Hallo, mein Intel NUC7i3BNK gibt am HDMI-Port kein Signal raus, zumindest auf meinem Monitor. Bios-update wurde im Blindflug gemacht, er scheint zu starten und die blaue LED bleibt stabil an. Was kann ich tun? Gruß

During a BIOS Update, the Power LED should be blinking slowly, so I am not sure you were really accomplishing anything.


If the HDMI port on your NUC is dead and you still have an active warranty (check here: Determine if Your Product Is Still Under Warranty), you can have the base unit replaced. In this case, you need to directly contact Intel Customer Support to initiate the RMA process (you cannot do this through the forums). Here are pages where you can lookup contact information, including local phone numbers, by geography:



You can use the online forms service or email, but I actually recommend calling them directly. The above links provide local or toll-free numbers in most countries and support most local languages. You could also use the chat service (start here: Intel Customer Support Chat), but understand that this service is offered in English only and is subject to the normal (9:00-5:00 M-F) office hours in the Pacific (UTC-8) time zone.



If, on the other hand, your warranty has expired or you are secondary owner and have no warranty, this doesn't mean giving up on this NUC altogether. You can instead connect one or more monitors via the USB-C connector. This internally uses a DisplayPort 1.2 channel and thus is capable of supporting,


  • A single 4K monitor at 60Hz.
  • Two 4K monitors at 30Hz.
  • Two 2K monitors at 60Hz.
  • Three 1080p monitors at 60Hz.


Note: embedded links in discussion below are to examples that can be purchased on


For a single monitor, you can purchase a USB-C-to-HDMI Adapter or a and connect up that way. If you want to support a 4K monitor, look specifically for an adapter that says that it will support 4K@60Hz based upon a DisplayPort 1.2 signal (some say they can to do so, but then the fine print will say DisplayPort 1.4 is necessary to actually get 60Hz). If you want to support multiple monitors, you can use the aforementioned USB-C to DisplayPort Cable with DisplayPort monitors that support daisy-chaining or you can purchase a DisplayPort Multi-Stream Transport (MST) Hub device that supports two or three monitors, like this USB-C to Dual HDMI Adapter or this USB-C to Triple Display (DP+DP+HDMI) Adapter (add two DisplayPort to HDMI Adapters if you want all HDMI connections).


Hope this helps,

Hi @ORuec ,

1. Before you are sending back your NUC, I suggest you should try to update BIOS using BIOS Rcovery with The Yellow Security Jumper Removed method.  This process is executed automatically and you don't need to see video output to perform it:

2. Prepare USB stick fully formatted to FAT32 with Bios file . Format your USB with Quick Format option unchecked. Do not format your USB in MAC (OS) or Linux machine. Use Windows.

3. Disconnect the power adapter and remove the bottom panel from your NUC.

4. Remove the Yellow Bios Security Jumper. (page 55 in Technical Product Specification )

5. Insert the USB with the file into rear USB slot.

6. Reconnect the power adapter and power ON the NUC. Wait 30 sec - 2min. The Recovery process will start automatically and will end after 2 -5 minutes.

7. When bios recovery is completed, press and hold the Power Button to switch the power OFF, remove the power adapter and replace the Security Jumper (pins 1-2) . Reinstall the bottom panel.

8. Power your NUC ON.

9. Enter Bios setting by pressing F2 during boot process.

10.Press F9(followed by "Y"), to set Bios to default settings. Press F10 (followed by "Y"), to save the settings and exit to O.S. Let the NUC fully reboot.

Bios recovery was useless. So I contacted Intel support and they opened a case for warranty. Thank god these NUC have 3 years limited warranty, so last week I packed it well and sent it to Intel to GB. Intel payed for shipment and sent me a package note

On Monday a totally new NUC Kit arrived, the same model and I placed in memory modules and the M.2 SSD and It runs very well, I am totally satisfied with Intel and their very fast reaction
