the VGA port. Just happens random and not under any strain. Surfing the web etc.

Hi, I have built and sold several of these units and have noticed this issue when using DSUB VGA to a 24" LCD . It's very random in its occurrence. What I have found when using HDMI is that the screen doesn't flick black but it randomly tears the image. Like a game would screen tear. This occurrence I imagine is causes the VGA to lose is signal when the HDMI port better manages the dropped frame.

Just to reiterate im Running latest Wind 10, drivers and bios. Have seen this on 4 of these models so far. Clearly intel need to look it to this asap.

I have seen the tear on the HDMI output. It is almost like a S/W-based bit shift that isn't getting enough priority. I have DVI monitor connected to the HDMI output, so it is not just HDMI monitors being more robust. I have another exact same monitor connected to the VGA output. I have NOT seen the black screen at all however.

So probably not related? I prefer the HDMI draw issue over the VGA black screen flicking. Do you think this could be fixed by driver or bios? Or is it hardware related? Could a RAM combination cause this prob?
