        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?

                  Just to chime in again. I rarely post here because I troubleshoot the NUC for a relative and don't have access to the device itself that often.

                   

                  The black screens are still there despite driver/BIOS/OS updates. Something I failed to mention in the original post was that the NUC is simultaneously connected to a TV via HDMI (1366x768@60Hz) and to said monitor via VGA. No black screens on the TV.

                   

                  Other peripherals/components used with the NUC include:

                  -Kingston SSDNow V300 120 GB SSD

                  -2x Kingston KVR16LS11/4 RAM sticks

                  -3G USB modem

                  -USB keyboard

                  -Wireless mouse (Logitech)

                   

                  Just wondering what components other people that have the same issues are using.

                    I am connecting my Nuc's via VGA single display out,

                    Clean install of Windows 10 latest build, installed Intel driver updater and installed all drivers/bios from there.

                     

                    I don't think I will order any more of these units until intel investigates the matter properly.

                      I have the same problem. Many others seem to have the same problem. It seems to be an intel driver problem. Driver seems to incorrectly set the screen refresh rate. We are all waiting patiently for a driver fix from Intel.

                        One of the other folks having this issue noticed that Windows had selected a wonky refresh rate for the monitor. After correcting this, the black screens stopped appearing. While you have a "bad" monitor connected, check what refresh rate is assigned. If it is incorrect, fix it and see what then happens. Let us know if this addresses the problem for you.

                            I have just now updated the BIOS from version 38 to 42. BIOS 42 is much more better - only one black screen so far. This is a big improvement.

                              I did have the same problem with BIOS 38. I’be just updated the BIOS to BIOS version 42. now I’m getting fewer black screen.

                                We have found a solution to the graphics flashing issue and the BIOS can be downloaded from here: Download BIOS Update [AYAPLCEL.86A]

                                  The BIOS update seems to have fixed the issue. Thank you!
